    Hi all,

    I am curious on how to learn how to overclock the CPU (Intel Core i7 2670QM) as well as the GPU (AMD Radeon HD 7690)? Specifically, I will be using my newly ordered Y470P.

    In addition to overclocking both CPU & GPU, is there any 'danger' by doing this which could make those components fail? Obviously there is risk, but in a real life situation, if you overclock too high, the components will just overheat, correct?

    I don't want to get too crazy with this, just want some stable overclocking capability to get me a leg up. Plus, I've never done it on any machines before so it should be a good learning experience.

    Thanks!

    You can't overclock the CPU, since it's a locked sandy bridge CPU.

    The gpu can be software overclocked by MSI afterburner most likely. I'm not sure about the ati mobility 7xxx series since they just came out and AMD has not released any new drivers on their website.

    What exactly are you using your laptop for that would benefit from overclocking? Laptops generally aren't very overclockable because with higher clocks (and voltage), power consumption can jump quite significantly and since there is limited space and ventilation, the heatsink/fan will not be able to get rid of the heat fast enough, thus resulting in physical damage to components. Most likely your laptop will have a single radiator with heat pipes connecting the CPU and GPU together, thus when you mess with either, stability of the other is affected.

    You're more than right. I'll wait until I'm set up with the new laptop & advise if help is needed at that point. Thanks!

    The benefit from a slight (ie +60-90 MHz) bump in the clock speed has a benefit of raising the FPS by a handfull, which is what I want to do. It shouldn't affect the temperature very drastically. And as for power consumption I'm sure it would raise it, but when not plugged it the lappy uses the Intel HD 3k. Although this will shorten the lifespan of the hardware.

    Our laptops are currently un-overclock-able because the drivers haven't been released yet.
