I recently purchased my XFX 9800GTX+ and am having issues with random locks like many people have been describing on here and on the NVIDIA forums. I can go back to my old 7900gs and never experience one lock up but as soon as I plug in the 9800 my computer will lock up while I'm using it. The lock-ups are not limited to in game either most of the time I will be running a virus scan or downloading updates for steam games when the lock-ups occur. It only appears to happen when there is a lot of data access which is why I feel it may not even be the card. I have checked everything in my system and the only thing other than the video card that I have found that may be the culprit is my ram. Using CPU-Z I have found that my motherboard has set the timings and voltage to there default values for the mobo so I'm wondering if that could cause problems as they don't match the rams voltage and timings?...
Some of my system specs (sorry I don't have more I'm on a work computer right now but can provide more once I'm home)
CPU: AMD - X2 5400+ @ 2.8GHz (Not overclocked)
Memory: CORSAIR - XMS2 2GB (2 x 1GB) DDR2 SDRAM DDR2 675 (PC2 5400)
- Timings and voltage reported by cpu-z: 5-5-5-18, 1.8v
- Timings listed for ram: 4-4-4-12, 1.9v
Currently I'm running the latest Nvidia driver (and yes I went through the whole process for proper driver upgrade) and yes I have gone back to the old driver and noticed less lockups in the past. I adjusted my memory settings last night with the latest driver and it seems to have also helped with them so tonight I will downgrade my driver and see how things go with the old driver and fixed memory speeds.
