SuperMicro Compatible DDR5 Kit

This 64GB kit contains four 16GB DDR5 5200 UDIMM modules built for SuperMicro desktop workstations such as the SYS-531AD-I and C9Z790-CG boards. It targets IT professionals and enthusiast builders who need validated, non-ECC unbuffered memory for mission-critical workloads.

Upgrade from slower DDR5 or smaller capacity

The jump is worth it when your current modules run below 5200 MT/s or when the system has fewer than four populated slots, because the 1Rx8 organisation and 1.10V operation keep the memory controller stable at the rated PC5-41600 data rate. Buyers who need ECC protection or registered DIMMs should look elsewhere.

Sustained load behaviour

All modules are rigorously stress tested under load to ensure reliability during extended compute sessions. The absence of a heat spreader means airflow across the PCB manages thermals, so case ventilation must be adequate for continuous operation at CL38 latency.

Questions about this item

Does this 288-pin DDR5 UDIMM kit fit the Supermicro SYS-531AD-I or C9Z790-CG workstation motherboard?

The kit is built for Supermicro desktop and SuperWorkstation systems including the SYS-531AD-I and C9Z790-CG, using the standard 288-pin DDR5 UDIMM form factor.

What is the correct slot population order for the four 16 GB modules on a four-slot board?

Install one module per channel following the motherboard manual — typically slots A2 and B2 first, then A1 and B1 — so the memory controller trains all four 1Rx8 ranks at DDR5 5200.

Will the modules need active cooling or thermal-pad replacement over time?

The sticks ship without a heat spreader and run at 1.10 V; standard chassis airflow is sufficient and no thermal-pad maintenance is required.
