SuperMicro ECC UDIMM Kit

This 128GB kit contains four 32GB DDR4 3200 modules built for SuperMicro motherboards. It targets administrators who need error-correcting memory in unbuffered form for workstation or entry-level server boards. The 2Rx8 organisation and CL22 timing suit platforms that require ECC without registered buffering. Buyers needing registered DIMMs or higher frequencies must look elsewhere.

288-pin unbuffered design

Each module operates at 1.2V and fits standard DDR4 UDIMM slots on compatible SuperMicro systems. The lack of heat spreaders keeps the profile low for dense chassis layouts. Unbuffered ECC means the memory controller talks directly to the DRAM, so the board must support that topology. Systems requiring registered or load-reduced modules cannot use this kit.

Major OEM chip selection

Samsung, Micron or Hynix ICs are used depending on supply, all stress-tested under load before shipping. The package includes only the four UDIMMs; no software, cables or additional hardware are bundled. Installers should consult the motherboard manual for population rules and BIOS settings. Those wanting pre-applied thermal pads or RGB lighting will not find them here.

Questions about this item

What does the PC4-25600 rating mean for real-world DDR4-3200 speed?

PC4-25600 is the peak transfer rate label for DDR4-3200; the modules run at 3200 MT/s with a CAS latency of 22 cycles at 1.20 V.

Will these 288-pin UDIMMs physically fit a standard desktop DIMM slot?

Yes, they are 288-pin DDR4 ECC UDIMMs, the same keying used in consumer desktop slots, but the motherboard must support unbuffered ECC.

Do I need to enable anything in BIOS after installing the 4×32 GB kit?

Enter BIOS and verify the memory is recognised at 3200 MT/s; if it defaults to a lower speed, select the XMP or DOCP profile to reach the rated frequency.
