Go to BIOS, under CPU configuration-->advanced Power Management, try disable EIST to see if CPU clock back to default frequency
I looked in the bios for your suggestion, but there was nothing like that there. The bios is a very basic HP UEFI. The only cpu options available were Overclocking: On/Off, Voltage, and Multiplier. But I found a program called ThrottleStop, and this is what things were looking like:
After fixing the Set Multiplier to x37, and unchecking EIST, the cpu is ramping up to 3.66mhz. Turbo doesn't seem to be working, but I can live with that. Is BD Prochot or C1E anything to worry about? Thank you so very much for your help so far.
