GTX660 unable to read BIOS flash in GPUZ

Whenever I click save BIOS to file in GPUZ, I get a Windows message that nvflash.exe has crashed, and then it tells me that that BIOS reading is not available on my device. Same problem for both cards. So how do I read the BIOS so I can upload it in Kepelar Tweaker?

Try saving it from a command prompt...

nvflash --save <filename>

You can download the latest version of NVFlash from here...

That program does not work. Any key I press in the program just advances the screen. After the screen advances five times, the program closes. It doesent appear to actually be a real program as I cant enter anything in it.

It's the same program that's integrated into GPU-Z, but instead needs to be run from an administrative command prompt.

Okay, I got a copy of my BIOS loaded up into Kepler BIOS Tweaker. However, there are a whoooole lot of settings in there, and I am not sure which ones to change. I noticed some of the settings do not reflect stock settings, even though I set my GPU to all stock settings when I saved the BIOS. Are the settings already optimized by default, or do I need to change them? I am not exactly what boxes to modify to increase the power target. The program doesent really come with instructions....
