locked multiplier? x21 in bios, x22 in cpu-z

post #1 of 4
Thread Starter 
as stated above, the multiplier for my 860 seems to be showing 2 different numbers. 21 in the bios, and 22 in cpu-z. my bios will not allow me to change the multiplier. only reason this is a problem is because I was at 4.2 @ 1.28 v on x21 multiplier in cpu-z, but now in x22, i cant seem to get any stable clocks above 4.0 without pushing vcore up to 1.4 or higher (which i dont want to do)

I have read on here to check that turbo mode is enabled, and as far as i remember ( i am at work ) it is on.

any other suggestions?

Turbo mode is an Intel feature which makes you CPU run faster when under stress. This is achieved by changing the multiplier.

If you have Turbo mode on, the multiplier will go up and down dynamically and would explain your issue. If you want to stay at 21x always you should disable Turbo (makes multiplier go up) and SpeedStep (makes multiplier go down).

that was the ticket, thank you. +rep

got a pretty good clock going finally.

weird thing was it was working at x21 mult with turbo mode on a while ago, but decided to change i guess.

here's what I have so far....

Im glad you found a solution! BTW I mixed up SpeedStep and C1E. SpeedStep doesn't lower you multiplier automatically (it lowers it when you computer is in sleep mde), it's C1E which dynamically lowers the multiplier.
