HPE-compatible 64 GB DDR4 server module

This 64 GB DDR4-2666 module uses a 288-pin form factor and operates at 1.2 V. It is built as a load-reduced DIMM with 4Rx4 organisation and includes ECC for data integrity. The part is validated as 100 percent compatible with HPE part number 815101-K21.

Upgrade path for memory-constrained servers

It replaces lower-capacity DDR4 modules when the platform supports load-reduced memory and the same voltage. The jump is worthwhile when the workload demands more addressable memory per slot than standard registered DIMMs can provide.

Straightforward installation with matched kits

Each order ships with identically matched modules so mixed-rank or mixed-brand issues are avoided. The main risk is installing the module in a system that does not support load-reduced DDR4 or that requires a different rank configuration.

Questions about this item

Does this 64GB DDR4 module fit a standard 288-pin server DIMM slot?

Yes, it uses the 288-pin DDR4 form factor required by compatible HPE servers.

What is the correct seating procedure for this load-reduced 4Rx4 module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the 1.20V operating voltage in BIOS.

When should this 64GB DDR4-2666 kit be replaced to maintain server reliability?

Replace if memory diagnostics report correctable ECC errors rising above threshold or after a confirmed DIMM failure.
