Product: Hp Z820
Operating System: Microsoft Windows 10 (64-bit)

I have a Z420 now but would like to upgrade to a Z820 due to some of my software requirements.  Can I use the same CPU and Memory chips in the Z820 from my Z420?  I currently have an E5-2680 2.7 mhz 8 core now in the 420.

Thanks

****corrected*   I meant Z820 not Z840 ... sorry for the confusion... I corrected the text above****

no, nothing will transfer over except for the hard drives if going from z420 to z840

 

yes, ram/2600 cpu's will xfer if going from z420 to z820

 

your post in not clear as you mention both z840 and z820

 

z420 ddr3 ram  /  z840 ddr4 ram

 

cpu's z420  cpu-e5-1600/2600 series ("v2" is ivy bridge) no support for v3/v4 cpu's

 

z840  v3 and v4 cpu's "Haswell" not backwards compatible with v2 cpu's

🤓Thanks for the reply, and for pointing out my error.  I meant the 820 not the 840.
