Server-ready 32 GB DDR4 ECC UDIMM

This 32 GB DDR4 2666 MHz module delivers error-correcting unbuffered memory for servers and workstations that require data integrity under continuous workloads. It operates at the standard 1.2 V and uses a 2Rx8 rank configuration with CL19 latency. The 288-pin DIMM fits platforms designed for DDR4 ECC UDIMM memory.

Replaces Dell AA101754 and AA335284 modules

The part is a direct equivalent for Dell part numbers AA101754 and AA335284, making it a drop-in upgrade for compatible Dell servers and workstations. The jump is worth it when your system currently runs lower-capacity or non-ECC modules and you need the extra 32 GB per slot with error correction for virtualization, databases or large datasets. Systems that do not support ECC UDIMM or that require registered DIMMs cannot use this module.

Simple DIMM installation with standard precautions

Installation follows the usual DIMM procedure: power down, open the chassis, align the 288-pin key notch, and press firmly until the retention clips lock. What usually goes wrong is mixing ECC UDIMM with registered or non-ECC modules, exceeding the platform's maximum per-slot capacity, or leaving the module partially seated. Verify the supported memory specifications of your system before purchase to ensure compatibility.

Questions about this item

Does this module fit a standard 288-pin DDR4 UDIMM slot?

Yes, it is a 288-pin DDR4 DIMM designed for unbuffered ECC slots in servers and workstations.

Do I need to enable ECC in the BIOS after installing this CL19 2Rx8 stick?

Install the module, then enter BIOS to verify ECC is active; some systems default it to disabled.

Will the major-brand chips on this 1.2 V module need active cooling later?

Standard server airflow is sufficient; no extra cooling is required for 1.2 V DDR4 operation.
