Server Memory Upgrade

A-Tech 32GB DDR3L 1600 ECC LRDIMM is a load-reduced server memory module built for Supermicro platforms. It uses Samsung chips in a 240-pin form factor to expand system capacity for virtualisation and database workloads.

Quad-Rank 4Rx4 Configuration

This module presents a 4Rx4 organisation that the memory controller must support. Verify your motherboard qualification list for 32GB quad-rank LRDIMM compatibility before ordering.

Low-Voltage Operation

Rated at 1.35V DDR3L, the module draws less power than standard 1.5V DDR3 at the same 1600MHz speed. Lower voltage reduces thermal load in dense multi-DIMM configurations.

Questions about this item

How does the 32 GB quad-rank module behave once it is installed in a live server?

The 4Rx4 organisation spreads the 32 GB across four logical ranks, letting the memory controller interleave requests and keep bandwidth high even under heavy multi-threaded loads.

What does the DDR3L 1600 (PC3L 12800) rating limit in practice?

The DDR3L 1600 interface sets the maximum data rate at 1600 MT/s, so the module cannot exceed that transfer speed regardless of the platform it is paired with.

What physical slot and clearance does this 240-pin LRDIMM need?

It requires a standard 240-pin DDR3 DIMM socket and enough vertical clearance for the low-profile load-reduced module height.
