Four green DDR4 RDIMM modules with gold contacts and black chips in a row

OWC

OWC 1TB (4×256GB) DDR4 3200 CL22 ECC Registered RDIMM memory upgrade

SKU CH-WPGN-DHG3T

1TB kit of four 256GB DDR4 3200 ECC registered RDIMMs for Dell PowerEdge MX750c, R650 and R750 servers

Capacity 1TB (4 x 256GB)

  • ECC registered design prevents data errors in servers
  • 1TB kit with four 256GB modules maximises capacity
  • DDR4 3200 CL22 timing balances speed and latency
  • 2V operation reduces power draw in dense configs
  • Validated for Dell PowerEdge MX750c R650 R750

Server-Specific ECC Registered Upgrade

This kit provides 1TB of DDR4 3200 ECC Registered memory in four 256GB RDIMM modules. It is built for Dell PowerEdge MX750c, R650 and R750 servers that require registered error-correcting DIMMs. Standard desktop motherboards cannot use this memory type and it must not be mixed with unbuffered or load-reduced modules.

Octal-Rank 8Rx4 Architecture Decides Fit

Each module uses an 8Rx4 octal-rank organisation with CL22 timing at 1.2V. The server memory controller must support this rank density and registered signalling; otherwise the system will not POST or will recognise only a fraction of the capacity. Verify the platform's qualified-vendor list before purchase.

Cross-Referenced Part Numbers Simplify Validation

The kit matches Samsung M393ABG40M52-CAE, Hynix HMAT14JXSRB120N and HMAT14JXSRB122N, and Supermicro MEM-DR425MI-ER32. Buyers can confirm compatibility against existing inventory or vendor documentation without guessing. No additional software or accessories are included.

Questions about this item

What does the 3200 MT/s speed mean for my Dell PowerEdge R750?

The modules run at 3200 MT/s (PC4-25600) with CL22 latency, delivering the rated bandwidth when installed in supported Dell PowerEdge MX750c, R650 or R750 servers.

How does the DDR4 ECC Registered RDIMM interface affect compatibility?

These are 288-pin DDR4 ECC Registered RDIMMs (8Rx4, 1.2 V). They only work in servers that support registered ECC memory and cannot be mixed with unbuffered or load-reduced DIMMs.

Will the 256 GB modules fit in the memory slots of a Dell PowerEdge MX750c?

Each module is a standard 288-pin DDR4 RDIMM. The kit includes four 256 GB sticks designed for the MX750c, R650 and R750 memory slots.
