I have an ASUS CM5571 with motherboard P5QL-M EPU (not to be confused with P5QL-VM or others), with current CPU Intel Pentium E5400. I was wondering if my system will support the Intel Core 2 Duo E8400. Following is my mobo displayed via CPU-Z. My mobo supports DDR3 memory; I'm not sure if this conflicts with the CPU I am trying to upgrade to. They are both socket LGA775. According to the ASUS mobo support, the motherboards with close enough model names to the one I have support said processors.
