ThrottleWatch For Pentium M Processors

[Monroe]

I have a Thinkpad T-42 notebook with Windows 98SE installed. It came with XP SP1 but I bought it to get a newer notebook to run Windows 98SE. I had read somewhere that the Thinkpad T-42 was the last version that would run Windows 98SE ... but I am not 100% sure if that was correct. Anyway, yesterday I was searching around and came across this program called ThrottleWatch. I like how the Pentium M runs so much cooler ... on my Pentium III's I use Rain 2 to get a nice drop in temperature with using Windows 98SE. This little program might be of interest to some who also have a Pentium M and also a Pentium 4 and a Xeon processor for some extra information or just the throttle reading. It has a nice information display and works well with Windows 98SE. The website lists the version as 2.02 but I ended up with v2.01.

ThrottleWatch v2.01

Windows All

Utility for detecting and reporting the CPU throttling activity in Pentium 4, Xeon and Pentium M processors.

The amount of heat a CPU produces varies according to the processing load. In situations

of high sustained load (such as performance benchmarks, etc...), a CPU may produce more heat than the cooling mechanism is capable of removing and reach a high enough internal temperature to trigger throttling.

ThrottleWatch monitors and graphically displays both the CPU load and any throttling that occurs.

When ThrottleWatch is minimized, an icon is added to the system tray area of the Taskbar. The color of the icon changes when throttling is detected.

ThrottleWatch can also create a journal file for use with external data analysis programs such as Microsoft Excel. Pressing the F5 key alternatively starts or stops the journal.

Monitors and displays both CPU load and throttling of Intel chips. ThrottleWatch is a utility for detecting and reporting the CPU throttling activity in Pentium 4, Xeon and Pentium M processors. The amount of heat a CPU produces varies according to the processing load. In situations of high sustained load (such as performance benchmarks, etc.), a CPU may produce more heat than the cooling mechanism is capable of removing and reach a high enough internal temperature to trigger throttling. ThrottleWatch monitors and graphically displays both the CPU load and any throttling that occurs. When ThrottleWatch is minimized, an icon is added to the system tray area of the Taskbar. The color of the icon changes when throttling is detected.Types of CPU throttling:TM1: "Thermal Monitoring 1" throttling is a feature of Pentium 4, P4 Xeon, Celeron ("Northwood" or "Prescott" cores) and Pentium M CPUs. TM1 throttling does not reduce the CPU clock speed - it inserts idle cycles into the instruction pipeline to reduce the processing load on the CPU, which in turn lowers the CPU temperature. TM2: "Thermal Monitoring 2" throttling is a superset of TM1 and is used on LGA-775 versions of the Pentium 4 and Celeron processors and also on the Pentium M series of processors. TM2 reduces processor temperature by lowering the CPU clock multiplier and thereby the processor core speed.
