[@bigpoppa1234]

I never had dual chip but I did have sli 980ti's (I upgraded it on a whim after my PSU blew up and took my single 980 with it) and used them with a 1kW PSU. Gaming in summer was a test of how much I could tolerate the 700w worth of heat being dumped into the room. Swapping them out for a 3080 was well overdue and undervolting it basically halved my power usage & significantly lower heat load. Those days are over, same as those dual chip (I always wanted a 590 and those sli 980tis almost made up for never getting one) units. I suppose that shows just how well things have improved since then. I wouldn't mind Jensen having a crack at a 5090 dual GPU, surely with all their tricks, DLSS, frame gen etc etc their engineers can make something that can run City Skylines 2 at 30fps at 4k.

[@jamescampbell8482]

It’s really sad because they developed explicit multi GPU as part of DirectX 12, so a dual chip GPU would be worthwhile if the games supported them, and without all the micro stutter that existed with us ally in crossfire

Sort of looks like there is a missing tantalum cap on the VREG of the first die, on the top 6 VRMs, the 3rd one is missing the cap.

[@h4x0rm1k35]

I seen that too, right around the section where he says that the GPU's are exact copies but turned 90 degrees, you can see on the other GPU that all those caps are there and not missing but on that specific one on the other GPU side is, you can even see a little bit of the old solder left from where that cap got ripped off cleanly! As the card fails on 1 of the GPU's that'd be my guess as to why too. Thumbup @TA-mx3zm 's comment up people, get it to the top of the comments so that @Der8auer see's this rather than having to send it off to Chrisfix as it'll only cost a few $ then and make for a nice repair video too!

[@Vatharian]

One missing phase would certainly make it unstable.

[@michaellegg9381]

I noticed that as well. I googled pictures of the disassembled card and yes according to what I can find it's missing a cap. I actually don't think it was ripped off the card or it would have destroyed the pads it looks like it was removed and no one cleaned up the pads with the iron and copper wick.. maybe they removed that cap to disable that phase from a short preventing power on or boot up.. or the GPU chip has degraded and wasn't stable and was completely disabled by removing the cap.. that's likely caused a power on or boot issue regardless of the driver settings so the only solution was to disable that chip in hardware not by software to get the card stable enough to boot.. but i'd replace the cap to see what happens and to trouble shoot the actual problem instead of just disabling half of the card. Kinda sux selling a card as working when you know it's not and you hid the defect by removing a part to make it boot stable.. that is something the Chinese Ali express sellers would do to con people out of cash money 💰. The card is pretty good as a single GPU card and capable but I want to see it running properly.

I had the same issue with 295x2, at first thought it was second GPU at fault, but the problem was in PLX-bridge MCU (it has it's own thermal interface under the cap, and it looks like a PCM, but was dried to concrete). While I was able to get another PLX from workstation GPU of same era I managed to fit indium sheet between chip glass and its heatspreader and replaced died PLX-bridge with one I've prepared. All was fine except faulty Adrenalin drivers at this moment, so I've used Radeon PRO enterprise drivers (for WS cards), they were muuuch more stable back there (yep, they are containing drivers for gaming cards, but no Control Panel).

[@DelticEngine]

My first dual GPU card was the Powercolor 3870 X2. That card was amazing! Not only did everything get accelerated by the dual GPU being on one card but it lasted for years until a bad driver burned out the second GPU. Otherwise, it just kept on going long after other peoples cards had died. Yes, it was expensive but the performance and longevity actually made it cheaper than incremental upgrades. I would absolutely love another dual GPU card!

@@DelticEngine I ran my Diamond 4870x2 that I used to have From 2008-2019 I had to repaste it in 2014 as it filled with dust and started overheating. Part of me misses that card and wishes I had kept it as a momento rather than sending it to e-waste.

