HP Z420 Z620 Z820 memory kit

This A-Tech kit supplies 64GB of DDR3 1600MHz registered ECC memory across four 16GB modules. It is built for second-generation HP Z workstations and uses a 240-pin DIMM form factor with 1.5V operation. The CL11 2Rx4 design targets reliable server-grade performance.

Workstation owners needing registered ECC

The kit suits owners of HP Z420 Z620 Z820 workstations that require registered ECC RDIMM modules. It is not for systems that only accept unbuffered ECC UDIMM memory or for platforms with a different DIMM pin count. Mixing with unbuffered modules is not supported.

Registered ECC RDIMM requirement

The single specification that decides fit is the registered ECC RDIMM design with 2Rx4 organisation. The motherboard must support registered error-correcting DDR3 DIMMs at 1600MHz. Unbuffered or non-ECC memory will not work in its place.

Points forts

  • ECC registered RDIMM design detects and corrects memory errors
  • 2Rx4 dual-rank organisation maximises density per DIMM slot

Questions sur cet article

Do I need an HP Z420, Z620 or Z820 workstation for these modules to function?

Yes, this 64GB kit is designed for second-generation HP Z workstations — the Z420, Z620 and Z820 — and requires one of those systems to operate.

Can I keep my existing ECC UDIMM modules and add these RDIMM modules together?

No, ECC Registered RDIMM modules cannot be mixed with ECC Unbuffered UDIMM modules; the system will not recognise the mixed configuration.

How can I confirm the kit is running at DDR3 1600MHz after installation?

Enter the BIOS or use a system-information utility and verify the memory speed shows 1600MHz (PC3-12800) with CL11 timings at 1.5V.
