Guys i have big problem ...

Today i mounted my second 570 and here we go:

1. When i plug two card like in manual - no sli
2. When i plug to 2th pcie slot and 4th pcie slot - no sli

I try with different gpu drivers, with/without sound card etc. Always the same thing: two cards are in system, but no sli, one of card has UNKNOWN bios, but when i put only one card - everything is ok. Both cards have good bios etc.

Here screen how that looks:

I had GTX580 SLI issue with Win7 X64 SP1 (Slipstreamed)
Solved by reinstalling Win7 X64 without SP1, installed GPU driver, then SP1 pack. SLI is working again.
