Server Memory Kit

This NEMIX RAM kit delivers 192GB of DDR5 server memory across twelve 16GB registered DIMMs. Each module operates at 6400MHz with a CAS latency of 52 and runs at 1.1V. The 288-pin ECC RDIMM design targets enterprise platforms that require registered, error-correcting memory.

Suited For And Not

The kit suits administrators upgrading or populating servers that accept DDR5 6400 registered ECC modules in a 1Rx8 configuration. It is not for desktop PCs or workstations that use unbuffered consumer memory, nor for systems limited to lower DDR5 speeds or different pin counts.

Deciding Specification

The registered ECC RDIMM form factor is the single specification that decides compatibility. Only motherboards and platforms designed for 288-pin DDR5 registered memory with on-die ECC can use these modules.

Questions about this item

Should I choose the 12-module kit or buy single 16GB sticks instead?

The kit contains twelve matched 16GB modules tested together, so they share identical timings and SPD data; mixing loose sticks can introduce timing mismatches that prevent the full 6400 MT/s speed from being stable.

What does the 6400MHz rating mean once the memory is installed in a server?

The modules are rated to run at 6400 MT/s with a CAS latency of 52 at 1.1 V, provided the server motherboard and CPU memory controller support that data rate and the BIOS is configured for it.

How does the 288-pin DDR5 RDIMM interface limit real-world bandwidth?

Each 288-pin registered DIMM delivers a 64-bit data path at up to 6400 MT/s, so the practical peak bandwidth per module is capped by that bus width and the memory controller's ability to sustain the rated transfer rate.
