Intel 2500k OC

'ADJUST CPU RATIO' is where you set the overclock speed.you cpu freq is 100.therefore x33 is 3300 Mhz.if you set 45 for the ratio you have 4500 Mhz.(don't do that all at once, of course)The step by step method, testing each step using the utility before going to the next step, is the safe way to proceed.first up the cpu core voltage to 1.35.set the ratio forward 1 at a time 34,35,36,... 46.Test after each step, about 15 minutes for the first steps.As you get to 40 and above test longer each step, an hour!A long test but its the safe way.I would not go over 46 without a more exacting procedure tutorial and understanding the tutorial.The test = running a recognized overclocking test utility and studying the result of the test, each step.1.375 voltage is where I ended up, after first starting with 1.35 to do the step by step tests.http://www.clunk.org...-beginners.html
