Hi guys i' m new to overclocking, so i followed the guide from Gigabyte forum. I'm able to change the values in my Turbo Ratio (1 till 3-core ) without any problems but when i try to change the Turbo Ration of the ( 4-core ) all the values will change to auto on all 4 cores ... m i doing some wrong here, some advise is greatly appreciated tyvm

I'm using a  P67A-UD7-B3 mobo with an i7-2600k And am running into the same problem. Now If I just change the cpu multi,(withe Eist and the c functions enabled) it will ramp up just fine, but isn't that supposed to be the function of the Turbo ratio?

Unless I am very much mistaken this is a function of the CPU/motherboard and is to stop over driving the processor. I would advise reading up on the finer points of it though.

Your reply is much appreciated. I'm still puzzled though as trying to set the turbo ratio to 40 on all cores in Bios resets to auto for all cores.

Purely from memory but I think it only works up to 38.

ok, So If I want to use hihger clocks(when gaming) I should just use the cpu multi and leave my EIST an c states alone, depending on voltage and stability of course. I would like to have my rig throttle back when the the OC is not needed, to save power and $

Very informative Dark Man, thank you.

I've seen this issue as well.

In 'advanced' settngs, I ensured the topmost setting was 34.
For the 4 individual settings, I changed each one top-down. 

e.g. (40, 39, 38, 37 for 1-core, 2-core, 3-core, 4-core).

I then saved successfully.

Changing the settings at random did seem to cause "AUTO" to repopulate, which was weird.

I can say, for my board, GA-Z86X-UD4, upgrading to the latest BIOS (F9) resolved a number of other issues - for your board, did you update to the latest BIOS ver?

[tr4l1975]

Yes I did, and I check frequently to make sure it's still the latest. I just thought it was strange that I couldn't all 4 to the same value. I have since then just turned turbo off and running with a 40 multi 24/7 and am happy with that. I may try for more just to see the max stable OC, but I think 4-4.2GHz is fine. I really only play BC2 and BF3 anyway. Thanks for all the help.
