HP 8 GB DDR4 2133 MHz registered ECC DIMM

This 8 GB DDR4 module runs at 2133 MHz with CL15 timings and 1.2 V operation. It is a single-rank, registered ECC DIMM built for HP ProLiant Gen9 servers. The part targets administrators who need to expand memory capacity in supported rack, tower and blade systems.

288-pin DIMM with registered ECC and ultra-low

The green PCB carries a 288-pin interface that slots directly into compatible ProLiant motherboards. Registered signalling and ECC protect data integrity under continuous workloads. Ultra-low voltage operation reduces power draw per module while maintaining stability in dense configurations.

Upgrade for Gen9 ProLiant BL460c DL160 DL180 DL360

This module replaces lower-capacity or non-ECC DIMMs in the listed Gen9 platforms. The jump is worthwhile when workloads demand registered ECC protection and higher per-slot density. It is not for systems that require unbuffered memory or speeds beyond 2133 MHz.

Questions about this item

Does the DDR4 2133 MHz CL15 ECC registered module run at the full 2133 MHz on a ProLiant DL360 Gen9?

Yes, the module is rated 2133 MHz (PC4-17000) with CL15 timings and will operate at that speed on supported Gen9 platforms.

Will this 288-pin DIMM fit the memory slots in a ProLiant BL460c Gen9?

Yes, the 288-pin DDR4 DIMM form factor matches the slots in the BL460c Gen9 and other listed Gen9 servers.

What is the correct order for populating the DIMM slots when adding this single-rank module?

Follow the server's memory population guide; typically fill the lowest-numbered slot of each channel first, and ensure registered ECC modules are installed in matched pairs per channel.
