A safe way to test a CPU

What is a safe way to test a cpu processor that is not currently residing in a computer? The processor is a 3.7ghz quad-core AMD, its worth keeping at least, I know. I do not know the exact specs other than the clock speed. The computer it was in is shot. Crappy pegetron violet-6 motherboard shorted the ground with the onboard video and conducted 32 amps through itself. YAY SPARKLY!
