Edit 2: Hope the hand's ok.
You have to post the bios here I mod em then you use index= commands to flash the bios to the correct card.

I tried those two bioses you modded for me, but at stock clock, the result was the same as with kgb modded ones, unstabe in Valley, but i had to downclock this one only by 50MHz from stock to make it work. At higher clocks it was unstable even with 1.212V and the result in Valley was almost identical to the one with stock bios and speeds. I dont know if i am doing something wrong, or is it just that the windforce cards are not that good for overclocking, because they are already clocked somewhat above average. Boost clock of 1100MHz.

I think that i will leave it as it is for now and come back to it, when i will have my watercooling finished.

Anyway, thanks for your help and for the help you are providing to the community.

OK so my GPUs can get up to 1212mv but I can't seem to even get through heaven with no overclock with fans at 100%. Whats going on?



Edit: The lowest my MHz will go in Precision X is 2000... that's too high right?

You have to zip the bios files and then use the paperclip in the editor to upload the bios.

Watercooling can help a lot as it decreases the amount of voltage being leaked and can help your card perform a lot better. The Gigabyte brand of 660's (I had one before) are oc'ed too high and can have that effect of needing more power and voltage. Only needing to downclock 50MHz is definitely a improvement and if the windforce cards had beefier components They would be beasty oc'ers. Before you stop though I would like you to Reinstall the latest Nvidia drivers WHQL release using the custom installs clean install option.

IYour bios weren't modded yet were they? You need a power increase before you can run 1.212v and be stable.

Ok I think I got this figured out now. I had to install 7-Zip first.

Here: 660.zip 55k .zip file

Edit: I took a look at someone else's zip and it looks like I have to mod each bios for my cards? I will try that.

yes if you have more than 1 card I will need the bios for each card. resubmit the bios with both bios and be sure to tag which card is which.

Well I think I have it figured out. I ran the hair demo and both cards are now running at 1212mv. You did mention something about having it be stable though. Whats that about?

The thing is you have the voltage but not the power to support it.
