128GB DDR5 ECC UDIMM kit

This NEMIX RAM kit provides 128GB of DDR5 memory across four 32GB unbuffered ECC UDIMMs. It operates at 5600MHz with CL46 latency at 1.1V. The modules use a 2Rx8 rank configuration and 288-pin form factor. They are built with major OEM chips from Samsung, Micron, or Hynix and have no heat spreader.

For Supermicro X14SAE workstations

This kit is spec-matched for the Supermicro X14SAE motherboard requiring DDR5 5600 ECC unbuffered UDIMMs. ECC corrects single-bit errors to prevent data corruption and crashes. Builders needing registered RDIMMs, SODIMMs, non-ECC memory, or a different speed grade should look elsewhere. Verify your manual for population rules and maximum supported capacity before buying.

2Rx8 rank and 1.1V voltage

The memory controller on the X14SAE expects a 2Rx8 organization at 1.1V to train at the rated 5600MHz. Using modules with a different rank structure or voltage will prevent the system from recognizing the full 128GB capacity or running at the specified speed. This kit matches those exact electrical and timing parameters.

Questions about this item

What does DDR5-5600 CL46 mean for actual throughput on the Supermicro X14SAE?

The kit runs at 5600 MT/s with CL46 latency, giving the board its rated PC5-44800 bandwidth per module.

Does this kit use the 288-pin DDR5 UDIMM interface the X14SAE requires?

Yes, each module is a 288-pin unbuffered ECC UDIMM, the exact form factor the motherboard's slots accept.

Will the four 32 GB sticks fit the X14SAE's DIMM slots without a heat spreader?

The modules have no heat spreader, so they occupy standard UDIMM height and install directly into the board's four slots.
