First, found out what model motherboard you have. Intel's site does not show a WL810e, but they do show D810EMO, D810E2CB, D810E2CA3, CA810, and CA810E (http://www.intel.com/support/motherb...op/archive.htm
) This will help with identifying the motherboard: http://support.intel.com/support/mot.../CS-010687.htm
. From that, you can find out what the fastest processor is that you can use. Then start searching for it at the link above or just on the Internet. If the fastest you can go is like 800MHz, it's not worth it.
