Exact-fit DDR5 server kit

This NEMIX RAM kit delivers 128GB across eight 16GB DDR5-4800 RDIMMs tuned to CL40 at 1.1V. Registered ECC construction matches the Supermicro H14DSG-OD memory controller so every slot populates at rated speed without down-clocking. The 1Rx8 organisation and 288-pin form factor follow the board's population rules precisely.

For registered-ECC platforms only

Suits administrators upgrading a Supermicro H14DSG-OD that requires registered DDR5 ECC modules in an eight-DIMM configuration. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or a different capacity per module should look elsewhere. The kit assumes the motherboard manual confirms this exact population order and voltage.

Sustained enterprise stability

Registered buffering offloads the memory controller so all eight modules run fully populated under continuous load while ECC corrects single-bit errors on the fly. Operation stays at the specified 1.1V and CL40 timing without thermal throttling because no heat spreader is fitted. Verify the system manual for approved population sequences before deployment.

Questions about this item

Do I need a Supermicro H14DSG-OD motherboard with DDR5 RDIMM slots to install this 288-pin kit?

Yes. This kit is built for the Supermicro H14DSG-OD and requires a board that accepts 288-pin DDR5 Registered ECC RDIMMs running at 1.1 V.

Can I keep existing DDR5 RDIMMs in the other channels while adding these eight 16 GB 1Rx8 modules?

The board must be populated following its validated sequence; mixing ranks or speeds can force all channels down to the slowest common timing.

How do I confirm the full 128 GB is recognised at DDR5-4800 CL40 after installation?

Check the BIOS memory information screen — it should show 128 GB total, 4800 MT/s data rate and CAS latency 40 with ECC active.
