Hello, this is my first in this ROG forum
My system spec:
Ram G.Skill 8GB dual channel
ASUS 7970 DC2T
Mainboard P8Z68 V - Pro
Power Corsair AX 850watts
Windows 7 64 bit
I bought 7970 DC2T today so I start to overclock it. Default speed is core 1000mhz @vcore 1.050v and memory 1400 mhz
Here my problems:
Its run very perfectly at default speed but when I try to OC to 1050, I get artificial while running MSI Kombuster and crashes. I use MSI afterburner to OC it by move Core speed from 1000 to 1050 to see how its perform. Well, its just 50 mhz and its can't go any higher?
I try to raise more Vcore but I still can't get it stable at 1050 or 1100... its get artificial and crashes I even raise Vcore to 1.3v. Still no go.
I try to raise up powertune to 20% but something strange happens, my screen get flickering at default speed while testing
I try to re-install many driver but still crashes, its will run good only at default speed... :/ its strange!!! how come I can't overclock my 7970 DC2T??? I even try ASUS GPU Tweak...
I get the bad chip? :/
What should I do? if I decide to re-install Windows, its will fix it?
Thanks in advance!
