dell xps 15 9550 multiplier stuck at 15 1.48ghz. no matter what i do it wont fix it permanently. I have formatted and re installed current drivers. its a 2.6ghz processor and 3.5 boost. if i disable the speed step in bios it just holds at 2.6ghz and if i re-install "Intel-Dynamic-Platform-and-Thermal-Framework_74P16_WIN_8.3.10209.6897_A12" it will work normally up to 3.5ghz until I reboot. I have not found a way to make it work normally permanently however. any ideas?
the computer is still quite fast at 3.5ghz but at 1.48 its difficult to use.
