The i9 of the XPS has a power limit of 56W permanently (please correct me if I'm wrong), or 78W (short turbo boost period). Something is going to be glowing in red. When 2 cores are active, the maximum drops to 18 and when 3 or 4 cores are active, the maximum multiplier is only 13. This means when 1 core is active and the other 3 cores are asleep, that core can use a maximum 21 multiplier as long as it is operating within the turbo TDP / TDC power limits. I have power limit throttling issue with my Notebook HP Pavilion 17-ab313ur. Joined: 4 months ago. Hi there! Open up ThrottleStop Limit Reasons when testing.

If you want hit constant 4.0ghz without power limit throttling, I don’t think there’s a solution yet. With this in mind, and the decent cooling performance available, I’m wondering if using throttle-stop to limit the power/current throttling would be possible. The Clamp option will force the CPU to throttle as much as necessary to prevent the CPU from exceeding the turbo power limits that you have set. Power Limits. When performing lightly threaded tasks, Turbo Boost kicks in, pushing the clock speed too high, making the temps shoot to 85C+. Some manufacturers use this third set, many do not. Open | Hardware.

That is your reason for throttling. Each setup has energy governance for while plugged in and on battery: Posts: 2. Each of these downloads are specific to the CPU listed and come pre-setup to optimum undervolt, Speed Shift EPP, power limits and other various tweaks. 2 is true, when i change the speedshift max and min to the lowest number which is 1 in the Turbo Power Limits tab in ThrottleStop, why is my core limited to the lowest clock speed (800 MHz) 4. Change Long Power Max to 45 and Short Power Max to 60. Next up is the four select-circles at the top left.
