Server Memory Upgrade

This 8 GB DDR4 registered DIMM adds error-correcting capacity to compatible HP servers. The module runs at 2666 MT/s with a CAS latency of 15 and operates at 1.20 V. It is built with major-brand DRAM chips and matches HP part number 838079-B21 for guaranteed compatibility.

288-Pin Registered Design

The 288-pin RDIMM fits DDR4 server slots that support registered, ECC memory. Its single-rank 1Rx8 organisation helps maintain signal integrity on densely populated channels. The module requires a platform that accepts registered ECC DIMMs and will not work in unbuffered or non-ECC desktop boards.

Sustained Workload Stability

ECC circuitry detects and corrects single-bit errors during continuous operation, reducing the risk of data corruption in virtualisation and database tasks. Registered buffering lowers electrical load on the memory controller, helping maintain consistent throughput when all slots are populated over long periods.

Questions about this item

Does CL15 latency limit throughput when the module runs at 2666 MT/s continuously?

CL15 is the rated timing at DDR4 2666; the module operates within that specification under sustained load.

How much heat does the 1.20 V registered DIMM produce during all-day operation?

At 1.20 V the module draws standard DDR4 power; registered buffering adds minimal extra heat versus unbuffered DIMMs.

What server slot type is required for this 288-pin RDIMM to function?

A DDR4 288-pin RDIMM slot that supports ECC registered memory is needed for this module to work.
