Oh wow, this is awesome! Now, if you want to lower that voltage in order to see the lowest voltage that 4.5 GHz needs, then switch the Offset Mode Sign to a minus, and leave the offset voltage at 0.005 (so then it would change from +0.005V to -0.005V). At that point, you can keep decreasing it in -0.005 increments by entering 0.010, 0.015, 0.020, 0.025, etc. With the Offset Mode Sign set to the minus sign, this will drop the voltage more and more with each 0.005 increment adjustment that you make.
Also, I learned something about this motherboard a few days ago. If you were to leave the Offset Mode Sign as a plus sign and leave the offset voltage at +0.005 and only increase the Turbo Ratio (the "By All cores (Can Adjust in OS)" setting) from 46, to 47, to 48, etc., then the voltage will increase as well. So this is another reason to switch the Offset Mode Sign to a minus now. This will enable you to raise the Turbo Ratio beyond 45 while continuing to experiment with different negative offset voltages so that the voltage doesn't continue going higher and higher. It's already higher than 4.5 GHz should need, but it's still very safe!
So what you can do is find the lowest necessary voltage for 4.5 GHz in order to be fully stable, and then switch to 4.6 GHz and then see what happens to the voltage. It might increase just enough by itself (as I described above) in order to stay stable. Or, it may need a a higher core voltage. So for example, let's say you find that you need -0.025 for 4.5 GHz, and then let's say that you increase to 4.6 GHz and it's not stable. So then you'd switch to -0.020V and try again, or 0.015V if it's still not stable, etc. because that will increase the core voltage by shrinking the negative integer.
In other words, I'm very glad that this is working so far! Although, I'm not surprised because this isn't a bad motherboard at all. :)
Anyway, I am glad you mentioned this GPU Boost Switch: I didn't know about it! That has to be why there are no iGPU options in there. Nice. Less stuff in the way. hehe
Thank you for the update, Aleckazee! I wish you great success in finding the lowest necessary voltage for 4.5 GHz! After that, we can maybe to go 4.6, 4.7, or maybe even 4.8 GHz.
