32 GB DDR4-2666 ECC Registered RDIMM

This 32 GB DDR4-2666 module is an HP-compatible registered DIMM built with ECC for data integrity. It operates at 1.20 V with CL15 latency and a 2Rx4 rank configuration on a 288-pin form factor. The part matches HP 840758-091 and uses major-brand DRAM chips.

Who this suits; who should look elsewhere

Server administrators who need to maximise installed capacity in HP platforms that accept PC4-21300 registered ECC memory will find this module a direct fit. It is not for desktop boards that require unbuffered non-ECC DIMMs or systems limited to lower-density ranks. Buyers needing speeds above 2666 MT/s or different voltage requirements must choose another specification.

Deciding specification: registered ECC

The registered buffer and ECC function together with the 2Rx4 organisation determine whether the motherboard memory controller can initialise this DIMM. Verify that the platform supports registered ECC DDR4 at 2666 MT/s and accepts the 2Rx4 rank layout before purchase. Compatibility with the specific HP part number 840758-091 is the primary indicator.

Questions sur cet article

Which server mainboard slot and memory standard must my system provide for this 288-pin DDR4 RDIMM to install?

The module fits a 288-pin DDR4 RDIMM slot; your mainboard must support registered ECC DDR4 memory at 1.20 V.

If I keep existing DDR4-2666 CL15 registered ECC modules, will this 32 GB 2Rx4 stick run at the same speed and timings?

Yes, it matches DDR4-2666 PC4-21300 CL15 1.20 V registered ECC, so the system will operate all modules at those shared specifications.

After installation, how can I confirm the module is recognised as 32 GB ECC registered memory running at 2666 MT/s?

Check the BIOS memory information or the OS memory report — it should show 32 GB, ECC enabled, registered, and a speed of 2666 MT/s.
