64 GB DDR5 kit for Supermicro C9Z790-CGW

This 64 GB kit contains four 16 GB DDR5 5600 UDIMMs built for the Supermicro C9Z790-CGW motherboard. It targets system builders and IT professionals who need a matched set of non-ECC unbuffered modules for that specific platform.

DDR5 5600 CL46 at 1.10 V

The decisive specification is the DDR5 5600 speed grade with CL46 latency running at 1.10 V. Only boards that accept PC5-44800 1Rx8 288-pin unbuffered UDIMMs can use this kit, so verify the motherboard qualification list before ordering.

Standard voltage and no heat spreader

Operating at the standard 1.10 V DDR5 voltage, the modules draw nominal power without a heat spreader. In typical desktop workloads they run at stock JEDEC settings, producing modest heat and no additional fan noise beyond the system's existing airflow.

Questions about this item

How does the DDR5 5600 speed translate to bandwidth once installed in the SuperMicro C9Z790-CGW?

The kit runs at 5600 MT/s, delivering up to 44800 MB/s of peak bandwidth per module when the motherboard trains the memory at its rated DDR5 5600 setting.

What does the PC5-44800 designation cap in practice?

PC5-44800 confirms the modules are validated for 5600 MT/s operation at 1.10 V with CL46 latency on the C9Z790-CGW platform.

Will the 288-pin UDIMM modules fit the C9Z790-CGW slots without a heat spreader?

Yes, the 288-pin DDR5 UDIMM form factor matches the board's DIMM slots, and the low-profile design without a heat spreader clears standard CPU coolers.
