Capacity and Compatibility

This 16GB DDR4 module targets administrators upgrading HP ProLiant Gen9 or Gen10 servers that require registered ECC memory. It matches the 838081-S21 part number and runs at 2666MHz with CL15 latency at 1.20V.

Upgrade Value

The stick replaces lower-capacity or slower DDR4 RDIMMs in supported bays, reducing paging when virtual-machine density is increased. The jump pays off when current memory limits the number of concurrent workloads rather than CPU throughput.

Installation Notes

The 288-pin registered DIMM seats like any standard DDR4 RDIMM; the system must support registered ECC and 1Rx4 organisation. Mixing ranks or voltages can prevent POST, so populate identical modules per channel.

Questions about this item

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR4 form factor used by registered server memory slots.

What is the correct seating procedure for this registered ECC module?

Align the notch with the slot key, press firmly until both side latches click, and verify the module height matches adjacent RDIMMs.

When should this 16GB 2666MHz CL15 kit be replaced?

Replace if ECC correctable error counts rise steadily, if the server logs uncorrectable memory errors, or when a capacity upgrade is required.
