Xeon Support for GA-X58-USB3

[guntarz]

Hello.

Is here a wizard who could mod the F5C BIOS for GA-X58-USB3 (rev. 1.0) mobo to support L5640 xeon?
Computer boots and works with all BIOS overclocking settings on default/auto. But as soon as i try any overclock (even memory XMP profiles) computer wouldnt boot. It just cycles on/off without post.

It also would not restart. It turns off but does not boot up again, just cycles on/off. After hard shutdown with power button and disconnection from power it boots up again (without necessity of clearing cmos).

This BIOS has full support for L5640.
No modification is needed.

my deepest appologies, tried just now few quick changes in clocks and voltages - indeed, with F5F BIOS everything woks!

Thank You!

One more thing caught my eye.. i noticed few post, that request microcode update/mod for CPU`s..
xeon L5640 has max turbo multiplier of 21. Is it possible to mod microcode to force turbo multiplier across all cores at all times?

i found that there is a feature in asus mobos called `multicore enhancement`.. is something equal possible for x58 chipset?
