I'm not familiar with that board in particular, but the issue with many motherboards not meant for overclocking is that the VRMs on the motherboard that supply and regulate voltage to the CPU may give out and burn stuff up. It'll help if you can keep them fairly cool. Just raising the frequency shouldn't put too much extra strain on them, but it's something you'll want to keep an eye on if you raise voltage much at all. If they don't have heatsinks on them already, you might see if you can stick something (generic little RAM heatsinks with the double-stick tape might not be a bad option) on them and/or position a fan over them. It's normal for them to be quite hot to the touch, so it may be hard to judge if your motherboard doesn't have a temperature probe near them.
I'd recommend looking up what wattage of processor is supported by your board and comparing that against the CPU section of power supply calculator
such as this one. You should have a little headroom over what it's rated for, but this is seriously at your own risk.
Edit: Looks like you've gone from 77w stock to 86w assuming you haven't changed voltage (or your mobo hasn't changed it automatically).
