though I've tried 45x settings and had it running stable at that, I think 43x is a good balance of speed and temperature readings for me personally. Run with your new speed for a few days or weeks, just to make sure it's stable (i.e. At higher multiplier settings, you may need to tweak voltages up a bit to keep stability. Tips: Keep notes of every change you did to your system when exploring the 40x and above overclocking. You can still have a very stable and cool system up to 44x-45x with some work.īeyond 45x, the few extra points you gain may not be worth the hassle (and heat and risk). Now that you're running at 39x (3.9Ghz), I bet you'll be itching to find out how higher you can go. and not use the stock cooler that came with it. that's stupid.Īgain, why buy a K processor if you're not going to o/c it?Īnd if you buy a K processor, you better buy a decent cooler too. If you are overclocking with stock cooler, that's not risky. Get a decent $50 heatsink/cooler, it will be bigger, quieter, and will cool your cpu better. Built on the Santa Rosa platform, MacBook Pro now offers the latest Intel Core 2 Duo processors, memory up to 4GB, up to 250GB of hard drive space and high-speed GeForce 8 graphics in a stunning, lightweight, aluminum enclosure that is just. Of course, that's assuming you're not using a stock cooler. Apple today updated its MacBook Pro line of notebooks. Another easy tweak.Ĭons: None that I can think of. Also, change your RAM multiplier to 16x so you're running at 1600Mhz.

Almost any K processor will do 39x easily at default settings. otherwise, why did you buy a K processor to begin with?Įasiest overclocking tweak In Bios, you can change the default multiplier from 34x to 39x. 'K' processors), you might as well take advantage of it and overclock. Encoding and high cpu intensive tasks faster. Some people go overboard with extreme overclocking, just for their measurebation pleasure. My definition of overclocking is running above the stock clock frequency.
