Try to push the FSB up to 166MHz and see if it runs stable..
If it does, which it should, you'll be running at 2700+ speeds, which is 2.167GHz.
However, I'm not familiar with that motherboard. If it doesn't "officially support" 166MHz FSB, doesn't have PCI lock, or doesn't have AGP lock, you probably want to stay away from increasing the FSB.
