This Core I5-760 turboboost feature capped at 22, not 25.
I've noticed my I5-760 only reaches 2.91Ghz instead of the expected 3.33Ghz. I see that Turbo-boost, especially the older version, can behave unpredictably at high temperatures. In the CPU Configuration section of the BIOS (my ASUS P7H55 model), it shows a maximum boost setting of 22, with a base of 21. I understand the turbo works when enabled, but if I disable it, the max drops to 2.77 instead of 2.91. When I first set it up, it performed well and exceeded 2.91, running smoothly. However, once I checked Task Manager, I realized the CPU wasn't utilizing the full boost potential. I missed the Multiplier setting until now. I'd appreciate any advice on how to restore proper turbo functionality. Thank you!
These initial processors function in a distinct manner from the second generation Sandy Bridge and modern Intel chips. The starting frequency scaling factor for an i5-760 is 21. To enable full turbo boost, you must increase this number by one. That equates to setting it to 22 (21 + 1). This adjustment doesn’t instruct the processor solely to use the 22x value. It’s the method to signal these units to operate at peak turbo capacity. Another important point is that maximum turbo boost typically appears only when a single core is engaged. The C states must also be activated within the BIOS settings. Many users prefer turning them off, but on these processors disabling C states can hinder proper Turbo Boost functionality. Consider using ThrottleStop to verify if C states are active or inactive while idle—it’s the most reliable way to see the multiplier in action. You can also tweak the multiplier via ThrottleStop without restarting, making it a useful resource for understanding these architectures. If you need clarification, share some screenshots from a TS Bench 1 Thread test. Excess background processes may trigger additional cores, which can stop the CPU from reaching its full turbo potential during a single-threaded evaluation. Most monitoring tools, such as Task Manager, lack precision for these types of performance metrics. https://www.techpowerup.com/download/tec...ottlestop/
