128GB DDR5 kit for SuperMicro C9Z790-CG

This 128GB kit contains four 32GB DDR5 5600 UDIMM modules tested for the SuperMicro C9Z790-CG motherboard. The non-ECC unbuffered design operates at 1.1V with CL46 timing. It targets workstation and desktop users who need maximum supported capacity on this platform.

Suited for memory-intensive workloads on this

Builders who need ECC error correction, registered modules, lower latency than CL46, or speeds above 5600MT/s should look elsewhere. The kit is not intended for laptops, servers requiring registered DIMMs, or motherboards outside the validated compatibility list.

Four ranks per module deliver 128GB total capacity

Each 2Rx8 module provides two ranks, giving the memory controller ample parallelism for multitasking and large datasets. The CL46 latency and 5600MT/s rate set the performance ceiling; applications needing tighter timings or higher bandwidth will reach the limits of this specification.

Questions about this item

Does the SuperMicro C9Z790-CG motherboard need all four DDR5 slots populated for this 128 GB kit to run?

The kit provides four 32 GB modules, matching the board's four UDIMM slots so you can fill every channel at once.

Can I keep my existing DDR5 4800 modules installed with these CL46 5600 sticks?

Mixing speeds forces all modules to run at the lowest common rate, so the 5600 MT/s modules would drop to 4800 MT/s.

How do I confirm the system is running at DDR5 5600 CL46 after installation?

Check the memory speed and latency in BIOS or a tool like CPU-Z; they should show 5600 MT/s and CL46 timings.
