Overheating Graphics Card?

Hey guys,

Recently my computer has been resetting randomly when I’m playing some my high end games (Call of Duty 4, Medieval II). When I initially bought the games was not a problem. I am fairly sure that it’s not a software problem (all my drivers are updated, games are fully patched and I even did a re-installation of XP). My computer is about 1.5 years old, so I am wondering if this might be the result of old age. Usually I am running about 65-75 degrees when a crash happens (about 10-50 minutes into a game). Here are my specs:

E6600 Conroe 2.4GHz 4M shared L2 Cache LGA 775
ASUS P5B Deluxe/WiFi-AP Socket T (LGA 775)
SAPPHIRE 100168L Radeon X1900XT 256MB 256-bit GDDR3 VIVO PCI Express x16 CrossFire
Seagate Barracuda 7200.10 ST3320620AS (Perpendicular Recording Technology) 320GB 7200 RPM SATA 3.0Gb/s
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
Antec TruePower 2.0 TRUECONTROL II-550 ATX12V 550W

This is my first homebuilt computer, so I’m pretty new at trouble shooting. If I need to include some more details please tell me. Thanks for the help.

Your psu shows 19 amps per rail, thats barely covering a CF rig like yours, add in the age factor, a little heat and you may be overstressing it. Try one card, see if it holds up.

The x1900 series is a HOT HOT! card. I have a x1900xtx that ran at 90C+ with the stock cooler, it hit 95C at times. My buddy had a x1950xt 256MB and hit the same temp. All ran fine though.

You may want to look at the PSU, those cards do suck alot of power.

65-75C is really cool for those cards on load, how are you getting your temps?

That is a nice rig you have. Ever think about getting a different card? My thought is rather than replacing the PSU you can get a newer card that sucks less power and can use the current PSU. I ran my x1900xtx on my current rig with a 600W PSU that has the same 12v rail ratings are you. However I haven't heard spectacular things about those Antec PSU's.

It's probably just a crossfire card, not in a crossfire configuration.

I put a Thermalright HR-03 cooler on my x1900xtx with a 80mm fan and it dropped the idle and load temp 20C. Didn't sound like a hair dryer anymore. I had it OCed and it rocked the hot totty, till those 8800's came out.
