Ah, the first motherboard
to support DDR333(also known as PC-2700). Asus decided
to go with an SiS chipset for this motherboard, a company
who used to be known to be in value and oem pcs. Sis was
also known for their terrible performance and compatibility.
However, SiS has recently started to make some very good
chips, which are producing great performance, incredible
stability, and more affordable prices. The Asus P4S333
motherboard uses SiS's 645 chipset, which is SiS's first
chipset for the Pentium 4.
Until this motherboard came
out DDR333 was targeted towards overclockers, the motherboards
didn't support those speeds at stock(they used DDR266/PC-2100),
but when you overclocked it was guaranteed to run up to
333mhz (like how DDR433/PC-3500 DDR is now).
