睇左770DE+ 既說明書....
Memory Clock
This item can be set by the code using [Auto]. You can set one of the
standard values as listed: [200 MHz (DDR2 400)], [266 MHz (DDR2 533)],
[333 MHz (DDR2 667)] and [400MHz (DDR2 800)]. If you adopt Phenom
CPU, there is one more option: [533MHz (DDR2 1066)]
應該唔止咁少選擇.....
不過 你都可以(266 ~ 300)x 11 (升外頻, 降倍頻)
咁ram 果度可以set 番 266 1:1....
