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.

Frågor om den här produkten

Can I add this 64GB 2400 MHz DDR4 LRDIMM alongside existing DDR4 2400 registered DIMMs in the same server?

This module runs at DDR4 2400 (PC4-19200) with CL17 at 1.20V as a 4Rx4 load-reduced DIMM. Mixing LRDIMMs with standard registered DIMMs is not supported by server platforms; all slots must use the same memory type for the system to boot and operate correctly.

How can I verify the module is detected and running at 2400 MHz with ECC active after installation?

Enter the server BIOS or UEFI and check the memory configuration screen; it should show a 64GB DDR4 2400 MHz LRDIMM with ECC enabled. The operating system can also confirm the speed and ECC status using tools such as dmidecode on Linux or the System Information utility on Windows.

What is included in the box and do I need any extra parts to install this 288-pin DDR4 LRDIMM?

The box contains one 64GB A-Tech DDR4 2400 ECC LRDIMM module (288-pin). No additional cables, brackets or cooling parts are required; the module installs directly into an available DDR4 DIMM slot on a compatible server motherboard.
