HT_Width

This item shows Hyper Transport TM ‘s bus size of

8 bits

 

 

 

Local Descriptor Table (LDT). The bus size is

16 bits

 

 

 

automatically calculated by the CPU. Therefore, we

Auto

 

 

 

strongly recommend that you do not change this

 

 

 

 

setting.

 

 

 

 

 

 

 

 

HT_Speed

This item shows the bus frequency of Local

200 MHz

 

 

 

Descriptor Table(LDT). Its default is setting as

400 MHz

 

 

 

800MHz.

600 MHz

 

 

 

 

800 MHz

 

 

 

 

 

 

 

DDR Timing

Set this to the default value to enable the system to

Manual

 

 

Setting by

automatically set the DDR timing by SPD(Serial

Auto

 

 

 

Presence Detect). SPD is an EEPROM chip on the

 

 

 

 

DIMM module that stores information about the

 

 

 

 

memory chips it contains, including size, speed,

 

 

 

 

voltage, row and column addresses, and

 

 

 

 

manufacture. If you disable this item, you can use

 

 

 

 

the following three items to manually set the timing

 

 

 

 

parameters for the system memory.

 

 

 

 

 

 

 

 

Max Memclock

When DDR Timing Setting by is set to Manual, use

200

 

 

(Mhz)

this item to set the DRAM frequency.
