Server memory upgrade

This 32GB DDR4 2933MHz ECC registered RDIMM is built for Dell servers and workstations that require part numbers 8WKDY, AA579531 or AB003153. The module delivers 32GB capacity at PC4-23400 speed with CL21 latency and 1.2V operation. It targets administrators extending the life of existing infrastructure or building new server deployments.

Compatibility check

Verify that your system accepts 288-pin DDR4 ECC registered DIMMs and supports 2Rx4 rank configuration. This memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. The platform must also support DDR4 2933MHz or one of the backward compatible speeds of 2133MHz, 2400MHz or 2666MHz.

What the bundle changes

The module arrives as a single 32GB stick with no heat spreader, ready for direct installation in compatible slots. JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. OWC provides a limited lifetime warranty with free technical support and an advanced replacement program for the product.
