Four green DDR4 RDIMM sticks with black chips and gold contacts

OWC

OWC 1TB (4x256GB) DDR4 3200 CL22 8Rx4 ECC Registered RDIMM server RAM

SKU CH-E1FC-2BZEF

Kit of four 256 GB DDR4-3200 ECC registered RDIMMs adding 1 TB capacity for servers

Capacity 1TB (4 x 256GB)

  • ECC registered design protects data integrity in servers
  • 3200 MT/s DDR4 speed accelerates memory-bound workloads
  • Four 256 GB modules deliver 1 TB total capacity
  • 288-pin 1.2 V RDIMM fits standard server DIMM slots
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server ECC Registered Memory Upgrade

This OWC kit provides 1 TB of DDR4 server memory across four 256 GB modules. It is built for workstations and servers that require ECC Registered RDIMMs. Standard desktop computers cannot use this memory type. Mixing with unbuffered or load-reduced DIMMs is not supported.

Octal-Rank 8Rx4 Module Configuration

Each 288-pin DIMM uses an 8Rx4 octal-rank layout and runs at 3200 MT/s with CL22 latency at 1.2 V. The PC4-25600 rating matches the Samsung M393ABG40M52-CAE part it replaces. JEDEC and RoHS compliance ensures warranty-safe operation in qualified platforms.

Straightforward DIMM Installation

Install by seating each module into the server's 288-pin slots until the retention clips lock. The main risk is attempting to use these Registered DIMMs in a desktop board or mixing them with incompatible memory types, which will prevent the system from booting. Verify the platform supports ECC Registered RDIMMs before purchase.

Questions sur cet article

What does the 3200 figure mean once the modules are installed in a server?

The modules run at a 3200 MT/s data rate, which the memory controller treats as PC4-25600 bandwidth.

Which interface standard do the 288-pin modules use, and what does it cap in practice?

They use the DDR4 JEDEC standard, limiting operation to the 1.2 V voltage and 3200 MT/s speed defined by that specification.

What physical slot and clearance do the 288-pin RDIMMs need to fit?

Each module requires a standard 288-pin DDR4 DIMM socket; the registered design adds a buffer chip, so verify the motherboard supports registered RDIMMs and that the slot spacing accommodates four modules.
