Hi all, about 3 months ago I swapped my HIS 5870 out for an EVGA GTX480, and I dropped my overclock to 4.0Ghz. I didn't save my settings as I had to do a fresh W7 install. Does anyone have any really stable 4.2-4.5 overclock settings that I can use? I have looked around but wanted to gather most of the resources in one place for future reference. Thanks in advance.

No one can give exact settings as every computer is different. The i7's are really easy to OC. It took me 10 minutes to do mine, then stability tests. What mobo do you have? Most X58 mobos save the BIOS settings in profiles.Also, why did you have to reinstall windows for a graphics card change?

I have the Asus P6X58D- premium mobo. I was unable to get a stable overclock with the 5870 even with a mild overclock. Checked everything before I replaced it, including RAM, and other hardware. Next to last step was installing W7, and after that didn't work I found out it was the 5870. I am aware that all PCs are different, but wanted to see some settings from other users as I do not want to fry my $1k processor. I have looked at a few different sites but wanted to see what everyone here was doing before I started my last tweak of my system. Any help would be appreciated.
