Single green 288-pin DDR4 RDIMM module with black chips and gold contacts

OWC

OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM memory upgrade

SKU CH-MJRH-NP1XQ

256 GB DDR4 3200 ECC registered RDIMM for Dell PowerEdge MX750c, R650 and R750 servers

Capacity 256GB

  • Massive 256GB capacity in a single module
  • ECC registered design protects data integrity in servers
  • DDR4-3200 speed with CL22 latency for responsive performance
  • Low 1.2V operation reduces power draw and heat
  • Validated for Dell PowerEdge MX750c R650 R750 systems

Server-grade ECC RDIMM

This single 256 GB DDR4 module runs at 3200 MT/s with CL22 latency and operates at 1.2 V. It uses an octal-rank 8Rx4 layout on a 288-pin registered DIMM and is built specifically for Dell PowerEdge MX750c, R650 and R750 servers.

Registered design and compatibility

The registered buffer and ECC circuitry make this memory suitable only for workstation and server platforms that support registered RDIMMs. It cannot be mixed with unbuffered or load-reduced DIMMs, and it will not function in standard desktop motherboards.

JEDEC DDR4 limits

The module conforms to JEDEC PC4-25600 specifications, so its speed and voltage are fixed by that standard. Capacity scaling beyond 256 GB per DIMM would require a different memory technology not covered by the DDR4 specification.

Points forts

  • Massive 256GB capacity in a single module
  • ECC registered design protects data integrity in servers
  • DDR4-3200 speed with CL22 latency for responsive performance
  • Low 1.2V operation reduces power draw and heat
  • Validated for Dell PowerEdge MX750c R650 R750 systems

Questions sur cet article

What bandwidth does the DDR4-3200 PC4-25600 interface provide for this module?

The DDR4-3200 PC4-25600 interface delivers up to 25,600 MB/s of peak bandwidth for this 256GB module.

What physical slot and form factor does this 288-pin RDIMM require?

This 288-pin ECC Registered RDIMM fits a standard DDR4 DIMM slot on Dell PowerEdge MX750c, R650 and R750 motherboards.

How is this module installed and which population rule is often missed?

Insert the RDIMM into the correct DDR4 slot until the ejectors click; all DIMMs must match in capacity, speed and manufacturer for optimal performance.
