A-Tech 64GB DDR5 5600 ECC RDIMM

This A-Tech module is a 64GB DDR5 5600 registered DIMM with ECC and a Micron chipset. It runs at 1.10V with CL40 latency and a 2Rx4 organisation. The part is built as a compatible replacement for the Micron MTC40F2046S1RC56BD1 and is intended for server and workstation platforms that require registered error-correcting memory.

Suits servers needing registered ECC DDR5

This module fits systems that accept a 288-pin DDR5 RDIMM with ECC and a 2Rx4 rank structure. Builders whose motherboards only support unbuffered UDIMMs or that cannot address a 64GB registered module should look at something else. The 1.10V operating voltage matches the DDR5 baseline, so platforms with different voltage requirements are not compatible.

288-pin DDR5 RDIMM form factor decides fit

The single specification that determines whether this part works is the 288-pin DDR5 registered DIMM form factor combined with ECC and a 2Rx4 layout. If the system’s memory slots and chipset require this exact combination, the module will install and function; if the platform expects a different pin count, buffering type or rank configuration, it will not.

Questions about this item

Does the 64GB DDR5 5600 module ship as a single 288-pin DIMM or must I buy additional sticks?

The listing describes a single 64GB module (1 x 64GB) in a 288-pin DDR5 DIMM form factor, so one stick arrives ready to install.

Should I choose the CL40 1.10V 2Rx4 variant or a different latency or rank for my server?

This unit is specified at CL40, 1.10V and 2Rx4 organisation; select it when your platform requires that exact latency, voltage and rank configuration.

What does the PC5-44800 rating deliver once the RDIMM is seated in a live system?

PC5-44800 indicates a peak transfer rate of 44800 MB/s at 5600 MT/s, giving the registered ECC module its rated bandwidth in compatible server or workstation boards.
