    Hi, I have a clevo m770cuh. I was looking for a way to increase performance of my gpu and found this thread.

    I used amd gpu clock tool for the hd5890 or 70 and adjusted the clocks and undervolted gpu as well. Reading the thread led to this thread about cpu undervolting.

    I have a core i7 620m, rmclock doesn't work, nhc isn't for win 7 x64, and I don't know how to use throttlestop, so I found CrystalCPUID. I have heard that the core i3, i5 i7 are not able to undervolt (mobile versions) with software, but I thought I would try it anyways. I have played around with multiplier and voltage settings and it seems to work-decreasing my temperature without sacrificing performance. Anybody used this tool before and does it actually work for undervolting this type of processor. Thanks for any good replies.
