X-bit Labs posted a review of the Asus P4B266 motherboard and showed a phenomenal 172MHz FSB overclocking results.
<< Aiming to find out how ASUS P4B266 feels at high FSB frequencies, i.e., to define the top frequency at which the board works stably, we ran the following test. We were lucky to find a Pentium 4 CPU sample with an unlocked clock frequency multiplier. We deliberately brought it down to 10x and thus could neglect the overclockability of the CPU itself. Then we took DDR333 SDRAM module from KingMax clocked at the FSB frequency in order to obtain the top of FSB overclocking abilities. These are the results of our experiments: (172MHz)
Yeah, 172MHz for the FSB frequency on a Pentium 4 based mainboard is a really serious thing. Nevertheless, ASUS P4B266 worked quite stably at this frequency. This high overclocking result gives us good grounds to draw some interesting conclusions. First, we can state with all the certainty that when Intel launches its Pentium 4 CPUs using 533MHz Quad Pumped Bus, they will surely work well on ASUS P4B266. Second, the overclocking potential of P4B266 is high enough to bring it the status of the best mainboard for Pentium 4 CPUs overclocking. It is also due to the support of DDR SDRAM, which is better overclockable than RDRAM. >>
