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

SKU CH-2FE2-1E7XS

A 256 GB DDR4 3200 ECC registered RDIMM with CL22 latency and 1.2 V operation for server upgrades

Capacity 256GB

  • 256 GB capacity supports large server workloads
  • DDR4 3200 PC4-25600 speed delivers high throughput
  • CL22 1.2 V ECC registered ensures data integrity
  • 8Rx4 octal-rank 288-pin design fits dense configurations
  • JEDEC and RoHS compliant for warranty-safe upgrades

256 GB DDR4-3200 registered server memory

This 256 GB DDR4 module runs at 3200 MT/s with PC4-25600 bandwidth and CL22 latency. It uses an 8Rx4 octal-rank layout on a 288-pin RDIMM operating at 1.2 V. ECC registered architecture targets enterprise workloads that require error correction and signal buffering.

Suited for servers and workstations needing

Buyers who need unbuffered desktop memory cannot use this module. Systems that require load-reduced ECC DIMMs are also incompatible. Mixing this registered part with either unbuffered or load-reduced memory will prevent correct operation.

JEDEC and RoHS compliant DDR4 specification

The module meets JEDEC DDR4 standards and RoHS requirements for a warranty-safe upgrade. It is validated as a direct replacement for Hynix part numbers HMAT14JXSRB120N and HMAT14JXSRB122N. Verify that your platform supports 256 GB registered RDIMMs before purchasing.

Questions about this item

How do I install this 288-pin RDIMM and what step is often missed?

Align the notch on the 288-pin module with the server DIMM slot key, press firmly until both retention clips click, and verify the motherboard sees the full 256 GB per module at 3200 MT/s.

What maintenance or replacement will this ECC Registered module need later?

No scheduled maintenance is required; if a correctable error count climbs or the module fails POST, replace the individual 256 GB RDIMM — matched capacity and speed are recommended.

What limit appears first under sustained load with this CL22 1.2 V kit?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor, so sustained throughput is bounded by the JEDEC-standard CL22 specification.
