Exact DDR5 ECC UDIMM for Supermicro X14SAE

This 48GB DDR5 4800MHz module is built as a direct memory upgrade for the Supermicro X14SAE motherboard. The unbuffered ECC UDIMM matches the board's 288-pin slot and memory population rules so the controller recognises the full capacity at rated speed. It targets administrators and workstation builders who need error-correcting memory without registered DIMM complexity.

Unbuffered 2Rx8 layout with major OEM chips

The stick uses Samsung Micron or Hynix components in a 2Rx8 organisation running at 1.1V CL40. No heat spreader is fitted so the low-profile PCB sits cleanly in dense server chassis where airflow is tight. The 288-pin gold edge connector aligns with the X14SAE DDR5 slots and the unbuffered design means no register delay for the memory controller.

Single-module kit simplifies population

The package contains one 48GB UDIMM so you can fill slots in the exact order the manual prescribes without splitting multi-stick kits. ECC circuitry detects and corrects single-bit errors on the fly protecting data integrity during long compute runs. Lifetime replacement coverage and US-based technical support back the module after installation.

Questions about this item

Does the DDR5 4800 PC5-38400 interface limit the module to 4800 MT/s on the Supermicro X14SAE?

Yes, the module is rated at 4800 MT/s and the PC5-38400 designation confirms that peak transfer rate; the board will run it at that speed when populated correctly.

What physical slot and clearance does the 288-pin UDIMM need on the X14SAE?

It requires a standard 288-pin DDR5 UDIMM slot; the module has no heat spreader, so it fits under most CPU coolers, but verify the motherboard manual for DIMM population order.

How is the ECC UDIMM installed and what step is often missed?

Power off, open the retention clips, align the notch with the key, press firmly until both clips click, then confirm in BIOS that the full 48 GB is detected and ECC is enabled.
