Operating System: Microsoft Windows Server 2008 (64-bit)
I want to upgrade my CPU to X5680 (6 core). I bought a new MB from eBay to support this CPU. AS#460383-003", the board will support both the Nehalem and also the "Westmere" 56xx Xeons. I also have the proper heat sinks (via liquid cooling)
I was initlaily trying to boot the new MB with 2 CPU's but then I decided to try with CPU0 only since 2 CPU's did not work. When I powered up with both 1 and 2 CPU's all the fans started, EXCEPT the 2 memory fans. The memory fans got the jolt of power, spun for 1 revelotion and then stopped. The other fans are flying along fine. The machine recieves the power; fans, CD drawer can open, but the bios does not start. So after some research on this site I learned that the MB bios may not support the CPU's I have tried. I tried the following CPU's (1 at a time) on this 003 board: Xeon W5580, X5560, and X5680.
I have the most recent MB but the bios on it maybe old and does not support the 3 CPU's I have tried (just guessing now). I do find that hard to beleive since I have the latest version of the z800 MB. The eBay seller said the board was tested when they put up the ad. I have just sent an email to him/her asking what CPU they "tested" the MB with. If the CPU they used was much older than the 3 I have specified then I can just buy that one from eBay. I should be able to boot into the OS and then upgrade the bios to v3.60 Rev A April 14, 2016. Then switch to the 2 Xeon X5680 CPU's I want to use.
Can anyone provide some insight to what my issue could be? If the problem was related to the MB I would have imagined that the machine would have started to beep. Since it did not I think it is a bios issue. If it is a bios issue would it be possible for the 003 rev MB to not boot up the bios for the old W5580 or X5560 CPU's?
