GTS 250's in SLI, 1 x16 / 1 x8 Performance?

post #1 of 7
Thread Starter 
I really want to move one of my two GTS 250's down a slot to improve airflow for the top card. They're running OC'd @ 770/1890/1130 @ 16x/16x. If I were to move one card down to the 8x slot and leave the other at the 16x slot running at 16x/8x, will I see a performance decrease?

No, you won't see a performance loss with GTS250's at 8x on a PCIe 2.0 slot. You're good to go.

You won't notice it just playing a game, you might if you are watching your FPS count the whole time.

Not even then. There was like 1-3 FPS difference on GTX480's by dropping them to an 8x slot. A GTS 250 won't be affected at all.

Still not very noticeable.

What is noticeable is your temp going down..

I highly recommend u do it. leave an open slot will help immensely with cooling for the top card. also the performance is not noticeable, and hard to measure even.

oh, and try bumping the shader to 1944 and the memory to 1200
