OVERVIEW: This project aims to provide a temperature dependent overclock function for AMD Phenom II black edition processors somewhat like the Turbo Boost function on recent Intel processors. SOFTWARE REQUIREMENTS: MSChart is _REQUIRED_, Please download and install it from (Microsoft Chart Controls for Microsoft .NET) http://www.microsoft.com/downloads/details.aspx?FamilyId=130F7986-BF49-4FE5-9CA8-910AE6EA442C&displaylang=en The control/monitoring GUI is written in .net, and uses the Microsoft MS Chart Component for the graphing. Until I find a version which clearly states it can be redistributed, it won't be part of this package. It’s strongly recommended that you have the AMD processor drivers and Cool’N’Quiet enabled. Even if you set the power profile in windows to “Home/Office Desk” or one of the other profiles that effectively turn it off. First, because the processors tend to run cooler when they are downclocked during idle periods, this results in longer runtimes when switching to higher clock rates. Secondly, I haven’t tested this driver without those drivers loaded, and its distinctly possible the BIOS, may not initialize all the P-States properly. Thirdly, saving power is good for the planet. OS REQUIREMENTS: This utility has been tested under Windows XP-32 bit and Windows 2003 64-bit, it probably will work under XP-64 or W2k3-32 bit. It may also work under 2000, all bets are off for Vista or above. HARDWARE REQUIREMENTS: This utility requires an unlocked Phenom II processor. This means it only works with the “Black Edition” processors from AMD. If the driver is built from source, it’s possible it may work with the original Phenom (the hardware detection logic will need updating). This driver has been developed and tested with an AMD 550BE, any other BE's may require further tweaking. Please post success/failure comments to sourceforge.

Furthermore, as with any overclocking utility, it is completely possible, it may destroy the machine or worse. Finally, this program doesn’t have any solid engineering basis behind it, as the author is not privy to internal engineering documentation about thermal envelopes, pipeline critical paths, transistor parameters, etc. INSTALL: Once the install completes, and you have MSChart installed, the application may be launched. It will immediately display "Driver is not started, please check the configuration in Control->Configure Driver." Click Control, Configure driver. Click the "..." and select either kdbm.sys or amd64/kbdm.sys depending on whether you are running 32-bit or 64-bit versions of windows. Then click install, and if it says success, close the dialog. You may then click "Control->Enable Graph". The Three settings for clockrate, voltage, and temp threshold may then be tweaked. When the graph is enabled they take affect immediately. Otherwise they are stored in the registry for the next driver load. BEHAVIOR: By default, the driver is fairly conservative, and only overclocks the processor by 100Mhz. The temp threshold is also fairly conservative, its possible if your cooling is poor that you may never see the clock boost. Messages about driver behavior may be retrieved with a utility like Dbgview. FUTURE FEATURES: For now there are two future directions: Multiple clock steps, the idea is that the cooler the processor the more it may overclock. Cool’N’Quite tweaks, for example on XP it might be nice to have an option to lock the core’s p-states together (like Phenom MSR tweaker). Furthermore, I think it might be nice to have operator dependent boosting (for example, if you click the mouse its an instant temporary clock boost, to increase responsiveness).
