128GB DDR4 3200 ECC LRDIMM

This A-Tech server memory module delivers 128GB of DDR4 capacity at 3200MHz with PC4-25600 bandwidth. It operates at 1.20V with CL22 latency and uses a 288-pin DIMM form factor. The load-reduced design includes ECC for data integrity in mission-critical environments.

Suited for HP/HPE server upgrades

Administrators replacing part numbers P11057-0A1, P19402-001, P18454-B21, P07652-B21, P07652-H21, P06037-B21, P06037-H21, or P06037-K21 will find direct compatibility. Systems requiring unbuffered UDIMMs or standard registered RDIMMs cannot use this load-reduced module. Buyers needing smaller capacities or non-ECC memory should look elsewhere.

Fits DDR4 LRDIMM server slots

The single 128GB module occupies one 288-pin DDR4 slot and draws standard 1.20V power. Its 4DRx4/4Rx4 rank structure allows high density without increasing electrical load on the memory controller. This frees additional DIMM slots for further expansion while maintaining signal integrity at 3200MHz speeds.

Highlights

  • 128GB capacity handles demanding server workloads
  • DDR4 3200MHz speed accelerates data throughput
  • ECC LRDIMM technology protects data integrity under load
  • 2V operation reduces power consumption per module
  • Compatible replacement for multiple HP part numbers

Questions about this item

Does my server need to support DDR4 3200 ECC LRDIMM to use this 128GB module?

Yes, the system must accept DDR4 3200 (PC4-25600) ECC Load Reduced DIMMs at 1.2V with a 288-pin interface for this module to function.

Can I mix this 4Rx4 LRDIMM with existing 2Rx4 RDIMMs in the same HPE server?

No, Load Reduced and Registered DIMMs cannot be mixed in the same memory channel or processor socket; all slots must use the same LRDIMM type.

How can I verify the module is running at 3200 MT/s with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode; it should report 3200 MT/s, ECC enabled, and the correct 128GB capacity per module.
