Single green 288-pin DDR4 LRDIMM module with black chips

OWC

OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC LRDIMM memory upgrade

SKU CH-B2PD-A2MZ2

A single 256 GB DDR4 3200 ECC load-reduced DIMM for Dell PowerEdge XR11 and XR12 servers

Capacity 256GB

  • 256 GB capacity in a single module expands server memory density
  • DDR4 3200 MHz CL22 speed handles demanding workloads efficiently
  • ECC load-reduced design maintains data integrity under heavy use
  • 2 V operation reduces power draw per installed module
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

256GB DDR4-3200 ECC Load-Reduced DIMM

This single 256GB DDR4 module runs at 3200MHz with CL22 latency and operates at 1.2V. It uses a 288-pin ECC load-reduced form factor built to JEDEC PC4-25600 specifications for server and workstation platforms. The module is validated for Dell PowerEdge XR11 and XR12 systems.

Suited for server and workstation upgrades only

This memory is designed for servers, workstations and NAS systems that accept ECC load-reduced DIMMs. It will not work in standard desktop computers and cannot be mixed with unbuffered or ECC registered modules. Buyers needing memory for consumer PCs or laptops should look elsewhere.

256GB capacity with DDR4-2133 to 3200 headroom

The 256GB density provides substantial capacity for memory-intensive server workloads and virtualization. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so the module can slot into older DDR4 platforms. Systems requiring higher frequencies or different ECC types will not be supported.

Soalan tentang produk ini

What motherboard slot and memory type are required to install this 288-pin DDR4 LRDIMM?

A server or workstation motherboard with DDR4 288-pin LRDIMM slots that support ECC load-reduced modules at 1.2V.

Can this 3200MHz PC4-25600 module run with existing 2666MHz or 2933MHz DDR4 LRDIMMs in the same system?

Yes, it is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, but all modules must be ECC load-reduced type.

How do I verify the module is detected at 256GB capacity and 3200MHz CL22 after installation?

Check the system BIOS or UEFI memory information screen; it should show 256GB per module at PC4-25600 3200MHz with CL22 timings.
