Memory Frequency For
for FSB(Front Side Bus) frequency =400MHz,
2.66 Memory Frequency = Host clock X 2.66.
Auto Set M emory frequency by DRAM SPD data. (Default v alue)
for FSB(Front Side Bus) frequency =533MHz,
2.0 Memory Frequency = Hos t clock X 2.0.
2.5 Memory Frequency = Hos t clock X 2.5.
Auto Set M emory frequency by DRAM SPD data. (Default v alue)
for FSB(Front Side Bus) frequency =800MHz,
2.0 Memory Frequency = Hos t clock X 2.0.
1.6 Memory Frequency = Hos t clock X 1.6.
1.33 Memory Frequency = Host clock X 1.33.
Auto Set M emory frequency by DRAM SPD data. (Default v alue)
