With a GTX 780? Hot damn. What model are you running? I dropped the voltages back down to default and Heaven 4.0 ran perfect at 200/200 in EVGA Precision X. I guess I had the voltages needlessly raised.
Any suggestions on what I might try to take it as far as you?
I run a reference design GTX 780 from Gigabyte, stock clock i believe are 901Mhz Core, 3000Mhz Memory.
What you will find though, is that as you crank up the voltage and clocks together you will start hitting the 115% power limit. So use an OSD like MSI Afterburner to monitor your clocks in Heaven benchmark. When you hit the power/temp limit you will see the clocks drop, thats why the last bit of performance can only be unlocked with the bios mod to remove (greatly increase) the power limit. Also while benching stick the fan to a locked percentage were it wont hit the temperature limit.
If you can run +200/200 like me, then just keep pushing the clocks up with voltage at maximum, keep an eye on the temps, try not to exceed 85c and check the clocks to see if they are downclocking as you hit the power limit. Im sure you can get a lot more out of your card than mine, as mine is pretty average.
I found memory can be pushed up to 3500Mhz (+500Mhz) without too much issue. At 1.21v on Valley bench i can run 1230/3520Mhz. Thats not stable at all in any games however.
As i said for games, i run 1100/3200, no issues. There's not much tweaking to do with overclocking GPUs to extract more, just keep experimenting with clocks. Youll find that the Unigene benches like Memory > Core clocks.
1231 isn't a possibility on a 780. Only goes by my increments of 13mhz. Alotta people don't get this and it saves alot of time. You are either at 1241 or 1228
Yeah i know, but i dont really bother with the rounding lol.
