DL360 G5 CPU upgrade.

[AlexOz]

Hello.

I have a DL360 G5 server and Xeon dual core 5120 CPU in it and i am planning to install the second 5120 CPU.

This processor model has 2 steppings: B2 and G0. The only difference between these CPUs is voltage range. B2=1.0V-1.5V, G0=0.85V-1.5V.

Will my server work if it run with 2 CPUs with different steppings each?

If not, then how to determine current CPU's stepping if i am running XenServer on it?

Maybe the HP provides with only one stepping models in market?

Hi,

Its always recommended to update the BIOS before adding the second processor.  The second processor should be of the same model/specs as of the first processor.

Regarding the change in Stepping for Intel 5120 processor, here is an article from HP for its Workstation model, I could not find a similar document for servers though.

Also refer to "Product Change Notification PCN 107467- 00" from Intel.

Dual-Core Intel Xeon 5100 Series Processors, PCN107467-00, Product Design, B2/3 to G0 Stepping Change.

I guess that both the processors should work togeather, provided the BIOS/RBSU is updated on the server.

I havent tested this configuration myself but its the best guess/tip I can give.

Good Luck!

Thank You Suman_AN.

This info was very useful. In a couple days i am going to purchase another CPU. We'll see how it is working.
