®®
®®
®
98SE/2000/ME/XP without having to go through the sometimes tiresome process of closing files, applications and operating system. This is because the system is capable of storing all programs and data files during the entire operating session into RAM (Random Access Memory) when it powers-off. The operating session will resume exactly where you left off the next time you power-on the system.
Important:
The 5VSB power source of your power supply must support
1A.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to either power-on the system manually, let the system power-on automatically or return to the state where you left off before power failure occurs.

2.2 System Memory
Warning:
Electrostatic discharge (ESD) can damage your system board, processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.
The system board supports DDR SDRAM DIMM. Double Data Rate SDRAM (DDR SDRAM) is a type of SDRAM that doubles the data rate through reading and writing at both the rising and falling edge of each clock. This effectively doubles the speed of operation therefore doubling the speed of data transfer.
The four DDR DIMM sockets on the system board are divided into 2 channels:
Channel 0 - DDR 1 and DDR 2 Channel 1 - DDR 1 and DDR 2

Hardware Installation
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the memory channels.
Virtual Single Channel (VSC)
If both channels are populated with different memor y configurations, the MCH defaults to Virtual Single Channel.
Dual Channel (DC)
Dual channel provides better system performance because it doubles the data transfer rate.
Dynamic Mode Addressing
This mode minimizes the overhead of opening/closing pages in memor y banks allowing for row switching to be done less often.
DIMMs are on the same channel.
DIMMs in a channel can be identical or
completely different.
Not all slots need to be populated.
DIMMs of different memory configura-
tions are on different channels.
Odd number of slots can be popu­lated.
DIMMs of the same memory configu­ration are on different channels.
In single channel, requires even number or rows (side of the DIMM) populated. This mode can be enabled with 1 SS, 2 SS or 2 DS.
In VSC mode, both channels must have identical row structure.

2.3.3 Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heatsink. Without sufficient air circulation across the CPU and heat sink, the CPU will overheat damaging both the CPU and system board.
Note:
Only use Intel® certified fan and heat sink.
An Intel® boxed processor package contains a retention
mechanism, heat sink, fan and installation guide. If the installation procedure in the installation guide differs from the one in this section, please follow the installation guide in the package.
If you are installing a non-boxed processor, the heat sink, fan and retention mechanism assembly may look different from the one shown in this section but the procedure will more or less be the same.

3.1.3.8 System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM addressed at F0000H-FFFFFH are cached, provided that the cache controller is enabled. The larger the range of the Cache RAM, the higher the efficiency of the system.
3.1.3.9 Video BIOS Cacheable
As with caching the system BIOS, enabling the Video BIOS cache will allow access to video BIOS addresssed at C0000H to C7FFFH to be cached, if the cache controller is also enabled. The larger the range of the Cache RAM, the faster the video performance.
3.1.3.10 Memory Hole At 15M-16M
In order to improve system performance, cer tain space in memory can be reserved for ISA cards. This memor y must be mapped into the memor y space below 16MB . When enabled, the CPU assumes the 15­16MB memor y range is allocated to the hidden ISA address range instead of the actual system DRAM. When disabled, the CPU assumes the 15-16MB address range actually contains DRAM memor y. If more than 16MB of system memor y is installed, this field must be disabled to provide contiguous system memor y.
3.1.3.11 AGP Aperture Size (MB)
This field is relevant to the memory-mapped graphics data of the AGP card installed in your system. Leave this in its default setting.
3.1.3.12 Init Display First
