MAJOR SLI PROBLEM

My system:

* Apevia Xplorer Case
* Intel Core 2 Quad 2.33 mhz processor
* XFX 750i sli 1333 fsb motherboard
* 8gb (4x 2gb) OCZ 1000mhz overclocking RAM
* 850 watt COISAIR TX power supply
* Artic Cooling 7 heatsink
* 2 sli SPARKLE SX96GT2048D2-HP GeForce 9600 GT 2GB 256-bit GDDR2 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Cards (4gb total)

The problem i am having is that my system runs perfect until I go to play games. When i am playing any graphic intense games the system will function fine for a minute or so and then freeze my whole system. I then have to restart and try again, getting the same results. I can take out one card and the games function normally. Any suggestions ?

try it with 2 sticks of your memory out and tell me what happens. nvidia boards become problematic when they are that loaded down with RAM.

i may try the differnt timing voltages or just send the cards back and get 1 gb cards and not even worry about it cause i need 8 gb of ram. Just wanted to see if there was a quick fix .... or if the cards are actually defective or what not

2 9600gt shouldn't overheat in sli they aren't normally dual slot cards but you should check the head maybe one had improperly set heatsink. Also have you tried playing games with both cards in and just turning off sli feature. Leave all the stuff in just turn off do you want sli.

else ram suggesion with 8 gigs is a good bet.

i am not sacrificing my ram to get it to work ... i will probly get another 1 gb 9600gt series card ... any thoughts ... want a cheap but good 1 or 2 gb sli card. also i returned one of the cards and will try using just one and see how it goes i also returned the 850 corsair and got a 650 watt ultra pro ... i believe i shold be able to run one card off 620 watts ... so that should work and if it does i will run one card at 2 gb . if not i am gunna throw 2 one gb cards and go sli ....

I've seen several posts concerning the XFX branded mobos and how shite they are, which is a shame as I have always liked their graphic cards. I feel your pain mate.

sparkle cards 2gb work fine great for gaming .... 5.9 in vista testing .... highest ... it was a psu issue ... required 850 watt power supply and ultra pro x3 850 works great returned mine and got it today and both cards work perfect !!!!!!
