Hello HP community & staff,
I need to upgrade my HP Z420 v2 workstation to the top spec of 64 GB 1866MHZ DDR3 RAM.
Can someone please confirm the following memory is compatible with the HP Z420 v2 mainboard?
CPU is the Xeon E5 1650 v2, PSU is 600 watt option:
Hynix 64GB 8X8GB PC3-14900E 2Rx8 DDR3-1866MHZ ECC Unbuffered
Its my understanding that the HP Z420 v2 requires ECC Unbuffered, I just need confirmation because I just found ECC Registered RAM in a Z420 v1 I have laying around that works fine and want to be sure I'm purchasing the right RAM for my v2.
I really appreciate the help in advance.
Best,
Chris
Edit: Found this great article explaining ECC registered vs unregistered:
ECC Registered vs Unregistered - Serve the Home
Also found out from the forums here that the HP Z420 does indeed work with both ECC registered & unregistered/unbuffered (I can also prove that as I have a Z420 running with 32gb registered).
From the article though seems as though unregistered would be the way to go for the Z420, seeing how its a performance-oriented system I don't think you'd want that extra hop between the CPU and Memory. Probably also explains why the manual states to use Unbuffered, but this is a recommendation, not a requirement.
