I think your system is overheating. Get some case fans blowing on those video cards, bring your clocks down, or buy 2 Zalman VF-900's and stick them on your video cards. If its not that, then you might want to try updating motherboard BIOS. If that doesn't work, a clean copy of Windows might fix it. Hope you get everything working, keep me updated :).

i got 2x 120 fans plus one on the side a lot of clerance between the cards i dont think heat its an issue plus where do i get new bios from?

Go to http://www.biostar-usa.com/downloadmain.asp, find your board's model, go into the support section, download the latest bios, and they should have a program that will flash from windows. If this doensn't solve your problem, I'm betting there's a loose cooler on your 7600GT's.
Edit- whoops, bad link, lemme find the right one...alright link fixed.

If you motherboard supports PEG, change the "PEG Link Mode" from "Auto" to "Normal" or "Disabled". This can help stability a lot.

PEG stands for PCI-Express Graphics, so it would make sense that your MOBO manufacture may have overtuned something in their BIOS.

lol I learned something today :D. I love having a simplified motherboard, all I had to do was switch primary graphics adapter to PCI express, and I was set lol. Thanks for letting me know.

let me try bios...see what happends....

[bigbadwolf284]

rolled back driver upgraded bios everything worked good for a while....but game froze up again i went to cjeck temps and gpu1 was arround 75degrees ...can that couze games 2 freez up?

[zekrahminator]

Yes lol...you need to get yourself some aftermarket coolers. Zalman makes compact ones, work fine in SLI, are quiet, and cool video cards to very nice levels. I'd reccomend VF-700, or definitely VF-900 if you can afford it.

on heavy loads temps get to gpu1 85C gpu2 arround 74C:shadedshu

Try updating your mainboard bios, id deffinately suspect that first as its not been updated since last year. Just look at the DFI bios for example if you wonder what i mean, early boards had problems with the 6600GT in sli and DFI needed to fix it in a later bios.

your gpu temps are also very toasty, if you cant afford 2x NV silencers or 2x Zalman VF900s just remove your stock coolers, clean all the thermal crap off, lap the coolers to a nice smooth finish, apply some AS Ceramique, and if need be grab nibitor and mod fan speeds to 100% in 3D and like 60% in 2D

updated everything....stil freezes....decided 2 do step up program with evga......getting 7900gt oc now,.....:rockout:

[zekrahminator]

Believe it or not, its alot cheaper to get two Zalman VF-900's then two 7900GT OC's :p.
