bled, then FSB is set to 1600MHz and you can not overclock further. If it is disabled, then you
can use other items in this menu to configure your system.
► CPU Clock
This option is used to set the CPU clock.
► PCI Express Clock
This option is used to set the speed of PCI Express slot. It may enhance the graphics card
speed.

► DRAM Timing Selectable
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 DDR2 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. Select [Manual], then you can configure DRAM timing by
yourselves.
