What this module is

This is a 128GB DDR4-2666 ECC LRDIMM built for HP servers that accept 8Rx4 registered memory. It runs at 1.2V with a CL15 latency and uses major-brand DRAM chips. The module is designed to maximise installed capacity in compatible rack or tower systems.

The specification that decides fit

Your server must support 288-pin DDR4 LRDIMMs at the PC4-21300 speed grade and accept an 8Rx4 rank configuration. If the platform only takes standard RDIMMs or a lower rank count, this module will not be recognised.

Installation notes and common issues

Installation follows the usual DIMM-slot procedure: align the notch, press until the latches click, and verify the full 128GB appears in BIOS. The most frequent problem is a rank or population limit in the server's memory controller that prevents the module from posting.

Questions about this item

What does 2666 MT/s mean for real-world server throughput?

DDR4-2666 runs at 2666 million transfers per second; actual bandwidth depends on the memory controller and how many channels are populated.

What does PC4-21300 tell me about the memory interface?

PC4-21300 is the DDR4-2666 JEDEC designation for a peak data rate of 21300 MB/s per module.

Will this 288-pin LRDIMM fit my HP server memory slots?

The module uses the standard 288-pin DDR4 LRDIMM form factor used in compatible HP servers; verify your system supports 128 GB 8Rx4 LRDIMMs.
