Não me fiz entender... a board (P4G8X) estava a funcionar a 200 Mhz FSB.
200 MHz FSB (Dual DDR400) / HT Pentium 4 3.00 GHz (3000 MHz 12-8/512 KB)
A velocidade máxima (teórica) do chipset 7205 é 133 Mhz FSB.
The Intel® E7205 chipset represents the next step in entry workstation chipset technology for the Intel® Pentium® 4 processor. The Intel E7205 chipset design provides a compelling transition to next-generation workstation-class technologies by delivering support for Hyper-Threading Technology along with maximized system bus, memory, and graphics bandwidth.
Features that Maximize Performance and Balance the Platform
Intel® Pentium® 4 processor with 512KB L2 cache and a 533 MHz system bus provides up to 4.3 GB/s of bandwidth between the processor and the chipset.
Dual DDR266 memory channels provide up to 4.3 GB/s of memory bandwidth, which exactly matches the system bus bandwidth.
The direct attach AGP 8X port provides 2.1 GB/s of graphics bandwidth directly out of the MCH.
The ICH4 provides advanced features, including Hi-Speed USB 2.0.
Pelo que se entende do artigo, até aos 200 Mhz é possivel fazer o o/c... dai para a frente, como calculas, são muitas variaveis e tudo é possível... ou talvez não.
