They are all locked by BIOS, you have to unlock then flash.

I am getting my 2nd gtx 660 soon and how do I unlock voltage?
My first card was already unlocked by original owner, so not sure what I am missing here.

I see 7 to 10 C difference between a pair of Asus GTX 660's @ power target 110%/stock volts. That's 100% fan in a case w/ a single 1200 RPM SFLEX and a 150+ watt power sucking i5 760. Temps on the GPU's top out @ 62 and 52 C in BF3 w/ vsync off, so it's really a moot issue. Sucks for the dude getting owned by all that heat directed from a single opening, lol!

I know it will vary by the game you play, but games like BF3 will give you 90-100% GPU usage on both GPUs.
I had 2 8800GT's on Crysis release day and it soured me for years. I'm seeing exactly as you posted for SLI usage in BF3. I also do not notice any of this microstuttering FWIW. I run w/ adaptive vsync now and see much lower usage and power. The mouse lag is either minimal to the point I don't notice/bother me or it's not there. Game is uber smooth on 2 660's IMO.

Trackmania stadium is poop w/ SLI, but a single 660 is more than enough to drive that game.

So would I, but I'm afraid to flash as I've killed a GPU doing this before (and I followed directions perfectly).
post #1189 of 6755
I just OC my Dell U2913WM to 75Hz and now I'm ready to OC these 660s further. However, I do have some concerns:

1. Is it safe to run at 1.21v? Does it affect longevity significantly? Is the warranty still applied?
2. I've never flashed or unlocked a GPU before. Does anyone have a short step-by-step instruction guide?
3. Do you prefer KGB tool or Keplerbiostweaker and why?

Btw, here they are.
