Asus GPU TWEAK

(Old news for Neuromancer)
I had occasion to install (2) Asus GTX680-DC2-4G5 cards yesterday. SLI was not functioning so I went thru the normal SLI troubleshooting workarounds to no avail. Checked if vga bios matched on both cards and they did. I thought maybe it was a temperature issue so instead of installing the normal rivatuner/afterburner stuff I tried the GPU TWEAK utility from Asus powered by Techpowerup.
Turns out this utility has a bios update feature
. I know, I know, windows software bios update
The out of the box version of GPU Tweak is buggy and slow. The vga bios update function also doesnt work on this version.
Downloaded the updated version and rolled the dice. Bingo, it worked flawlessly and now SLI functions properly. The newer version is still slow responding but better than earlier revisions but mostly functional.
