272MHz to 299MHz is a fair increase in bus speed to not have to change any voltages at all. Not to mention the stock for your CPU is 266MHz not 272MHz.

I'd imagine its your RAM crapping out if you haven't given it any more voltage, as the CPU "should" be able to do 299x7 (2.1GHz), although it might want an extra 0.05v.

Anyway, try knocking your RAM voltage up a notch or two, or alternatively knock down the ratio to slow the RAM down a tad.

Sorry m8 this is still abit new to m8 is there any guides to follow for my setup
