How do I achieve the overclock I want? i5 3570k - Page 2

Why would I increase offset to +.005? It's running at 1.38, I'm trying to get it down to 1.2. And my bios doesn't have a turbo voltage setting :S

You can't do it on Auto, because Auto adds some motherboard-specified offset and you have no way of knowing what that is. So it is doing VID + offset = Voltage - but with Auto you don't know either VID or offset. The only thing you can do on Auto is check the VID using Realtemp, you can't use the final voltage.

In other words, the offset in Auto may or may not be 0, and you have no way of knowing for sure. So if the VID is 1.3V and the actual voltage is 1.38V then Auto is actually the equivalent of a +0.08 offset (1.3 + 0.08 = 1.38), so if you put in an offset of -0.18 (to get back to 1.2V), the actual voltage you'd end up with would be 1.12V (1.3 - 0.18), which would be too low. That's why it's best to just pick an arbitrary offset to start with, and then you can easily adjust it to get what you want.

I tried +.005. It idles at .94 voltage, but it won't run prim95 blend at all: it freezes and shuts down right when the test starts. What do I do now? Thanks for all the help btw.

Try a higher offset until you can get it stable under load. You are really going to have to accept whatever idle voltage that ends up getting you, unless you just run it in straight Auto and take the high load Vcore.

Alright, I'll just keep experimenting. Thanks for all the help man, how do I give +rep?

ALRIGHT GUYS I FIGURED IT OUT! I'm currently stress testing 4.5ghz on 1.5v. The prime95 is blending, and I'm expecting failure, but we'll see. I understand everything now, thank you guys for all the help! Have a happy thanksgiving, and I hope you see some good deals on black friday! +rep to all!

No... Stop the prime immediately. You are throttling your chip.

In your bios there should be two voltages you need to tweak. The voltage you idle at is handled by offset voltage. It is a setting.. Take it off of auto and set it to +.010 because .94 is a touch low.. I prefer .97 for mine on idle. Then there is another setting that controls the voltage given at load it is called additional turbo voltage. Set that from auto to .025 check your load vcore by using prime. If it is lower than 1.2 than raise the additional turbo voltage. If higher than lower it. Should be very easy. Let me know what happens

1.5 or 1.2? 1.5 is very high.

Not all boards have a setting for additional turbo voltage - some just have the one offset voltage.

Any reason to beleive he doesn't? Did you ask? Because if he does have additional turbo voltage you should have had him using it instead of jacking up his idle and load voltages simultaneously. It also the only way to acheive what he is asking. If he does not have additional turbo voltage then he does not have control of his idle voltage as it will also rise everytime he increases the offset making attaining less than 1 volt difficult.

Because he said it didn't here:
