Windows 10: New version of ASUS AI Suite that works with KB4056892 availabe

You can take a look at this: The Coffee Lake Overclocking Guide

But better would be if @essenbe, @Dude or @doorules answer your questions, as the have ALOT of expertise on this subject.
Plus I'm still new to using the ROG BIOS, which has way more fine tuning settings than my ol MSI board had.

I used a tutorial from der8auer on my Maximus X Hero board, as a baseline, then made some fine adjustments for my Vcore and the C-States, I prefer to have them all on, including C1E, to save not only energy in idle states, but also keeps the cores not being currently used cooler. To turn off C-States, all I have to do is switch from Balanced to High Performance in power options in the control panel.

I think you covered it pretty well Cliff, and have him set in the right direction. I think I can be safe in saying that the vast majority of people who O/C do so from the bios and not in Windows. O/Cing from windows is just asking for a headache.

Get to know your bios, and when it comes to an Asus bios don't be afraid to ask questions. I can assure you that most people when they first see all the options in an Asus bios can feel overwhelmed. Take your time and do things in small increments. Trial and error is still a very valid learning tool IMHO.

 

Thanks to both of you for the advice. Although everything is running great with the AIS3 overclocking and temps are really low, I really rather learn about the bios overclocking. CPUZ currently looks good but not sure if software overclocking is even accurate.

 

I would find it difficult to give better advice than Doorules gave. As stated, most overclockers would never trust a piece of software to overclock and make changes to their BIOS. Don't feel overwhelmed at all the options in BIOS, most you will never use. Learn the ones you use and what changes they make. Go very slow in small increments, testing between each change. To do it right takes a lot of time and patience. Don't be afraid to fail. That is how you learn.

 

I think it was essenbe that told me(or was it Dude?) that software overclocking in windows is not so good, because you cannot trust the Vcore shown, or was it something to do with Vdroop on voltage overshooting?

Any how I recommend you make system images of your system with out a software OC(as opposed to a BIOS OC) in case you over do it and cannot boot back into Windows. Also if you want Windows to boot and have the OC, then use a safe one at the most, then up it when you need more power, but don't set it to start at boot, or you could have a problem getting into windows, or your system can freeze as soon as it gets to the desktop and you have now way of fixing it, as your keyboard and mouse will not function.

The real advantage of a BIOS OC is if it can get to Windows your ok, not necessarily stable, but can use keyboard and mouse, it you pushed it a tad too far.
And if you can't get into windows, just use your PCs reset button and F2 into BIOS and revert the last change.
And if you really screw up, there is always the BIOS reset button(on the Maximus X) or jumpers.

There is nothing to be scared about, as the newer chips since Skylake have really good fail safes built in.

I once ran my 6700K on one single core with hyperthreading turned off, and was able to get 5.1882 GHz and was even able to use all the UWP apps, including Edge. But I could not get back into BIOS as the OC was too high, but would always boot back into windows. It scared the crap out of me until I thought to use the BIOS reset jumpers with a screwdriver *chuckle
