SuperMicro C9Z790-CGW DDR5 kit

This 128GB kit is built for the SuperMicro C9Z790-CGW motherboard. It targets workstation users who need maximum memory capacity on a single consumer-platform board. The four 32GB modules fill every slot to reach the platform limit.

CL46 timing at 5600 MT/s

The modules run at DDR5 5600 with CL46 latency and 1.10V operation. Major OEM Samsung, Micron or Hynix components are used throughout. No heat spreaders are fitted, so airflow in the chassis handles cooling.

128GB across four ranks

Four dual-rank 2Rx8 UDIMMs provide 128GB of non-ECC memory. This density suits large datasets, virtual machines and AI workloads that fit in system RAM. Workloads needing ECC protection or more than four slots cannot use this kit.

Questions about this item

Will the 2Rx8 DDR5 modules need any firmware updates or re-seating after the first year?

No firmware updates or scheduled re-seating are required for the 2Rx8 DDR5 modules once installed correctly.

What limits sustained throughput first — the CL46 latency or the 5600 MT/s bus speed?

The 5600 MT/s bus speed sets the peak bandwidth ceiling; CL46 latency affects access time but does not cap sustained throughput.

How much heat do the four 32 GB sticks produce at 1.1 V running all day in a SuperMicro C9Z790-CGW?

At 1.1 V the modules run cool enough for standard case airflow; no heat spreaders are fitted, so ordinary chassis fans are sufficient.
