IMB200 LGA775 ATX MB User Manual

Manual If you want better performance for your system other than the one by SPD select Manual then select the best option in the CAS Latency Time To System Memory Frequency fields.

zCAS 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.

zActive 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.

zDRAM 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.

zDRAM 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

zSystem 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

zSystem BIOS Cacheable

When this field is enabled, accesses to the system BIOS ROM

Address at F0000H-FFFFFH are cached, provide that the cache controller is enabled.

zVideo BIOS Cacheable

As with caching the system BIOS, enabling the Video BIOS
