Hey guys, I'm new to this forum and relatively new to building PCs. But anyways here's my issue. I just recently switched graphics cards from a Gigabyte GTX 680 to a Saphire 7970. I cleaned out all remnants of the Nvidia drivers ( or so I think). I did a pretty thorough job. I went through all the registry keys, hidden folders, etc. to delete the old Nvidia stuff. Then I installed my 7970 and installed the drivers. After all I that I was trying to do some overclocking using Saphire Trixx. I got up to 1000mhz before I started seeing weird artifacts on my screen. So my question is: Is there some sort of software related issue that may be interfering here? Or did I really reach my cards peak clock frequency already? I suspect it's software related because increasing the voltage on my card didn't seem to help get rid of the artifacting. Maybe there's something important I'm missing here that I'm hoping someone on here could shed some light on. Any help is greatly appreciated.


Here's the list my build if that'll help:

Saphire HD 7970
Intel i7 3770k 3.5ghz
Gigabyte Z77x-UD4H mobo
8GB RAM

If it's not a GHz edition card, there's probably a reason, it's the same with CPU's and other things, if it doesn't run fast or stable enough, its performance is lowered and it's sold as a lower model.

No I think you have reached the maximum overclock for that card. I would back off the overclock some to be safe. Not every chip will be able to overclock to the same degree it is just the way it is.

I do not think it is a software problem at all. Personally I would not push any overclock to the point I would have to up the voltage but that is just me.

A max overclock increase of 50mhz seems pretty bad though, I find it hard to believe that's the card's limit. I suppose it happens it though. I'd like to hear from some other people first before I come to a conclusion on this though. Thanks for the response.
