I've been using this board for a few months now, and I really like it, but I have been having the same crashes that some others have mentioned. Right now, i'm having a kernel panic almost exactly every 2.5 days. I was getting kernel panics about every 1.25 days a while ago, but resetting the BIOS settings has brought me back to 2.5 days between crashes. I'm not convinced that it has to do with heat - the time between crashes is very repeatable and doesn't seem to depend on load at all, although sometimes sudden network or USB activity can trigger them when it's almost "time" for one to occur anyway. The GPU heatsink doesn't feel that hot to me, either, although that is of course highly subjective without a program to measure it. I really don't want to RMA it, since the last time I did that (long story), it took over 3 weeks to get back to me and I can't be without it for that long. I leave it running 24/7 and use it to record TV programs with EyeTV as well as for file and print sharing, so it is really important that I get it working stably. If anyone has figured out anything about these crashes, it would be greatly appreciated. Other than this problem, I have no complaints whatsoever with this board, but if I can't fix this, I might just have to sell the parts and buy a mac mini, which I really don't really want to do either. If all I need to do is put in a new gpu heatsink or add another fan, that's great, but I'd like to know that it's going to work before I spend the money on it.
