HP Z Workstation Memory Upgrade

This 16 GB kit contains two 8 GB DDR3 registered DIMMs built for HP Z420, Z620 and Z820 workstations. It targets users who need error-correcting memory for stable operation in professional applications.

Registered ECC Modules for Quad-Channel Platforms

Each module is a 240-pin DDR3-1600 RDIMM running at 1.5 V with CL11 latency and a 2Rx4 organisation. The registered buffer reduces electrical load on the memory controller, allowing the workstation to populate all available slots. ECC circuitry detects and corrects single-bit errors without halting the system.

Replaces Slower or Smaller Factory Memory

The kit upgrades systems shipped with lower-capacity or slower DDR3 modules, raising total capacity to 16 GB and setting the memory bus to PC3-12800 speed. It is not suitable for platforms that require unbuffered ECC UDIMMs or non-ECC memory, and it cannot be mixed with those module types.

Questions about this item

Does the dual-rank 2Rx4 organisation and 1.5 V voltage cap how far I can push sustained throughput on a Z420, Z620 or Z820?

The kit runs at DDR3-1600 CL11 with 2Rx4 registered ECC modules at 1.5 V; the workstation’s memory controller and BIOS set the practical sustained-throughput ceiling.

How much heat and noise should I expect when the two 8 GB RDIMMs run all day in a loaded workstation?

The modules have no heat spreader and draw 1.5 V at DDR3-1600; they add minimal heat and zero noise, relying on the chassis fans already present in the Z420, Z620 or Z820.

What must my HP Z workstation already have to accept this 240-pin DDR3 ECC RDIMM kit?

A Z420, Z620 or Z820 with free 240-pin DDR3 slots that support registered ECC memory and a BIOS configured for RDIMM operation.
