OWC 64GB DDR4 3200 ECC Registered RDIMM CL22 1.2V 2Rx4 288-pin server RAM

SKU CH-A5PS-NYFX8

64 GB DDR4 3200 ECC registered RDIMM for servers, workstations and NAS systems with CL22 latency and 1.2 V operation

  • CAS latency22
  • Rated voltage1.2 V
  • Buffer typeRegistered
  • Product type288-Pin DDR4 ECC RDIMM
  • 64 GB capacity handles heavy server workloads
  • DDR4 3200 MHz speed with CL22 latency
  • ECC registered design protects data integrity
  • 2 V operation reduces power draw
  • Backward compatible with 2133, 2400, 2666, 2933 MHz systems

Server memory upgrade for Dell systems

This OWC 64GB DDR4 3200 ECC registered RDIMM replaces the Dell AA783423 module in compatible servers and workstations. It delivers PC4-25600 speed at CL22 latency with 1.2V operation. The single 2Rx4 288-pin module adds 64GB of error-correcting capacity per slot.

Upgrade from lower-capacity or slower DDR4 RDIMMs

The jump is worthwhile when your workload needs more than 32GB per channel or when replacing 2133MHz, 2400MHz, 2666MHz or 2933MHz modules with the 3200MHz JEDEC-standard part. Backward compatibility lets you mix speeds while the system runs at the lowest installed frequency.

Suits IT teams extending server life

Buyers who need unbuffered desktop memory or load-reduced ECC DIMMs cannot use this registered module. Systems that require registered ECC RDIMMs in 288-pin DDR4 form factor will accept this upgrade.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 RDIMM form factor and runs at 1.2V. It fits any server, workstation or NAS system that accepts registered ECC DDR4 DIMMs.

What is the correct way to install this registered ECC module, and what mistake should I avoid?

Power down the system, open the chassis, align the notch on the 288-pin edge connector with the slot key, and press firmly until both retention clips click. Do not mix this registered DIMM with unbuffered or load-reduced ECC memory.

When will this 64GB DDR4 module need replacement or maintenance?

The memory has no moving parts and requires no routine maintenance. It carries a limited lifetime warranty, so replacement would only be needed if a module fails or if you later upgrade to a higher capacity or newer DDR generation.
