DRAM Timing Configuration

► Memory Speed Mode

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 [Auto] for SPD enable mode.
Select [Limit], the DRAM speed will not exceed the specified value listed in the "Memory
Speed Adjust" item. If SPD value is faster than "Memory Speed Adjust" value, it will run at the
specified "Memory Speed Adjust" speed. Otherwise, SPD value is selected.

Select [Manual], then DRAM speed is manually selected according to the set value of
"Memory Speed Adjust".

► DRAM Timing Mode

When both DCTs (DRAM controller) are enabled in unganged mode, BIOS must initialize
the frequency of each DCT in order, you also can configure the timings manually.
Settings are : [Auto], [DCT 0], [DCT 1], [Both].
[DCT 1] and [Both] will appear only in AM2+ or AM3 CPU.
