Hi! I've recently put together a new pc. It worked fine for 2 weeks but now I've started having problems.
Problems:
- When I play 1-2 hours or run heaven benchmark I get this: display driver stopped responding and has recovered. (2-3 second black screen, clocks drop and then everything goes back to normal and after a while same thing happens again)
- Last time I run furmark I got this: the nvidia opengl driver lost connection with the display driver due to exceeding the windows time-out limit and is unable to continue. the application must close. Error code 7.
- I also noticed that in gpu-z bus interface changed from pci-express x16 to x4. (this happened after I reseated my gpu). Gpu was already crashing before this change.
Things I've tried:
- reseated everything (gpu, cpu, memory)
- microsoft tdr fix (changed to 8 from default 2)
- nvidia control panel: prefer maximum performance (power management mode) and single display performance mode. Vsync. Physx settings from autoselect to gpu and cpu.
- using different memory slots.
- default cpu and gpu clocks
- updated bios
- updated drivers (also tried older and beta nvidia drivers)
- reinstalling windows
- 10 passes in memtest86 and 0 errors
- intelburntest max stress 20 times (passed) and x264 25 times (passed)
- downclocking memory and gpu
- installed windows updates
- power options: high performance (link state power management: off)
- adding 12mv voltage to gpu
- increasing power limit (gpu)
- checked for visible hardware faults
Gpu temps are max 74C at load and cpu about 65C (IBT max 75C).
So far the only thing that has made a difference is changing my gpu power limit to 65%. This way heaven benchmark doesn't crash but core clock runs at 1175-1200mhz (normal max boost 1241mhz) and it limits voltages to max 1.15V (default 1.2V). I tried 70% also (voltage limited to 1.175V) but it crashed after 30min or something and I noticed from sensors that at the crashing moment voltages spiked to 1.2V.
I also noticed that when running furmark at 100% power limit. It says that my core clock runs at 1215mhz but when I change powerlimit to max 111% (furmark gpu power: 90% tdp) core changes to my normal max boost clock 1241mhz and crashes after a while.
I have no idea what to do or try anymore. I don't wanna play with 60% power limit because everything is new and should be working 100%.
Any help will be appreciated.
