192GB DDR5 kit for ASRock Z790 Lightning WiFi

This 192GB kit contains four 48GB DDR5 UDIMM modules rated at 4800 MT/s with CL40 latency. It is built for the ASRock Z790 Lightning WiFi motherboard and targets users who need maximum memory capacity for workstations or heavy multitasking. The modules operate at the standard 1.1V DDR5 voltage and use a 2Rx8 organisation.

Check motherboard slot count and BIOS support

Verify that your ASRock Z790 Lightning WiFi has four DDR5 slots available and that the BIOS recognises 48GB density modules. The kit is non-ECC and unbuffered, so it will not work in platforms that require registered or error-correcting memory. Confirm the board's qualified vendor list includes this part number before ordering.

Standard voltage and no heat spreaders

The modules run at the JEDEC 1.1V nominal voltage, so power draw stays within baseline DDR5 limits. No heat spreaders are fitted, which keeps the profile low but means airflow over the PCB is required for sustained loads. Expect typical DDR5 thermals and silent operation with adequate case ventilation.
