HPE-compatible 16GB DDR4-2666 RDIMM

This 16GB DDR4-2666 ECC Registered RDIMM is built for servers that require HPE part number 840756-V91 compatibility. It delivers 2666 MT/s throughput at 1.2 V using major-brand DRAM chips in a 2Rx8 organisation. The module is validated for 100 percent compatibility with the original OEM qualification.

288-pin registered DIMM for multi-DIMM servers

The 288-pin registered design adds a buffer that reduces electrical load on the memory controller, allowing larger memory populations per channel. ECC circuitry corrects single-bit errors to protect data integrity in always-on workloads. Identical modules are supplied together to maintain matched timing across populated slots.

Low-voltage DDR4 operation at 1.2 V

Standard 1.20 V DDR4 voltage keeps power draw modest per module, reducing thermal load inside dense chassis. Registered buffering and ECC add minimal latency overhead while enabling stable operation at the rated 2666 MT/s speed. The module runs within normal server airflow without requiring additional cooling measures.

Questions about this item

What sustained throughput limit does the PC4-21300 rating impose on this module?

The PC4-21300 rating indicates a peak transfer rate of 21300 MT/s, which defines the maximum data rate the module can sustain under continuous load.

How much heat and power does the 1.20V registered design produce during all-day operation?

Operating at 1.20V, the registered DDR4 module draws low power and generates minimal heat, while the register buffers signals to reduce electrical load on the memory controller during extended use.

Which server platform must already support 288-pin DDR4-2666 ECC registered memory for this module to work?

The module requires a server motherboard with 288-pin DDR4 slots that accept 2666 MT/s ECC registered RDIMMs, such as HPE platforms qualified for part number 840756-V91.
