RTX 3090 500w XOC BIOS doesn’t work?!?

[@ChamberTech]

[@Shadowdane]

Could probably even get higher clocks if you didn't throw the voltage slider to maximum. Turing & Ampere have never done well with that as they draw soo much power and start to throttle clocks kinda aggressively if your power limited. Personally I got better overclocking and benchmark scores with a 0mv offset and actually under-volting the card so the power draw always stays below the max limit. As soon as your sitting at the TDP limit in the BIOS the GPU is going to drop multiple clock speed bins to stay below the power limit.

[@chincemagnet]

Great video, subbed, looking forward to future content. Also, can you explain what happens with the multimeter if you’re not on the correct spot? You’re checking continuity? I know only the most basic function of multimeters, I have a couple, but don’t often need to use them.

I’m personally not into hardware modding as I don’t have the solder skills and tech knowledge to do it. But to see you go jank A-Team/MacGeyver with that glue gun and resistor was pure gold 🤩😂👍

[@arckie]

do you have a more in-depth video on the pci-slot shunt mod install? like where exactly did you place the shunt on the PCB, and what's the exact shunt we need to buy? do you have a link to the one you glued on there that we could buy? thanks!

Worth noting my original FTW3 Ultra 3090 fried (literally popped something on power 1) and was limited to 450. My RMA arrived (black trim) and it will max at 505w with this bios (no shunt mod) so it may be something they fixed.

[@Velmwend13]

Switch from power target to temp target, allows me to pull up to 490w+ in demanding games, if you leave it on power target it was only pulling around 460w for me.

[@tresnugget]

500w bios worked on my 3090 ftw3 no problem. I was pulling like 480w last night.

So I currently have a 3090 TUF... I have been still trying for a 3090 FTW ultra with the idea that it would take better advantage of water cooling with the XOC bios higher power limits... Hoping to avoid shunt nodding and just throwing a bios in there instead. Do you think this is just a pipe dream at this point and is shunt nodding basically the only way? Is the two pin TUF worth shunting with ASUS' horror of an rma process and water cooling?

Could you please do a video on your pc specs/settings for your 3080 for Warzone and why/how it runs so good? So many people are having issues. I have the PNY 3080 with a i7-9700k OC 5 ghz and when I'm not streaming I'm getting 160ish fps and when I'm streaming its like 110-120. Iv followed all the videos you've posted until now, but nothing seems to fix my issues. SOS please!

[@rv7768]

Great Video,,would a single pcie shunt work on the 3080 with 450w bios?

[@shabazz717]

My 8 pin #3 only pulls about half the wattage as the other 2. I got a new PSU, I’ve tried different bios. I see on EVGA forums that it’s a known issue.

Some people are getting the 500w on the non ultra version, and some are getting it on the ultra version. Jayz2cents found that there are 2 separate bios shipping with the ultra... possibly some work and some dont? Because if even one person is getting 500w with a 3090 ultra then it cant be physically constrained.. .. I hope... Love your work though an I'm definitely described.

[@FateCarver]

Thanks for the information brother

[@Stoney-Lawson]

Do you happen to have a link to where I can buy the resistor?

[@thomasowens720]

Is there a new bios where I can get more than 500W on my 3090FTW3 ultra?

[@ColinDyckes]

Sorry for the dumb question, but are you saying that you can't just shunt the multiple main power rail resistors (. 005Ohms in parallel with additional .008Ohms) and just use a standard bios? I.e. Is it overall restricted by the PCIe power draw? I appreciate that the gpu bios mod would mean just adding the PCIe shunt. Just a little concerned at drawing up to 120 Watts from the PCIe slot. M/B is Asus ROG Formula XII. I am waiting for my 3090 Strix which will have an EK Vektor waterblock. 1000W PSU with 5.1GHz all core OC 10900k.

[@angel_oscuro]

were you able to overclock?

[@ColinDyckes]

@@angel_oscuro I decided that it wasn't worth the risk of shunt modding my Aorus 3090 Xtreme (Asus Strix cancelled because of non availability) given the inflated prices of 3090s so just overclock the standard board. I do have waterblocks front and back - Bykski and MP5Works.

