Apex Legends is not locked to 144 in the game engine, rather it runs with vsync on and is then limited by the refresh rate of your monitor. The game engine's cap is 299 fps. To enable this in steam you can add the phrase "+fps_max Unlimited" to the input box for launch options under properties tab on the game. This will allow you to get the uncapped frame rate. The a4000 should be able to max this game out in 1080p low/med. Otherwise great video and good content!

Thanks! I appreciate the feedback. I would love to be more frequent. Problem is finding a place to record my videos. I currently do not have the space at home to record content, not enough room! I've resorted to making a deal with my workplace to use an occupied office to record my content. Makes things tricky to setup and film!

Nice, I'm currently fixing up an A4000 that I got for cheap because it had some trace damage (it fell onto something sharp and gravity did the rest), and this is the first video that actually combines the cooling mod with a shunt mod + shows all the results. Great video, It's going on my bookmarks for future reference👍

[@WiltshireTutorials]

Glad to hear that you're taking the time to revive and keep that A4000 going! I plan on doing some more gaming benchmarks in the future in another video. I'm taking 30+ games that people can sift through. I'm also happy to hear that you liked the video so much as well

Freaking awesome content. Just found your channel and this was one if the best tech videos I've seen in a while for modders and enthusiasts. Did wish there was more games tested and on a 4.0 mobo with OC RAM to really see the unlocked performance in games but that is one slick looking card modded it looks like OEM. Beautiful work. And just saw your additional video which did all the things I just critiqued lol. Wicked. Subscribed

Thanks for the kind words, John. I try my best! I'm glad you like the content! I really appreciate the sub, it means a lot.

[@titaniummechanism3214]

I played around with an A4000 today, which was unmodified except for a waterblock. I could set +220Mhz on the core and +1000Mhz on the memory and I probably could've gone further. The problem was, that due to the stock power limit, the card wouldn't boost to the clock that I had set. Lack of power causes throttling, not crashing. Unstability due to high clocks or insufficient voltage is the cause of most crashes when OCing. Also, I personally wouldn't have bothered replacing the stock power connector. Unless you're doing XOC on an A4000, the 6Pin should be sufficient. But I wouldn't feel comfortable pulling more than 75 W trough the PCIe slot.

[@WiltshireTutorials]

I'm able to get 260MHz+ on the Core and 2000 MHZ on the memory. The 8-pin is way more clean. You don't have the soldered on 6-pin dangling off the PCB. The solder could crack over time from it dangling. Plus the added ability to overclock more, if needed, is a nice plus. The shunt mod doesn't draw more than 75W from the PCI-E slot? It's not an A2000... It gets the rest of the power from the 8-pin. Which is why we swapped the the 6-pin to an 8-pin. It would be different if you were using an A2000, but the A4000 is a different story when it comes to PCI-E slot power draw.

[@titaniummechanism3214]

​@@WiltshireTutorials The pcie 6 Pin has the same number of +12V lines as the 8Pin and both are known to be able to deliver far far more power than they are rated for. You'd sooner kill your GPU than exceed the limits of that 6 Pin. But I'm not so sure that the PCIe slot can handle much more than it's rated for. And that's why I wouldn't have shunt-modded the PCIe slot and why I wouldn't have swapped the 6 Pin for an 8Pin. Also my waterblock has a spot for housing the 6Pin, so I would have to modify that as well.

[@WiltshireTutorials]

The PCI-E slot, much like the 6/8-pin, can handle more than it is rated for. The amount will vary depending on motherboard manufacturer and their power delivery setup. If they cheap out on the power delivery, wouldn't recommend it. If the board has a decent power delivery it'll be just fine. I've tested this extensively, as I daily drive 2 shunt modded GPUs; the A4000 and the A2000. Both haven't kicked the bucket, nor fried a motherboard. As for the waterblock, the PCB layout is the same as an RTX 3060 from Palit or PNY. So, that waterblock will essentially fit the A4000.

[@kksjohn2k7]

Glad you liked the video! I'm trying to get my hands on a something that will allow me to re-visit this with PCI-E 4.0 and RE-BAR. Very curious to see the uplift in performance with both of those.

