HPE-Compatible 16GB DDR4-2666 Server Module

This registered ECC module delivers 16GB of DDR4-2666 memory for HPE server platforms. The 2Rx8 organisation and 1.20V operation match the original 838089?K21 specification. It targets administrators who need to expand capacity in supported Gen9 or Gen10 systems without purchasing OEM-labelled sticks.

DDR4-2666 Registered ECC Electrical Limits

The DDR4-2666 JEDEC standard caps the data rate at 2666 MT/s and the voltage at 1.20V for registered DIMMs. Registered buffering adds one clock cycle of latency but allows larger memory populations per channel than unbuffered modules. ECC correction protects against single-bit errors, yet the interface cannot exceed the rated speed or voltage without platform support that is not guaranteed by the module itself.

288-Pin Registered DIMM Installation Notes

The 288-pin form factor keys into standard DDR4 server slots; the registered design requires a platform that explicitly supports registered memory. Mixing registered and unbuffered DIMMs in the same channel will prevent boot. Population rules vary by server model, so the memory-configuration guide for the specific HPE system must be followed to avoid mismatched-rank or channel-interleaving errors.

Questions about this item

Should I pick the 16GB 2Rx8 module or a different capacity for my HPE server?

This module provides 16GB in a 2Rx8 registered ECC configuration. Choose it when your server requires that exact rank and density; other capacities will have different rank layouts.

What does the 2666 MT/s rating deliver once the DIMM is installed?

The DIMM runs at DDR4-2666 (PC4-21300) with a 1.20 V supply. Actual throughput depends on the server's memory controller and how many slots are populated.

How does the 288-pin registered DDR4 interface limit performance in practice?

The 288-pin registered DDR4 interface caps the module at the DDR4-2666 standard. The register adds one clock cycle of latency but allows higher capacities per channel than unbuffered DIMMs.
