I have received an old server which has a xeon E5405 (2GHz) processor. I'd like to buy and add a more powerful cpu (something like Xeon X5492) which has a higher clock speed but the same LGA 771 socket. The aim is to improve the computational power with best bangs for bucks.
So I am am wondering whether it is technically possible to mix the cpus, and, if so, is it a good idea? That is, what are the possible downside of using the mix? Thanks
