Eight green DDR4 RDIMM modules in silver anti-static tray

OWC

OWC 2TB (8x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM server RAM

SKU CH-V5K2-3PTJV

Eight 256 GB DDR4 3200 ECC registered RDIMMs provide 2 TB of server memory with CL22 latency and 1.2 V operation

Capacity 2TB (8 x 256GB)

  • Massive 2 TB capacity from eight 256 GB modules
  • DDR4 3200 speed with CL22 latency for responsive server workloads
  • ECC registered RDIMM design protects data integrity in critical systems
  • JEDEC and RoHS compliant modules tested in-house for reliability
  • 2 V operation across 288-pin DIMMs reduces power draw per module

OWC 2TB DDR4 3200 Server Kit

This kit provides 2TB of DDR4 3200 ECC Registered memory across eight 256GB RDIMMs. It is built for workstations, servers and NAS systems that require registered DIMMs with error correction. Standard desktop computers cannot use this memory type. Mixing with unbuffered or load-reduced modules is not supported.

Replaces Lower-Capacity Registered DIMMs

The upgrade suits administrators who need to expand memory beyond the limits of smaller registered modules. It is worth installing when the platform supports 256GB octal-rank RDIMMs at DDR4 3200 speeds. Systems restricted to lower densities or slower data rates will not benefit from this kit.

Fits 288-Pin Registered DIMM Slots

Each module uses the 288-pin form factor and operates at 1.2V. The motherboard must provide registered DIMM slots with ECC support and a qualified memory controller for 8Rx4 devices. Using matched modules frees the memory controller from rank-mismatch penalties and simplifies population rules.

Questions about this item

Will these 288-pin RDIMMs fit in a standard 288-pin DDR4 server slot?

Yes, each 256 GB module uses the 288-pin DDR4 RDIMM form factor, so it fits any server board with matching registered DIMM slots.

What is the correct way to populate all eight 8Rx4 modules on a multi-channel board?

Follow the motherboard manual for channel order; a common mistake is mixing these registered DIMMs with unbuffered or load-reduced types, which prevents boot.

How long do the Samsung M393ABG40M52-CAE compatible chips typically last before replacement?

JEDEC-compliant DDR4 RDIMMs are rated for years of continuous server operation; no periodic replacement is required unless a module fails.
