DL180 G6 - Wont recognize 2nd processor?

Hello - I've got a brand new DL180G6, that boots up without any issue when only one processor is installed. as soon as I plug in the second one, the system health light blinks red and the server never boots. Take it out and it comes up just fine again. Anyone happen to have any thoughts on what might be causing this or how to correct? Thanks -

Verify both CPUs match.

Run firmware and BIOS upgrade before installing second CPU.

Yeah, check revisions - stepping etc on the CPUs. Upgrade firmware is a given one. You can also try to clear the BIOS.

Did you swap the CPUs too? So that running on one a single cpu with either of them works?

Did you install the DIMMs correctly? Maybe this proliant is sensitive in which order the slots are populated?


Can give some more hints.

Try one CPU at a time. See if both post properly. Try swapping the CPUs.

Re: DL180 G6 - Wont recognize 2nd processor?

Hi John,

Memory slots are mapped to Processor. so you need to check the memory configuration as per quickspecs.

Processor Part no and other things should match (stepping, speed etc.)

boot the system with one processor and update the system bios, Check the Power Efficiency Mode in system bios for processor and set it to Efficiency mode... if it is already on Efficiency mode then try Performance mode.

there are many settings in CPU configuration like core, multithreading, virtuatisation, excecute bit etc..
Load the default settings for CPU Configuration in system bios and now put the second processor.

If both the processors are tested on first slot and everything else is fine then it could be faulty processor slot and motherboard needs replacement.

hope this helps,
