128GB DDR5 kit for Supermicro X13SAE

This 128GB kit contains four 32GB DDR5 UDIMMs rated at 5600 MT/s with CL46 latency and 1.1V operation. The modules are non-ECC, unbuffered, and built with major OEM chips from Samsung, Micron, or Hynix. They are validated specifically for the Supermicro X13SAE motherboard to ensure full capacity recognition and rated speed operation.

Sustained operation at rated specification

The kit runs at its advertised 5600 MT/s, CL46, and 1.1V continuously without requiring voltage increases or timing relaxation. The 2Rx8 organization is the exact rank structure the X13SAE memory controller expects, preventing downclocking or instability during prolonged workloads. Major OEM DRAM and factory testing at these parameters deliver consistent throughput for memory-intensive applications.

DDR5 UDIMM platform limits

DDR5 UDIMM topology on consumer and workstation platforms typically caps at four slots, so this four-module kit fills the board completely. The 288-pin interface and unbuffered signalling are mandatory for the X13SAE; registered or ECC modules will not function. Total capacity cannot exceed the board's maximum supported memory per slot or per channel without a different motherboard.

Questions about this item

How much power does the 128GB DDR5 5600 kit draw at its 1.1V rating?

Each module runs at 1.10V, the standard DDR5 operating voltage, so the four 32GB sticks together draw only the power the memory controller supplies at that level.

What motherboard slot and memory type must I already have for this 288-pin UDIMM kit to work?

The kit needs a desktop board with four 288-pin DDR5 UDIMM slots that support non-ECC unbuffered memory at 5600 MT/s.

Will the 2Rx8 organization of these sticks work with the Supermicro X13SAE memory population rules?

The kit is verified for the X13SAE, matching the board's required rank, voltage and timing so the controller recognises all 128GB at the rated 5600 speed.
