DRAM RAS# to CAS# Delay

This item allows you to select a delay time between the CAS and RAS strobe signals. It only applies when DRAM is written to, read from, or refreshed. This field is adjustable only when “DRAM Timing Selectable” is set to “manual”. This field is locked when “DRAM Timing Selectable” is set to “By SPD” and is automatically determined by the system. Options: 4、3、2

DRAM RAS# Precharge

This item allows you to select the DRAM RAS# precharge time. The ROW address strobe must precharge again before DRAM is refreshed. An inadequate configuration may result in incomplete data. This field is adjustable only when “DRAM Timing Selectable” is set to “manual”. This field is locked when “DRAM Timing Selectable” is set to “By SPD” and is automatically determined by the system. Options: 4、3、2

System BIOS Cacheable

When enabled, accesses to system BIOS ROM addressed at F0000H-FFFFFH are cached, provided that the cache controller is enabled. Options: Enabled (default), Disabled

Video BIOS Cacheable

Select “Enabled” to allow caching of the video BIOS which may improve performance. If any other program writes to this memory area, a system error may result. Options: Enabled, Disabled (default)

Memory Hole at 15M-16M

When enabled, you can reserve an area of system memory for ISA adapter ROM. When this area is reserved, it cannot be cached. Refer to the user documentation of the peripheral you are installing for more information. Options: Disabled (default)、Enabled

AGP Aperture Size (MB)

Select the size of the AGP (Accelerated Graphic Port) aperture. The aperture is a portion of the PCI memory address range dedicated for graphic memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation.

Options: 4、8、16、32、64、128 (default)、256

DRAM Data Integrity Mode

If you install the unbuffered/ non-ECC memory DIMMs, this item will auto detect the Non-ECC DRAM mode. If you install the unbufferec/ with-ECC memory DIMMs, this item allows you to select the DRAM mode.

Options: Non-ECC (default)、With-ECC
