A-Tech 64GB DDR4 2400 ECC LRDIMM 4Rx4 Server Memory

64GB DDR4 2400 ECC LRDIMM for Cisco Servers

This 64GB DDR4 2400 module is a load-reduced DIMM built for Cisco UCS-ML-1X644RV-A and 15-104063-01 systems. It targets administrators who need registered ECC memory with a 4Rx4 organisation to expand compatible server platforms. The single 288-pin stick operates at 1.20V with a CAS latency of 17.

Capacity and headroom: 64GB per module

A single 64GB stick provides substantial capacity for virtualisation hosts, in-memory databases or dense VDI deployments. The 4Rx4 layout maximises density per slot, though the quad-rank electrical load limits how many modules the memory controller can drive at the rated 2400 MT/s. Workloads that exceed this capacity must add modules within the platform’s rank and channel limits.

DDR4 2400 interface constraints

The PC4-19200 interface caps peak bandwidth at the DDR4 2400 data rate, so throughput scales with populated channels rather than per-module speed. Mixing ranks or exceeding the controller’s maximum supported ranks per channel will force a downshift below 2400 MT/s. The 262-pin form factor noted in supplier data is a labeling inconsistency; this module uses the standard DDR4 288-pin DIMM connector.
