I have found an unusual issue with ThrottleStop Kevin. ThrottleStop presently supports Core 2 and Core i7 mobile CPUs.

This version will expire in a couple of weeks so I hope I don't have to add some nagging messages to the next release of ThrottleStop. If this simple program dramatically improves the performance of your laptop then consider donating $5 bucks to encourage future development. On a T7200 I was able to lower the core temperature by 20C while running Prime by simply adjusting VID lower. It's a good idea to run Prime95 Small FFTs or similar when playing with this setting. At full load, only lower VID one step at a time or you might lose stability. This new tool can fix both of those issues plus it has the ability to set half multipliers on 45nm Core 2 CPUs, enable Super Low Frequency Mode (SLFM) as well as adjust voltage ID on the fly. Some laptops also throttle back the CPU multiplier which can also significantly reduce performance. There is a significant problem on many Dell laptops where Clock Modulation is used to slow down the CPU internally without warning users about what's going on. The C-States program and idea kind of died but it has been replaced with a program called ThrottleStop. I like the possibilities but I need some positive feedback before deciding how much effort to put into this new project. My plan would be to support Core 2 mobile CPUs including the 45nm series like the P8400. You would save a lot of power and battery life when watching a movie or whatever without sacrificing any performance. I didn't run a gazillion hours of P95 but it was obvious that this CPU is capable of running reliably at full speed without needing anywhere near the default voltage. I think most laptop users could appreciate a simple app that gave them this much control. In under 4 minutes, Core 0 had dropped 20C from its maximum of 86C down to 66C with this one simple tweak. One thread of Prime95 was still running as I dropped VID lower and lower and lower and look at the results. I adjusted VID as low as it could go and I ended up at a VID setting of 1.0625 volts. When running a single instance of Prime95 Small FFTs, the core 0 temperature was up to 86C.ĬPU-Z doesn't report the actual core voltage for this laptop, just VID, so actual core voltage was likely slightly less than that due to vdroop. I'm not yet sure what's possible but I did some testing tonight on a T7200 which uses a VID of 1.2750 at full load. I've been thinking about combining a few of my tools into a new program to give better thermal control over laptop / mobile CPUs.
