R9 390X Tri-X issues

[Sukhoi]

I recently picked up a second 390X Tri-X from a friend to play with crossfire. The card made it to me visibly intact, and made it all the way through Superposition 1080p medium when I first installed it. However, upon finishing the benchmark, it stopped outputting and locked up the system to the point the only way out was to hold the power button, no response to reset. It then briefly wasn't recognized by the system, then was picked up again. The following is a list of the behaviors I have observed:

• Can sit for upwards of half an hour in the BIOS or Windows safe mode without any issues
• If it's been off for over an hour, it will last several minutes in Windows, even running Heaven (the Superposition launcher crashes it). Trixx and Afterburner tend to immediately make it lock up and stop outputting in this scenario, though fan speed changes made in Trixx apply when it starts.
• Usually crashes within 30 seconds of the lock screen in Windows. Both Windows behaviors happen with Adrenalin and Crimson drivers
• Stops outputting early in the HoloISO USB boot process
• Stopped outputting after choosing "Try out" in Ubuntu 21.10 (HoloISO is similarly old, these are just the distros I had on my ventoy drive)
• Lasted 30 seconds in 3DMark11 GT1 in crossfire with my known good 390X as the master on the Adrenalin driver, then stopped outputting like "normal" and locked up the system
• Immediately crashed with scary artifacts (attached) when I attempted Heaven crossfire on the Crimson driver
• Sometimes after ceasing output in Windows, will cause the "no GPU" POST code then be detected again after a reset.

The same windows behaviors have happened on both my primary testbench (chinesium 2011-3 board, UEFI) and a Gigabyte Z68 board (BIOS), so it's not a board or firmware incompatibility. I haven't probed the obvious voltages on the back yet but can on request, though I don't think any major rails are dropping out since it will sometimes make the PSU make load noises while not outputting. With the knowledge I've picked up from watching Buildzoid PCB breakdowns I think the issue is to do with a minor power rail.

I understand that I probably don't have the tools or knowledge to recover it myself now, and would rather have an immediate software solution if possible rather than *maybe* learning how to do SMD work and getting the appropriate tools in the future. I don't think the core or memory are at fault since it sometimes does 3D tasks. I do want to repair the card eventually because I've wanted to do matching card Crossfire/SLI since I got into technology.

Not sure if its the power rail but I can 100% say for certain that what you see on screen is result of a memory chip on the card going bad

You can buy a dead 390X off ebay as a doner card and use a reballing station or a really strong heat gun to replace the bad chip with a good chip (youtube has a ton of information on how to do it) but for the average joe. That card is toast. Its done. Its the end. It will never game again. There is no software solution available.

I don't think it's a dead memory package, the image only happened once and in Crossfire, via a known good card. If there was a dead package I don't think it would work at all

Alrighty. Best of luck on your quest young man.

Yes it will and it shows up as in your photo.

Well it's a damn shame then. At least between the 2 cards I have a complete set of good fans so the working card won't have a clicky fan.
