Microstar oc

my family rig has a Microstar VIA KT133 motherboard. i don't know if it is locked of not. I was wonderin of they ever overclocked in the first place. if so what is the max overclock.

First step would be to go into the BIOS and see what OC'ing options are available. If that is the KT133 chipset, rather than the KT133A, then you're not likely to have much success in any case, but that also depends on the particular CPU and memory.
