Unlocking the Secrets: AMD RX 7900 XTX Repair after Liquid Damage 

it;'s not even that the task are so hard (though they are) it's the shear scope of all the super microscopic components on a video card . there are jsut so many and if even one is faulty the card will not work.

What I really like about Sapphire is that even their relatively cheap "Pulse" branded cards are still very good quality. Nothing too fancy usually, but very good, especially relative to the price.

funny you say this. i've had three video cards , in 25+ years of building my PC's fail on me, Two were Sapphire. (the other was nvidia brand i can't even remeber the brand of because they are no longer around). that said the longest running GPU i've had is also a sapphire (radeon 5770 HD , which still works to this day).

Have a Pulse card (Vega56) myself since 4 1/4 years. The plastic shroud is a little sharp along the edges, the cooling fins a little skewed and the fans are more noisy on some RPMs than others. But it is very sturdy, the backplate is open over the GPU and the cooling fins, it came with 3 years of warranty and the fans are plugged in like an M.2 drive for easy cleaning of the cooler and replacement of fans. Among the competition it was the balanced card. Not the fastest, not the cheapest, but reasonably cool and quiet with it's full length cooler on a half-length circuit board. Would buy again.

Sapphire used to design the Reference PCBs for Radeon cards. The parent company of Sapphire brand (PCPartner) has been working closely with AMD for well over a decade, they were even responsible for assembling the interposer->GPU&HBMs dies for Fury and Vega chips.

Sapphire is the best AMD partner and makes top quality GPU's, something like EVGA for Nvidia if not even better.

Powercolor put them on their red devil 6800xt, at least on mine they did.

It is counter measures against guarantee return scam. Scammer take a thin copper wire, put it under memory chip and fried it with 10V. Gpu and memory dead, money return. Due to miners and dishonest private resellers, this has become such a huge problem that shops often refuse warranty service to honest users of video cards.

@@---777--- That doesn't make any sense since the glue is only applied to the chips closest to the PCI-e slot. If what you said is true then they'd glue all of them on every side.

@@---777--- people should buy a gpu from legit sellers not by some nonamed sellers.. It is nomal that warranty do not live anymore.. because it was used by minners and u want cheapest gpu option.

Word!

Es ist nie zu spät, damit anzufangen

Only reason I'd shy away from liquid cooling is if the default cooler is already cooler than the liquid cooler, in terms of coolness and not cooling ability. Sapphire's nitro+ looks pretty cool and probably does well cooling the card, so I find no reason to liquid cool an already cool card, both cool and cool. You feel?

@@Kimtron142 I think this card had water dip on it from a cpu block rather than the GPU water block itself. Also, water cooling a GPU with 300W or more energy consumption makes sens. I had both Sapphire Nitro+ and now own a Sapphire Toxic Extreme Liquid Cooled (both 6900XT) and let me tell you, you can't hear the liquid cooled one while gaming. In the same case the Nitro+ was not that hot but definitely louder while also cookie the SSD's and other nearby components. Now the Toxic has the Radiator at the top of the case pushing the warm air straight out of the case so now the CPU and all the nearby components are cooler as well. Of course the Toxic is much more expensive normally but I had a "unlucky happy" case when my Nitro+ fans failed and they couldn't fix it within 14 days so they game me the money back that I initially paid (about 1400 euros) and the Toxic dropped down in price to about 890 Euros. So I got a better GPU for less money. The 7900 XTX was just launched but the price for that one was about 1600 Euros and I didn't feel like the performance and noise was worth it (as the 7900 XTX were only air cooled at the time, not sure if water cooled ones came out by now).

​@alexandruilea915 ek had water blocks day one I belive for 7900xtx. The issue is most cards he fixes are air cooled ....they are so big they break the pcb. Cracked pcb has killed more 4090 already than liquid will in its whole lifespan

@@mddunlap03 when I said that there are no liquid cooled rx 7900 xtx I meant AIO GPUs like my Sapphire Toxic Extreme 6900 xt

I share the same feelings, for me the air cooler do not spill liquid, do not break that fast, do not break the pump without you notice and we can use AC without drying the AIO's. Sure liquid is better for cooling relative to the size, but if cooling is the problem get a bigger cooler, get more fans, hell even add a table fan directly to the case of the computer, all of this is way better and the only problem is that you have to clean you computer from time to time because of dust. The liquid cooler have more maintenance, are more risky and cost more (more expensive overall, in time and price).

