128GB DDR3L ECC RDIMM kit

This kit delivers 128GB of DDR3L 1600 memory across eight 16GB registered DIMMs. Each module runs at 1.35V with CL11 latency and 2Rx4 organisation. The 240-pin form factor and ECC registration target workstation and server platforms that require registered memory.

Suited for registered DDR3L systems.

These modules are built for workstations, servers, NAS units and routers that accept DDR3L ECC registered DIMMs. They will not work in standard desktop computers that require unbuffered memory, and they cannot be mixed with unbuffered modules in the same system.

Eight-module capacity for high-density configs

The 128GB total provides ample headroom for virtualisation, large datasets and multi-user workloads on compatible platforms. Capacity limits are reached when the host's memory slots or chipset maximum are filled, so expansion beyond this kit depends on the specific system's supported DIMM count and maximum addressable memory.

Questions about this item

Does my server need 240-pin DDR3L ECC RDIMM slots to use this 128GB kit?

Yes, this kit requires eight 240-pin DDR3L ECC registered DIMM slots running at 1.35V.

Can I mix these 2Rx4 registered modules with any unbuffered DDR3L sticks I already have?

No, registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered modules.

How can I verify the kit is running at DDR3L 1600 CL11 after installation?

Check the BIOS or OS memory report for 1600 MT/s speed, CL11 latency, 1.35V voltage and ECC registered status across all 128GB.
