SKU CH-RHZ8-B5VHQ

Single 256GB DDR4 2933MHz ECC load-reduced DIMM for Dell PowerEdge R840 and R940xa servers

Capacity 256GB

  • Single 256GB module maximises server capacity
  • DDR4 2933MHz CL21 delivers high bandwidth
  • ECC load-reduced design ensures data integrity
  • 2V operation reduces power draw
  • Compatible with Dell PowerEdge R840 and R940xa

Server-grade 256GB DDR4 LRDIMM module

This single 256GB DDR4 2933 CL21 8Rx4 288-pin 1.2V ECC Load Reduced DIMM is built for Dell PowerEdge R840 and R940xa systems. It delivers high-capacity registered memory with error correction for demanding server and workstation workloads.

Suited for administrators expanding compatible

Buyers who need memory for standard desktop PCs or consumer motherboards cannot use this module. It will not work with unbuffered or standard ECC registered DIMMs and cannot be mixed with those types in the same system.

Verify your system accepts 256GB LRDIMM modules

Confirm the server model is exactly R840 or R940xa and that the memory slots support 288-pin ECC Load Reduced DIMMs at 1.2V. Check that existing installed memory is also LRDIMM to avoid mixing incompatible types.

Questions about this item

What server model must I already own for this 256GB DDR4 2933 CL21 8Rx4 288-pin 1.2V ECC LRDIMM to work?

This module is validated for Dell PowerEdge R840 and R940xa servers; it will not function in standard desktops or other platforms.

How does this 2933MHz ECC Load Reduced DIMM behave if I keep existing 2133MHz, 2400MHz or 2666MHz modules in the same server?

It is backward compatible with those slower speeds and will downclock to match the slowest installed module while maintaining ECC load-reduced operation.

How can I verify this 256GB PC4-23400 CL21 1.2V module is running as intended after installation?

Check the server BIOS or management console: it should report 256GB per DIMM, 2933MHz (or the downclocked speed), CL21 timings, 1.2V voltage and ECC Load Reduced status.
