If you have hyper threading enabled and it samples 7 of your threads at a multiplier of 21.0 but the eighth thread has dropped down to 20.0 by the time it gets sampled, then it will display 20.875 showing that the Turbo was mostly enabled during that sample period.

At full load, if either multiplier starts to drop, that is an excellent warning sign that Turbo throttling is starting to occur.įor the MSR based multi, I am sampling it once per thread per second to improve its accuracy. On a Core i7-920 at full load with the Turbo fully engaged, both the Calculated Multiplier and the MSR Multiplier should be firmly locked on 21.000. This method tends to be extremely precise when the CPU is fully loaded. The advantage of the calculated multiplier is that during a one second sample period, it can be used to very accurately calculate the average multiplier during that interval. The Intel Turbo White Paper outlines this method:
The second way that Intel recommends is to compare two high performance internal timers within their CPU and then to use that information to calculate what the multiplier is.

If software only reads this value once per second then it can miss what's really going on. This gives you a snapshot of what the multiplier is at that particular instant.
The typical way is to read a model specific register (MSR) within the CPU. There are two ways to read the current multiplier from a CPU. Software that only samples your multiplier once per second might completely miss this problem. When this first starts to happen, not all software is able to detect that your multiplier is intermittently dropping down to 20.0. Turbo throttling can occur at high loads where the +1.0 Turbo boost will start to rapidly cycle on and off hundreds of times a second as you approach the TDP limit. With a 920, even if a bios lets you select a multiplier of 21.0 directly, internally it is still using the Turbo feature of your CPU. The multiplier for a Core i7-920 is typically 20.0 and if Turbo mode is enabled, you get a +1.0 boost for a total of 21.0. If you are using the Turbo feature of a Core i7 processor, it's a good idea to make sure that your motherboard properly supports this feature. Most motherboards allow you to turn off TDP based throttling in the bios but not all of them do and not all bios versions work correctly.

Microsoft Windows Vista Service Pack 1 & 2.This tool is designed to test for Turbo throttling which can occur on some X58 motherboards when overclocking at high load levels as you approach the TDP limit of your CPU.

The amount of time the system spends in turbo boost will ultimately depend on workload, operating environment, and platform design. While Intel® Turbo Boost Technology availability is independent of the number of active cores, the operation is dependent on having headroom (cores operating under TDP) available in one or more cores. What factors influence Intel Turbo Boost Technology operation? Once installed Intel Turbo Technology monitor, it will provides windows gadget interfaces called Intel Turbo Boost Technology Monitor, which provides simple display of increase in processor frequency when applications request while Intel Turbo Boost Technology delivers more performance.
When the Intel Core i5 or Intel Core i7 processor is operating below these limits and the user’s workload demands additional performance, the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached. Intel Turbo Boost Technology Monitor, Intel core processor utility that utilizes Intel Turbo Boost Technology to run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the Thermal Design Power (TDP).
