Setup Tips
Update the BIOS First
If using a 13th or 14th Gen Intel processor, use the BIOS FlashBack button to update the firmware to the latest version before installing other components.
Proper DDR5 Installation
Insert DDR5 memory modules firmly into slots DIMM_A2 and DIMM_B2 first (the second and fourth slots away from the CPU socket) for optimal dual-channel stability.
Utilize M.2 Q-Latches
Take advantage of the tool-free M.2 Q-Latch plastic rotating clips on the storage slots to secure your NVMe SSDs without fussing with tiny screws.
Connect ProCool Power Cables
Ensure both the 8-pin and 4-pin ATX 12V power connectors from your power supply are securely plugged into the motherboard to supply clean current for CPU overclocking.
