I overclocked my Asus AMD Radeon HD 7870 GPU the other day using MSI Afterburner and Unigine Heaven. It's a couple years old now and I thought I could squeeze out a little extra juice from my card to keep it running everything up to date before updating it. The overclocking process seemed fine.
I used this guide: http://www.pcgamer.com/how-to-overclock-your-graphics-card/
While cranking the clocks I was looking out for any artifacts. I put the GPU's memory clock to a full 1400mhz (max) and still saw nothing wrong. I moved on to the core clock of the GPU and managed to reach an extra 50% before I had a PC freeze. I dialed this back until the benchmark was stable again. After a lot of tweaking I thought I found my sweet spot which run stable and my GPU temp was only maxing at around 60c on a full load. Only 45c if I boosted my fans.
My games got an extra 5-8 fps out of this and run perfectly with no problem for almost all of the evening. That is when I got the problem stated in my title. "Display driver stopped responding and has recovered". I dialed back my Overclock settings and it kept happening. Eventually I reset the OC and just went back to stock settings. It kept happening but it usually only did it once per session. After that one crash it wouldn't happen again until I restarted my PC. This was usually about 5-10 minutes into a game. I have even dialed back the clocks on my GPU with no luck.
Things I have tried:
Reinstalling GPU Drivers
Reverting to old GPU Drivers
Completely dusting and cleaning my whole PC
Boosting my GPU's power and fan speed.
TdrDelay RegEdit
PC Specs:
CPU: Intel Core i7 4770K (Noctua NH-U12S CPU Fan)
MOBO: Asus Z87-PRO
GPU: Asus HD 7870 AMD Radeon DirectCU II
RAM: 32gb Corsair CMZ16GX3M2A1866C10 Vengeance DDR3 @ 1866OC
HDD: Seagate ST2000DM001 2TB
SSD: Samsung 840 EVO 250GB
PSU: Corsair Builder Series CXM 750W
Thank in advance for any other solutions!
Is my GPU fried?
