Two green 288-pin DDR4 LRDIMM sticks in anti-static tray

OWC

OWC 512GB (2x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade

SKU CH-NMQZ-QC07E

Dual 256 GB DDR4 3200 ECC load-reduced LRDIMM kit adds 512 GB to Cisco UCS C240 M6 and C245 M6 servers

Capacity 512GB (2 x 256GB)

  • 512 GB total capacity from two 256 GB modules
  • DDR4 3200 MHz CL22 for high-speed server workloads
  • ECC load-reduced design protects data integrity
  • 2 V operation reduces power draw in dense configs
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

512 GB ECC LRDIMM kit for Cisco UCS servers

This kit delivers 512 GB of DDR4 3200 memory in two 256 GB load-reduced DIMMs. It is built for Cisco UCS C240 M6 and C245 M6 servers that require ECC LRDIMM modules. The memory operates at 1.2 V with CL22 latency and uses the 288-pin form factor. Standard desktop systems cannot use this memory type.

Capacity headroom at 3200 MT/s

The 512 GB total lets memory-intensive workloads such as virtualisation, large databases and in-memory analytics run without swapping. Each 256 GB module is an 8Rx4 device, so the platform must support that rank configuration. The kit also runs at 2133, 2400, 2666 and 2933 MT/s when the server bus speed is lower, giving flexibility across mixed environments.

Replaces lower-capacity or slower LRDIMM sets

Upgrading from smaller LRDIMM kits or slower DDR4 speeds is worthwhile when the application hits capacity limits or memory bandwidth bottlenecks. The jump makes sense for Cisco UCS C240 M6 and C245 M6 owners who need the maximum supported density per slot. It is not for systems that only accept unbuffered or registered ECC DIMMs, nor for platforms limited to lower per-slot capacities.

Questions about this item

Will the 3200 MHz PC4-25600 modules run with the 2666 MHz DDR4 already in my Cisco UCS C240 M6?

The kit is backward compatible with 2133, 2400, 2666 and 2933 MHz speeds, so it will operate at the speed of your existing DDR4 modules.

How can I confirm the 512 GB ECC Load Reduced kit is recognised after installation?

Check the Cisco UCS BIOS or the OS memory report; both should show 512 GB total capacity with ECC Load Reduced type and the correct 3200 MHz speed.

What does the 2x256 GB kit contain and is anything else required?

The package includes two 256 GB 288-pin DDR4 ECC Load Reduced DIMMs; no additional cables, brackets or tools are needed for installation.