[@rothein436]

Great content, just watched all of the optiflex series in a row and the modding is so cool. Maybe a 4070 twin edge will fit in the optiflex as it only 0.4 mm longer then the previous 3060 ti

[@WiltshireTutorials]

Glad you liked the content! I appreciate the support. As for the 4070 Twin Edge, it may fit. The length is not an issue, it's the height. The 3060Ti fits, but the PCI-E power cable is pressed up against the side panel. The 4070 would probably fit, but the stress on the power cable may be a bit much

Really nice to watch a video in which a guy understands that his CPU ram pcie combo will reduce the results a bit, (Vent below feel free to not read any of it) But don't worry this ain't the worst of the systems I'm currently running my unmodded rtx a4000 on a Ryzen 7 5700x , asrock ab350m HDV r3.0 , pcie 3.0 , 1x 16gb dual rank 3200mhz ram stick at 2666mhz , infinity fabric at 800mhz instead of 1800 , rebar enabled With 3200mhz on ram - system shuts down once every 1-2 weeks during heavy CPU tasks With 2666 still testing.. Mobo is horrible, it can't handle infinity fabric, it can't handle dual channel ram with infinity fabric, no voltages help 800mhz on IF is the lowest with what system can start, 933 IF shuts the system down in less than 10 minutes of stresstest 800 IF passes 3h stresstest 667 IF = CMOS battery removal If 2667 mhz will still shutdown pc every once in a while too I'll try bclk oc in hopes to get e.g. 733 IF and to hopefully boot with that Asrock HDV series are horrible, only their latest one is actually good for Ryzen 7000, rest are tra*h Anyways I've upgraded from r5 1400 , which I ran with -100mhz and manual volts due to mobo's vrms degradation (it ran 2 ram sticks at 2667 just fine though but there was no IF on it) Miracle I've even managed to make all 8 cores of 5700x to work at 4.1ghz , small yeah but that's vrms 2x 16gb dual rank ram at 3200 with 1800 IF in dual channel worked only if I disabled 6 out of 8 cores , fun times But well obviously I knew that I will face issues by upgrading on that same tras*y mobo Originally I just waited for 7950X3D but after Steve's review from gamers nexus I decided to keep waiting And bought cheap 5700x to wait it out. Maybe 2x 8gb sticks will work when 2x 16gb don't, I know that's a thing sometimes, but currently I don't have any spare ones and my neighbour is using aio which prevents his ram from being taken out so just gonna wait it out till new CPUs and GPUs, I'm from EU so unfortunately will not order the power mode for a4000 Btw 5700x @4.1ghz, single channel (3200mhz, old data) and 800mhz IF was still like 60% faster if not more in all the games than r5 1400 @minus 100mhz , dual channel 2667 , no IF So my super painful temporary upgrade has worked out And yes I tried re-seating CPU, wasn't it, just bad mobo.. Sorry for the vent

[@WiltshireTutorials]

I try to be as informed as possible when making videos. Thanks for noticing. We've all been in here. Always sucks when you're fighting with a motherboard to cooperate. Have you tried updating the BIOS on the board? That has fixed some major problems for me in the past. Give it a shot. You may also want to give your RAM just a touch more voltage than the stock. That's helpee me in the past before as well. We're talking .01 more volts not much more than that.

[@cskillers1]

