Setup, Compatibility & Care

To ensure a smooth setup, verify that your processor is on the AMD AM4 socket list. When installing your RAM, ensure sticks are seated in the correct slots (usually the second and fourth slots from the CPU) to enable dual-channel memory mode.

Regarding care, avoid applying excessive pressure when installing the M.2 Shield Frozr, as the thermal pads are delicate. Periodically inspect the heatsinks for dust buildup; using compressed air in a well-ventilated area is the safest way to maintain thermal efficiency over time. Always ensure your system is powered down and the PSU is switched off before modifying hardware or clearing the CMOS.
