I just buy my new config :
AMD Phenom 9950 Black Edition
MSI K9N2 Diamond Board
2x1GB Kingston DDR 1066 ram
2x 9800GTX Video cards
600 watt Silver Power - SP-600AC2 Powersupply
Vista 32 bit
I am not able to properly activate the hybrid sli.
I install the latest bios 2.1 of the motherboard and last drivers: nForce driver version 18.11, and driver gpu GeForce Release 177.79.
In the menu Hybrid Power there are three modes: "Save power", "Boost performance" and "additional displays."
At the windows start, I was in "Boost performance", I selected "Save power", the two graphics cards 9800 normally shut down.
Then I wanted to restart the 9800gtx by selecting "Boost performance", but nothing happened, the system remained at "Save power" after waiting a minute. Even after reboot the computer.
Is it normal ? bios update ?
Thanks for yours answers.
