ThrottleStop

ThrottleStop is a voltage and frequency management tool for Intel CPUs (Core 2 and Core i CPU). Despite the fact that the program's functionality can be described in one sentence, you can think up quite a lot of assignments for it. The most popular application of ThrottleStop is saving laptop power and heat. That is, you can undervolt the CPU or lower its power limits and maximum multiplier so the laptop runs cooler and quieter and the battery lasts longer. Of course, your portable device may lose some peak performance, but everyday tasks are usually not affected. It should be noted that this program is designed for experienced users. A much simpler (but less flexible) solution for beginners is the standard Windows power plans.

ThrottleStop can also do the opposite: it can bypass throttling by disabling clock modulation, BD PROCHOT and similar mechanisms, and raise the turbo power limits (TPL) so the CPU keeps its full speed. This is usually done by enthusiasts who want maximum performance from a laptop. We strongly recommend that you do not change these limits without experience and a reliable CPU cooling system, and the developer advises checking that the power adapter is not overloaded! Another application of the program is lowering the CPU speed limits when the system is not sufficiently cooled. This helps reduce heat when a laptop runs too hot, for example on a soft surface or with a dusty cooler.

ThrottleStop supports the ability to create up to four setting profiles and quickly switch between them. The application also displays quite a lot of information about the processor cores, including the multiplier, the load of each thread and the current and maximum temperature from the sensors. It also includes FIVR voltage controls, Speed Shift settings and the built-in TS Bench benchmark. ThrottleStop is freeware written by Kevin Glynn and distributed by TechPowerUp as a portable ZIP archive that needs no installation.

ThrottleStop enables users to manage and control voltage and frequency of Intel CPUs, enhancing performance and prolonging laptop battery life.
