Configure SDRAM Timing by SPD:

SPD is the abbreviation Serial Presence Detect. SPD takes accord the chip types, capacity, timing, voltage data. The system can auto adjust memory according to the data to reach the best situation.

SDRAM RAS# to CAS# delay:

When CPU save data from memory, it has to deliver RAS single first, and then CAS single. The item is to set up the interval between two singles.

RAS# Precharge:

This item is the time when RAS has to re-located.

CAS# Latency:

This item is to set up the time when memory receives one CAS single, after how much clock, the memory starts to write and read data.

Loadoff Cmd Timing:

It is the first read-write action under burst pattern

Memory Hole:

This reserves the 15MB to 16MB memory address space for use of ISA expansion cards.

Graphics Aperture Size:

The item is to set up AGP display to use how much memory to save Texture Data.

8 bit I/O Recovery Time:

The item is to set up CPU to demand ISA Bus 8 bit how much it takes to recovery.

16 bit I/O Recovery Time:

The item is to set up CPU to demand ISA Bus 16 bit how much it takes to recovery.
