ThrottleStop 5.00 http://www.techinferno.com/downloads/ The latest version supports the new Intel Ivy Bridge CPUs. It is shocking how many poorly engineered laptops are sold every day that randomly throttle on a regular basis when gaming. The ThrottleStop Log File option will let you see what is causing the slow downs. If you see the multiplier in the log file suddenly drop to the lowest value, that's a good sign of throttling. Also keep an eye on the 2 different clock modulation columns in the log. Clock modulation should always show 100.0%. Anything less is a sign of throttling. Throttling is a common problem among all major manufacturers. You have to do your own stress testing because of the dishonesty in the market. Send the author of ThrottleStop (ME) an email if you need some help understanding the data in the log file.
