Low performance for GTX 460 SLI

post #1 of 16
Thread Starter 
Hi, I'm not getting the performance i've been expecting for my GTX 460 SLI. Both cards are overclocked to 900MHz core clock and 2000MHz memory clock.

This is my score with a single GTX 460: http://3dmark.com/3dm11/2828118

This is my score with SLI GTX 460: http://3dmark.com/3dm11/3070957;jsessionid=1rcopwiysqpld64kmksvaexu0

Something seems strange, I don't feel like I'm getting the full performance I should be getting.

I'm running both cards @ 8x speed and on a 2500k @ 4.8GHz
I have a Corsair TX850

Might be a silly question: Do you have the SLI bridge on?

Your PSU is more than enough for these cards so that isn't the issue.

x8 isn't the issue either, since you won't notice more than 7% decrease in performance really.

Yes, the SLI bridge is on. Although, my second gpu seems to have a different BIOS revision, I'll try to correct that right now
