Hey mate - Just thought now you have your GTX 690 running nice and cool you might want to overclock it a little bit and squeeze another 15 - 20 frames out of it , If you think you don't need to and your happy with everything then just ignore this little bit of info.
Download EVGA Precision 4.0.1 (the latest)and install.
Once app is running you will see
Power Target (set to 135%)
GPU Clock Offset (set to 120mhz)
Mem Clock Offset (set to 200mhz)
That's it this isn't an intense overclock but it worked very nice when I had 1 stock fan cooled GTX 690
and because it's EVGA precision there is no need to worry about damage to the card because it will just turn off PC
Have a look at this
skip forward to 26mins for Precision - Enjoy
damn man thats super simple and clean hows the temps as far as like furmark and 3dmarks. like i said i thought about this unit before but didnt see it working well
Will have to wait - $1100 GTX690 plus $350 for 1200W PSU, I don't have that cash lying around..
I will have to eat rice and tomato sauce for the rest of my life!
