SLI Problems.

G'day,

I got a
AMD Phenom X4 9600+
GA-M57SLI-S4 Rev 2.0
4GB of Kingston Hyper X
Thermaltake 1,000Watt Modular PSU.
and
Dual Zotac 9800GT's
Windows 7 64BIT RC

Here's the Problem, I put them in with the SLI bridge and only one reads in the Device manager. There is no option in my Bios or Nvidia CP to enable SLI, the Bios and Drivers are up to date as they are the latest as of today. To start with I had a 650Watt Cogen and i thought well that must be the problem so i got the Thermaltake and nothing was any better, then i thought I'd check if both cards work and they do, next i checked if the motherboard was faultyi can run one car in either slots so it shows its not faulty. I have installed NTune on top of the latest drivers.

Please if anyone can find the problem please leave a post or email me at cjhurford@live.com
