1.6Onboard buttons

Onboard switches allow you to fine-tune performance when working on a bare or open- case system. This is ideal for overclockers and gamers who continually change settings to enhance system performance.

1.MemOK! button

Installing DIMMs that are not compatible with the motherboard may cause system boot failure, and the DRAM_LED near the MemOK! switch lights continuously. Press and hold the MemOK! button until the DRAM_LED starts blinking to begin automatic memory compatibility tuning for successful boot.
