Quick question about this MB. I am doing a rebuild of a system using this board. On the board is a HDD style plug marked as 5V/12V. What the heck is it for? As you may know, DFI's setup guides leave a lot to the builder. I am running SLI on this system FWIW.

Looking at the picture of the motherboard as seen here where is this connector located. On this board you have both SATA and IDE connectors, in the picture the two stacked connectors on the bottom are the IDE connectors.

For what it's worth hdds and optical drives both utilize both 5V and 12V.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

After talk to DFI, that connector is additional power for the MB. They say it adds stability to the system if SLI is being used.

Now for another guestion:

After installing both XFX 6800XTs and moving the jumpers, it will not boot. The LEDs suggest it can not find the VGA. ANy clues?

The cards are 6800xt 256's w/dual DVI outputs.

I managed to get it to boot up. Whaen it did the screen only showed 1/4 of what it was. In other words, it was so large that only a 1/4 of the screen fit on my 21" flat panel. When I tried to adjust the properties it was set on something like 2080x1960 or something like that. I tried to adjust it with no effects. Then it went blank and the monitor showed no signal. I changed to a different DVI out put. Again it booted but when I tried to adjust the screen went blank. Tried 3rd DVI output, nothing. Tried 4th, nothing.

Any clues?

Anyone? This has to be a simple fix. Something I overlooked maybe?

YEs, I have the bridge and I have set the video jumpers fir SLI. I have plugged power into each card and to the 2 extra supply points on the MB. Anyone know much about the DFI board?

As I stated before, I tested both and both worked great.

Am I the only person running DFI stuff? SLI maybe?

The fix was simple as I suspected. For what ever reason, when I saved the bios settings to enable SLI, they did not save or reverted back to a defalt setting upon exit. It is corrected now and running like a champ! Now all I need is a good DVD drive, and bigger HHD and I will be set to install XP Pro. Any suggestions on a cheap, yet good, 250 gig or larger HHD? Figure I'll pick up a Lite-on or SOny DVD drive.
