What OC does a 570 require to produce stock 580 performance?

post #1 of 4
Thread Starter 
Hello guys, i believe the title says it all. A concern i have is these things blowing up when you overclock them.

Mine is a reference MSI GTX570 and only has 4 Vrm's so i'm hoping the result if manageable. I'm currently running it at 800Mhz/2000Mhz (core/mem) with 0.988v and its stable and safe at that. SO just wondering what clocks are required to achieve 580 level performance.

I did some 3DMark 11 comparison runs myself at stock @797Mhz core and with others it took a GTX 570 @890Mhz core to reach same 'graphics' level score within very close range of each other anway. Not combined with CPU because our CPU's varied but just 'graphics' score.

What OC 570 settings is close to a stock 580?

EVGA GTX 580 SC Stock @797 Core = 6187
570 OC @890 = 6209 and equals the performance of a stock 580.


That thread will show the progression of how we got to that point. Have fun bud

Not really fair since you are running a factory overclocked 580.

From my testing, it only takes around ~855mhz core on the 570 to equal to a stock 772Mhz 580.

True. The difference between stock EVGA GTX 580 and the SC version is only 3% though. Marginal difference for $20 more.

Only reason I went SC is EVGA bins their SC VRAM to warranty the slight OC for themselves, on EVGA per EVGA forum moderator post.

Not all their VRAM is binned so even a vanilla card can have the same qaulity VRAM and over clock just as well. I just wanted to give myself a little bit more assurance.