[@angel_oscuro]

[@chincemagnet]

You shunted modded all ur shunts? I understand there’s two for each 8 pin on this card correct?

[@arestavo]

Why are the 8 pin power plugs drawing 117W with the PCIE slot shunt vs 121 without the PCIE slot shunt? You stated that they'd draw more - not less.

[@xelnaga18]

when you shunt an input it spoofs the readings on the card. so the card is tricked into thinking its pulling less and you get incorrect numbers showing in GPU-z. As the shunter you know which type of resistor you applied and will know how much to math the current reading .... like he did in the video

[@arestavo]

@@xelnaga18 It only reads incorrect on the shunted input - in this case the PCIE slot. Original question still stands.

[@xelnaga18]

@@arestavo the card does try to Ballance the power input based on some layout in the bios. So the card is now pulling more from the slot. The bios flash only increases the draw by 50 max. Additionally... I think the new bios is still not working. He should try this shunt mod on the old bios to ensure a different result. I suspect the card is doing what all cards would do with the pcie slot shunted

[@jasonwatson9339]

The board still has a total board power limit of 500W. The card still knows if it is pulling 500W total via the other shunts on the board. Each power rail (core, memory, cache) has an individual shunt that measures current flowing over it. So with more power being pulled over PCI less is needed over 8 pins to hit 500W cap. To truly disable power limits is gonna require shunting the 8pins, (3 shunts), the pci-express (1 shunt), and potentially each of the 3 rail shunts.

[@CastIronEric]

If I flash this to my 3080 Ti, will it work

[@SamsungS-or1qf]

[@tadaschitakemori]

i was ready to open my ftw3 box today and do your mod, but i had some faith flash the ftw3 and did a burn in test with kombustor and get 485w for sure your mod work, but not all ftw3 ultra are doing this.... at least not mine lol

[@abrooksdavis]

Originally thought it was an idiot move to use glue.. but that is genius. The only difference I have done is add a "tiny" amount of liquid metal to the resistor contacts so that there is not a dry contact taking place. I mean an extremely small amount. Regretting buying a hot airgun solder station now....

[@FrameChasers]

HAHAHA atta boy, although be careful with the liquid metal because wouldn’t that give indication of tampering? The whole point of the glue is to be able to RMA Card after if you have to

[@abrooksdavis]

@@FrameChasers its such a small amount that it can be removed with zero evidence it was ever there. IPA wipe cleans everything up :D

[@FrameChasers]

@@abrooksdavis yeah I was thinking of giving LM a shit as well so it wasn’t dry, but I never actually had a problem with it being dry and applying pressure with a thermal pad. Good to know someone has had success doing it that way, I may try it in the future

[@xelnaga18]

I think your current shut is still limiting the overall because it seems the PCI-e was still hitting the limit

[@jasonwatson9339]

Its that the total board power limit is still 500W. Shunting the pci-e just lets you actually pull 500W instead of 450; you would still have to shunt the 8pin shunts if you wanted to pull more than 500.

[@chincemagnet]

DON’T DO THIS! A guy I know blew the 10A fuse on his PCI-E shunt using an 8 mOhm shunt resistor. A 15 mOhm is much safer, although it’s still unknown just how safe, if you want to order some, you can get them from Digi Key, take the part number from the top post and just replace the 8 with the number you want, 15 in this case. Although 10 or 12 may be ok for the 8 pins, apparently the 20A fuses on those are good for no more than 240w. You shouldn’t be running over 800w anyway lol. I think 550w is the limit for water cooling before you’re risking components. For whom it may concern, I did try this on mine. I glued a 8 mOhm shunt on to my PCIE shunt. It did work fine, but obviously I took it off when I heard what happened to the other guy. As a side note, getting the glue off would have been a massive PIA if I didn’t have a heat gun. Used the heat gun to loosen the glue and it came right off.

Can you give the part number, could not find with your reference. Thanks
