Server-specific DDR4 LRDIMM kit

This OWC kit supplies 256GB of DDR4 ECC Load Reduced memory in two 128GB modules. It is built for Dell PowerEdge R6525, R750xa and R7525 servers that require registered LRDIMM technology. The modules run at 3200MHz with a CAS latency of CL22 and operate at 1.2V. This memory is not compatible with standard desktop computers or consumer motherboards.

Verify LRDIMM requirement and slot count

Before ordering, confirm that your server platform supports DDR4 ECC Load Reduced DIMMs and cannot accept unbuffered or standard registered ECC modules. The kit occupies two 288-pin DIMM slots, so ensure the target system has at least two free slots of the correct type. Mixing this LRDIMM kit with other memory types will prevent the system from booting.

Adds 256GB to supported PowerEdge servers

When installed in a compatible Dell PowerEdge R6525, R750xa or R7525, the kit adds 256GB of error-correcting capacity for virtualisation, database or compute workloads. The modules are backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds. JEDEC-standard construction ensures a warranty-safe upgrade without requiring changes to the existing power or cooling infrastructure.

Soalan tentang produk ini

What comes in the OWC 256GB DDR4 3200 LRDIMM kit and is anything else needed?

The kit includes two 128GB DDR4 3200 CL22 4Rx4 288-pin 1.2V ECC load-reduced DIMMs. No additional parts are required for installation in a compatible Dell PowerEdge server.

Which capacity version should I choose for a Dell PowerEdge R7525?

This 256GB kit (2×128GB) is the capacity offered for the R7525, R6525 and R750xa. Select it when you need 256GB of ECC load-reduced memory across two DIMM slots.

What does the 3200 CL22 rating mean once the modules are installed in a PowerEdge R6525?

The modules will run at up to 3200 MT/s with CAS latency 22 at 1.2V. They also down-clock automatically to 2933, 2666, 2400 or 2133 MT/s if the server requires a lower speed.
