► Memory Remap Feature
This item is used to enable/disable memory remap feature. Its mainly for if you have a 64bit
OS and 4GB of RAM. Basically it allows you to remap the overlapped PCI memory above the
total physical memory.
► DRAM Frequency
This item is used to adjust the DRAM frequency. Select [Auto] for SPD enable mode. You also
can select a value manually such as [800 MHz].
► Memory Command Rate
This feature allows you to select the delay between the assertion of the Chip Select signal till
the time the memory controller starts sending commands to the memory bank. The lower the
value, the sooner the memory controller can send commands out to the activated memory
bank. Options are Auto, 1T and 2T.
► Memory Timing by SPD
This item is used to enable/disable provision of DRAM timing by SPD device. The Serial
Presence Detect (SPD) device is a small EEPROM chip, mounted on a memory module. It
contains important information about the module's speed, size, addressing mode and various
other parameters, so that the motherboard memory controller (chipset) can better access the
memory device.
► Memory Hole
This item is used to determine whether the 15M-16M address field of memory is reserved for
the ISA expansion card.
► Initial Graphic Adapter
This item is used to choose the initial graphics controller which will be used as the primary
boot device.
► PEG Port
This item is used to enable/disable PCI Express graphics port.
