NEMIX RAM
A 32 GB dual-channel kit of DDR5 5600 UDIMM memory validated for the ASRock Z790 Riptide WiFi motherboard
This NEMIX RAM kit provides 32GB of DDR5 memory in a matched pair of 16GB modules built for the ASRock Z790 Riptide WiFi motherboard. It uses standard 288-pin UDIMM form factor and operates at 1.1V without ECC or buffering. The kit targets builders upgrading that specific board with validated compatibility.
Two 1Rx8 modules deliver 32GB total capacity at DDR5 5600 (PC5-44800) with CL46 latency. The density suits mainstream gaming, content creation and multitasking workloads on the Z790 platform. Heavy virtualisation, large dataset processing or memory-intensive rendering may exceed the available headroom.
Modules run at the standard DDR5 voltage of 1.1V and have no integrated heat spreader. Power draw stays within baseline JEDEC limits for unbuffered UDIMMs. Without a spreader, airflow from the CPU cooler or case fans becomes the primary cooling path; sustained heavy loads may raise module temperatures above spreader-equipped alternatives.