[@CyberneticArgumentCreator]

@@DelticEngine "The Radeon/AMD card was amazing until it catastrophically failed" many such cases

[@DelticEngine]

@@evileyeball Interesting you should mention keeping it as a memento as I kept mine, and the box it came in! I still have it to this day. My own experience is that I didn't have problems until I did a totally fresh driver install which lost something that had kept the card working properly. Up until that time I had been extracting the drivers and using the .inf file to update the driver. This worked great and the card stayed happy. After the completely fresh install it was like the driver didn't see the card properly and my poor card suffered and died because of the lousy driver. Ever since then I have had a distrust of AMD's ability to write drivers that work properly. At the time I wasn't experienced enough, unfortunately, and didn't know which drivers were okay and which weren't. The only thing that maybe would have worked would be to go with the driver that came with the card and incrementally update as I used to in the hope it would fix things. Other than that, I (much) later bought a 4870X2 HOT edition, which so far I've never used because the situation changed. I'm now getting familiar with Linux, Fedora 38 in my case, and watching this reading the comments has started me thinking if these old cards would work properly under Linux and maybe even play some (relatively) modern titles. The Vullkan API would likely fill in with the CPU various shortcomings in features of the rather old GPUs.

Had no idea this existed. What a unit of a GPU at the time. And I just think it's funny that two eight pins with 16ga wire is rated to 720 watts and would be way more than enough to power this if it weren't for stupidly conservative sensing specifications.

[@asm_nop]

Honestly, we could have done a 4-pin connector. Two fat lugs with thick 8awg wire, and a small twisted pair for remote-sensing. Or maybe 10awg, and the stupidly high power cards can use two.

[@fleurdewin7958]

Or use existing EPS12V connectors that normally meant to feed the CPU . That is what Nvidia uses for their enterprise cards

[@Punisher9419]

You can tell how fucked the market is now considering you could get 2 GPU's on one card for the price of a mid-high end card now. Imagien if they had two 4090's on a single PCB, it would cost like £4k+. GTX 690 was like £700 I think back when it released and I thought that was mental at the time but now that will get you a 70 series car maybe. Nice cat by the way.

[@kevinerbs2778]

You get the same wattage now as two cards in one now, (some RTX 4090 go up 600watts) & they take up four slots now too. I see no real improvement & only software gimmicks to trick you.

[@HyperMario64]

Wow, it really is a dense card. The engineers must have had a fun time designing this.

[@DigitalJedi]

Having done board design in the past, this thing is a work of art. There looks to be 32 memory ICs on that card, which is absolutely bonkers. On top of that, a pair of GPU dies, a PLX chip, and the PCIE routing to make them work together. Not to mention how you go about routing power from a gigantic monolith of 8-pins like that. I'm sure the power planes of that PCB look incredible.

[@djdoo]

If it does not miss any component it is very likely to be the multiplexer bridge chip either failing or desoldering itself. I had 2 HD 5970 cards, first one did not work at all and baked it in the oven and worked for about a month with crossfire working then died again and the second one works with crossfire but for the first run of the PC until it actually warm up it shows artifacts on screen and freezes image for seconds or even freezes the PC completely. If you restart it works perfectly both GPUs. Really weird beasts but pretty cool cards, cheers from Greece! Jim.

[@BrunoVilela1]

OK, here is something I found messing with 2 AMD cards, Re-bar and Above 4G decode must be disabled, (and yes I know if disable 4G will disable Re-bar), I've noticed on GPUz that re-bar is enabled for the second GPU. I Doubt we will see another video for this card, but I think it is good for the community to know that turning on Above 4G decode has some problems with dual GPU on windows 10 and 11 for 3d applications (don't know why yet) It run ok on machine learning, BUT i got some weird problems with PCI lanes and some stuff not working properly, like my numpad on keyboard.

Definitely glad that I talked him into buying a beefy PSU when he built his rig.

