How do you overclock dual video cards (read: not SLI)in Vista 64?

[SirFelixCat]

The only reason I want to try to do so is due to my problem listed Here.

I have D/L'd nTune and it appears that only my 8800GT shows up as available to clock, not my secondary video card (7900GT) which is the one I want to OC to fix the problem it has w/ Aero in Vista.

I have ZERO idea on how to flash the BIOS on a video card, so if anyone can tell me how to either find an easier way to OC the secondary video card in my rig or flash the video card BIOS (only the 7900GT one), I would greatly appreciate it. I should add in here that NorBiTor doesn't work on Vista 64...something about a "Can't start driver: 1275" error w/ it. So there goes that way to flash the BIOS...


Because my only other course of action is to sell my 7900GT and buy a 8600GT for my 2nd and 3rd monitor. But everything I'm reading is that the 8600GT is an inferior card other than being Dx10 and GDDR3 vs GDDR2 of the 7900GT.

Help?

I don't understand how oc'ing a 7900GT will help you

Vista 3D effects run fine on a 9800 pro at 2d clocks, so even a 2d clocked 7900GT should be vastly more than adequate...

Apparently it's an issue w/ the 7900GT and 7950 cards:

Read the last post there And no prob...


So, the easiest fix is to order a new 8600GT and when it gets here, turn around and sell the 7900GT I guess *sigh*.

Apparently, the OP means underclocking will fix the problem.

EDIT #2:

Nope, some people did report that overclocking fixed their problems. :Q

EDIT #1:

To the OP:

1. Can you RMA the card?
2. If not, can you NorBiTor with driver signing requirement disabled?

Excerpt from the softpedia.com article
However, the solutions presented by Kaspersky to disable Mandatory Kernel Mode and Driver Signing fail to deliver streamlined usage. And there is a simpler war. All you have to do is type "cmd" in the Search Box included in the Vista Start menu. Next, press Ctrl + Shift + Enter to open a command prompt window with elevated privileges. Now enter bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS in order to disable Driver Signing and reboot.
