Dell Dimension E520 (0WG864)

Hello friends, I was wondering if possible to update microcode to unlock C2D E7XXX CPU (and Xeon L5408) in Dell Dimension E520 BIOS?

The current one is limited to older 65nm CPU (no SSE 4.1) and no LGA771 CPU (with mod) even though chipset (Intel Q965) is capable of running these CPU (as long as its 1066 FSB or lower)

With no update and incompatible CPU it will not fully boot and just has 100% Fan Speed no display

BIOS Link: https://dl.dell.com/bios/DM061-020400.EXE
Version 2.4.0

I will include CPU-Z images

Thank you for your time
