Oveclocking a AS ROCK Motherboard HELP!

Hello and thank you for coming in! I need some serious help. I have been overcloking for a few months and I would like to think on this I have passed newbie stauts. However, I do have an asrock p4v88 motherboard that will not overclock very much. I am trying to overclock a celeron 2.4 (not d). The clock multipler on the chip is locked. So is the cpu voltage core settings. All I can do is move up the fsb I believe. I can get it from 100 all the way up to 112. After that it will not post. To computer I have a jetway motherboard with the same chip that overclocks to 133 fsb! and the jetway is considered older with a much older chip set. Here is the specs that would effect the overclock....fan is a big coolermaster rated to 3.8 ghz. Ram is rated pc 3200. Anyone have any ideas???
