Had to lower my 7900GS OC from 717Mhz to 705Mhz ???

post #1 of 4
Thread Starter 
Not sure what is going on exactly, I did the volt mod at 1.55v then Oc all the way up to 717Mhz core a few weeks ago, it was fully stable on ATI tool.

Recently I ran ATItool and the damn thing started to artifacts, I had to lower it all the way down to 705 for not artifacts.

I'm not sure if its because the ambient temperatures have gone up recently because of the warmer weather?

My MAX ATItool temps has gone up from 62c to 67c in the past few weeks. I only recently did the vcore volt mod and OC on this video card maybe 2 weeks ago.

Is this normal?

It could just be that you stressed the GPU too much as artifacts can manifest themself into the card over time.

hmmm over time? its only been about 2-3 weeks?

I lowered the speed to 700Mhz... I'll leave it there for gaming. I'll run ATItool artifact scans once in a while to make sure it doesn't get any worse. Can the higher temps be causing this?

I used to be at 62c MAX temp, but the temperature weather went up in the past few days.. "summer is starting soon" and now I'm usually around 67c MAX.
