Could comment on how you are setting Vcore on your Hero motherboards?

Is it manual voltage? Or adaptive?
LLC used?

Thanks.

Manual voltage, set a bit under what we state. LLC is on auto (LLC 5.)

Is the reason you set the voltage lower than what you state on your site just for a slight cushion?

If I may interject, there are many variables even if you use the same motherboard each CPU is different and Silicon Lottery just flat out cannot invest the time into fine tuning the CPU overclock as we can.

Besides each CPU being different the user may be using better cooling than was tested with and going deeper into the BIOS settings.

The lower base voltage you use to stabilize the overclock the longer the CPU will last, that coupled with the lowest LLC you can get away with.

My Hero board is set on LLC 5 which seems to be working very well for my 7700Ks 5.2ghz overclock at 1.380v. (But I am also running at 10c coolant temperature using chilled water cooling.)

Margin to your specification is good. You want customers with different motherboards and cooling to be happy.

Basically this.

Understood. Are there temperature requirements for your bins? Like my current chip pre-delid hit 4.9 ghz but at the cost of like 95C. Are you binning with temperatures in mind as well? Certainly I understand a delid can help, but I'm wondering what you look for in temperatures.

Agreed, and I personally want not only a chip that clocks well but uses low voltages/stays cool. I can do the delid myself as I have the tools, but my current chip requires 1.35 just to do 4.9 GHz which makes me sad.

We don't have temperature requirements, besides under TJMax of course. A very rough range of peak core temperatures after an hour with our 7700K bins: 84-96C for the 5.2 bin, 80-92C for the 5.1 bin, 76-88C for the 5.0 bin, 72-84C for the 4.9 bin.

Of course each CPU is different, and can easily fall outside of this range. Take into account ~15C or so less when delidded, which is why we strongly recommend delidding on Kaby Lake. Delidding takes care of temperature concerns.

Newb overclocker here. Just upgraded to an i7-7700k on an rog Z270 motherboard, looking to overclock my chip. I know the basics I want to know what recommended voltage and speeds to run it for ever day so I don't burn out my chip. Also interested in learning about adaptive mode, since I don't want to let my chip run on high voltage all the time.
Thanks for the help!

A good rule of thumb for 24/7 usage is to stay at 1.45V or less.

As far as adaptive goes, just set the voltage you want under the "additional turbo voltage" field. This is the voltage that will be applied when your CPU multiplier goes above stock.
