i7 Turbo - Tool to test for Turbo throttling

[unclewebb]

road-runner: The calculated multiplier is not 100% accurate at idle so when running LinX, you might need to crank up the Load Filter in the top right corner to prevent low CPU load from screwing up your calculated multiplier Miin/Max results. LinX drops the load between each round.

In your screen shot, the real time calculated multiplier in the top left corner shows a steady 21.000 when your CPU is at 97+% load so no Turbo throttling is occurring.

Here is 003's example:



At 99.59% load, the calculated multiplier has dropped down below 21.000 to 20.875. That's usually the first sign of Turbo throttling. This example also shows that the calculated minimum multiplier is 16.370 which might be a sign that EIST is not fully engaged. In Windows Vista, if you want your multiplier to drop down to 12.000 at idle then you need to reduce your Minimum processor state to about 50%.
