Check this under Control Panel/Hardware and Sound/Power Options. When this disappears, the new power profile should already be selected and in use. A pop-up window will very briefly appear, indicating the command is running.Navigate to the 'addconfig.cmd' file, right click on it and select 'Run as Administrator'.Extract the zip file to the C:/ root directory.So, we created an additional power profile (Vista/Win7 only) which you can switch to/from at any time, even while applications are running.ĭownload the 'audio-power-settings zip' file and follow these instructions: But, you might be putting your computer to other uses where these features actually help. So, how do you avoid all this trouble? As a PC-user, you could go into the BIOS and explicitly disable these features across the board. So, if your FireStudio, or other FireWire interface, is not working correctly, even though you have a nice big Intel Core i7 processor, this might be the reason. While this can raise performance of single-threaded applications by up to 10%, the switching causes delay, and therefore crackles/dropouts.Īll of these delays can additionally hurt internal bus communication, causing, for instance, issues with the FireWire bus. Turbo Boost: enables internal overclocking of individual cores/CPUs, while at the same time shutting down other cores (keeping temperatures safe).
This also leads to delays on parking/unparking, causing crackles and drop-outs. Core Parking: disables individual CPUs (normally the virtual hyper-threading ones) and is used for OS-based multi-core-scheduling.While this may not hurt performance directly, waking those CPUs to full power takes time, leading to processing peaks and crackles/drop-outs. Speedstep and the C-States (C1e, C3, C6): allows disabling or throttling of individual CPUs.The following are descriptions of these features and their effects:
These features include Speedstep (EIST), the C-States (C1e, C3, C6), Core Parking, and Turbo Boost.
However, these features actually have a negative effect on multi-threaded applications that work near system time, such as Studio One and other DAWs. With Windows Vista and Windows 7, these features can be used to great effect, and some of them also improve performance of single-threaded applications. Newer CPUs (Intel Core series and others) offer a variety of power-saving features. Optimizing Windows Vista/7 Power Settings for Studio One
