i7 Turbo - Tool to test for Turbo throttling

[unclewebb]

Movieman's X5560 was a little confusing until rge looked up the Intel specs for it and found this:

http://processorfinder.intel.com/det...px?sSpec=SLBF4

2/2/3/3 are the available frequency bins (+133 MHz)of Intel® Turbo Boost Technology that are available for 4, 3, 2, 1 active cores respectively.

With 4 cores per CPU active, it makes sense why he gets a +2 Turbo boost. With only 1 or 2 cores enabled in the bios, this CPU gets a +3 Turbo boost.

Intel doesn't have the docs posted for the W3520 yet so I'm not sure what its Turbo boost capabilities are. For the 920 and 940, it's this:

1/1/1/2 are the available frequency bins (+133 MHz)of Intel® Turbo Boost Technology that are available for 4, 3, 2, 1 active cores respectively.

A +1 Turbo with all 4 cores enabled is correct at full load for the 920 and it looks like the same is correct for the W3520. At idle with the voltage reporting 1.120, it looks like Speedstep is doing its thing so a CPU-Z reported multi of 22 is not correct.

rge has been doing a pile of testing for me the last few days and a lot of things are finally starting to make sense when it comes to multipliers. Intel deserves a because the publicly available documentation is horrible. Simple bits of information can't be obtained from reading 1000s of pages of manuals. A lot of it is trial and error.

i7 Turbo has a couple of minor bugs. When that's fixed, later tonight, then I'm hoping to look at the DFI 12 multi problem to see if anything is possible.
