Server Memory Upgrade

This 8GB DDR4 module is built for servers that need error-correcting registered memory. It targets administrators expanding capacity in HP-compatible platforms to support more virtual machines or reduce paging.

DDR4 2666 Interface Limits

The PC4-21300 rating sets a maximum data rate of 2666 MT/s at CL15 latency. Systems that cannot run at this speed will downclock the module, and registered buffering adds one cycle of command delay compared with unbuffered DIMMs.

Registered Build and 288-Pin Fit

Major-brand DRAM chips and a 1.20 V operating voltage keep power draw predictable in dense configurations. The 288-pin registered form factor requires a motherboard slot wired for RDIMMs; it will not seat in UDIMM-only boards.

Questions about this item

Should I pick the 8GB RDIMM or a larger capacity for my HP server?

The 8GB 1Rx8 module fits any slot that accepts PC4-21300 DDR4-2666 registered ECC memory; add multiple sticks to reach the total capacity your motherboard supports.

What does the PC4-21300 rating deliver inside a running server?

It provides a 2666 MT/s data rate at CL15 latency, giving the memory controller the bandwidth it expects for DDR4-2666 workloads.

Is the 288-pin DDR4 interface compatible with standard registered DIMM slots?

Yes, the 288-pin registered DDR4 form factor matches the mechanical and electrical keying of every server board designed for DDR4 RDIMMs.
