A-Tech 64GB DDR4 2933 Server Memory

This 64GB DDR4 2933 module is built for servers and workstations that require ECC load-reduced memory. It installs in a standard 288-pin DIMM slot and operates at the standard 1.20V DDR4 voltage. The single-module design suits administrators upgrading or repairing compatible IBM-Lenovo systems.

Load-Reduced ECC 4Rx4 Architecture

The single specification that decides fit is the 4Rx4 load-reduced ECC organisation. This rank and buffering combination reduces electrical load on the memory bus so dense configurations remain stable. Systems that expect registered or unbuffered DIMMs will not accept this module.

Sustained Workload Stability

Continuous testing at CL21 and 2933 MT/s confirms reliable throughput under prolonged multi-threaded loads. The major-brand chipset maintains signal integrity without throttling during extended virtualisation or database tasks. Error-correcting code corrects single-bit faults in real time to preserve data integrity.

Questions about this item

What does the 2933 MT/s speed mean for real-world throughput in my server?

The module runs at DDR4 2933 MT/s, the rate at which the memory controller moves data on each clock edge; actual bandwidth depends on the platform's channel count and configuration.

How does the ECC LRDIMM 4Rx4 organisation affect what the memory controller can address?

Load-reduced DIMMs buffer the command and data buses, letting the controller drive higher capacities per slot; the 4Rx4 layout presents four ranks of x4 chips for dense 64 GB modules.

Will the 288-pin DDR4 DIMM fit my IBM-Lenovo 01AG633 server's memory slots?

The stick uses the standard 288-pin DDR4 DIMM form factor and 1.2 V operation, matching the physical and electrical slot specification for the 01AG633 platform.