[@PianoJoe822]

Great video! And that kitty at 8 minutes 😍

[@LOLHoneybadger]

As someone that ran QuadFire with 2x R9 295x2 cards, I can say that dual GPU cards were pretty freakin' awesome back in the day. I enjoyed a 3 monitor setup with the 4 GPUs so much in the games that supported it. Seeing cards like these being looked at again is fun. Wish they'd make more, but I'm sure the money required to develop them vs the limited sales wouldn't be worth it now - I imagine it would cost a lot of money to design a 7900XT x2 GPU, and because it would likely cost upwards of $1700 I would guess, it wouldn't sell very well, especially since the support in games would be limited unless it was all driver-side Crossfire.

[@joe--cool]

Haha, yeah I still run my 2x Radeon 5870HD setup. A supported game like Dirt, Crysis, Tomb Raider or Mad Max gets almost double the framerate. Combined with Eyefinity and 3 CRTs it was amazing. Too bad no Unreal Engine games support it any longer. Most Unity3d games work when launched with "-window-mode exclusive". But scaling isn't always good. Or it runs worse.

[@robertlawrence9000]

So cool! Hopefully KrisFix will take it and hopefully find the issue. I really want to see a follow up video. Only if manufactures would make newer cards like this still.

[@dberry1973]

I had lots of fun back in the cross fire days, with my 2 x XFX R570s never had the money for a dual card! After years of gaming my 2 x 570s spent a good year in a mining and rig with other various cards and still survived today and both work!

[@lemagreengreen]

Could it be that one damaged PCIE pin causing the problems? seems unlikely but...

[@Nobe_Oddy]

I think it's VERY likely to be the prob...but there is only ONE WAY to find out lol

[@asm_nop]

The last PCIe contact pad on the back of the card is a ground line. The one next to it is part of the 16th PCIe lane. Since the first GPU performs as expected, it's unlikely that the lane is damaged or shorted, and missing one ground (of many) won't matter much. Worst case, if lane 16 was taken out, the main link should fallback to x8, but the links between the GPUs and PLX chip would be fine, and both GPUs should still work identically.

[@michaellegg9381]

It's the missing cap off the 6 phase vrm.. likely because of a degraded GPU chip and was no longer stable or something was wrong with the vrm phase

[@AlexanderVRadev]

Yeah AMD did something to the drivers few years ago. I had a R9 295x2 that worked perfectly fine and after needing to reinstall windows no driver would allow for both GPUs to work together. It happened at the first generation of cards AMD had no crossfire supported cards and abandoned the technology. Their GPUs are build so well from that and previous eras, but the software support made me swear never to use AMD GPUs again. SLI on the other hand still works fine and you can even use different GPUs no problem with that workaround that disables forced restrictions. I think it was called different SLI auto.

[@viggokallman1649]

Dude im sure theres a driver on linux that would work perfect. Don't give up on AMD yet😢

[@kevinerbs2778]

That "Different S.L.I auto" won't only works up driver 427.89 on Nvidia it doesn't work any thing past GTX series like RTX 2070 super on up to the RTX 3090 TI's which have S.L.I connectors.

[@gsuberland]

I initially thought they would just be driving the LEDs off the VRM controller's PWM outputs, but it looks like they're instead running it as some kind of bar graph, which is interesting. I can't see a multi-channel comparator package anywhere but there are exactly ten SOT23 packages on the back near the power inputs, which may well be BJTs/FETs set up to switch on sequentially depending on the Vcore line's current sense voltage. Bit of a gimmick but kinda cool for that era.

I always like these type of cards, super unique and inventive. I think the reason why SLI went dead is because you could get two 150-200 dollar cards and have them perform better than a single high end card. At least that is my understanding of it. I would love to find a card like this.

[@fractalzombie]

As I know, for now, when main load for Video Card is AI loads, it will balance loads between chips greatly than loads from standard rendering (game, video etc), and as I understand this was the main issue for this cards, sli, crossfire, two chips was very hard to make working with equal loads, but now, when AI making render (dlaa, dlss, rtx) we can check if it stabilising loads between cards. We need to test it, if this is as I say - it will get huge performance increase.

