I am having similar problems with some K6-2/350 and VA-503+ MB's design. Exact same symtoms, and if I move to the next lower speed, it works fine. Replaced processors, same problem. So it is either a widespread problem with the K6's quality control, or the VA-503+'s. Most people blame the memory, but I've tried enough different pieces of memory to know better, by this time.
