Single green 288-pin LRDIMM module with black memory chips

OWC

OWC 256GB DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC LRDIMM memory upgrade

SKU CH-0V9Z-F9NS4

Single 256GB DDR4 3200 CL22 ECC LRDIMM for compatible Supermicro server and workstation boards

Capacity 256GB

  • 256GB single module maximises server capacity
  • ECC load-reduced design ensures data integrity for workloads
  • DDR4 3200 CL22 at 1.2V balances speed with efficiency
  • 288-pin LRDIMM fits Supermicro H12SSL and H12SSW boards
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

Server-grade capacity upgrade

This 256GB DDR4 LRDIMM module targets administrators expanding Supermicro H12SSL or H12SSW platforms. It delivers a single-stick density that lets dense memory configurations stay within limited slot counts. The ECC load-reduced design is mandatory for these boards and will not operate in standard desktop systems.

3200 MHz speed with broad backward support

Rated at PC4-25600 CL22, the module runs at 3200 MHz and drops cleanly to 2133, 2400, 2666 or 2933 MHz when the memory controller requires it. Capacity headroom suits virtualisation hosts and large in-memory databases, while the fixed 1.2 V operation keeps power draw predictable per DIMM slot.

JEDEC-compliant 288-pin build quality

The 288-pin LRDIMM form factor seats directly in registered DIMM slots on the qualified Supermicro motherboards. JEDEC and RoHS compliance ensures electrical parity with OEM modules, and the load-reduced buffer reduces electrical loading on the memory bus for stable operation across fully populated channels.

Questions about this item

Will this 256GB DDR4 3200 CL22 8Rx4 LRDIMM run alongside my existing 2666MHz ECC load-reduced modules?

Yes. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so it will operate at the speed of the slowest installed DIMM.

How can I verify the 256GB DDR4 3200 PC4-25600 CL22 module is detected correctly after installation?

Check the system BIOS or UEFI memory configuration screen; it should report a single 256GB DIMM running at 3200MHz with CL22 timings and ECC load-reduced status.

Does the 256GB DDR4 3200 CL22 288-pin 1.2V ECC LRDIMM ship alone, or are extra parts included?

The upgrade consists of a single 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC load-reduced DIMM; no cables, brackets or additional components are supplied.
