The Tech Zone heeft een klein artikeltje over een naar 800MHz overgeklokte PIII:
The Alpha P125 was adapted to the Pentium III with two 60x25 fans that spin at 6000 RPM. L2 cache spacers were used to cool the L2 cache. Click here to see how to install a P125 to a Pentium III.
The stock heatsink on the Xentor 32 SE was unchanged but I added a Globalwin CPM 16 fan to cool it. This combined with the card cooler allowed the Xentor SE to run at 200Mhz core 250Mhz memory!
The system will run on the 153Mhz bus (920 MHz !!!) with Pentium III L2 cache disabled and a Voodoo 3 2000 PCI because the AGP TNT2 Ultra crashes with the 153 MHz FSB. However, Windows 98 is very stable (Word, PhotoShop, Dreamweaver). It just that PC locks up after 1/2 hours of intense gaming. Oh well, I can live with "only" 800Mhz.
