Server-grade DDR4 RDIMM
This 16GB OWC module is a 288-pin ECC registered DIMM built for servers, workstations and NAS systems. It is not compatible with standard desktop computers and cannot be mixed with unbuffered memory. The part matches Dell part numbers AA579532, AA601617 and AB003152.
Low-voltage JEDEC operation
The module runs at 1.2V with a CL21 latency at 2933MHz PC4-23400. It is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds. No heat spreader is fitted, so airflow in the chassis handles cooling.
Verified OEM replacement
The memory is 100% compliant with JEDEC and RoHS standards for a warranty-safe upgrade. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support. An advanced replacement program is also available.

Questions about this item
How do I install this 288-pin DDR4 RDIMM and what step is often missed?
Align the notch on the module with the slot key, press firmly until both retention clips click, and verify the system BIOS recognises the full 16 GB at 2933 MHz.
What maintenance or replacement will this ECC registered module need over time?
No routine maintenance is required; the module is designed for continuous server operation and carries a limited lifetime warranty, so replacement occurs only if a fault develops.
What limit appears first when this 2Rx8 1.2 V RDIMM runs sustained workloads?
The CAS latency of CL21 at 2933 MHz sets the timing ceiling, and the registered buffer adds one cycle, so sustained throughput is bounded by those fixed timings.
