select the best option in the “ CAS Latency Time “
To “System Memory Frequency “fields.
z
CAS Latency Time
This refers to the Column Address Strobe delay time. Lower is
better! However, in a P4 system, lowering this setting only
improves performance minimally, so it might be better to
increase this setting to gain stability or a higher over clock.
z Active Precharge Delay
This refers to the Active to Precharge delay time. Lower is
better! However, same as above, lowering this setting only
improves performance minimally, so it might be better to
increase this setting to gain stability or a higher over clock.
z DRAM RAS# to CAS# Delay
This refers to the Row Address Strobe to Column Address
Strobe delay time. Lower is better! This is the most crucial
setting in a P4 system! Lowering this setting improves
performance quite noticeably, so you might want to sacrifice
some clock speed to lower this timing.
z DRAM RAS# Precharge
This refers to the Row Address Strobe to Column Address
Strobe delay time. Lower is better! This is the 2nd most
crucial setting in a P4 system! Lowering this setting
improves performance quite noticeably, so you might want to
sacrifice some clock speed to lower this timing
z System Memory Frequency
The Intel 865G Support Intel DDR 266/333/400.This setting
could help you and setup the DRAM clock for DDR memory
module. The default setting was Auto
