Hello, i've tried more than 10 solutions, like disabling speedstep from bios, i also tried uninstall both processor drivers, also tried many stress tests (CPU-z and hwinfo was used to monitor and for stress i used userbenchmark & intel burn test also tried to put load with applications and heavy videos but still i can get only 1.26 or rarely 1.27 ghz frequency on a dual core p8400 which is 2.26 ghz, im using a dell precision m6400, without battery, with a 110watt AC adapter. Any solution to this problem? i've seen many posts like this but none got solution to mine.
