Well, with the good one in and the bad one out, everything seemed to run fine, but I did get one reboot. I then turned off that setting that was discussed earlier in the thread (auto reboot without error message), so if it happens again I may see if there's something else wrong. However, I played GTA3 last night for about 30 minutes at 1152x864 with absolutely no slowdown and a solid framerate. Again, the only thing that stopped it is a program error of some sort (couldn't tell), and not a lockup. I was able to exit it and get back to windows.

Oh, and I found the temperature readings in the BIOS. They were well below what was said here (I think the CPU was at 43).

One problem though. Last night I put in both sticks again, and when I woke up, there were ALOT more errors. By themselves, one stick had 3 errors and the other had none, but together there were about 30 that I could see. What does this mean?
