OWC 64GB DDR4 2933MHz ECC Registered RDIMM 2Rx4 1.2V for Dell AA579530 AA601615 AB003154 Server RAM

SKU CH-Y218-1PBKP

A 64 GB DDR4 2933 MHz ECC registered RDIMM with CL21 latency and 1.2 V operation for Dell-compatible servers

  • Capacity64GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes
  • 64GB capacity expands server memory for larger workloads
  • DDR4 2933MHz speed with CL21 latency delivers responsive data throughput
  • ECC registered design detects and corrects errors for reliable operation
  • 2V low voltage reduces power draw and heat output
  • Backward compatible with 2133MHz 2400MHz 2666MHz systems for flexible deployment

Dell-Compatible 64GB ECC RDIMM

This 64GB DDR4 2933MHz ECC Registered RDIMM matches Dell part numbers AA579530, AA601615 and AB003154. It is built for servers, workstations and NAS systems that require registered memory with error correction. Standard desktop computers cannot use this module, and it must not be mixed with unbuffered memory.

Capacity and Speed Headroom

The single module provides 64GB at PC4-23400 with CL21 latency and 1.2V operation. It runs at 2933MHz and will also operate in systems rated for 2133MHz, 2400MHz or 2666MHz. Workloads that exceed 64GB per slot or need faster than 2933MHz will require additional modules or a platform that supports higher speeds.

JEDEC Compliance and Warranty

The module meets JEDEC-standard specifications and is ROHS compliant, ensuring a warranty-safe upgrade for OEM systems. OWC backs it with a limited lifetime warranty and free technical support, plus an advanced replacement program that reduces downtime if a fault occurs.

Questions about this item

Will this 2933MHz DDR4 RDIMM run reliably alongside my existing 2400MHz ECC registered modules?

Yes, the module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 ECC registered DIMMs, so it will operate at the speed of the slowest installed kit.

How can I confirm the 64GB stick is detected at 2933MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 64GB, DDR4-2933, CL21, 1.2V and ECC registered status.

Does the single 2Rx4 RDIMM ship with any heat spreader, bracket or extra cables I might need?

No, the module has no heat spreader and the package contains only the 288-pin DDR4 ECC registered DIMM itself.