The crashing problem is due to very new driver. Since the card is no further supported, it runs in a legacy mode. Just find a driver close to the release of the card and your problem will be solved. P.S. Finding the appropriate old AMD driver is like winning the lottery 5 times in a row...

[@luminatrixfanfiction]

Yeah it's definitely a driver issue, not a hardware issue unless there's a missing cap on the pcb causing instabilities. Trying to get two gpus to work together in tandem on a single PCB would require specialy driver magic coding to get the two gpus to cooperate. AMD obviously abandoned the technology if their newer drivers are any indication. He needs to go back to the very original legacy drivers, and maybe start with version 2 or version 3 of the first driver update (amd will have implemented fixes and improvements with a few versions after the original).

Could be that the PLX chips were known to have problems in cards like this because they consumed about 30w on their own and have a paste TIM under the IHS (so 2 layer of TIM in total) instead of solder. I thought this was fixed on the newer cards ie 390's but who knows Good chance you are right about the die of card 2 being the problem. You can see when he started testing GPU#2 did get to about 30% load and the freq tried jumping up from 300 MHz. Combination of Powercolor lack of quality back then and poor lead-free soldering unable to survive the thermal cycling of these crazy hot running cards. The gpu in the front usually the problem with such a long card with seperated cooler and flimsy backplate causing a lot of flex to the pcb

I used to run a version of this card and ANOTHER 290 in triple crossfire. I had to have a second GPU dedicated to the dual GPU card. The system could pull over 750W.

[@evileyeball]

I had a Diamond HD Radeon 4870x2 and Man do I miss this card which at the time was the top of the GPU pile in 2008... Now I am running a 3060TI which is decidedly midrange. haha

[@larryrodriguez1977]

I miss sli. I used it on dirt 2 and the original borderlands with dual 970s. yes I know those cards were gimped by nvidia but they ran great for the games that I was playing.

Re: The amount of thermal paste - was it Steve (GN) that was the previous owner?

[@EinSwitzer]

Best I did required 2 as in two power supplies to assist in float to load required / it wouldn’t be able to over charge for something then pull to hard causing a power fault

[@deathfroude]

I had the old AMD Radeon R9 295X2... gave me so many problems in games, but l loved that damn thing lol

[@Rabbit_AF]

My VIA UD8 has something like that PLX chip between the 2x S3 5400EW chips. The VIA UD8 is only PCIe 2.0 x8 so.... Umm... 2 GPUs for 8 lanes. 😅 I sold off most of my S3 collection. I probably should have kept one of the earlier UD8 Revs I had because the one I still have needs a UEFI motherboard. Anyways, I didn't know with a controller like that that it can use all it's PCIE lanes.

[@psiklops71]

At 9:51 resizeable bar is disabled but when you go to gpu 2 it's enabled why is that

[@PhilippJanusch]

thats a good question, and didnt came up on the german video

[@emmabentley7945]

8:12 draw me like you draw your French cats jack 😂

[@RedEvee]

i used the Radeon HD 6990 playing battlefield bad company 2 and i do remember it using both gpus. tho not running very well because amd drivers and crossfire profiles was terrible

[@RedPolack]

There should be a modern dual gpu like 4060 x2 it will actually utilize all PCIE lanes

[@ChaosHusky]

Also a quick thought Der8auer: Try the card on a less security patched board/older version of Windows, such as 7? The PLX chip might be triggering security issues due to the 'bypassing' or the newer kernel with the older driver simply isn't stable! AMD started disabling CrossFire for me even back in the early 2010s, the first one to go was StarCraft II and FPS slowly dropped, as i said in a previous comment i ended up just using a single card and put the second one in another machine, so friends could play games then.. And all but one of my HD5870 cards died, as well as a brand new R9 290X from MSi (they also managed to crush the fans and kill the bearings by packing it too tightly in the box straight from their factory! Two weeks later, the price also halved..oh, i was pissed. Hence never using AMD for GPUs again nor CPUs since 2010)

[@mnemonic6047]

Have you tried another CPU + MOBO combination? I remember motherboard manufacturers indicating crossfire / sli support

[@Sandmansa]

I was aware of the 295 X2. But not aware of these 390 variants. That's pretty cool.

