R420 CPU upgrade / Dual CPU

Question

Hi guys, I'm wanting to upgrade my R420 CPU but figured i would look at dual CPU while I was at it. Is there anything else I need before being able to add a second? Thanks

Hello,Please remember to update the firmware before doing any upgrade BIOS, iDRAC, CPLD. Please be aware the CPUs have to be identicalProcessor type One or two Intel Xeon processors E5-2400 and E5-2400 v2 product family The R420 can use two types of PSUs (350W and 550W). I recommend using 550W in your system because power consumption will increase when you switch to the dual processor. Hope that helps!

Thank you for your reply.

I have selected the Intel Xeon Processor E5-2450 V2 and can get two of the same so that's great. Just wasn't sure if there were any other hardware requirements before changing. I have 2x 550W also

Thanks

Hmm searching the part code gives a similar result to the one below (the one i had selected) so i should be okay. I read I may need a riser or something?

DELL-Erman O · Answer

Hi, probably you may need a riser. I found this below. Please check do you have it or not in your current configuration.

NUMBER OF PROCESSORS	EXPANSION CARD CONNECTOR
NUMBER OF PROCESSORS	RISER 1	RISER 2
One	PCIE_G2_X4 iDRAC_Enterprise	PCIE_G3_X16
One	PCIE_G2_X4 iDRAC_Enterprise	PCIE_G3_X16
Two	PCIE_G3_X16 iDRAC_Enterprise	PCIE_G3_X16
Two	PCIE_G3_X16 iDRAC_Enterprise	PCIE_G3_X16

NOTE: The expansion-card risers listed in the above table cannot be interchanged between single- and dual- processor systems.
