Server ECC LRDIMM 64GB

This A-Tech module is a 64GB DDR4 2933MHz PC4-23400 ECC Load Reduced DIMM built with Micron chipset. It operates at 1.20V with CL21 latency and a 4Rx4 rank configuration on a 288-pin form factor. Designed as a compatible replacement for specific Micron part numbers, it targets server and workstation environments that require registered ECC memory with load-reduced buffering.

Suited for capacity-bound servers

This module fits administrators upgrading compatible Micron-based platforms that support DDR4 LRDIMM 4Rx4 topology at 2933MHz. It is not suitable for consumer desktops, laptops, or workstations that require unbuffered UDIMM or standard RDIMM modules. Systems limited to lower ranks, non-ECC memory, or different voltage requirements should look elsewhere. Builders needing multiple matched modules must verify platform population rules independently.

Handles large memory footprints

The 64GB density provides substantial headroom for virtualisation hosts, in-memory databases, and compute clusters running memory-intensive workloads. Each module delivers 2933MT/s throughput at standard DDR4 voltage. Capacity scales with available DIMM slots and controller support for 4Rx4 LRDIMM organisation. Workloads exceeding per-slot limits or requiring faster speeds will need alternative configurations.

Questions about this item

What motherboard slot is required for the 288-pin DDR4 DIMM?

The module uses a standard 288-pin DDR4 DIMM slot that supports load-reduced ECC memory at 1.20V.

Can this 4Rx4 LRDIMM be mixed with 2Rx4 registered DIMMs in the same server?

Mixing 4Rx4 load-reduced modules with 2Rx4 registered DIMMs is not supported; all slots must use identical LRDIMM ranks.

How do I confirm the 2933MHz speed and ECC function are active after installation?

Check the BIOS memory information screen for DDR4-2933 MT/s, CL21 timing, and ECC enabled status.
