  • PC4-2133P bus speed enables 2133 MT/s transfer rates
  • Single 32 GB module simplifies capacity upgrades

Server-grade DDR4 DIMM for HP platforms

This HP 752372-081 module delivers 32 GB of DDR4 memory in a single 288-pin DIMM. It is built for server and workstation boards that require registered ECC memory rather than standard desktop UDIMMs. The part is new and carries HP part numbers 774174-001 and 726722-B21 for direct replacement.

PC4-2133P registered ECC specification

The module runs at PC4-2133P with a 4DRx4 organisation, meaning it is a quad-rank registered ECC DIMM. This rank structure and registered buffer are the decisive compatibility factors; systems that accept only single-rank or unbuffered UDIMMs will not post with this part installed.

Steady throughput under sustained workloads

Registered ECC construction corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The quad-rank layout keeps all 32 GB active without rank-switching penalties, so bandwidth remains consistent when the memory controller is saturated for hours.

Questions about this item

What does the PC4-2133P rating mean for real-world server throughput?

The module runs at 2133 MT/s with registered ECC, so sustained bandwidth in a compatible server is limited to the DDR4-2133 data rate rather than higher speeds.

How does the 288-pin DDR4 DIMM interface constrain installation?

The 288-pin registered DIMM only fits server motherboards wired for DDR4 RDIMM slots; it will not seat in desktop UDIMM or SO-DIMM sockets.

What physical clearance does the 32 GB DDR4 DIMM require inside the chassis?

Standard-height DDR4 DIMM profile fits normal server DIMM slots; ensure the motherboard slot spacing and CPU cooler clearance allow a full-height module.
