Single green 288-pin DDR4 LRDIMM module with black memory chips

OWC

OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin ECC Load Reduced LRDIMM memory upgrade

SKU CH-91D2-F1SVA

Single 256 GB DDR4 3200 ECC load-reduced DIMM for servers, workstations and NAS systems, backward compatible with 2133, 2400, 2666 and 2933 MHz speeds

Capacity 256GB

  • Single 256 GB module expands server capacity
  • DDR4 3200 MHz CL22 delivers high bandwidth
  • ECC load-reduced design protects data integrity
  • 2 V operation lowers power draw
  • Backward compatible with 2133, 2400, 2666, 2933 MHz systems

Server memory upgrade

This OWC module is a 256GB DDR4 3200 PC4-25600 CL22 ECC load-reduced DIMM built for Gigabyte MP72-HB0, MU72-SU0, MU92-TU1, MZ01-CE0 and MZ01-CE1 systems. It targets server, workstation and NAS operators who need maximum single-slot capacity without mixing memory types.

Compatibility check

Verify your platform accepts 288-pin DDR4 ECC load-reduced memory and cannot mix this module with unbuffered or registered ECC DIMMs. The part runs at 1.2V and is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds, so the motherboard must support one of those rates.

Build and connectors

The 288-pin LRDIMM form factor fits standard server DIMM slots and uses JEDEC-standard pin-outs for reliable seating. ECC load-reduced architecture reduces electrical load on the memory controller, helping maintain signal integrity in dense configurations while the 1.2V operation keeps power draw consistent across supported speeds.

Questions about this item

Does the 256GB LRDIMM ship as a single module or a kit, and are any additional parts required?

The upgrade consists of one 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced DIMM. No extra components are needed for installation.

Which capacity or rank option should I select for a Gigabyte MP72-HB0 server?

This listing provides a single 256GB 8Rx4 module validated for the MP72-HB0, MU72-SU0, MU92-TU1, MZ01-CE0 and MZ01-CE1 platforms.

What does the 3200MHz CL22 rating deliver when the module runs in a compatible server?

The module operates at 3200MHz with CL22 latency and will down-clock to 2133MHz, 2400MHz, 2666MHz or 2933MHz if the system requires a lower speed.
