The MSI 6163 was one of the slower boards at 133Mhz although it was stable up to 152Mhz. This suggests that MSI have used less aggressive internal timings to ensure stability at these high speeds. Iwill BD100Plus maximum bus speed is 133Mhz. On paper the feature set is almost identical with all boards support bus speeds around 150-152 Mhz, apart from the Iwill BD100Plus , which tops out at 133Mhz. Out of all the boards with 4 DIMM slots, only the BX6-2 had the Texas Instruments Data Buffer present.
All boards offer the next generation of clock generators with many speed selections available.
105 and 110 Mhz put in appearances on the Asus P2B-F and the Iwill BD100Plus . The other boards opted for providing higher speeds. So these higher speeds offer some future proofing for overclockers. The Asus P2B-F failed to make the grade in any of the tests at 112Mhz, although it was better at 110Mhz. P2B-F was the fastest board on the 66Mhz tests, and also fastest on the Pentium III tests.
