I have an EVGA GTX 660 3GB card in my system, and have had it since Jan/Feb. Back then it worked great, but now it's just wrong. Its always at the base clock when my system is idling (1045MHz), in games it never reaches the boost clock and in some games and benchmarks it underclocks itself to about 400MHz. I have no idea what the problem is; at first I assumed PrecisionX was the problem, and I uninstalled it and reinstalled it but that didn't work...
Is it a faulty card and should I contact EVGA? Any ideas what the problem is and how to fix it?
Sounds like a heat issue. Nvidia cards won't boost clock if they are running too hot, and will even underclock to maintain reasonable temperatures if needed.
That's strange, as I opened up the card a few weeks back and replaced the rubbish stock thermal paste with high quality CM stuff, unless it is a problem with those other small bits that have the rubbery things on them (yeah I know, really technical ) Also, why would that cause the GPU to run at such high clock speeds when idling?
And PrecisionX always shows a temp under 65 (I have my own custom fan curve). You may well be right but it just seems a bit odd to me.....
fyi EVGA's customer service is amazing and very willing to help
That's good to know . I may ring them up tomorrow, but I thought I'd post here first as EVGA don't have any sort of Live Support Chat service, plus some people here seem to know a lot about this sort of thing.