​@@WiltshireTutorials unfortunately i'm on the latest & the only bios version which supports ryzen 5xxx , it's from 2 or 3 months ago and was even a surprise that they've added it, highly doubt that they will release any further versions for it, all the voltages i did tried already, no luck ram volts, soc volts, infinity fabric volts, tried all possible volts, more than wrote here, and unfortunately they gave 0 benefit, some volts even raised instability if they were ramped up too high which is expected, tried timings too but seems that this mobo just can't do infinity fabric that well so only thing i can do is just bclk oc to further reduce IF to e.g. 733mhz since this mobo can do only 667>800>933>1066 and 667 = bios battery removal, 933 = less than 10min of stresstest & shutdown, 1066 = 2sec of stresstest & shutdown , 800 passes 3 hours of stresstest but seems that it can still shutdown once every 1 or 2 weeks if ram stick is at 3200mhz, so trying 2666mhz first(doubt it will help because at 933IF i tested 2133mhz on single stick and there was no difference, it still shut the pc down) so may end up doing bclk soon since some IF like 733 may boot and may completely 'solve' the issue, of course i understand that it's just a workaround, buying some used yet decent $80 mobo would completely solve all the issues and i would be able to use 2 sticks of ram, maybe 2x 8gb sticks would work on my current mobo as well without issues since i know that some mobos are bad at handling 16gb ddr4 sticks but that's money too but well at least i can wait some more till some better cpus than current high end ones will be released, intel is too power hungry, amd cheaped out on putting cache on only one ccd here's my timespy results on slightly nerfed r5 1400 + A4000(without manual volts curve) and this super nerfed 5700x by everything mentioned before + A4000(with manual volts curve) www.3dmark.com/spy/36465637 www.3dmark.com/spy/36801723 of course i wasn't using a4000 with an r5 1400, that would be dumb, i was using it with an r9 390 for a long while which was a more doable pair though i still found myself being cpu bottlenecked in multiple games so just did the bench for fun, btw due to nvidia's driver overhead - i had around 40% more fps in one cpu intensive game with r5 1400 + amd r9 390, than with nvidia A4000 + r5 1400 , obviously once i inserted 5700x that issue completely disappeared, but it was fun to see the driver overhead in action (cpu was nonstop 100% usage with nvi gpu where's with amd gpu it was 90ish with occasional 100) so because difference is that huge, it's recommended to use amd gpus on old/weak cpus (or old nvidia gpus&drivers before 2021 i think? forgot when that driver overhead became a problem) also gonna use this opportunity to share my old Time Spy , Time Spy Extreme & Fire Strike Ultra results, i am actually ranked #1 with 4x R9 390's in all 3 of these xD , cpu was used very poorly in these tests because it seems that it doesn't like dual ccds or just too many cores , sold all of these 390s cause CFX is dead, but it was a really nice experience, mobo of TR died so that's why i was using an r5 1400 before the 5700x www.3dmark.com/spy/10554649 www.3dmark.com/spy/10553928 www.3dmark.com/fs/21416957 don't want to waste your time any more man :) gonna sub for possible epic content, good bye!

Do you know the thermal pad thickness used in the mod? I’m planning to mod my card with a Noctua fan and it would be good to have some spare pads just in case :)

If I can remember off the top of my head, the thermal pad thickness is 2mm

[@herc1319]

So you used the Inrobert kit for the upgrade? Also any improvements in temperatures? And is possible to change out the stock fan for another fan

[@WiltshireTutorials]

No kit was used. Just bought a PNY RTX 3060 cooler and swapped it. As the PNY RTX 3060 and A4000 use the same PCB layout. The thermals are much better than the stock cooler.

[@DeltaHQ]

Get the inRobert. Its the same PNY heatsink.

[@Hurricane_7734]

Fantastic mod. What is average FPS increase % compared to stock 3060 ti?

[@WiltshireTutorials]

In benchmarks, I saw about 19% increase overall vs the 3060Ti. For gaming, I saw about 12% increase. Granted, all of these tests were done on my modded Optiplex. So, I'm willing to bet that the increases will be much better with a PCI-E 4.0 motherboard that has REBAR as well.

[@CornBreadMan264]

In the future, would I be able to order just the 8pin mod & SFF cooler WITHOUT the shunt mod? I just want to run it at it's stock speeds with no plans of overclocking.

[@WiltshireTutorials]

I don't think that is offered from JK&G Ventures. But, John is very easy to work with over there and you could personally contact to work out a deal. You don't need the 8-pin mod, if you plan on not overclocking at all. The stock 6-pin will work just fine for you. You could just swap the cooler over yourself and away you go. Just make sure to order the PNY RTX 3060 Heatsink, if you're going to do it yourself.

[@CornBreadMan264]

@@WiltshireTutorials Well, I would prefer the security of the 8-pin as I don't want the wires from the 6-pin being cut accidently by the heatsink. And I'm not a expert when it comes to swapping out coolers for GPUs.

[@WiltshireTutorials]

@@CornBreadMan264 It's fairly straight-forward to swap the cooler. You don't need to be an expert for the A4000. It's very easy to do. As for the 6-pin cable, you can trim 2 fins off the heatsink with side cutters to allow clearance for the 6-pin power cables and not have them be pinched.

