512 GB DDR5 5600 ECC RDIMM kit

This NEMIX RAM kit provides 512 GB of DDR5 memory across four 128 GB registered DIMMs running at 5600 MT/s with ECC. It is built for servers and workstations that require registered, error-correcting modules rather than standard desktop memory.

4 x 128 GB 2Rx4 modules at 1.1 V

The four 2Rx4 modules deliver high capacity per slot, letting compatible platforms reach 512 GB in just four DIMM sockets. Headroom ends when the platform's memory controller or qualified-vendor list limits speed, rank population or total capacity below these specifications.

Replaces smaller DDR5 RDIMM kits

The kit upgrades systems currently running lower-capacity DDR5 registered ECC modules or incomplete populations. The jump is worthwhile when the workload needs the full 512 GB and the platform supports 128 GB 2Rx4 registered DIMMs at 5600 MT/s.

Questions about this item

Will these 288-pin DDR5 5600 RDIMMs work in the same server as my existing DDR5 4800 modules?

The kit runs at DDR5 5600 PC5-44800; if the server mixes speeds, all channels typically drop to the slowest installed module.

How can I confirm the 2Rx4 ECC registered DIMMs are operating correctly after installation?

Check the BIOS memory info for 512GB total, DDR5 5600 speed, ECC enabled, and registered mode showing 2Rx4 organisation.

Does the 4 x 128GB kit include any extra parts or do I need to buy heatsinks separately?

The box contains only the four 288-pin RDIMMs; no heatsinks, cables or brackets are included.
