to receive a Mass Storage CBW 5, req->length must either be set to a value thats divisible by. So Android's comment is accurate about this behaviour, how it will only turbo boost when part of the processor is idle. Intel Power Gadget uses the Intel RAPL interface 31 to provide power and energy estimations of the core and uncore of the processor, together with the. The biggest part of the driver refers to the Gadget API. Here is a screenshot when I'm stress testing the cores: It appears that it will only turbo boost the cores when the load is not that large. The frequency will sometimes get boosted to 4.2GHZ maximum. However, if I put random loads on my cpu. Turbo boost is when your cpu core(s) throttle over the base frequency. Showing the single textual increase in frequency value as turbo boost. Note that the parameters for the log are based on the options set in the GUI. At the end of the script, call IntelPowerGadget.exe -stop and it will stop the logging. At the beginning of the script, call IntelPowerGadget.exe -start and it will trigger logging in the GUI. Only way this gadget shows the turbo boost? If yes then again they are To use Intel Power Gadget 3.0 in a script, first launch the GUI. Does the increase in clock frequency above the base clock is the So unless the only reason why my cores have independant frequencies is because it's newer, your CPU should be working the same way mine is. Here is another interesting screenshot where 3/4 cores are at different frequencies, but the CPU load does not really match that perfect.īoth our CPUs have Idle States, Intel® Turbo Boost Technology, and Enhanced Intel SpeedStep® Technology. The cores throttle based on system load, as clearly seen in the first screenshot:Īs you'll notice, CPU #2 is at 9% load, and because hyper-threading is enabled, it corresponds to Core #1 which is at a much higher frequency than all the other cores. This is probably intel speed-step working, (since naturally you cannot set individual clocks for your cores). My doubt is that whether the dynamic overclocking occurs for allĬores together or each core is dynamically overclocked at differentĪccording to my monitoring program, the cores in my CPU have independant clock frequencies of eachother. +++ -376,7 +376,7 static int ast_vhub_epn_queue(struct usb_ep* u_ep, struct usb_request *u_req, Please refer to README for more details before you start using AMD Power Tool.
