I was wondering is it still possible to overclock non 'K' sandybridge cpu's on a P67 mobo by selecting one of the turbo multipliers. In effect still getting an overclock but not as high maybe 3.7GHZ?
 
Yes you can get a small overclock that way, but it's hardly worth doing as it will turbo to that level anyway when its under load. Intel have done a very good job of restricting overclocking to the k range :(
 
i thought the turbo boost only happens when only 1 or 2 cores are loaded, I suppose what im asking is the max turbo boost is 3.7 so that equates to a 37x multi can u apply this full time as an overclock on a non k 2500?

As far as i know the multi on a non K chip is locked
 
Right i think i found the info I was looking for over on Anandtech.http://www.anandtech.com/show/4083/...-core-i7-2600k-i5-2500k-core-i3-2100-tested/3

It refers to a limited unlocked multiplier.

The turbo mode with 4 cores active will add 1 bin (multi). So on a 2500 non k this would be 34x.

100x33=3300 + the extra bin (multi) = 100x34=3400

You then have a further 4 bins (multi) at your disposal. So this would give a multi of 38 which would =3.8GHZ. Still not sure if you can lock this on or wether it just remains a turbo mode overclock

Does this make any sense????:confused:
 
If you have a locked multiplyer CPU the only real way you can overclock is by changing the BCLK. And that is very limited.
 
with the limited overclocking on non K versions you can add the extra 4 multi that is availabe with the turbo. so on a 2500 you would have 3700 then the turbo would work over and above that so you could have 3800 using 4 cores, 3900 using 3 cores and so on.

but you have to have a p67 board, it doesn't work on h67's.
 
so the 3.7 clock would stay and then turbo on top of that? By that i mean the cpu would run at 3.7 and then the turbo would take that to 3.8 if 4 cores active and if 1 core active u would get 3.7 + 4 turbo =4.1?

With a p67. got you thanks Chipps!

Thats not too bad if u aren't interested in the integrated graphics and one comes along at the right price. Not as good as a 'k' for sure but not a total loss.
