Got a CPU from a trade from somone on hard, slapped it in my kr7a-raid, it smelled like burning, so i took it out immediatley. Complained to the guy so he sent me anotehr one, same thing happened with this one, i dont know if the cpus were dead before because when itold him i fried 2 cpus, he wasnt very mad. I decided to go newegg and buy a nice oem xp 1800+, i put it in, everything looks fine, i turn on the system, SAME thing happens... i was using a NON-CONDUCTIVE shim on all 3 occasions, then i put in a duron 850mhz with no shim and the system POST's fine, could it be the shim factor or what??
