post #1 of 5
Thread Starter 
Title and sig pretty much explain it all.

Possible causes of this? I'd like to have have some idea of the possibilities before I tear down my loop.

Help appreciated

it is supposed too, on the M4E 8x/8x for single or dual card setups is faster than with NF200, which is meant for more than 2 cards.

your mobo will read x16 with a single card as the onboard PCI controller on the sandybridge processors are only for 1 x16 lane, when you use 2 cards in SLI they automatically defect to x8/x8 for both GPUs to work correctly.

you will NOT see an performance hit unless you are running a synthetic benchmark like 3DMARK11 and it will only be like a few point and in games you will see a 0-10FPS drop from x16 to x8 but nothing noticeable
