Dell T5600 Processor Compatibility

Morning,

I am looking to replace my processor in my T5600. However, I am having a difficult time finding out what is compliant. Here is the info I know:

I currently have a Intel Xeon ES-2609 0 @ 2.4Ghz and a Dell 0Y56T3 Main Board.

I am only utilizing one slot of the two available, so would like to buy a pair. The socket set is FCLGA2011 for each.

I was looking possibly putting 2 of the ES-2906 V2 (Mfg # BX80635E52609V2)

However, not sure the differences between the V1 and V2. Does any know if this will work? Or what would be a good upgrade? \

Thanks.
