Server Memory Upgrade

This A-Tech module is a 4 GB DDR3L ECC registered DIMM built for server and workstation systems that require error-correcting memory. It operates at 1.35 V low voltage and fits standard 240-pin DDR3 slots.

Registered ECC Compatibility

The single specification that decides fit is the registered ECC RDIMM design with a 1Rx4 organisation; only motherboards that explicitly support registered ECC DDR3L at 1333 MHz can use this module.

Capacity And Headroom

The 4 GB capacity suits light virtualization, file serving or legacy application workloads where registered ECC stability is mandatory. It runs out when larger datasets or multiple virtual machines demand more than a single 4 GB rank can provide.

Questions about this item

How does the 1333 MHz speed translate once the module is installed in a server?

The module runs at DDR3L 1333 (PC3L-10600) with CL9 latency, delivering the rated throughput when the platform’s memory controller is set to that frequency.

What does the DDR3L 1.35 V interface limit in practice?

The DDR3L 1.35 V registered DIMM interface caps the operating voltage at 1.35 V, so the module will only work in slots that support DDR3L low-voltage signalling.

Will the 240-pin registered DIMM fit my server’s memory slots?

It uses the standard 240-pin DDR3 DIMM form factor with registered (RDIMM) signalling; verify your system requires registered ECC modules before installing.
