128 GB DDR5 kit for ASUS Z790

This 128 GB kit contains four 32 GB DDR5 5600 UDIMMs tested for ASUS ROG Strix Z790-A, Z790-E and Z790-F motherboards. It targets builders and IT professionals who need maximum non-ECC capacity on these specific platforms.

No heat spreaders or software included

The modules ship without heat spreaders and rely on the motherboard airflow for cooling. No additional software, drivers or RGB utilities are bundled; the kit is a pure memory upgrade.

Verify four-slot support and DDR5 voltage

Confirm your Z790 board provides four DDR5 slots and can run 1.1 V at 5600 MT/s with 2Rx8 modules. Systems limited to two slots or locked to lower voltages will not accept the full kit.

Questions about this item

Will the four 32 GB modules need any periodic cleaning or component replacement after installation?

No routine maintenance is required; the modules are solid-state with no moving parts and carry a lifetime replacement warranty from the manufacturer.

What is the first timing limit reached when the kit runs continuously at its rated 5600 MT/s speed?

The CAS latency of CL46 is the primary timing constraint that defines sustained operation at the advertised data rate.

How much heat and power does the 128 GB kit produce when all four sticks run all day at 1.1 V?

Operating at 1.10 V without a heat spreader, the unbuffered DDR5 modules generate modest heat and draw low power typical for standard-voltage DDR5 UDIMMs.