Same you have to reprogram the IR35217 with the correct firmware

Always updating my collection

Yes

Nah, they all forgot about it during the design phase

Asus MSI

@boofygoofy3758 thank you very much.

​@@KrisFixGermanyAny brands for amd cards you prefer or Are those the same ? My msi 3060ti died within warrenty, so i swapped it for an amd xfx card, since i had a buncha xfx amd cards back in the hd4000/5000 days without Any problem. But my new xfx cards hotspot temp worries me a bit.

@@AdaaDKbest brand for amd is sapphire, xfx and powercolor are 50/50 in terms of how good their products are. Then asrock after Although asrock are still relatively new to making gpus, I think their 6k series of cards should mainly be avoided for sapphire / powercolor, their 7k cards are good for the most part though Asus and msi Radeon cards are always 50/50 in terms of quality since they usually just use reference pcbs and they just sometimes try to use the same cooler they use for nvidia cards for amd which can lead to worse cooling, not always the case but was for a bit.

Just put a polarizing filter on your ring light

No, i don’t. No need If you have quality microscope

Maybe on day 1. Cooling water doesn't stay perfectly clean forever.

Respectively megaohms on the core clock

but please do not get used yourself to pressing the chip in the middle when you soldering it, sometimes it gonna break the bonding thread inside.

You can send it for repair. Check our website in the video description

@@KrisFixGermany thank you kris

cracked pcie near the lock area.. never ship pc w gpu in pcie!!

@@LeadFarmer813 oh that's a shame :( is that repairable or should I just buy a new one?

​​It depends how mutch is the damage but cris can fix it i believe. Send it to him and watch the video 😅

GDDR6X uses different signalling and I have seen no indication the GPU of the 7900XTX has support for it so it would actually stop working.

@@eelke29 I kind of figured. It was just a wild thought.

Different pin connection, signalling and tracing plus needs reprogrammed/new controller :D

Yes. The PCIe spec provides up to 75 watt of power for x16 cards. The main 12 V power supply for the PCIe slot is pins B2, B3 (side B) and pins A2, A3 (side A).

Coil whine is normal, especially on overclocked GPU's ... reset your clockspeeds, you might even try undervolting it just a little bit. It's not something that is in general fixable.

​@eidodk I wouldn't say coil whine is normal. If anyone gets a bad unit they should send it back. I went through a few 4090s but have a perfect one now.

@@hostile_1866 See That's the thing. Coil whine does not mean the unit is bad, it just means that the electricity you feed into the component vibrates the coils in a frequency that makes the component emit a sound. Coil whine from the GPU can be caused by the GPU, it can be caused by the PSU, or it can be caused by the cable and monitor you have connected to the GPU. The easiest way to not fix, but possibly remedy it, can be a slight undervolt or infact also a slight OVERvolt, just to clip the frequency that makes it whine. If you RMA'ed graphics cards for coil whine alone, you have been lucky, since almost no manufacturers accept coil whine alone as a failed unit.

@@eidodk Hi. We have really good consumer rights in the UK. Sure a graphics card with coil whine isn't technically faulty in operation terms, but who wants to hear a loud buzzing when they are playing games? My pc is in a home cinema with Dolvy Atmos Surround sound. I want to like and appreciate quiet scenes in my cinematic games not feel like I'm at a factory. Coil whine with 40 series in particular is due to varying inductors manufacturers use. Ironically the cheaper 50a ones are less prone to whine than the 70a more expensive ones. PSU wise I know people that have been though 7+ and its made no difference also they have tried using a UPS to no effect. Now I have a silent 4090 Rog Strix into a silent PC build and I can't tell you how much more that's worth than a unit that constantly buzzes in my living room :). Since launch both MSI and ASUS have made internal revisions to reduce the effect, as I imagine the amount of units going back to retailers was crazy.

@@hostile_1866 That just costs the vendor you have bought the card from more. The manufacturer won't accept coil whine as RMA. To an effect, that just increases the price your pc vender has to charge for the cards.

Good choice

@@KrisFixGermany it is good card, vr not best but oh well 😅

He sped up the solder work @5:30 - and I'm assuming he didn't want to extensively cover the flashing because it's really easy for someone to take a fragment of knowledge and really mess things up if they don't know what theyre doing. Like do a moar volts mod and burn stuff beyond repair. If you're interested in this kind of content you've seen soldering and flashing 1000x before and aren't too salty about what's skipped. He has a day job and I'm guessing he wants to make money not have to spend even more time editing yt videos almost for free
