Can LGA 771 Cpu work on a LGA 775 Motherboard

Not without modifications and a custom BIOS that supports Xeon processors. http://www.overclock.net/t/1431723/mod-lga775-support-for-lga771-xeon-cpus Your motherboard hasn't been tested, but you could be the first one who does. Worse that could happen is a ruined motherboard and CPU.

Well, I'm no expert, but I would expect that on a socket 771 processor, "Pin X" performs "Function X" and "Pin Y" performs "Function Y". I also expect that on a socket 775 processor, "Pin X" performs "Function Y" and "Pin Y" performs "Function X". The pin mod sticker probably fools the motherboard socket into thinking each pin is performing the proper function.

For LGA771 CPU, land name A3# is Execute BIST (Built-In Self Test), it's pin No. M5 on LGA771, but this A3# pin is pin No. L5 on LGA775.
So the key is to exchange pin M5 and L5

I have this same motherboard. If you flash to the newest bios, then do the physical mod described in the article, then YES, the lga 771 DOES work! As a matter of fact, the MSI G31 is one of the easiest boards to mod for the Xeon! If you need help, join us in the lga 771 to 775 Support Group. I'm about to revise the article for rookies like me. The 2.8 bios WILL support the quad-core. That is the same cpu-family I am using.
