You can pretty much just set the base clock to 160 and you're good to go. Might have to disable turbo boost, but worth trying both ways. Leave the voltages at auto unless there's some issues cropping up. Also, check that your RAM frequency is at whatever it's supposed to be since increasing the Base clock will also increase the RAM freq. At most, you might have to increase the VTT voltage a tad, but again, on AUTO it should work ok.
