Adding 2nd processor causes server to not boot

jgreywolf — Thu, 15 Nov 2012 06:59:25 GMT

We have a DL360 G7 that came with one CPU (5620). When I add a second CPU (5620) the fans go into a frenzy and it will not boot off the CD. I switched the 2nd cpu to the 1st slot - fine. I put the 1st cpu into the 2nd slot - fine. I just cant run 2 cpus...any ideas?

hi,

There some steps that you can check:

BIOS update

Memory config

but in the most cases , this issue is caused from a damaged part(CPU or systemboard). Please check for bent pins.

Thanks

BIOS and firmware at optimum levels.

we tried the original cpu in the second slot - fine

we tried the second cpu in the first slot - fine

this indicates to me that its not the cpus or the slots - its just running two cpus at the same time.

we actually have a second server that has the same issue and a third that is just fine with 2 cpus - poser, eh?

hi,

"we tried the original cpu in the second slot - fine"

Have You been able to boot the server only with 1 cpu in socket 2?

Thanks

Have you split your memory correctly across the banks ?

Yup - 8G on either side, swapped them around - RAM is fine.

Yup...well i think we tried every possible combination of CPUs and slots.

Keep in mind that we have 3 servers: one took 2 CPUs fine, the other two exhibit this problem.
