64GB DDR4 3200 ECC RDIMM

This A-Tech server memory module provides 64GB of DDR4 3200 capacity in a single 288-pin registered DIMM. It operates at 1.20V with CL22 latency and uses a 2Rx4 organisation with ECC for error correction. The stick is built with major-brand chips and tested for dependable operation in server and workstation platforms.

Suited for Dell systems needing registered ECC

The module matches Dell part numbers including 370-AELJ, 370-AEVP, AA783423, AA799110, AA810828, AB214253, P2MYX, SNPP2MYXC/64G and SNPP2MYXC/64VXR. It is not for desktop boards that accept only unbuffered non-ECC DIMMs, nor for platforms limited to lower densities or speeds.

Simple DIMM installation with compatibility checks

Insert the 288-pin module into a DDR4 RDIMM slot and ensure the platform supports registered ECC memory at this density and speed. The usual issue is a motherboard that rejects registered DIMMs or cannot address a 64GB single rank configuration, so verify the system’s qualified vendor list before fitting.

Questions about this item

Does this 288-pin DDR4 RDIMM need a server motherboard with registered DIMM slots to work?

Yes, the module is an ECC registered DIMM built for server and workstation platforms that support registered memory.

Can this CL22 3200 MHz stick run in a system that currently uses Dell 370-AELJ or 370-AEVP modules?

It is listed as a compatible equivalent for those Dell part numbers, so it can replace or join them in supported configurations.

How do I confirm the module is detected at 64 GB with ECC active after installation?

Check the BIOS memory summary or operating-system hardware report for 64 GB capacity and ECC status showing enabled.
