Z840 support 32GB ecc rdimms?

[mwx]

There seems in a previous some confusion and a missing link currently to answer whether a Z840 supports 32GB ecc rdimms?

Is it limited to 128GB per processor if usable or is 256 possible? Would 4 Samsung32gb 4DRx4 PC4-2133P-LD0-10-MB1 Registered ECC Memory work per processor?

Hi:

Below is the link to the HP Z840 Quickspecs.

HP Z840 Workstation (zworkstations.com)

Page 15 provides the general memory specs, and pages 19 & 20 provide the detailed memory specs.

One of the versions of the quick specs hat system noise listed with 8 32GB  rdimms, but unless I should find out otherwise, I'll accept as solution 16 x16 rdimms as max for two cpu.