@@WiltshireTutorials Unfortunately that's life buying used mining cards. Mine's under water in a 6L NFC Systems case, but even so it would have thermal headroom to stretch its legs a little more if the silicon allowed. Regardless, the A4000 is an epic little card.

@@Passchen Big fan of NFC cases. Are you using the O5L? I may attempt to water cool the A4000 at some point, to see what kind of performance gains I can get. I'm almost positive my A4000 was also used for mining. The seller wouldn't confirm nor deny if he used it for mining or not. Judging by how dusty mine was when I got it, almost confirms it was used for mining.

[@J.I.R.A]

Hey mate! Sorry for asking so many questions 😅 At 2:00, the 195.29W includes the overclock on top of the modding, right? Could it be undervolted like a standard RTX3000?

[@WiltshireTutorials]

No need to apologize. That's what I'm here for. That's correct. The power draw of 195.29W was what I saw under 100% while overclocked. Undervolting the shunt mod is a little counterintuitive. It'll basically undo everything that we've done with the shunt mod. The shunt mod shoves more power into the GPU die bypassing the power wall/ceiling put in place by Nvidia.

[@J.I.R.A]

@@WiltshireTutorials thanks! Alrighty, so this would be a fit it and leave it type of situation right? There wouldn’t be an option to tinker with it using afterburner to set a fixed voltage and frequency and maybe drop power to ~170-180W while retaining most of the performance? I’m mostly worried about temperatures under continuous 100% gpu utilization during extended periods of time.

[@WiltshireTutorials]

@@J.I.R.A the hottest I saw was 75°C at 80% fan speed. This was overclocked as well. The modded heatsink does so much better than the stock one. You can tinker a little bit in Afterburner. However, the RTX A4000 locks out the core voltage and power limit sliders to 100 max. You cannot adjust them any higher, only lower. You'd have to find a way to modify the VBIOS of the card, which no one has figured out how to do yet. You don't have to overclock the card, like I did. You can just drop the card in with the shunt power mod and you'll still see a performance gain of up to 14%

[@J.I.R.A]

@@WiltshireTutorials that’s not bad at all in terms of temps! Can you access the vf curve in MSI Afterburner? Also, may I ask how you went about overclocking the card?

[@WiltshireTutorials]

@@J.I.R.A You can access the curve editor. However, I found that it doesn't do much. I saw no difference when making changes to the curve. I think it's a byproduct of the shunt mod. As for overclocking, I just simply adjusted the memory clock and core clock using MSI Afterburner.

[@pulp2560]

Next step, find a way to mod the hp bios to enable rezable bar.

[@WiltshireTutorials]

It's a Dell Optiplex in the video. It's a little more complicated with the Optiplex. Dell makes you update the BIOS via a .exe file and not a regular BIOS file. So, I would have to find a way to decrypt the .exe file or hex edit it, change the content of the BIOS file and re-wrap it back into a .exe that the motherboard will accept. I believe it has an MD5 Checksum to verify the correct BIOS is being flashed as well. So, that complicates things as well.

[@KSINGRAM]

Do you guys know what pci bracket will fit this heatsink so I can screw it into my case?

[@WiltshireTutorials]

The modded A4000 cooler should allow you to re-use the PCI-E brackets from the stock A4000's heatsink.

[@Punkboi2]

could you upload a step-by-step soldering tutorial for this mod? first time building an itx and highly interested in not breaking my used A4000 😂

Soldering isn't my specialty, so to speak. I'm decent at the soldering, but not the best. For me to make a tutorial on the power mod, I would need another A4000 to work on.

@@WiltshireTutorials I am specifically interested in a the RTX A4500. It goes for around $100 more than the RTX A4000 so a used one should yield some good results.

[@WiltshireTutorials]

I'll take a peak at the A4500 PCB to see if it has similarities. If it looks like it can be done, I'll investigate it!

[@SiGeTVee]

Does this require special drivers or can you download the official RTX A4000 drivers from Nvidia and leave it at that? Do I have to manually dial in the "modded clocks" setting or will it do it on its own stock? I have a Skyreach S4 Mini that currently houses a 3060TI Dual Mini. Been thining about waiting for the RTX 4000 Mini series to come out from the board partners, but seeing this exceed the 3070TI right out of the gate has me intruiged.

