Please list all your hardware, both in and out of the computer.
Please list all your hardware, both in and out of the computer.

My Opinion is no more important or right than yours. But if your using the LATEST drivers, go back to the prior set.

Piss Poor tech support blame all issues on drivers and assumes that your an idiot. Find a set that you know worked and see if the problem exists still.

""Don't f with it if it ain't broken!""

Constantly updating drivers is a good way to F'up the whole system.

I would remove the Soundcard and the Modem card. and all but 1 stick of RAM during this.
Both GPUs are being run by the same PSU correct?

The video cards draw their power from the motherboard. they do not have an external power connection.
The sound has been removed with the same effect.
I will try it with 1 stick of ram and the network cable unplugged.

I have an XFX 750a. Did you move the jumpers for SLI from 1-2 to 2-3 on the second PCI-E. Once done, you need to go into the bios, enable SLI. Make sure to have the DVI cable on the main card. My XFX just died on me anyway.

Heheh...

Replacement worked Flawlessly, I assume.


Other than the issue, what do you think of the two different boards?

XFX 750a is not user friendly. You need to know what you are doing. Plus mine died after maybe a year of service. I would not buy it again. I replaced it by a basic gigabyte, which worked right out of the box.

The 750a worked fine and seemed like A good board for OCing as long as you don't want to run SLI. The other problem is it was not the right board for my processor. Contrary to the fry's salesman's opinion. But having it in my case, I felt obligated to try and make it work. A week later with no support help, it was time to move on.

The new board set up was painless. Running xfx8600gt's in SLI and Raid0 processor is Athlon dual core 7750 black edition. 3dmark06 @ 8450 before tweaks I'll spend the next week tweaking it to see how high it'll benchmark
