Hi all, my first post after a lengthy review. Great work to all contributors.
I picked up a E5440 xeon and an adapter on ebay and very quickly upgraded an asus PK5 green board to a quad CPU for ~$50. Nice!
Now I have a few optiplex 755's that I want to mod. I bit the bullet and bought another E5440 and adapter but it doesn't work. I confirmed that it works on the PK5 board. I'm running the latest bios A22. The computer power light is amber instead of amber (~1sec) then green. No post beeps, nothing on screen, etc. Is this an issue of needing to get the bios cpu codes modified in the A22 bios (if that is possible with this bios) or is there another issue that I am over looking?
Thanks in advance for your help.
