High-density DDR4 ECC kit

This NEMIX RAM kit delivers 1.5TB of registered DDR4 memory across twelve 128GB modules. It runs at 3200 MT/s with CL22 latency at 1.2V. ECC and 4Rx4 organisation protect data integrity in multi-socket servers and workstations.

Suited for memory-bound server workloads

Virtualisation hosts, in-memory databases and large-scale compute nodes benefit from the high capacity and registered design. Systems limited to fewer than twelve DIMM slots, consumer motherboards without ECC support or platforms capped below 3200 MT/s cannot use this kit fully.

Twelve matched modules simplify deployment

The pre-validated 12x128GB configuration removes the need to source and qualify individual sticks. Major OEM DRAM from Samsung, Micron or Hynix ensures consistent quality across the kit. No heat spreaders are included, so airflow planning remains the integrator's responsibility.

Questions about this item

Does this 12 x 128 GB DDR4 RDIMM kit require a motherboard with 12 DIMM slots?

Yes, the kit contains 12 registered DIMMs, so the host board must provide 12 DDR4 RDIMM slots and support 1.5 TB total capacity.

Can I mix these 4Rx4 modules with older 2Rx4 DDR4 RDIMMs?

Mixing different rank configurations is not recommended; the memory controller will typically clock all channels to the slowest common settings and may limit total capacity.

How can I verify the kit runs at DDR4 3200 CL22 after installation?

Check the BIOS memory information or use a tool such as CPU-Z to confirm each module reports 3200 MT/s, CL22 timing and 1.20 V operation.