[@gregzito9395]

Can't wait to see the KrisFix video

[@primodragoneitaliano]

I really hope Kris can repair it given how this is one of those "one of its kind" GPU's ! I'll be keeping an eyeout for a follow up on this :D

[@shaneeslick]

G'day Shiek, Roman & Makita, WOW! what an AWESOME! GPU yes Power Color's Red Devil along with Sapphire's Toxic & VaporX have always been a very good looking Designs, I didn't know these 2x R9s existed, so was this the last Single Card Crossfire GPU🤔? sad it is having problems, I hope Kris can work some "Black Magic" on it.

[@Fester_]

01:15 time in 390, 390x etc.....English isn't his first language. Memorising and enthusing in a different language - respect.

[@Skotty64081]

I feel like dual GPU solutions, be it on the same card or paired cards, has always been problematic, and that's probably also why they stopped doing it.

[@jonathonrosalia9345]

Dual gpu cards are cool I’m trying to get a functional Titan Z for my collection I have a 690 right now along with a few other Titan cards but would like to get a Z and a 295x dual for my collection

[@blakegriplingph]

"We'll be having one hell of an electric bill." 🤣

[@tonyy.8852]

I think I saw this somewhere before, but damn! 4 8 pin is crazy

[@gren1977]

Can't wait for the fix! Hope that one gets a video too.

[@Gabriel_Kito]

Looking forward to see KrisFix repairing this beast and them hopefully here again with a new look on the benchmarks!

[@KMon1111IND]

So my pc was dead and I borrowed my friends laptop which has AMD APU with R5 graphicscand a discreet R7 GPU. I faced similar problem with that laptop too, the laptop will always use the built in R5 not the R7 no matter how many things I try nothing was working.

[@HD7970]

Its an issue with the plx chip. I have a titan z with the same issue where i can get 1 gpu to work but my system hard crashes whenever i try to use the second. Plx chip is absent in nvflash and even flashing it manually did nothing.

[@iszotic]

I had a 390 with the same issues you described, it barely was able to run windows and crashed under load.

[@Surms41]

As you already know and see @der8auer, everything with it's thermal design has been tampered with and not in a good way. I suspect since it's a dualgpu 600 watt card, that it may have broken traces due to heat expansion. Maybe try and remove the cooler and bake the GPU to reflow all path traces. This happened twice on my old crossfired 4870x2's, which drew about 750 watts. Both cards got heat damaged due to old paste and they both worked after reflow.

[@kepler104]

Yay! request krisfix to make a repair video if he takes it for repair.

[@siberx4]

These dual-gpu cards were always really cool, but the practical reality of living with them was not great. I had an AMD 4870x2 and while there was the occasional title where you'd get both GPUs working properly near full load, it was a lot more common that you either got nearly no scaling from the second GPU (leaving you with an expensive power-hungry 4870) or the frame pacing was bad enough that you still got a stuttering, slow experience despite your average FPS number being quite good. I'm glad they're no longer trying to market and push multi-GPU because of the difficulties both AMD and nVidia had in making it work consistently, but it always felt like a lost opportunity to me. Rendering graphics _seems_ like it should be so easy to parallelize across multiple chips, but modern pipelines are so complicated that I guess that's harder to pull off than it sounds.

[@KRAVER_]

That R9 390 was a killer card back when it was new. Devil 13 cards were Power Color's beginning. I had 2 ASUS R9 280x then 3GB each with 850HX psu. Too bad CPU's still sucked back then. or we might of gotten more out of those top cards. 2013-2015 Throwback I think it is funny 2 GPU on 1 card and still less than 3 slots. just lets you know how much faster and hotter cards have gotten.

[@ThunderingRoar]

and quieter, GPUs back then were much louder
