Evga sr-2 classified | evga gtx 580 quad sli

Doesn't really work like that my man
GPU clocks/speed aren't the only thing that determine overall GPU score in 3dmark vantage. Even at 1100-1122/2400 in quad, the gpu score is still 75-76k on SR-2 at the system speeds I'm running, but on a gulftown at 6.5+ gt's its more like 79-80k.
My best quad speeds through the game tests with 580 so far is 1120/2400, just need to pair it up with my max system clocks for final runs. Any higher than that is pretty tough unless I go really crazy with the profiles. Next runs should be something like 76kgpu/76k cpu/76k+ overall.
As far as the gpu speeds from single to quad, they are always going to go down some especially on sr2 where there is so much going on at full speed on the motherboard. Power issues, board limitations, baseclock/ioh/nf200 stress etc. are some of the things restrict quad clocks.
Successful SR-2 vantage benching is all about finding the correct balance between components. I've learned just pushing raw clocks as hard as you can is a really bad approach and not the best way, it simply doesn't cooperate.
