A-Tech 128GB DDR5 6400MHz ECC RDIMM

This A-Tech module provides 128GB of DDR5 registered ECC memory for server and workstation platforms. It operates at 6400MHz with a CAS latency of 32 and runs at the standard 1.1V. The 288-pin RDIMM uses Samsung chipset components in a 2Rx4 configuration without a heat spreader.

Suited for DDR5 servers needing registered ECC

This module fits systems that require DDR5 RDIMM modules with ECC error correction and registered buffering. Builders whose platforms only accept unbuffered UDIMMs or non-ECC memory cannot use this part. It is also unsuitable for any board limited to earlier DDR generations or a different pin count.

The registered ECC RDIMM form factor decides

The module is a 288-pin DDR5 RDIMM with on-board register and ECC circuitry; the motherboard must explicitly support registered ECC DIMMs. Verify the system manual for DDR5 RDIMM qualification, supported ranks, and channel population rules before purchase.

Preguntas sobre este artículo

What is the CAS latency of this 128GB DDR5 6400MHz ECC RDIMM module?

The module runs at CAS latency 32, which is the standard timing for DDR5-6400 registered memory.

How much power does the module draw and does it generate much heat during continuous server workloads?

Operating at 1.10V with no heat spreader, it uses the standard DDR5 voltage; registered buffering keeps signal integrity stable under sustained load.

Which motherboard slot and chipset support are needed for this 288-pin RDIMM to function?

It requires a DDR5 RDIMM slot on a server or workstation board that supports 2Rx4 registered ECC modules and Samsung DRAM chipsets.
