Server ECC RDIMM kit

This NEMIX RAM kit provides 768GB of registered DDR5 memory across six 128GB modules. It is built for enterprise servers that require error-correcting code and registered signal buffering at 5600MHz. The product is not for desktop PCs or workstations that accept only unbuffered UDIMMs.

288-pin DDR5 installation

Each module uses the standard 288-pin DDR5 form factor and operates at 1.1V with a CAS latency of 46. Installation follows normal DIMM seating procedure, but mixing registered and unbuffered modules will prevent boot. Population rules vary by platform, so consult the server manual for approved slot configurations.

Verify registered DDR5 support

Confirm that your motherboard and CPU support registered DDR5 RDIMMs at the PC5-44800 data rate before ordering. Systems limited to unbuffered memory or earlier DDR generations will not accept these modules. Capacity per slot and maximum total memory are platform-specific limits you must check.

Questions about this item

How can I verify the 768GB kit is running at DDR5 5600 with CL46 after installation?

Check the BIOS or UEFI memory information screen; it should show 5600 MT/s, 1.1 V and CAS latency 46 for each of the six 128 GB modules.

What comes in the box and do I need any extra parts to install the six 288-PIN RDIMMs?

The kit includes six 128 GB DDR5 5600 ECC registered DIMMs; no additional components are required if your server has free 288-PIN DDR5 RDIMM slots.

Which capacity version should I choose for a server that supports up to 768 GB of DDR5 5600 registered ECC memory?

This 768 GB (6 × 128 GB) kit matches the maximum supported capacity and provides 2Rx4 organisation for optimal density.
