Hello all,
I have a Sapphire Radeon RX 570 Pulse ITX 4GB (single fan) which has recently developed an issue.
Most times when I boot up it will be totally dead.
Its fan don't spin and I see nothing but a black screen, but the system does post and windows boots.
I can confirm this via RDP, and can see that the GPU is not listed in device manager (not even as unknown), or detected by GPU-Z.
Interestingly, without changing anything, the card sometimes just works again after some time powered down.
I've noted that when it's up and running fine I can reboot as many times as I like and it continues working,
but if I shut down and start up again, even immediately, the card will be dead the vast majority of times.
When it does work it works 100% perfectly. No glitches or artefacts, low temperatures.
I've let benchmarks run and played games - Just perfect.
I feel I've ruled out multiple things.
It's not overheating - It's very clean and runs cool.
It's not the power cable to the GPU, or power supply - All confirmed working fine with other more taxing cards.
It's nothing to do with the rest of the system - Issue is reproducible on two other computers.
It's not as simple as "only works when it's cold" or "only works when it's warmed up" - it's not that consistent.
It doesn't seem to be related to bending/warping/pressure being applied, so I'm ruling out dodgy BGA joints.
I can't see anything physically wrong on the card, like a burned component or bulging/leaky cap,
although I appreciate that many component level issues won't be visible.
I considered self-healing fuses but, then, sometimes it took days before it came back to life and other times just minutes.
I don't even know if it has those.
Today I've determined that any time the card fails I can revive it 9 times out of 10 by removing it from the machine and handling it.
Any time I took it out to check fuses or probe anything it would just work the next time.
Over time I realised that simply touching the solder joints on the back of the card (ESD safety FTW) usually results it in working the next time.
Could that suggest that something is holding charge and shouldn't be?
I'm manually grounding/draining something?
Given that it's just not detected at all when the issue is present, I'm guessing that means it's something relating to, or affecting, the bios?
That made me think maybe there's faulty cap to ground on the 3.3v, possibly, but that's really as far as my best guessing goes.
I'd be very grateful to hear any thoughts on it!
Thanks for reading, if you got this far.
