Server DDR5 4800 ECC RDIMM kit

This 128 GB kit contains four 32 GB DDR5 4800 modules built to PC5-38400 with CL40 timing at 1.10 V. Registered ECC architecture and 2Rx8 organisation match the Supermicro H14DSG-O-CPU motherboard population rules for full-capacity operation.

Builders who need Registered ECC for this board

Buyers needing unbuffered UDIMM or laptop SODIMM form factors cannot use this kit. Systems limited to lower speeds or different voltage requirements should look elsewhere.

DDR5 4800 CL40 1.10 V spec

The DDR5 4800 CL40 1.10 V rating decides whether this kit runs at its rated speed on the H14DSG-O-CPU. Verify the manual for supported population order and maximum capacity per channel before installation.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DSG-O-CPU DIMM slots?

Yes, the 288-pin Registered DDR5 form factor matches the board's RDIMM slots exactly; UDIMM or SODIMM modules would not seat.

What population order should I follow when installing the four 32 GB sticks?

Install modules in the sequence shown in the Supermicro H14DSG-O-CPU manual so the memory controller recognises the full 128 GB at DDR5-4800.

How do I know if a module needs replacement later?

ECC corrects single-bit errors on the fly; persistent corrected-error logs or uncorrectable errors reported by the OS indicate a stick should be swapped.
