[REQUEST] Acer Exstensa 5220 cpu mod

[Suds]

Hi, i'm looking for modded bios for extensa 5220, currently I have T9400 with bsel mod for it to work.
 Got my hands on QX9300 I did quad-core mod from forum (pin stuff and GTLREF connected) but all i hear upon booting is 2 short beeps.

 So my guess is that it might be unsuporrted bios wise?
My current bios is 1.35 
 Would be really glad for any help

Show all pinmods on your QX9300.
BTW: Your motherboard has two phases for VCC_CORE only.

I have it done just like here (these pins don't make contact) + gltref 1 and  gltref 2 connected + ofc forcing bsel for 800mhz

(just to be sure I again tried without connecting gltref, no difference)

I have no ideas.

A friend of mine did a mod that he found in an old forum at least 10 years ago, I rember that the ram was the problem and that he had to downclock his CPU.
I found this and i don't know if i can post link to other forum, If i am wrong please delete my Reply Admin:
