4.2.3.4DRAM RAS# Precharge

If an insufficient number of cycles are allowed for the RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system.

4.2.3.5Precharge Delay (tRAS)

Select the operating system that is active to precharge delay.

4.2.3.6System Memory Frequency

You can use this item to select operating frequency for the main system memory.

4.2.3.7SLP_S4# Assertion Width

The item allows you to select the assertion width of SLP_S4#

The choice: 4 to 5 Sec, 3 to 4 Sec, 2 to 3 Sec, 1 to 2 Sec.

4.2.3.8System BIOS Cacheable

Selecting “Enabled” allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

The choice: Enabled, Disabled.

4.2.3.9Video BIOS Cacheable

Select “Enabled” allows caching of the video BIOS, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

The choice: Enabled, Disabled.
