DL580 G3 & VMware 5.1 U1 - Enable 64bit OS Support & SAHF and LAHF support

Inherited three GL580G3's and all seem to be running same stepping CPU and BIOS.  On two hosts I can install and run (for a limited time to migrate VM's to other host) ESXi 5.1 U1 without issue, but on the third it won't install.  I get a PSOD that prevents the install  complaining about SAHF and LAHF support missing.  I have checked the BIOS on a working host and do not see any differences.

 

Thanks!

Do all 3 servers have the same System ROM BIOS?

All are running P38 which is the latest.  I am going to try reflashing unit that is not operating.  The SAHF & LAHF support was what I was looking to enable.  But based on an VMware KB the CPU's must be different in the problem DL580 since the Potomac CPU's were dropped.

 

Will need to probably pull the processor tray on a working unit and check.

It maybe that the working units have the 3Ghz 7040 series processors which per VMware KB were not dropped until 5.5.
