Fffffff*CK OKAY so basically I dun goof'd...
I'm running an MSI R9 390 on an (until yesterday) RM 550 from Corsair. Now obviously this is a little tight, and the RM series aren't known for being robust to begin with (CrapXon and all that), so I turned down the power target and voltage (as well as clocks to maintain stability) on my GPU to keep the system chugging until I could afford something better. So when I upgraded to an RM 750X I turned everything back up to normal. Unfortunately in my excitement I accidentally set the core voltage to +40 instead of +0. I realised this only a split second too late, right as I pressed the Accept button in afterburner, and was greeted with a black screen and an ominous buzzing noise. The PC will now only boot and function properly in Safe Mode on the 390, or normally on my iGPU. I tried both uninstalling Afterburner and disabling OC on startup from both these states - no luck. I can still only get to the logon screen before witnessing a glorious light show of rainbow colours followed by no light at all. I'm convinced the card is fried, and have already begun the RMA process, but I have my doubts for 2 reasons:
1. Why can the card still display an image during early boot up and in Safe Mode? If it was fried would this still be the case? Is it perhaps a catastrophic driver failure?
2. Surely only 40mV isn't enough to damage anything but the worst victims of the silicon lottery?
I haven't sent it off yet, so any help would be appreciated.
