Compatible Supermicro Server Upgrade

This NEMIX RAM module adds 16GB of DDR4 3200 ECC unbuffered memory to compatible Supermicro systems. It runs at 1.2V with CL22 latency and uses a 2Rx8 organisation on a 288-pin UDIMM. The kit contains a single stick built with major OEM chips from Samsung, Micron or Hynix.

Replaces Slower Non-ECC Modules

The upgrade makes sense when a Supermicro workstation or server needs error-correcting memory at 3200 speed instead of standard unbuffered RAM. It is not for platforms that require registered DIMMs or for builds that cannot use ECC unbuffered UDIMMs at this voltage and rank configuration.

Simple DIMM Installation

The module seats in a standard DDR4 UDIMM slot without extra cables or tools. Common issues arise when mixing ranks or speeds across channels, or when the BIOS is not updated to recognise 2Rx8 density at 3200 MT/s. Always verify the motherboard qualified-vendor list before fitting.

Questions about this item

Does this 288‑pin DDR4 UDIMM fit a standard server DIMM slot?

Yes, the module uses the standard 288‑pin DDR4 UDIMM form factor, so it seats in any compatible server or workstation slot that accepts unbuffered ECC memory.

What is the correct way to seat the module so the ECC function works?

Align the notch with the slot key, press straight down until both side latches click, then verify in BIOS that ECC is enabled and the system reports 16 GB at 3200 MT/s.

Will the Samsung, Micron or Hynix chips on this 2Rx8 module need any firmware updates later?

No firmware updates are required for the DRAM chips; the module runs at 1.2 V with CL22 timings for its service life.
