128GB DDR4 2666 LRDIMM

This 128GB DDR4-2666 LRDIMM targets server administrators who need maximum memory density per slot. The module operates at PC4-21300 speed with a low 1.20V voltage. It uses an 8Rx4 rank configuration to deliver high capacity in a single 288-pin package. ECC and registered buffering protect data integrity in mission-critical workloads.

Major-brand chips and HP compatibility

Each module is built with Samsung, SK Hynix or Micron components that meet or exceed OEM specifications. The part is equivalent to HP 868845-001 and guaranteed compatible with systems requiring this specification. Registered signalling and load-reduced architecture reduce electrical load on the memory controller. This helps maintain stability when populating every available DIMM slot.

Upgrade path for capacity-bound servers

This LRDIMM replaces lower-density RDIMMs or LRDIMMs when the platform supports 128GB modules and 8Rx4 organisation. The jump is worth it when virtualisation density, in-memory databases or large dataset caching hit the current memory ceiling. Buyers whose systems cannot address 128GB per slot or require a different rank structure cannot use this module.

Questions about this item

What throughput ceiling does the PC4-21300 rating impose on this DDR4 2666 module?

The PC4-21300 designation corresponds to the DDR4 2666 speed grade, giving a theoretical maximum bandwidth of 21300 MB/s.

What physical slot and clearance does this 288-pin LRDIMM require?

It fits a standard 288-pin DDR4 DIMM slot; the module height follows the LRDIMM form factor, so verify your server's DIMM clearance before installing.

What installation step is specific to load-reduced DIMMs like this 8Rx4 module?

Load-reduced DIMMs must be populated according to the server manufacturer's memory population guide; skipping the prescribed slot order is the most common error.
