Server memory upgrade for HP ProLiant Gen10

This OWC kit supplies 128GB of DDR4 ECC registered memory in a matched pair of 64GB modules. It is built for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers. The modules will not work in standard desktop computers or alongside unbuffered or load-reduced DIMMs.

Sustained-load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller, helping stability when all channels are populated at 2933 MT/s. ECC corrects single-bit errors and detects multi-bit errors during continuous operation. JEDEC-standard timings of CL21 at PC4-23400 are maintained under extended workloads. Backward compatibility lets the kit run at 2133, 2400 or 2666 MT/s if the platform requires it.

Thermals, noise and power draw in normal use

Each module operates at 1.2V without a heat spreader, relying on server chassis airflow for cooling. Power consumption stays within standard DDR4 registered DIMM limits for the rated speed. The design adds no moving parts, so acoustic contribution is zero. ROHS-compliant construction avoids restricted substances.

Questions about this item

How much heat and power will the 1.2 V DDR4 2933 kit draw when the HP ProLiant DL560 Gen10 runs 24/7?

Each 64 GB module operates at the standard 1.2 V DDR4 voltage, so total power draw stays within JEDEC limits for registered DIMMs. No heat spreader is fitted, allowing unrestricted airflow through the server’s existing cooling zones.

What must already be installed in my HP ProLiant DX380 Gen10 for these two 2Rx4 ECC RDIMMs to work?

The server needs a DDR4 memory controller that supports registered ECC DIMMs and free 288-pin slots. The modules cannot be mixed with unbuffered or load-reduced ECC memory, so all populated slots must use the same registered type.

Will the PC4-23400 CL21 sticks run at 2933 MT/s alongside older 2133 MT/s or 2400 MT/s DIMMs I keep in the DL580 Gen10?

The kit is backward compatible with 2133, 2400 and 2666 MT/s speeds. When mixed, the memory controller will clock all modules to the lowest common speed, so the new DIMMs will downshift to match the older ones.
