Single 256GB DDR4 ECC registered RDIMM module, green PCB with black chips, 288 gold pins

OWC

OWC 256GB DDR4 3200 CL22 ECC Registered RDIMM Memory Upgrade

SKU CH-C1DP-PP42E

A single 256 GB DDR4 3200 CL22 ECC Registered RDIMM module for Supermicro H11SSL and H12SSL motherboards

Capacity 256GB

  • Single 256 GB module doubles server capacity
  • DDR4 3200 CL22 ECC registered ensures data integrity
  • 2 V octal-rank design fits Supermicro H11SSL and H12SSL boards
  • JEDEC and RoHS compliant for reliable long-term operation
  • Validated against Samsung, Hynix and Supermicro part numbers

ECC Registered RDIMM for Supermicro Servers

This single 256GB DDR4 3200 CL22 ECC Registered RDIMM is built for Supermicro motherboards H11SSL-C, H11SSL-i, H11SSW-iN, H11SSW-NT and H12SSL-C. It targets administrators extending the life of existing server infrastructure or building new capacity with validated modules. The octal-rank 8Rx4 design operates at 1.2V and meets JEDEC PC4-25600 specifications.

Verify motherboard model and memory population rules

Before ordering, confirm your board is one of the five listed Supermicro models and that the BIOS revision supports 256GB density per DIMM. This registered ECC module cannot be mixed with unbuffered or load-reduced DIMMs, and all installed DIMMs should match capacity, speed and manufacturer for optimal operation. The 288-pin form factor fits standard DDR4 slots but electrical compatibility is limited to the qualified platforms.

Steady throughput under continuous server workloads

Under sustained load the module maintains its rated 3200 MT/s transfer rate with CL22 latency while ECC corrects single-bit errors in real time. The registered buffer reduces electrical loading on the memory controller, helping stability when all channels are populated at maximum density. JEDEC and RoHS compliance ensures consistent signalling during extended multi-threaded operations typical of virtualization and database tasks.

Points forts

  • Single 256 GB module doubles server capacity
  • DDR4 3200 CL22 ECC registered ensures data integrity
  • 2 V octal-rank design fits Supermicro H11SSL and H12SSL boards
  • JEDEC and RoHS compliant for reliable long-term operation
  • Validated against Samsung, Hynix and Supermicro part numbers

Questions sur cet article

Does the OWC 256GB DDR4 3200 module ship alone or as a kit with multiple sticks?

The upgrade consists of a single 256GB DDR4 3200 PC4-25600 CL22 8Rx4 octal-rank 288-pin 1.2V ECC Registered RDIMM module.

Should I choose this 256GB octal-rank ECC Registered RDIMM or a lower-capacity alternative?

Select this 256GB 8Rx4 module when your Supermicro H11SSL-C, H11SSL-i, H11SSW-iN, H11SSW-NT or H12SSL-C platform supports octal-rank registered DIMMs and you need maximum density per slot.

What does the 3200 PC4-25600 CL22 rating deliver in a live server?

The module runs at 3200 MT/s with a CAS latency of 22 cycles, providing the JEDEC-standard DDR4 bandwidth and timing the listed Supermicro motherboards expect for stable ECC registered operation.
