VRAM usage in Furmark

post #1 of 17
Thread Starter 
Furmark is only using 200MB VRAM during stress testing (sig rig), is this enough for a correct stability test?

also, i am getting random system restarts after installing 320.18, i am pretty sure that this is a driver issue but could it be a PSU issue as well? cause i have my GPU oc'ed

It could be a PSU issue, but it is most likely a driver issue. The furmark vram usage would indicate drivers. What is your gpu usage during furmark?

Ok, that's about right. What are your benchmark settings? I will do the same settings and see if I can duplicate results.

I got about 20 percent memory usage. Most of which was used by background things.

so, back to the original question, is using 200MB enough to determine stability?

You are probably best off cutting back on the overclock for now, retesting, then if it doesn't work rollback and use your old overclock settings. It is a pain, but it is the only way to know for sure if they GPU is bad/not as stable as it used to be or if the driver is just not working right.

On memory overclock? No. Try OCCT memory test mode

and so i did, lower the Core/Mem clock by 50Mhz each + lowered the voltage from 1.037 to 1.025, running furmark for 5 minutes now and it seems stable but my previous OC ran it for half an hour too with no crash at all

thats why i have no clue as to what is going on
