OWC

OWC 512GB DDR4 2933 ECC Load Reduced 2x256GB Kit Dell R840 R940xa

SKU CH-7HS2-ANKKM

Two 256 GB DDR4 ECC load-reduced DIMMs at 2933 MHz CL21 for Dell PowerEdge R840 and R940xa servers

Capacity 512GB (2 x 256GB)

  • 512 GB total capacity from two 256 GB modules
  • DDR4 2933 MHz CL21 speed rated at PC4-23400
  • ECC load-reduced design for server and workstation reliability
  • 2 V operation with JEDEC and RoHS compliance
  • Backward compatible with 2133, 2400 and 2666 MHz systems

Server-grade memory kit

This OWC kit provides 512GB of DDR4 ECC Load Reduced memory in two 256GB modules. It is built for Dell PowerEdge R840 and R940xa servers and workstations that require registered LRDIMM technology. The kit runs at 2933MHz with a CL21 latency and operates at 1.2V. It is not compatible with standard desktop computers or with unbuffered and registered ECC memory types.

Straightforward module installation

The 288-pin LRDIMMs seat into the server's DIMM slots using standard keyed alignment. Because Load Reduced memory cannot be mixed with unbuffered or registered ECC DIMMs, all existing modules of a different type must be removed first. Populate slots according to the Dell memory population guide for the R840 or R940xa to ensure correct channel interleaving. The kit is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds if the platform requires a lower frequency.

Verify platform and configuration

Confirm the system is a Dell PowerEdge R840 or R940xa and that the BIOS is updated to a version supporting 256GB LRDIMM density. Check the current memory configuration to ensure no unbuffered or registered ECC modules remain installed. Verify the number of available DIMM slots and the maximum supported capacity per socket for your specific CPU configuration. The modules are JEDEC and RoHS compliant for warranty-safe upgrades.

商品問答

How can I confirm the 2933 MHz CL21 modules are running at the correct speed after installation?

Check the BIOS or a system tool such as dmidecode; each 256 GB module should report DDR4 2933 MHz PC4-23400 CL21 at 1.2 V with ECC load-reduced operation.

What is included in the 512 GB kit and do I need any extra parts for a Dell PowerEdge R840 or R940xa?

The kit contains two 256 GB 288-pin DDR4 ECC load-reduced DIMMs; no additional components are required for the listed Dell servers.

Which capacity version should I choose if I want the 512 GB total for my R840 or R940xa?

Select the 512 GB kit, which provides two 256 GB modules for a combined 512 GB of DDR4 2933 ECC load-reduced memory.
