771 xeon does not boot OS

[Benedoge]

Hi there ,

I today bought a modsticker for a 771 xeon (L5420)  in order to mod it to an 775 processor . 

But when i fire up my computer , I am stuck in the bios , even though I have connected to the system on which my OS os located.

Hmm. Interesting.

 

That picture you posted isn't actually the BIOS, just a point of interest.

 

I would imagine your board doesn't have native support for Xeons and therefore cannot boot or do anything past that screen.

OK . I will then have to mod the bios ? Maybe ? But how wuold I do that ? ?

You'll need a BIOS revision from the support page of your motherboard, and a CPU that will work on the current BIOS in order to flash it. You might be better off just getting a non-Xeon LGA771 CPU and using that, Xeons aren't exactly the best for gaming if I recall correctly.

The picture you are seeing is just the P.O.S.T. screen -- that is not the BIOS.

 

Either the motherboard does not support the CPU (just incapable, not software/firmware limited), or current BIOS version is incompatible.

 

From what I can see you are using a Gigabyte GA-945GCMX-S2 motherboard.

https://www.gigabyte.com/Motherboard/GA-945GCMX-S2-rev-66#support-dl

 

The P.O.S.T. screen indicates you are on BIOS version F4 -- which is dated 2007/05/24.

The Gigabyte website shows the latest BIOS version being F6i -- dated 2009/10/06.

 

Try to update the BIOS (using a compatible) CPU, and try again.

The motherboard is clearly not recognizing the chip properly at its current state...

Intel (R) Xeon (R) CPU B.93 GHz (266x71)

 

The Gigabyte board DOES support 1333 MHz FSB CPUs, so there is a chance the Xeon L5420 will work...

771 xeons aren't the best for anything really unless you have 2 or 4 of them maybe.

771 was a server socket - so it might be hard to find non-xeon CPUs for it.

 

the only 771 CPU mentioned on wikipedia that is not a xeon is the Core 2 Extreme QX9775.

i'd say that is a myth. why exactly should they not? i have not noticed a difference - that is - if it's at the same architecture and clock speed

@Benedoge is using a LGA 755 motherboard.

It is using the 771-to-775 sticker mod, to make the LGA 771 Xeon work on a LGA 775 board.

You have to mod the BIOS to include the xeon microcode, otherwise you wont get beyond POST screen.

 

Notice the CPU name is garbage, that is your problem.

Ok I used the following tutorial form delidded.com

 

https://www.delidded.com/how-to-update-cpu-microcode-in-ami-bios/

 

In step four you have to open your BIOS in the programm called MMtool.

The problem i engaged is , that i got the following error message : "Error Loading Rom Image".

So I tried to insert every single file, which I got from the self-extracting BIOS file. Still , NO success.

Orry I am using a ga-945gcmx-s2 which does support 1066 FSB CPUs. So does that mean , my mobo wont support my Xeon L5420?

Sorry meant to say S2 (see the Gigabyte link) ... I'll change that in my older post.

Your motherboard supports up to 1333 MHz FSB (and ONE CPU that uses 1600 MHz FSB apparently).

 

Like I said, update your motherboard BIOS first, and see if that gets your Xeon working.
