voltage constant/offset/adaptive

post #1 of 4
Thread Starter 
I am running an intel i5 4670k on an asus z87 plus board. I am stable at 4.3 with 1.25v set at manual. Trying to go higher but I have voltage questions. This is a
24/7 computer. Im going to try for 4.4 but before i do so i have some voltage questions. Once im stable at the clock speed I want should I change the volts to negative offset? Im new so please be nice. Im learning. Here is the reason im asking. When the computer is at idle dont I want the voltage to drop since it is not needed? Would offset or adaptive be better? Im using real temp with ibt and aida 64. With ibt my highest temp on one core reached89 and the rest were low 80s. Im using coolermaster 212 plus. In my bios i have vcore set manual with 1.25. Cach ratio set to min/max 35 and vrid set to disabled. Bios suggested turning off if overclocking. Like I said im still learning. Recap

1. Aftwer stable do I leave vcore at manual, offset, or adaptive?

2. Anything else in the bios I should change?

Once you have a stable overclock, why not try enabling the low power C states? I like using a fixed voltage, the Windows high performance profile and the C3/C6/C7 C States. When your CPU has something to do, it will be receiving a fixed voltage so it is stable and when it has nothing to do, it will automatically drop down into C7 where voltage is reduced to virtually zero. This is the best way to minimize power consumption. Haswell showing an idle voltage under 0.700 V looks great but you might as well have your CPU cores at zero volts when they have nothing to do. With each CPU generation, Intel has improved their C State technology but many enthusiasts continue to avoid using them.

You can use RealTemp T|I to monitor the C States your CPU is using. Even when your CPU is partially loaded, the unused cores will drop down into C7 which reduces power consumption and CPU heat.

I never knew about this. Im looking at my bios under power management. I will set all c states to enable. However should i set c6 and c7 latency to long? Im guessing long

If you use CStates, combine with offset Vcore to get the Vcore to scale with the Frequency. Otherwise the vcore will remain static whilst frequency drops.
