This is one of the few boards that got official overclocking
support after the board was in production for a while.
Ignore the section that talks about changing the multiplier,
as Intel P4 retail processors are locked.
The kicker is, in this configuration, the memory bus only
supports one double sided DDR400 stick of RAM. This is due to
electrical limitations of the chipset and bus. For most
ordinary budgets, that gives you a 512MB double sided DIMM,
as your system memory.
The datasheet for the 845PE states it supports 512mbit chip
technology, with chips either x8 or x16 wide. So, a 1GB
double sided module made from (16) 64Mx8 chips will work, but
the cheaper "stacked" modules made from 128Mx4 won't work.
If you go shopping for a single 1GB PC3200 module, to run
with your FSB800 processor, either buy it from a reputable
manufacturer, like Crucial, Kingston, or even Corsairmicro
has some now, or if you go for a generic from Pricewatch,
get a money back guarantee that it isn't "stacked" x4 memory.
Most of the 1GB modules in Pricewatch are the wrong kind for
you.
