Hi Mark, I had similar problems with my AMD64 system. Whenever frequency scaling was enabled the machine would crash within a few hours of operation, even when it was idle. The kernel would oops a few times before finally locking up. I also saw video and database corruption, but generally the system was stable. The problem was a BIOS bug. It started when I increased my system RAM to 4 DIMMs. The CPU (AMD64 939 pin x2 4800) can't handle 4 DIMMs at the full speed of 400MHz; the BIOS is supposed to automatically slow the RAM down to 333MHz in this case, but that didn't work on my Gigabyte K8NS Ultra 939. I slowed the RAM down manually and the system is now perfectly stable. Maybe something like this is happening to you too. Memory tests did not show any fault by the way.
