i have an xfx 8600gts. i have vista ultimate. games freeze then return. i also get abut 5200 in 3d mark 06. i have a dell power supply from my dell E520. i have the newest drivers. i wonder if the psu is too small. it is a 350 watt but dell doesnt realese actual wattage so it is about 450 with dual 12+
Was the previous video card driver uninstalled before this video card was installed? Power supply shouldnt be a problem unless it is failing, you can also try disconnecting everything from the power supply except the video card, motherboard and main hard drive to see if this helps. Try also underclocking the video card by about 5-10 MHz at a time to see if this makes a difference. I recommend you start a support ticket at www.xfxforce.com and then PM me the ticket number.
I have a XFX 8600GTS (Extream not XXX) and my powersupply is 305 watts and dual 12v 18A rails, same as the guy with the E520. Mine is also freezing, It mostly happens Halo and NFS: carbon. It only happens after around 15 minuetes of gameplay. I do NOT think its power, rather i think it is heat realated. First, the fan does not really turn on during heavy gameplay it alwyas stays at a light amount, and second I messured temps and after 10 minutes of 3dmark06 the temps were at ~75c. I have a fealing the fan (if not working correctly) can be fixed in drivers. Also, i tried underclocking (oohh, also, it has never been overclocked past factory which is 720, 2180), and when i try to underclock it says the GPU test has failed. Can someone, hopefuly the very helpful guy from XFX help me.
some extra info:
I have a pentium D 940, 1 CD/DVD drive, one SATA 160 7200RPM HDD, 1 120mm fan, 2 gigs of 533mrz RAM, Vista ultimate, 3dmark06 score of ~5200, and a dell 945G mobo
Also, I used to use a 7600GT and it worked fine
