• The default memory operation frequency is dependent on its Serial Presence Detect

(SPD), which is the standard way of accessing information from a memory module.

Under the default state, some memory modules for overclocking may operate at a

lower frequency than the vendor-marked value. To operate at the vendor-marked

or at a higher frequency, refer to section 2.5 Ai Tweaker menu for manual memory

frequency adjustment.

• For system stability, use a more efcient memory cooling system to support a full

memory load (4 DIMMs) or overclocking condition.

• Visit the ASUS website at:
