Target system fit

This 16GB DDR4 2666 ECC RDIMM module is built for Dell servers and workstations that require registered, error-correcting memory. It replaces part numbers AA153023, AA546831, DFK3Y, PWR5T, SNPDFK3YC/16G and XMP93 in compatible platforms. The single 288-pin DIMM delivers 16GB capacity at CL19 latency and 1.20V operation.

Upgrade scope

It upgrades systems running lower-capacity or non-ECC DDR4 modules where registered memory is mandatory. The jump is worth it when workloads demand data integrity and the motherboard supports RDIMM population rules. Buyers who need unbuffered UDIMMs or higher frequencies cannot use this module.

Sustained behaviour

Registered buffering and ECC correction maintain signal integrity and error detection during continuous multi-threaded server loads. Major-brand chips are tested to sustain the rated 2666MHz PC4-21300 throughput without throttling. The 2Rx8 organisation supports dense memory configurations typical of virtualisation hosts.

Questions sur cet article

Will the 288-pin DDR4 DIMM fit my Dell server memory slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor required by Dell servers that accept AA153023 or AA546831 part numbers.

Do I need to install this registered ECC module in specific slot pairs or channels?

Install the RDIMM in the same channel configuration as your existing memory; the common mistake is mixing registered and unbuffered DIMMs in the same system.

When should I consider replacing this 16GB ECC RDIMM?

Replace the module if system diagnostics report correctable ECC errors that increase over time or if the server fails memory self-test during POST.
