64GB DDR5 kit for Supermicro workstations

This 64GB kit contains four 16GB DDR5 4800 UDIMM modules built for Supermicro desktop and SuperWorkstation platforms. It targets IT professionals and builders who need validated, non-ECC memory for memory-intensive workloads on supported motherboards such as the MBD-C9Z790-CGW.

Sustained load stability at 1.1V

Modules are stress-tested under load to maintain stability during extended compute sessions. The 1.10V operating voltage and CL40 latency support consistent throughput for rendering, virtualization and data-processing tasks without thermal throttling concerns.

Unbuffered 288-pin layout without spreaders

The 288-pin unbuffered design fits standard DDR5 UDIMM slots and the low-profile modules sit cleanly alongside large CPU coolers. Buyers who require ECC error correction or registered signalling should select a different kit, as this product provides neither.

Questions about this item

Will the 1.10 V DDR5 4800 modules stay cool and quiet during all-day workloads?

Running at the standard 1.10 V DDR5 voltage with no heat spreader, these UDIMMs rely on case airflow; power draw is typical for 4800 MT/s CL40 kits, so noise and heat depend on your chassis cooling.

What motherboard slot and CPU memory controller do I need for this 288-pin UDIMM kit to work?

You need a desktop board with four 288-pin DDR5 UDIMM slots and a CPU that supports DDR5 4800 non-ECC unbuffered memory; the kit is validated for Supermicro C9Z790-CGW workstations.

Can I mix this 1Rx8 CL40 kit with other DDR5 sticks I already own?

Mixing ranks, latencies or voltages can prevent the system from training at 4800 MT/s; for guaranteed stability, populate all four slots with this matched 64 GB kit.
