The explanation for overspecification and overclocking

B-1

The default specification of Intel

845PE chipset is only able to support

FSB 400/533MHz CPU and DDR 266/333 DRAM technology. However, we

have spent engineering efforts to allow the overspecification and overclocking

of 845PE Max under certain conditions. Here is the information which could

help you to achieve overclocking more easily.

Should you decide to overspec the mainboard, the following conditions

shall be satisfied in order to make overspecification possible.

The explanation for overspecification and

overclocking on Intel

845PE chipset

1. Memory Speed/CPU FSB Overclocking Support Matrix

*: CPU FSB 800MHz/DDR400 is not the default specification of this mainboard.

If you decided to use Intel’s FSB 800MHz CPU to overclock on this

mainboard, DDR400 DRAM modules should be used, and have them

populated in the suggested configuration.

Because Intel’s CPU & chipset only support synchronous mode opeartion,

if you decided to use DDR333 DRAM with FSB 800MHz CPU, the BIOS

will automatically adjust the CPU ratio to the FSB frequency comparable to

DDR333 DRAM, which prevents the CPU from running at FSB800MHz

speed.

Overclocking: Overclocking on this mainboard is only available with this

combination. With this combination, the 800MHz FSB CPU

could be used.

Note: If you want to upgrade to 800MHz FSB with a 533MHz CPU, then you

need to manually set the CPU external frequency to 200MHz. However,

make sure the CPU ratio multiplier is unlocked.
