Two green 288-pin DDR4 LRDIMM modules with black chips and gold contacts

OWC

OWC 512GB (2x256GB) DDR4 3200 CL22 ECC Load Reduced LRDIMM memory upgrade

SKU CH-DJYW-0C4ET

Kit of two 256 GB DDR4 3200 CL22 ECC load-reduced LRDIMMs totalling 512 GB for Dell PowerEdge MX750c, R650 and R750 servers

Capacity 512GB (2 x 256GB)

  • 512 GB capacity from two 256 GB modules
  • DDR4 3200 CL22 ECC load-reduced for server reliability
  • JEDEC and RoHS compliant warranty-safe upgrade
  • Backward compatible with 2133 2400 2666 2933 MHz systems
  • Validated for Dell PowerEdge MX750c R650 R750 servers

Server memory upgrade kit

This kit supplies 512 GB of DDR4 memory across two 256 GB modules rated at 3200 MHz CL22. It is built for Dell PowerEdge MX750c, R650 and R750 servers that require ECC load-reduced DIMMs. The modules run at 1.2 V and use the 288-pin form factor. This product is not for desktop PCs or any system that takes unbuffered or registered ECC memory.

Interface limits and backward compatibility

The DDR4 modules operate at the PC4-25600 3200 MHz standard and will also run at 2133, 2400, 2666 and 2933 MHz when the platform requires a lower speed. They cannot be mixed with unbuffered or registered ECC DIMMs, so the entire memory population must use the same load-reduced technology. JEDEC and RoHS compliance ensures the kit meets the electrical and environmental rules for server deployment.

Decisive specification

The critical detail is the ECC load-reduced 8Rx4 organisation; only systems designed for this exact memory type will accept the modules. Buyers who need standard desktop memory or a different ECC variant cannot use this kit. Confirm the server model and memory architecture before purchase.

Questions about this item

Should I pick the 512GB kit or buy single 256GB modules to reach the same total?

The kit already contains two matched 256GB modules for a 512GB total, so you install both at once and avoid mixing separate sticks.

What does the 3200MHz CL22 rating actually deliver in a Dell PowerEdge R650 or R750?

The modules run at 3200MHz with CL22 latency at 1.2V, and the server’s memory controller will set the final speed up to that ceiling.

How does the DDR4 LRDIMM interface limit performance compared with standard RDIMMs?

LRDIMM buffers the load on each rank, letting the 8Rx4 organisation reach 3200MHz while keeping the electrical load within the platform’s limits.
