Well I'm back again with the new board (RMA'd the other) and everythng is running fine except the graphics.

Basically the problem(s) I'm having are:

1. When I run the 2 8800GT's in SLi I was getting something about not enough power and it lowering the preformance. And Vista 64bit is showing the graphics score as 3.4. And yet I never had this issue on my ASUS P5N32-E SLi Plus board.

2. I took out one of the cards in hope that it would solve the issue but it didn't. I'm still getting that 3.4 rating and freezing when I test the graphics.

I've had the same setup running with an ASUS P5N32-E SLi Plus and I didn't have any problems with the hardware so I can narrow out any faulty hardware.

I've been reading that some PSU's have problems with the 8800GT's?

And I'm also wondering if it could be the voltages that need to be changed?

Specs:

Intel Q6600 @ stock
XFX 680i
OCZ Reaper DDR2 OCZ2RPR8001G
2x 320gb Seagate HDD's
2x Leadtek 8800GT's
Antec Truepower 850W

Any help would be appreciated.

Edit: Added screenshot for the voltages.

As for the score try this:

In regards to the low power warning, are you able to test these cards with another PSU by chance? I would imagine it real rare for both of the video cards to have the same issue.

I can test it but the other PSU is (I think) only a 650W, would that be enough?

I say get a 750w.

Also, Vista score means nothing. It is just a random number Microsoft has. Just because it is lower doesn't mean your PC is slower.

I would agree with that but last time I had the same problem so I ran 3Dmark06 and I was getting 3fps on the first test. It's like it gave me a heads up something wasn't right.

Anyway update: I've just chucked in my 2 Inno3D 8800GTS's and the score has risen to 5.9 so I'm going to settle with that until I can chuck out for a 1000W PSU unless there's a way of running 2 PSU's.

Eg. Have the 650W powering the board and everything but have the 850W powering the graphics.
