Server ECC LRDIMM kit for enterprise workloads

This 128GB kit contains eight 16GB DDR4 2133 modules built as load-reduced DIMMs with ECC. The 2Rx4 dual-rank x4 organisation and CL15 latency suit multi-socket servers and workstations that need maximum registered capacity. Modules run at the standard 1.2V DDR4 voltage. The product is new and intended for professional environments.

Verify DDR4 LRDIMM support and slot count

Confirm that your platform accepts DDR4 ECC load-reduced DIMMs and provides at least eight 288-pin slots. Desktop and laptop boards cannot use these modules. Check the system manual for approved memory configurations, rank limits per channel and any required population order before ordering.

Standard voltage keeps thermals moderate

Operating at 1.2V DDR4 standard voltage, the modules draw typical power for registered server memory. No heat spreaders are fitted, so airflow across the DIMM rows handles cooling. Acoustic output depends on chassis fan curves rather than the memory itself. Power draw scales with the number of populated channels.

Questions about this item

Does the kit include eight 16 GB modules or do I need to buy them separately?

The kit contains eight 16 GB LRDIMM modules for a total of 128 GB, so nothing else is required.

Should I choose the 2Rx4 dual-rank version or a single-rank alternative for my server?

These modules are 2Rx4 dual-rank x4; select them only if your server's memory configurator lists 2Rx4 LRDIMMs as supported.

What does the 2133 MHz PC4-17000 rating mean once the RAM is installed?

The memory will run at 2133 MT/s with CL15 latency at the standard 1.2 V DDR4 voltage, delivering the rated bandwidth in compatible servers.
