A. The Intel 815 chipset series allow async memory operation; you could run
the memory at 3/4 the frontside bus speed.
B. The limit for Pentium III 'coppermine' CPU's is about 1.33 GHz with
overclocking (Pentium III 1B GHz 100 MHz nominal FrontSide Bus speed.
C. PC150 SDRAM is available, but why bother? The PCI bus will be way too
high with a FrontSide Bus speed of 183 MHz (46 MHz.)
