NEMIX RAM DDR4 ECC RDIMM 256GB Kit

This NEMIX RAM kit provides 256GB of DDR4 server memory across two 128GB registered DIMMs. It is built for IT professionals managing mission-critical workloads in enterprise servers, workstations and NAS devices. ECC and registered buffering protect data integrity under sustained heavy loads.

Installation Notes for 4Rx4 Registered Modules

Installation is a straightforward DIMM swap that typically takes minutes, but the 4Rx4 organisation demands a motherboard qualified for quad-rank registered memory. The most common issue is a POST failure or reduced speed when the platform firmware does not support this rank configuration. Always consult the system manual for approved population rules before fitting the modules.

Compatibility Checks Before Ordering

Verify that your server or workstation accepts DDR4 3200MHz PC4-25600 registered ECC RDIMMs at 1.2V. Confirm the board supports 128GB per slot and 4Rx4 modules in your planned slot layout. Ensure the BIOS is updated to a version that recognises high-capacity registered DIMMs.

Questions about this item

How do I verify the kit is running at 3200 MHz CL22 1.20V after installation?

Enter the server BIOS or use a tool such as CPU-Z and confirm the memory frequency reads 3200 MT/s, the CAS latency shows 22 and the voltage is set to 1.20V.

What comes in the box and do I need anything else to install the 2 x 128 GB modules?

The kit contains two 128 GB DDR4 ECC RDIMM modules; no extra parts are required if your motherboard has free 288-pin RDIMM slots.

Should I choose this 256 GB 4Rx4 kit or a lower-capacity alternative for my server?

Select this 256 GB kit when the workload demands maximum registered ECC capacity and the board supports 4Rx4 modules; otherwise a smaller kit may suffice.