[@WiltshireTutorials]

Good question! I should've mentioned that in the video. The driver I was using was the official one from Nvidia. More specifically I was using the driver version R530 U1 (531.18). As for the clock speeds, you can choose not to overclock the card and keep the stock clocks on the card. By using the stock clocks, you'll see an improvement of up to 14%. You can push the card more by overclocking it to get up to 36% increase in performance. The most stable overclock settings I found for daily usage was: Core Clock +200MHz & Memory Clock +1000MHz Since you're using a Skyreach S4 Mini (awesome case by the way! Big fan of NFC and Josh!), overclocking may make or break things due to power limitations of your Pico PSU. I mentioned the amount of watts the GPU was pulling in the video. You can go higher than that, as evident by my benchmarks, but not all games will be happy running at such high clock speeds. You'll see that my clock speeds varied game to game.

[@SiGeTVee]

@@WiltshireTutorials I am not using a Pico PSU. In fact, I'm using 2 of HDPlex's new modular 250W GAN PSUs that are connected to each other via sync cable: hdplex.com/hdplex-fanless-250w-gan-aio-atx-psu.html (One GAN is connected to just the GPU, the other GAN is connected to the Motherboard + CPU.) I can run a 3060TI comfortably and perhaps even a 3070 should I be able to find it in a similar 200~mm form factor. (Right now, I'm using an ASUS DUAL MINI RTX 3060TI for my S4 Mini.) I guess my main issue would be finding a way to secure an RTX A4000 for cheap, on top of the cost of modding it...which right now would cost more than $1k for a brand new A4000. I guess I can just stick with stock settings given how it will still see a performance uplift, but given the costs I might have to reconsider between this solution or waiting for a much more consumer-friendly approach of getting a 4070/4060TI Mini for potentially much cheaper (hopefully), not to mention the Ada Lovelace cards having newer feature sets too (DLSS 3, AV1 Encoding, better RT performance). Edit: I kind of wish instead of using the Palit single-fan shroud, it uses ASUS' Dual-Mini fan setup, which uses two fans and still amanges to fit inside an S4 Mini.

[@WiltshireTutorials]

@@SiGeTVee That's a sweet setup for the power supply to the S4 Mini! Very cool to see the modularity for the HDPlex! That is very true. Trying to find a decent deal on the A4000 is difficult. I was lucky to find one for a pretty decent price. $475 CAD is what I got mine for. Hopefully Nvidia is nicer when it comes to pricing of the 4070 or 4060 Ti. It's taken them a while to get them out into market. The better encoders and RT performance would be really nice for me. I find not a lot of people will take advantage of the AV1 encoder or the faster RT performance though. There is another mod you can do to the A4000 to give it 2 fans instead of 1. You can slap on a Gigabyte cooler instead of the PNY cooler.

[@SiGeTVee]

@@WiltshireTutorials I forgot to mention that I'm pretty scared of doing these mods myself! It was pretty nervewracking trying to assemble my S4 Mini, but at least nothing had to be soldered on. I know some of these mods use liquid metal as well, which I've never worked with. I don't know how much it would be to purchase a premodded A4000 with a Gigabyte cooler, but at this rate I'll probabaly end up just waiting for ITX variants of the newer GPUs.

is drawing that much extra power even safe? i would think that something may blow from the extra wattage, but i guess the alternate cooler offsets that a bit

Yes, it is safe. Here's why; the RTX A4000 is essentially built exactly the same as an RTX 3070Ti, which draws approx. 310W at full load. Also, the shunts put in place by the PCI-E connector prevent the GPU from exceeding the power delivery limit of 75W on the PCI-E slot. All the extra power is coming from the 8-pin PCI-E connector, which it can handle just fine. The 8-pin is rated for a max of 150W on its own and the PCI-E slot is 75W. Add them together and you get 225W. The card will draw a maximum of 205W with the shunt power mods in place, leaving 20W of headroom.

@@WiltshireTutorials oh wait, they also reused the 3070ti vrms? i thought the a4000 was just made out of the 3070ti cores that failed binning tests, and otherwise used 3060/3050 equivalent parts for the board.

