CPU Upgrade for Dell T420?

Is the 2470v2 supported?  It isn't on your list but it is a 2400v2 series processor?

The 2470v2 is on that list; it is the first one in the list.

I know this is an old thread but where did the CPU compatibility list come from? I cant find an updated one anywhere for the T420 or in the support docs/manuals etc.  

With the latest BIOS upgrades for 2020 I was just told by a Dell customer service rep that the V3 are now supported on the T420 as well as possibly other variants. Looking to purchase the most powerful CPUs compatible since the customer cannot migrate yet.  

I always like to confirm things in writing.....Can someone post a link to the updated list? 

Thank you

Mvincent2k,

There isn't a publicly facing list that is updated, other than parts listed for the server on the Dell page. The list that was supplied was an internal list. 

Regarding the V3 processors, I am not seeing anything showing they're supported, regardless of BIOS level. I am also not showing there any listed parts for them beyond V2's. It appears the 2.4Ghz 25MB E5-2470V2 (part # RR182) is the fastest listed.

Let me know if this helps.

Mvincent2k,

That is correct, that Hynix is the fastest quad ranked, it's part # JGGRT. There is another quad ranked 32GB dimm, but it is a low voltage 1333Mhz version, compared to JGGRT 1866Mhz. 

Let me know if this helps.
