sociate addresses with those storage cells.
Of course, that only works if you're using a 64-bit (or 32bit physical address extension (PAE)
enabled) OS that can deal with physical addresses larger than 32 bits.
Once this option is enabled, the BIOS can see 8192 MB of memory.
► Memory Speed Adjust
This item is used to adjust the memory speed. Select [Auto] for SPD enable mode.You also
can select a value manually such as[667 MHz] or [800 MHz].
► 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.
► PEG Port
This item is used to enable/disable PCI Express graphics port.

► SMBUS Controller
The System Management Bus is a specic implementation of an I
2
C bus. The SMBus speci-
cation describes the data protocols, device addresses, and electrical requirements that are
superimposed on the I
2
C bus specication. The SMBus is used to physically transport com-
mands and information between the Smart Battery, SMBus Host, Smart Battery Charger, and
other SMBus Devices.This item is used to enable/disable System Mangement Bus controller.
► SLP_S4# Min. Assertion Width
SLP_S4# is a signal for power plane control. This signal shuts off power to all non-critical
systems when in the S4 (Suspend to Disk) or S5 (Soft Off) state.
This setting indicates the minimum assertion width of the SLP_S4# signal to ensure that the
DRAMs have been safely power-cycled. Setting values are: [4 to 5 seconds], [3 to 4 seconds],
[2 to 3 seconds], [1 to 2 seconds].
