Server DDR3 kit for registered ECC workloads

This A-Tech kit delivers 128 GB of DDR3 1333 memory in four 32 GB registered ECC modules. It is built for servers and workstations that require quad-rank x4 RDIMMs and will not function in desktop or laptop systems. The modules operate at standard 1.5 V with CL9 latency.

Capacity headroom with 32 GB quad-rank modules

Each 32 GB 4Rx4 module provides high density for multi-socket platforms that support registered DDR3, allowing large virtualisation or database workloads to fit in fewer slots. Systems limited to lower-rank or unbuffered memory cannot use these modules, and total capacity is capped at the platform's registered DIMM limit.

Matched quad-channel kit simplifies deployment

The four modules are factory-matched and tested together, ensuring consistent timing across all channels without manual binning. No additional software or accessories are included; the value is in the verified compatibility and lifetime warranty backing the kit.

Questions about this item

Will these 1333 MHz DDR3 RDIMMs run reliably alongside slower DDR3 modules I already have installed?

The kit runs at 1333 MHz CL9; if mixed with slower DDR3 the system will clock all modules to the lowest speed and loosest timings present.

How can I confirm the 128 GB quad-channel kit is recognised and ECC is active after installation?

Check POST memory count, then verify 128 GB and ECC status in BIOS/UEFI or with dmidecode / lsmem showing registered DDR3 1333 operation.

Does the 240-pin 4Rx4 kit include any cables, brackets or software, or is it only the four 32 GB modules?

Only the four 32 GB DDR3 1333 ECC registered DIMMs are supplied; no cables, brackets or software are included.
