hey, I have the 2.4a and can run it at 2.88 so you should be able to get that 2.4b much higher. try lowering your mem speed a bit first though, as you might be at the mem thresh hold already. also if possible on that board, try locking in the pci/agp at 33/66.then try increasing your fsb. sounds like something is holding that chip back, so start with that!! oh yeah increase v-core to max 1.75 first then turn it down a notch with every successful post till it freezes---then increase to last level.
