AMD 7900 XTX is finally fixed YAY !!!

This reference card of the 7900xtx had vapor chamber issues in the older models, it was resolved with later models

Big Boss would be proud.

To bad crisfix is not posting more videos! Guy is a truly professional

There was an issue in the factory where too little liquid was injected in the first few batches, which was fixed after customers and reviewers found their cards overheating. The amount of liquid injected was inconsistent, so some affected cards may work in some conditions/orientations, while others won't. There really isn't anything you can do to fix that, since, AFAIK, the pressure inside is below atmospheric, so, unless you have special equipment, you wouldn't be able to reseal it. The only choices here are to RMA the card, to change the cooler to an aftermarket solution, ir to live with faulty cooling and underclock the GPU until that cooler can handle the heat

4K please. Whenever, soon. You're a master at your craft. Thank you and please keep the good stuff coming.

Red Devil XTX here. I stuck a Bykski waterblock on it and it's all OK fingers crossed (screw the warranty). The amount of heat coming off the radiator is astonishing. This does show the setup is moving heat but I'm amazed.

The solution is to contact AMD and have the card replaced. It's a known issue acknowledged by AMD and they should replace the card. The less ideal solution is to install the gpu vertically. Moving the hot card to a vertical position won't work, the card needs to be on a vertical mount position to start with. Der8auer tested this in his channel; Vertical = no issues, moved to horizontal while running = temp rises to 110c, moved back to vertical = temperature stuck to 110c. The issue is insufficient liquid inside the thermal chamber and happened to a small batch (according to AMD, hard to tell how big that small batch is) of manufactured rx 7900xtx reference cards.

Awesome that you got it fixed, and glad it wasn't something wrong with the chiplet design since Nvidia is also moving in the same direction (alongside already being used for CPUs from Intel and AMD). Unfortunate that all the board views were incorrect, and even after getting it fixed, the vapor chamber was faulty. Believe a lot of the early reference cards had that issue. I want AMD to compete in the GPU market so that not all roads lead to Nvidia. Hopefully the customer is able to get the vapor chamber replaced/fixed. Always enjoy watching your repair videos 👍

AMD always change their layout with every generation, as I remember from previous videos, Happy it did not go to waist. I was bored so went back to your oldest videos and checked if there's any that I didn't watch and liked. Your videos are therapeutic tbh with the type of music and vibes you make in them!

try each orientation when its cold. changing the orientation under load will only make it hotter. it wont cool down no matter which way you orient it once the vapor chamber fails because the water cant condense once its that warm i heard on a derbauer vid i think

Some of the first run of 7900 XTXs with vapor chambers had a manufacturing defect relating to not enough fluid in the vapor chamber. The problem would typically only show up if the graphics card was run vertically rather than horizontally (or was it the other way around). It got past QA because they weren't testing them in both orientations, I think. This should be a warranty claim for sure.

Early 7900XTXes have had issues with that vapor chamber, cooler simply needs replacing, there is now way around it, unfortunately :( Good job on the repair and not giving up no it!

If you drill into the vapor chamber, you lose the vacuum. You need special tools to pump down and seal it..

can you please link the stuff you use in the description? like solder, flux, stencils or if you already made a video with them that would be good

The hotspot problem was probably due to broken vapor chamber, plus you might need to use PTM 7950, to compensate for a potentially uneven die or contact due to bad mounting. It wouldnt be of much help if the cooler itself is the main culprit though. I repasted My Hellhound XTX with PTM 7950 and my hotspot never gets higher than <18c,usually its around ~9-12c. Unless I OC the card and make it consume 400w,or use very low fan speed (<1300rpm) the junction doesn't even exceed 80c,even during the summer, and it's already been a year since the repaste. So Powercolor are good but the stock paste pumped out in a month 😅🥲

Tony, great repair work.. at last its alive.. My friend had similar 1st gen cards, which were on fire like this one.. getting hot very fast and crashes. He had to modify and add a liquid cooling solution, after which the card is functioning perfectly with no more issues. But you know display card liquid cooling is not a cheap solution and needs adequate space in the PC case, so may not be compatible for everyone. 👍👍

Maybe get a cooler for cheap from someone who installed water cooling block on the card and see if another cooler fixes the issue. I also remember something about early models being under-filled. Not sure if drilling and filling would help, those chambers are filled under vacuum or certain pressure, so that liquid evaporates at lover temperature.

Looks like its one of those reference design cards that had the vapor chamber issue. They replace those if u send them in..

Here in Serbia, that symptom is called pump out, it can only be solved with the PTM7950 Phase Change Thermal Pad!

Solution for vapor chamber is to replace it or fix it by adding more liquid. There is a port that has been pinched already, you can open it and fill through there then attach a copper line to it to pull a vacuum through. Pinch the line while under vacuum then solder so it holds, fixed.
