  • 2Rx8 rank layout fits Supermicro X14SAE rules
  • Major OEM chips tested for reliability

Targeted DDR5 upgrade for Supermicro X14SAE

This 48GB DDR5 4800 UDIMM is built as an exact-match upgrade for the Supermicro X14SAE motherboard. It delivers the precise 2Rx8 rank structure, 1.1V operating voltage and CL40 timing the board's memory controller expects. The non-ECC unbuffered design matches the desktop-class DIMM slots on this platform.

Straightforward UDIMM installation

The 288-pin unbuffered module seats in standard desktop DDR5 slots without tools or cables. Problems usually arise when the motherboard manual's approved DIMM population order is ignored or when mixed capacities prevent the system from recognising the full 48GB. Consult the manual for the correct slot sequence before fitting the module.

DDR5 4800 bandwidth ceiling and capacity limit

The PC5-38400 interface caps peak data rate at the rated 4800 MT/s, so throughput cannot exceed this specification. A single 48GB UDIMM fills one slot, and the board's maximum supported memory per channel or per system will determine whether additional modules can be added. Voltage is fixed at 1.1V with no XMP headroom on this unbuffered part.

Questions about this item

How do I confirm the memory is running at 4800MHz CL40 after installing it in my Supermicro X14SAE?

Enter the BIOS or use a system information tool such as CPU-Z to verify the memory frequency reads 4800MHz and the CAS latency shows CL40; the module should be recognised at its full 48GB capacity without manual tuning.

What does the kit contain and do I need any extra parts to install it?

The kit includes one 48GB DDR5 4800MHz 2Rx8 1.1V CL40 288-pin Non-ECC Unbuffered UDIMM; no additional components are required — just an available DIMM slot on the motherboard.

Which capacity should I choose if I want the exact-match upgrade for this board?

This part number MD38400-4828K1 is the 48GB exact-match upgrade specified for the Supermicro X14SAE; select this capacity to match the board's validated memory population rules.
