i7 3770 non K OC - Page 6

You might want to reduce the offset voltage you are using. Those +0.200 V in your third screenshot are pretty high. I bet you could try to use something very close to zero for your offset voltage at 4.1GHz. Intel tested your CPU in the factory after manufacturing and configured your CPU's voltage settings so that it runs stable at 3.9GHz, and 4.1GHz is still pretty close to that.

hello friend, thanks for your help.

And what voltage do you think advisable? 0.100, 0.150?

thank you

If you don't want to struggle with experimenting, +0.050 V would already be enough. If this runs stable, you could then try to find a lower setting that works. I think there is a good chance that +0.000 V will also work fine.

There's also another setting that does something to voltage called "load line calibration" = "LLC". When overclocking with offset voltage, you typically want to put LLC for core voltage to something like 50%. How it's exactly named for ASUS, I don't know. On other boards, I have seen settings like "level 1, level 2, level 3, etc." and "standard, low, medium, high, turbo". You would choose whatever seems like it is in the middle.

If you set LLC like mentioned, it is very likely that your CPU will run stable with +0.000V offset. My CPU starts to need some offset voltage at 4.3GHz. The +0.200V you used in your screenshot, my CPU needs that for 4.7GHz.

Hello friend.

I tested here, the lowest number that my motherboard accepted was 0.060. Unless it could not define. Strange huh?

I have no idea what that means. tongue.gif

You can check what actually happens to the voltage from within Windows. Use the software HWINFO and open its sensor window. Here is what to look out for:



Those "VID" values at the top of the screenshot is a number that the CPU itself sends to the outside, to the motherboard. The "Vcore" value at the bottom of the screenshot is the actual voltage that the CPU gets from the motherboard. If you compare VID and Vcore, you will see what your motherboard is doing. The difference is the offset.

something more if you are interested (Click to show)
VID is not a fixed number. It changes depending on what the CPU is currently working on. It goes down to save power and keep the CPU cold. HWINFO shows four numbers for four cores, but it is really only a single number for all cores together.

If you use offset overclocking, what you are doing is adding that offset to the VID value the CPU wanted. If something stressful runs on the CPU, the LLC setting will also play a role and voltage will get reduced depending on what LLC is set to.

Look friend,

I set the vcore 0.040

If your PC runs stable, I would leave settings like they are now. It would be great if it works with that somewhat reduced Vcore, makes things run a bit colder. biggrin.gif

If you find that you see strange program crashes in programs that usually run without crash, or you run into Windows BSODs, just increase offset and it will go away. There's no other secret that fixes it other than more voltage.

Friend, looks like I left now, I downloaded more vcore. v0.020

I appreciate your attention and patience to explain me and teach me.

Pardon me for my bad English.

Hyper PI teste! smile.gif

On these CPUs, you need to enable C3/C6 to access the highest single core multiplier. You can check this by downloading the RealTemp T|I edition from my sig. Click on the C States button while your CPU is idle and post a screen shot of that. Using Hyper PI, try running a single thread and watch the multiplier in RealTemp. It will show you if you are accessing the max multi during this test. The non K CPUs work a little differently than the 3770K,
