Hi

Not sure what’s going on with my 4 year old R9 390x. It crashes after 2 minutes while running Kombuster the MSI benchmark on default settings.

When it crashes the screens go black/off but the PC is still running.

Ive tried under the he below:
1. Under clocked, but still with full voltage
2. Tried new power supply
3. Installed Afterburner and applied the extra power limit to 50%
4. Tried various drivers, old and new

PC Spec:
I9-9900k
16GB Corsair ram
Corsair RM750 PSU

Guess the card could just be dead?

Thanks

How is it cooled? I would not be using kombuster to verify a suspect card. Use gpu'z load tester to confirm the card actually still runs and work your way up to a higher load, etc.

Can't see the 'load tester' in GPU'z. How do I run the test?

I submitted this: https://www.techpowerup.com/gpuz/details/hgxyb which is info about card.

Ran PassMark (3D test) and 3D Mark, both crashed to black screens (PC still running) after 1 minute.

Thanks

Thanks I’ll try GPU’z

The cooling is default 2 fans. This is the card: https://www.scan.co.uk/products/8gb...-pcie-6000mhz-gddr5-1090mhz-gpu-2816-streams-
See where it says the PCIE x16? Next to that is a question mark, click that. That will run the render test. It's a low load test so it won't hammer the card, just let ya know if its working.

Since its aircooled, the card might have degraded over time. I'd lean towards the vrms first as the culprit but obviously that's hard to tell from here.

Great thanks.

I ran the test, crashed in around 1 minute, screens went black PC stayed on.

Thanks

Given the things you have already tried I will assume the HSF is clean anf free of dust/obstructions (obvious I know but worth mentioning) Also not as obvious but worth checking is do the fans actually spin and are they hitting their required RPM when the card is under load?
I've dealt with a few MSI cards from the 'Twin Frozr' era that had fan 'degradation'. I call it degradation because they gradually slowed over time until the card became hot enough to crash. The card follows it's fan curve and the voltage was being sent but the fans were unable to achieve full RPM. New OEM fans fixed the problem in my situation(s).

To me it sounds like the card has a bad VRM or a BGA failure under the GPU ASIC.

I'd lean more towards BGA failure because it's a bad problem on large ASICs which have large temperature swings that use ROHS solders. I've repaired a few cards using lots of flux and a hot air rework station, but the chip sometimes has to be reballed, which isn't fun.

Yes all is clear of dust, and both fans spinup and fast.

I think I may have over worked the card. As you mention and others, think it's down to heat damage so to speak. the card always runs hot which I think seems to be any issue with ATI cards, or used to be.

I've actually just ordered a MSI Nivida 1660 Super :) after days of reading reviews. Seems like a good card for my budget. It runs cool and quiet!

Entirely depends on the model and generation, some ran smokin' hot and others did not. Your card has a 275W TDP, which is "smokin' hot" territory.

If you have an XFX and not FXF brand card, they have lifetime warranties on them. I sent my old R9 280x back to them about a year ago after it mysteriously died and they gave me an RX570 as a replacement.

Alternatively, you could find someone with a hot air rework station to attempt to fix your card.

Thanks.

Ah ok, that’s interesting! So I’d get like for like price wise? Shame XFX don’t produce Nvidia cards anymore!

Dam just remembered I broke the screw warranty seal on the heat sink, when I reseated it with thermal paste in an effort to fix card!

Guess XFX won’t replace card?

Also does not look like my ATI card is covered for lifetime:

XFX Radeon R 300-Series
1) 2 Year Standard. With registration of product at
www.xfxsupport.com

Plus I did not register card with them at time of purchase!

Warranty void stickers are illegal in the USA, your warranty can't be invalidated by damaging/removing it. XFX has sent me replacement HSF assemblies before and said it was OK to change without voiding the warranty.

You can always try contacting them. They have a rep here on the forum you could try messaging https://hardforum.com/members/xfxsupport.143946/

Great thanks.

I've messaged the XFX support!
