Capacity and fit

This 64 GB kit contains two 32 GB DDR5 UDIMMs built for the SuperMicro MBD-C9Z790-CGW motherboard. It targets system builders and IT professionals who need validated, non-ECC memory for workstation or gaming workloads on that platform.

Thermals and power

Modules run at 1.1 V with a CL46 latency and no heat spreader, relying on case airflow for cooling. The low voltage keeps power draw modest during typical desktop and workstation tasks.

Sustained load behaviour

Each module uses a 2Rx8 organisation with major OEM Samsung, Micron or Hynix chips. Rigorous stress testing under load is performed to confirm stability during extended compute sessions.

Questions about this item

How do I install the 288-pin DDR5 UDIMM modules on the SuperMicro MBD-C9Z790-CGW, and what step is often missed?

Align the notch on each 288-pin module with the slot key, press firmly until both retention clips click, then enable XMP or EXPO in BIOS to run at 5600 MT/s instead of the default JEDEC speed.

What maintenance or replacement will the 64GB kit need later?

No periodic maintenance is required; the modules have no heat spreader and run at 1.1 V, so only replace them if a module fails or capacity needs exceed 64 GB.

What limit appears first under sustained load with these CL46 2Rx8 modules?

The primary limit is CAS latency 46 at 5600 MT/s; bandwidth and voltage remain stable, so latency-sensitive workloads hit the timing ceiling before thermal or power limits.
