Problems adding second CPU

Posted on 2008-06-15
Last Modified: 2013-12-10
I have a Dell Poweredge 6600 currently with one processor. I purchased an additional processor and VRM for this system. When I installed the second processor, I got an error "missing CPU2". I thought maybe there was an issue with that CPU, so I ordered another one locally only to receive the same error. I tried both of the new porcessors in the CPU1 slot and they did not work there either. I have also updated the BIOS to the current revision. This is the exact same CPU (dell part number and code) that is currently running in the system. I can't imagine two dead CPU's, so I am puzzled. I really need to get this thing upgraded, so any help/thoughts would be appreciated.

What happens if you reverse the installation. Old processor in new slot and new in old? Also have you poked around in the bios  after updating it to see if something needs to be enabled for the second proc to work?

Yes, I did try and reverse the config and I then get misssing CPU1. So , neither of the two new replacement CPU's work in slot 1 ot slot 2. That led me to think I had the wrong CPU, but the codes are exactlly the same. I did poke around the BIOS, but the new CPU will not even work in a single processor situation.

Have you loaded the latest ESM firmware, as well?  That error seems to occur when the BIOS or firmware is not updated.

I did not update the ESM firmware, just the BIOS. I will run that update tonight. Even if that is the case, wouldn't the replacement processor be recognized in the CPU1 slot by itself just like the current running CPU?

Check the sspec on the actual processor markings to see if they are compatible.
The Dell Part Number labeling may have been in error.

Unless the esm suggestion works it does seem like it is somehow the wrong part. You know both sockets work now and the second cpu never does. Also you would think that after two tries that you should qualify for tech support even if your warranty has expired.
