Loads of mainboard makers try to follow ASUS with enabling the Performance Acceleration Technology on i865PE-based mainboards in order to compete with the largest mainboard manufacturer. As we understand now, it is hardly difficult to enable the technology on the chipsets that do not officially support it.
Albatron, ABIT and Chaintech have reportedly released new BIOS versions for their i865PE mainboards that enable certain memory performance optimizations that increase the speed dramatically. I now think that these optimizations have the same nature as Intel’s own PAT, however, since Intel denies using this brand-name when referring to its mainstream products, mainboard makers do not state the they actually enable this feature.
