I am at wits end with Asus Extreme 7800GT Dual..

[[=RDR=] RadoN]

I've got a problem with my Asus Extreme N7800GT Dual. It works fine running in single GPU mode, but when I turn on SLI, I can play BF2 for about 10-15 mins before my screen goes black, and I hear the last sounds in game looping, followed by high pitched beeps.. Usually it keeps doing this until I shut it down, but occasionally it will reboot itself. It will also crash like this when I blow up C4 in my face, or get directly hit with artillery.

In single GPU mode I can play all day, and it works perfectly. But when I enable SLI it gives me a 40fps gain, and greatly smoothes everything out with the extra 256mb of ram. I constantly watch temps, and the GPU's never gets above 65c so it should not be related to heat. I water cool my CPU, so it stays under 40c wile playing, and the Mobo is usually 45c wile playing.

I constantly use the ASUS SmartDoctor program, so I can monitor temps, and power wile I am playing. It is worth noting that when I start BF2, the Vcore goes to 1.52v, where it gives me a message like "VGA chipset is not supplied with stabilized voltage. Please contact ASUS for help." whatever that means. I am using the supplied AC adapter with it which plugs into the wall, and goes into the GPU through the back, so it should not be a power issue.

As I've said, I am at my wits end with it. I've updated my BIOS [v1011], also the Chipset [v6.70], and lastly the Graphics [v82.12]. All my system specs are listed below, I should also mention that BF2 is the only game that this happens with, all others [Quake 4, CS: Source, Half-Life 2] work fine! If anyone has any ideas to help, please let me know! -Thanks!

Yep, I got v82.12 which is beta its so new. I did try the Drivers that came with it [v81.95], and also [v81.98], and this problem occurs with all three drivers I've tried.

I did call ASUS, and they told me to take one stick of RAM out, so I did, and it still crashed, then I tried the other stick, same deal. I tried removing the sound card, I tried it with the sides of my case off for the best cooling. All gives the same result, so I might call ASUS again, and see what else they've got for me.

chipset drivers maybe? My and others SLi has problems as well, but different ones. My guess is also driver issues, it could be a stability issue but then, I dont know how. Are they both hooked up to a really good power source?

btw: you must be filthy rich

Yep, I am using my Ultra X-Connect 500w PSU, and for the graphics card, I am using the AC adapter for it, which plugs directly into an outlet in the wall. I doubt its a driver issue, but I could be wrong. I've updated everything to the latest I can find. I am not sure what's going on with it..
