Some CYRIX and IBM "Pentium" (6X86 P200+) have a system bus clock specified with a 75 MHZ bus clock --> no system bus overclocking The potential issues are in the system bus/PCI bridge : - If it supports a division ratio > 2,27 (75/33) --> No problem - If it is fixed to 2 (most INTEL chip-sets) -->PCI overclocking Regards N.L.C.
