1TB DDR4 2933 ECC LRDIMM kit

This 1TB kit contains eight 128GB DDR4 2933 CL21 4Rx4 288-pin 1.2V ECC Load Reduced DIMMs. It is built specifically for the HP SimpliVity 325 Gen10 server platform. The modules are not compatible with standard desktop computers or unbuffered and registered ECC memory types.

Capacity for dense virtualization workloads

The 1TB total capacity provides headroom for running many virtual machines or large in-memory databases on a single node. Workloads that exceed this limit will require additional memory slots or a different server platform. The kit fills eight slots with quad-rank modules to reach the full terabyte.

Load-reduced design for signal integrity

Load-reduced buffering reduces electrical load on the memory bus, allowing the full 1TB population at 2933 MT/s. The 288-pin DDR4 form factor fits the SimpliVity 325 Gen10 DIMM slots directly. Modules lack heat spreaders, relying on server chassis airflow for cooling.

Questions about this item

Will these 2933 MHz LRDIMMs run in my SimpliVity 325 Gen10 if some slots still hold 2133 MHz modules?

The kit is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz DDR4 speeds, so it can operate alongside slower modules at the lowest common rate.

How do I confirm the 1 TB kit is recognised at CL21 after installation?

Check the server BIOS or iLO interface; it should report 8 × 128 GB DDR4 2933 PC4-23400 CL21 ECC LRDIMM modules running at 1.2 V.

Does the 8 × 128 GB package include heat spreaders or mounting brackets, or must I order them separately?

The modules have no heat spreaders and the kit contains only the eight 288-pin LRDIMMs; no extra brackets or cooling parts are supplied.