[@WiltshireTutorials]

@@quantum5661 as far as I'm aware, the VRMs are the same. The A4000 is essentially a super efficient 3070Ti

[@kaiateisenbahn4112]

​@@WiltshireTutorials Is the VRM layout for the 3070 Ti Fe not completely changed? The RTX A4000 has by the look of it a similar VRM design to the the 3070 Non-Ti Fe but three stages less. They get get already toasty with 140 Watts especially with the stock cooler which blows the hot air towards them. The reason why this card loses good amount of performance under long heavy load because the vrm effiency drops significantly when getting hot. Maybe one can measuring the PCB backside temperature in the VRM environment with a infrarot thermometer?

[@marekwisniewski5572]

@@WiltshireTutorials I don't understand -why you need to change shunt for PCIe slot ? in stock configuration this shunt should be fixed t 70W since PCI-E slot on motherboard can draw only 70W according to specification of ATX mother boards. The only problem is to limit correctly power draw from 8 pin connector t prevent more than 150 W power draw. But as far I can see on JK&G pictures the shunt near 8pin connector is swaped to copper bridge to allow FULL 8pin connector utilization with no limits. PCIe shunt near Pcie slot is swaped but can't figured out why and what is the resistance of it.

[@cryptosol160]

6mOhn resistors on PCI-E and 8-Pin? I got this A4000 card and with help of one cool man from reddit get it shunt modded. So I'm more interested in details. Exact curve, max consistent clocks, power limit wall, BIOS version (OEM brand), that kind of tech shit.

[@WiltshireTutorials]

To be honest, I'm not sure how many Ohms the resistors are. I was highly advised not to use any voltage curve and to let the A4000 do its thing. The clocks that I found to be the most consistent and stable were +200MHz Core Clock and +1000MHz Memory Clock. Some games were able to run at higher clocks and some preferred the clocks stated above. Obviously, this will vary depending on the quality of silicon that you have for your card. My A4000 brand was Lenovo and the BIOS version for my card was 94.04.57.00.0A Hope that answers your questions!

[@cryptosol160]

​@@WiltshireTutorials Thank you for responding! It seem where is no shunt on NVVDD resistor on your version of mod. Also it would be cool to add temperatures and power draw.

[@WiltshireTutorials]

@@cryptosol160 I mentioned temperature and power draw quickly in the video. About 75C on the Core while overclocked and I observed about 195.3W of max power draw.

[@marekwisniewski5572]

@@cryptosol160 I can see that there is no Shunt on NVVDD - the factory shunt there was replaced by copper plate connection to allow full power draw ( so I think there is very low resistance ) only shunt that was changed is this near pci-e connector

[@DmitriWeissman]

While cool, i see this shunt mod kinda useless. I replaced the cooler because it was annoyingly loud. I soldered the power connecter because of my OCD for things to look nice. But that shunt mod ... Like you show gaming performance increase of under 15%. Lets say with rebar it would be 20%. It wont change the experience much. Though just for fun, I might do half old-school shunt mod by applying liquid metal on top of the existing resistors.

[@WiltshireTutorials]

The Dell Optiplex that I was using in th video, named OptiFlex, was the bottleneck for the A4000 with the shunt mod. I tested it on much newer hardware and found I got even more performance gains. Check out that video here: kzbin.info/www/bejne/qZvRe5ignah-iq8si=nFVUa0auxBIe8nTV

[@DmitriWeissman]

@@WiltshireTutorials Thanks for the reply. There is a little flaw in that video. For the fair comparison, the results of unmodified A4000 on the new system are missing. I understand that you don't have the unmodified card anymore :) It is kinda safe to assume that the unmodified card would perform a bit better on the new system. Especially in the 1% and 0.1% lows. We can look at the teckpowerup's review of 3070Ti and see, that there is a 12% and 16% lead over 3060Ti at 1080p and 1440p respectively over large number of games. And this would be an ideal unmodded vs modded card difference. I mean it is nice and fun to do the mods and overclock, but the practicality of it from performance improvement perspective is questionable at best. I think (and actually did it myself) that the cooler replacement is a great idea and great value. But starting with soldering the PCIe power connector and going with modifying shunt resistors is pure fun with great risk of damaging/killing the card for the very little practical gain. As a side note, I think that 3070Ti is a worse card due to the VRAM capacity even with higher average performance in most games.

