Hi guys, I have a problem with running Xeon X5660 on GA-EX58-UD3R rev. 1.6 MOBO. PC start booting but can't post and didn't make any noises from speaker even with or without RAM/GPU/etc. It boot loops a few times then giving up and when I power on it's repeating.
Against forward questions I tried almost EVERY single bios version available at gigabyte site(except FA FD FE FG), trying to reset BIOS settings by putting battery from a few minutes to all night time, reset by clearing CMOS, tried different ram/slots. Cleared all mobo/case/sockets from dust. Checked CPU socket for bent pins( i7 920 D0 works just fine, and I checked visually and everything was just fine).
I know that this MOBO don't oficially support this CPU but there is plenty of examples in the net that people can use 6 core Westmere X56xx xeons on that board(e.g.
http://www.userbenchmark.com/UserRun/7042490 or
https://www.youtube.com/watch?v=Q2ELndxBtdU ). IDK maybe they have special modded bios or they have luck on a lottery or something fully random. I searched all the net for a solution for 3 days, several hours of reading and I felt to write in this awesome thread to look for a hand with that. Also I read many of pages in that thread but it's hard to read so many pages one by one and I could miss something.
Maybe someone can check if gigabyte's latest BIOS FK (
http://download.gigabyte.eu/FileList/BIO...1.x_fk.exe ) has up to date microcode for X5660, as I know its 206C2 microcode, but i don't know how to check Award Bios for that, AMI with MMTOOL was much more easier. I also have some theory but tell me if I'm wrong: can it be possible that when I insert X5660 and boots MOBO is using secondary(backup) BIOS which is FB bios I think(I had FB on the first startup as main BIOS and from what I read when I'm flashing BIOS only Main bios is updated) because of whatever reason (it's really confusing that after every BIOS update and loading default setting in BIOS on i7 920 everytime X5660 acted the same way: PC turn on running for a few seconds and shutdowns and repeats for a few times and giving up), not the main BIOS which is now updated to FK version?
Thanks for helping me.
