I'm using bios 1603, and a seasonic 330W PSU. The errors appear to
happen at random, heavy I/O doesn't trigger it. I can rebuild world
without problems, so I guess the CPU is ok. The memory has been tested
and showed no errors. What's left is cables and mainboard. But how
error-prone are sata cables? Considering that I've got 50% failing...
Okay, maybe that should "prove" that the mainboard is faulty :)
