i7-8700K overclock cooler

I purposely did not quote this statement in my first reply because Gamer Nexus was not exactly incorrect, but you'd have to thoroughly read his comments to see he was testing the "Multi-Core Enhancement", feature in the ASUS Maximus X Hero motherboard BIOS.

Gamer Nexus was incorrect. The i7 8700k turbo boost is 4.7ghz and it does it on all cores. The i5 8600k(mine) turbo boosts to 4.3ghz, though mine is overclocked to 5ghz.

Also you would want to get something a little beefier then the hyper 212. The 8th generation cpus run on the warm side.

This is one of my recommendations.

If you can't afford that I would recommend this.

I'd like to know the source of 4.7Ghz Turbo Boost on all cores. Every site I looked at including Tom's Hardware and Anandtech say 4.3Ghz Turbo Boost on all cores. 4.7Ghz is only listed for one core.

When a reviewer picks a certain feature to do his testing with it can only be a solid conclusion across the board if all the other motherboards have that same feature. Because does that specific feature automatically affect the stock specifications of the CPU being tested, please consider that.



Since this is the overclocking section and the OPs opening question is regarding overclocking his 8700K, and even though his request is a very small overclock, the stock aspect can seriously be affected when it comes to manual BIOS settings. So the argument you are pursuing is not a cut in stone answer simply because a simple BIOS adjustment can change how the CPU cores come into play. Also if the application being tested is single threaded there's no need for the other cores to be pressed into action except for maintaining background necessities. Muti-core capable applications being tested also rely on their core use capability of what the application is capable of actually using core wise. However when overclocking comes into the picture and you affect the specifications of the CPU anything is possible in the realm of how many cores are active and running and what speeds they are reaching. Many of us that manually overclock disable all those features so we can fully control the output of the CPU.
