SuperMicro C9Z790-CGW compatible kit

This 64 GB kit contains two 32 GB DDR5 5600 CL46 modules built for the SuperMicro C9Z790-CGW motherboard. The unbuffered non-ECC UDIMMs run at 1.1 V and use 2Rx8 organisation. They suit professionals who need reliable capacity for workstation workloads on this specific platform.

Thermals and power at 1.1 V

Operating at 1.10 V keeps power draw low and heat output minimal during typical desktop and workstation tasks. Without a heat spreader the modules rely on case airflow, which is sufficient at the rated voltage and speed. Noise remains unchanged because the kit adds no active cooling.

What the kit includes

The package delivers exactly two 288-pin DDR5 UDIMMs totalling 64 GB with a tested CAS latency of 46. No additional software, cables or accessories are supplied; the modules install directly into the motherboard slots.

Questions about this item

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

Align the notch on each 288-pin module with the slot key, press down firmly until both side clips click shut, then enable XMP or manually set 5600 MT/s and CL46 in the BIOS — the speed step is the one most builders forget.

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

No heat spreader is fitted, so keep the case airflow clean; the modules themselves have no serviceable parts and are covered by a lifetime replacement warranty if a stick ever fails.

What limit appears first under sustained load with these CL46 1.1 V modules?

The CAS latency of 46 cycles at 1.10 V is the primary timing ceiling; thermals are secondary because the sticks run unbuffered and without spreaders.
