    I read that when you turn overclock mode on the multiplier is set to 6x giving you 6x266 = 1600Mhz and some programs show the clockspeed as 6.5x266=1730Mhz.
    Well, I installed everest today and it shows 6x289 which also gives 1730Mhz with the supposedly correct multiplier.
    How can I be sure if the multiplier is 6x or 6.5x and if the bus speed is 266mhz or 289mhz?

    use cpu-z, it gives the true clock speed which is 1600 mhz

    I used cpuz too, but why is it more reliable than other programs? For me there's a 33% chance the true clockspeed is 1600mhz and a 67% chance it's 1730mhz given the 3 types of measurements. Unless there's a reason cpuz is right.

    I used cpuz in a cheap netbook and it gave half of the actual clockspeed! It's an atom cpu, I don't know if there's any sort of dynamic underclocking in it or if cpuz was wrong.

    because then some people pin mod their m11x's cpuz rises to the OC they reached, BIOS OC just reaches 1.6 Ghz sadly

    I would love to have my m11x @1.73 or more but its just 5 months old, though I can play almost any game out there

    Where you stressing the cpu? Intel speedstep lowers the multiplier on cpus to save power when theres not much cpu demand in your system. With the R1's when you set it to OC mode, it locks the multiplier on 6x and it'll never go up or down so it's always at 1600mhz.

    There's an easy way of knowing if it's set to 1,73Ghz or not. Someone with a pinmodded ICS PLL could benchmark it with the clock 6x289Mhz and see if the results are better or not than the stock overclock. If they are the same, then everest is right and the bus speed is 289Mhz, if not, it's 266Mhz.

    I think you're right and that was probably the speedstep, I'll check again this weekend.

    Unless you have pinmodded it the "stock" OC speed on the R1 is 1.6GHz, no ifs, no buts.

    In overclocking mode the multipler is locked at 6 whilst the bus speed is locked at 266MHz. Some applications don't understand this as the U4100/U7300 have a maximum multipler of 6.5x (and in non overclocked mode it will actually use 6.5x200 to attain 1300MHz).

    It is possible that you have a unlocked TME but unless you have done any SetPLL modifications you won't be seeing a higher FSB in the real world, in this instance Everest is simply wrong.
