OWC 256GB DDR4 3200 CL22 ECC LRDIMM 288-pin Server RAM

SKU CH-J0MF-GF86A

256 GB DDR4 3200 CL22 ECC load-reduced 288-pin DIMM for servers, workstations and NAS, backward compatible to 2133, 2400, 2666 and 2933 MHz

  • 256GB capacity lets servers handle massive workloads
  • DDR4 3200MHz CL22 speed delivers high-throughput data processing
  • ECC load-reduced design maintains signal integrity at scale
  • 2V operation reduces power draw per module
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

Server memory upgrade for HP systems

This 256 GB DDR4 LRDIMM replaces HP part numbers P06039B21, P06039H21, P06039K21, P07654B21 and P07654B21. It is built for servers, workstations and NAS systems that require ECC load-reduced modules. The kit is not compatible with standard desktop computers or with unbuffered and registered ECC memory types.

JEDEC and RoHS compliance changes the support

The module meets JEDEC standards and RoHS requirements, making it a warranty-safe upgrade for OEM platforms. An advanced replacement programme and limited lifetime warranty with free technical support are included by the manufacturer. These services change the ownership experience without altering the hardware specifications.

3200 MHz CL22 speed rating decides fit

The module runs at PC4-25600 3200 MHz with a CAS latency of 22 at 1.2 V. Backward compatibility covers 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz bus speeds. Buyers needing a different frequency, latency or voltage must select another part.

Questions about this item

Will the 8Rx4 ECC Load Reduced DIMM need firmware updates or battery-backed components replaced over time?

The module has no battery or firmware; it is a passive DRAM DIMM. ECC corrects single-bit errors on the fly, and the only replacement trigger is an uncorrectable multi-bit failure detected by the server.

What thermal or electrical limit appears first when the 256 GB LRDIMM runs continuously at 3200 MHz CL22?

The 1.2 V JEDEC voltage ceiling is reached before any thermal throttle; sustained loads stay within spec as long as chassis airflow meets the server vendor's guidelines.

How much additional heat and power does a single 256 GB LRDIMM add compared with a standard 32 GB RDIMM in a 24-slot chassis?

Each module draws roughly 1.2 V at its rated current; total power scales with capacity and rank count, so eight 256 GB LRDIMMs consume noticeably more than 32 GB RDIMMs, but the 1.2 V rail remains the design limit.
