Ive definitely done my searching on this forum and i absolutely appreciate the response. I found quite of few models out there and some had 5650s running on them already. I got confused when i saw "Rev. 1" on the PCB. Then i read someone had a 5650 on the same Z600 "5520 Rev 13" chipset and that matched mine so i thought i could get lucky.
So i guess im seeing that the original just doesnt have the microcode to run the newer processors but the hardware CAN do so.
Ill look into a possible MB replacement or perhaps a BIOS mod first if possible.
