Poweredge T430 CPU upgrade

Question

Hello I am currently running two E5-2620v4 CPU's and I'm trying to upgrade. I have two E5-2697v4 CPU's and it wont boot with both installed but it will with one installed. I am running them with a KX11M motherboard with two 750w PSU's. From reading other posts about similar situations I am gathering that the motherboard cant support the voltage draw from both CPU's. If thats the case then what CPU's should I be looking for when trying to upgrade to get some higher thread count?

There is also a higher PSU unit, 1100W which you may consider upgrading too. https://www.dell.com/support/manuals/en-us/poweredge-t430/T430_OM/supported-configurations-on-poweredge-t430-systems?guid=guid-63936338-ecd6-48a5-b6a4-bcf927a9bb7d&lang=en-us. KX11M is a V3 motherboard, hence, I am referring to the version to provide V3 version of PSU, DPN# Y26KX