[@WiltshireTutorials]

@@DmitriWeissman the things you pointed out are correct. It's definitely safe to assume the unmodified card would perform a little better on the newer and better hardware. I did compare the 3070Ti to the modded A4000 at 11:51. If I had the card on hand, I would love to do a comparison between the A4000 and the 3070Ti.

[@boomshaka918]

I'm confused what is the purpose of doing this?

[@WiltshireTutorials]

Allow me to try and explain things for you in greater detail. Feel free to ask any questions, if you have any after my explanation. I'll do my best to answer them for you. A shunt is the resistor on the GPU that regulates the amount of power coming into the GPU die from both the PSU and the motherboard. This card is shunt limited to 140W from the factory by Nvidia. This essentially stops the GPU die from reaching its full potential for speed. For the GPU die to run faster, it requires more power to keep the GPU die more stable and from crashing. It's a fine balance though. More power coming into the GPU die and the VRMs will cause the card to output more heat. That's where the new custom heatsink comes into play, to deal with the increased power draw. A VRM is a series of voltage regulator modules. Their purpose it to take the 12V coming from your power supply and convert them down to a lower voltage that ranges from 1.1V - 3.3V. By adding more power, they get warmer too. The purpose of the mod is to bypass those artificial power limitations set in place by Nvidia and unlock the full potential of the GA104 GPU die. Nvidia sometimes likes to put artificial barriers in some of their products, even though they share most of the same components under the hood. This is to cause a market gap or to increase the efficiency of the GPU. By adding a different shunt resistor and changing the resistance, it allows the card to draw more power to increase it's clock and memory frequencies. Thus allowing the card to run at its full potential. With the changes made in the video, we increased the power draw from 140W to aprrox. 205W. Another purpose of the mod is to create the fastest and smallest form factor of GPU. The SFF (small form factor) market segment has largely been ignored by both AMD and Nvidia. Making it difficult to make a SFF PC build these days. After installing a different, much smaller heatsink, we've decreased the physical footprint of the card. Allowing people to create smaller PC builds. Believe it or not, the modified smaller cooler is better at dissipating the heat coming from the VRMs and GPU die. In the case of the RTX A4000, they used the same GPU die as their RTX 3070 Ti, a much faster card, and dialed back the power draw on it. By doing so, it allowed Nvidia to created a super power efficient card for workstations. This is a good thing in most scenarios for businesses, if they have multiple workstations constantly turned on drawing power. Power can be really expensive in some countries, Germany is a good example of this, so this can be desirable by some companies to save money. But it comes at the cost of the GPU die's performance. It depends on what you're after. Do you want more efficiency or more performance? Hope this detailed explanation helps! Thanks for watching.

[@boomshaka918]

@@WiltshireTutorials Wow didnt expect such detaiiled explanation. I still wouldnt do all this it seems like the amount of money going into this, plus the rrisk of messing up the card, and also the increased power draw wouldnt be worth it to me just my opinion. Interesting stuff tho. I wonder if they do something similar on the a2000 card

[@WiltshireTutorials]

Somehow forgot to reply to your response... Sorry about that! Anyway, those are some valid points for not shunt modding the A4000. As for the A2000, it does have a shunt mod and I have one in my hands. Looking to test it some time.

[@pidojaspdpaidipashdisao572]

150 USD is too expensive for this, I will just get an 8 pin header for 50 cents and a stock shroud for another 20 USD.

[@WiltshireTutorials]

Fair enough! The 8-pin header will make no difference unless you shunt mod the card to draw more power. The only benefit will be not having to use the soldered on 6-pin extension Nvidia did. The heatsink upgrade is definitely worth it!

[@noth606]

The A4000 stomps the RTX 4060. The A4000 is between a 3070Ti and 3080 after being shunt modded. Not to mention the A4000 has ECC VRAM, making it a much better choice for me for editing. The only argument that could be made is the power draw between the 2.

Just sell your RTX A4000 for $500 and buy the needed powerful RTX 4070 card from a shop for $500, all the speech in this site has no point. A card that has electric power circuitry for 140w can not be guaranteed long term at 200w.

[@WiltshireTutorials]

It's the same GPU die as a 3070 Ti, which uses WAY more power than 200W. The A4000 will be fine long term. Also, a 4070 does not fit in a SFF case with limited room... So, this video has a point to it.
