- Memory timings. The fact that you're running your RAM underclocked makes me think it could be unstable.
- Power Supply, either using a crappy one or one that can't supply enough power. Looking at the specs of your "Novatech powerstation black edition 750W," it could fall into both of these categories. I've never heard of NovaTech. That doesn't mean they're bad, it would just be nice to know the OEM. Four +12V rails at 18A each is a bit weak for a 7970 in a loaded system, especially if it turns out the PSU is from a bad OEM.
- Crappy drivers.
- User error.
There's really no way to nail down the exact cause without testing the card in another system, which has been mentioned countless times in this thread.
It would greatly help us if you could do two things:
1) Fill out your system specs in the User CP.
2) Stop being so combative and open your mind a bit. We're here to help, but it's impossible if you won't listen to what we're trying to tell you.
I'll be keeping an eye on this thread.
Oh, and welcome to TPU.  |
It's the GHz Edition, at stock.
Here are some specs for the PSU, I don't really know what they mean but I hope they can help

Novatech is the websites own make, i've bought from them before and they've been pretty reliable. During furmark tests it was able to run the graphics card at 100% without any artifacts, they only occur when more than two applications are running at once even though the card only needs to run at like 30% to do so, I assume if it were a power issue then the artifacts would increase when the graphics card needs more power as apposed to what's happening to me now?
Oops, i didn't notice I had to set "show system spec" to yes, doh! Also i'm unsure as to what i've been combative about or what i've not listened to? The only thing people have recommended that i've not tried is trying my gfx card in a different machine, but i've given my reason as to why i've yet to try this and that I will asap and simply asked until then if there is anything else I can try that I haven't already.
