Two green 288-pin DDR4 LRDIMM modules in anti-static packaging

OWC

OWC 512GB (2x256GB) DDR4 3200 CL22 ECC LRDIMM 288-pin 1.2V Memory Upgrade

SKU CH-S5J9-H6HGG

Two 256GB DDR4 3200 CL22 ECC load-reduced LRDIMMs add 512GB of server memory compatible with HP ProLiant DL325, DL345, DL360, DL365 and DL380 Gen10 Plus systems

Capacity 512GB (2 x 256GB)

  • ECC load-reduced design ensures data integrity for critical server workloads
  • 512 GB total capacity across two 256 GB modules expands memory headroom
  • DDR4 3200 MHz CL22 at 1.2 V delivers high throughput with efficient power draw
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz platforms for flexible deployment
  • Validated replacement for HP part numbers P06039-B21, P06039-H21, P06039-K21, P43172-B21, P07654-H21 and P07654-B21

Server ECC LRDIMM Kit

This OWC kit supplies 512GB of DDR4 ECC load-reduced memory as two 256GB modules. It is built for HP ProLiant DL325 Gen10 Plus v2, DL345 Gen10 Plus, DL360 Gen10 Plus, DL365 Gen10 Plus and DL380 Gen10 Plus servers. The modules will not work in standard desktops and cannot be mixed with unbuffered or registered ECC DIMMs.

Thermals Power Noise

Each DIMM operates at 1.2V and runs at the JEDEC-standard DDR4 voltage, keeping power draw low for dense server configurations. Load-reduced architecture reduces electrical loading on the memory bus, which helps maintain signal integrity without additional cooling requirements. The modules produce no audible noise during normal operation.

Deciding Specification

The 288-pin ECC load-reduced form factor with 8Rx4 organisation is the single specification that determines compatibility. Only systems designed for LRDIMM memory at PC4-25600 3200MHz CL22 can use this kit; it replaces HP part numbers P06039-B21, P06039-H21, P06039-K21, P43172-B21, P07654-H21 and P07654-B21.

Questions about this item

How do I install these 288-pin LRDIMMs in my HP ProLiant DL380 Gen10 Plus without mixing memory types?

Power down the server, open the chassis, and insert each 256 GB module into the correct DDR4 slots for your CPU population; the 8Rx4 LRDIMMs must not be mixed with unbuffered or registered ECC DIMMs, so remove any existing sticks of a different type before seating the new pair.

What maintenance or replacement will the 512 GB ECC load-reduced kit need over its service life?

The modules carry a limited lifetime warranty with free technical support; if a stick fails the advanced replacement program ships a replacement before you return the faulty one, and no periodic cleaning or firmware updates are required for the memory itself.

What limit appears first when the 3200 MHz CL22 LRDIMMs run sustained workloads in a DL360 Gen10 Plus?

The CAS latency of 22 cycles at 1.2 V sets the timing boundary; under continuous heavy traffic the memory controller will throttle to the rated 3200 MT/s CL22 profile before any thermal or voltage ceiling is reached.
