8GB DDR4 2133MHz ECC RDIMM for servers

This 8GB DDR4 2133MHz ECC RDIMM module uses a 2Rx8 registered design and runs at 1.2V. It targets administrators who need to expand memory in compatible HP server or workstation platforms that require registered ECC DIMMs. The single stick adds capacity without occupying additional slots.

Registered DIMM slot with DDR4 2133 support

The module fits a standard 288-pin DDR4 RDIMM slot and operates at PC4-17000 speed with CL15 latency. Because it is registered, the memory controller must support buffered modules; unbuffered consumer boards will not accept it. ECC functionality depends on platform support for error-correcting code.

Replaces HP 759934-B21, 759934-S21, 762200-081.

This stick serves as a direct replacement for the listed HP part numbers when a system requires an 8GB 2Rx8 registered module at 2133MHz. The upgrade is worthwhile when the platform supports DDR4 RDIMM and the workload benefits from additional ECC capacity.

Preguntas sobre este artículo

How many ranks does the 8 GB DDR4 2133 MHz module present to the memory controller?

The module is organised as 2Rx8, meaning two ranks of eight-bit wide chips.

What is the typical operating voltage and resulting heat output when the RDIMM runs continuously in a server?

It operates at the standard DDR4 voltage of 1.20 V, so power draw and heat stay low during all-day workloads.

Which slot type and pin count must the motherboard provide for this registered DIMM to seat correctly?

The board needs a 288-pin DDR4 DIMM slot that supports registered ECC memory.
