8GB DDR4 2666 ECC Registered RDIMM

This 8GB DDR4 module runs at 2666 MT/s with CL15 latency and 1.20V operation. It uses a 288-pin registered DIMM layout with a single-rank 1Rx8 organisation and on-die ECC. The part is built with major-brand DRAM and matches HP part number 868841-001 for drop-in server upgrades.

Compatibility checklist before ordering

Confirm that your server platform accepts registered DDR4 RDIMMs and supports the DDR4 2666 speed grade. The memory controller must be able to address 1Rx8 modules at the rated voltage. Verify the maximum supported capacity per slot and the total number of populated channels allowed by your specific motherboard or system documentation.

Sustained-load behaviour

Registered buffering reduces electrical loading on the memory bus, helping maintain signal integrity when all slots are populated over long periods. ECC correction handles single-bit errors without interrupting workloads, which is critical for virtualisation and database tasks that keep memory fully utilised. The 1.20V nominal voltage keeps power draw predictable during continuous operation.

Questions about this item

Does the Brute Networks 868841-001 RDIMM arrive as a single 8 GB stick or do I need to buy anything else to install it?

The module ships as one 8 GB 288-pin DDR4 RDIMM; no extra brackets, cables or software are required — just an empty DDR4 RDIMM slot on a compatible server board.

I see 2666 MHz CL15 and 1.2 V listed — which spec should I match when picking a capacity for my HP server?

Match the DDR4-2666 (PC4-21300) speed, CL15 latency, 1.2 V voltage, ECC registered and 1Rx8 rank; any capacity you add must carry those same ratings to run without down-clocking.

What does the 2666 MHz rating actually deliver once the RDIMM is seated in a live server?

The module transfers data at 2666 MT/s with CL15 timing at 1.2 V, giving the memory controller its rated bandwidth so the CPU can feed more virtual machines and reduce swap activity.
