BCLK in and of itself doesn't make something unstable. 127BCLK is perfectly fine. If you have memory that is at a stable strap at that BCLK, then it's no different from a multiplier overclock. 

 

What makes the 5.1 result impressive is the fact that it is on air, an unspecified air cooler at that. Potentially, a custom loop could get that voltage down quite a bit. We already know Skylake is safe at 1.4v if thermals are taken care of, so Kaby should be the same in that regard. 

What I meant it is more complex to get a stable overclock that way than simply change the multiplier and increase voltage to insure stability. Very little people can manage BLCK overclocking. That means it is insignificant to the casual overclocker which is why I would like a realist overclocking scenario for the typical oveclocker rather than what is included in the article.

 

Secondly, BLCK overclocking boosts everythings speed going from RAM to pci slots passing by SATA ports which is not something you would want for day to day use

Mind if I add this to the first post?

This no longer applies to Skylake or Kaby Lake. PCIE is no longer strapped to BCLK. 

 

I do understand your point, but a lot of us older overclockers came from BCLK overclocking. It's all we had back then, and some of us still use it (170BCLK on my Skylake 6600T for example). I am certain the raw CPU overclock would be stable with a simple multiplier overclock. Probably some sort of random integer division error holding them back from doing that now, and a BIOS/Microcode update might be required to use just the multiplier on the Z170 boards they are using. The multiplier itself could also be limited to 50 or something, don't really have the details yet.

Require? No. However, Z270 offers additional features not present on Z170, such as native thunderbolt 3, 4 additional PCIE lanes (24 vs the 20 on Z170) and Optane support just to name a few. 

 

A BIOS update is all that is required in order to support Kaby CPU's on current Z170 boards.

Oh cool, that's awesome. What's Optane?

New storage technology that uses physical DIMM slots for non-volatile storage. Basically an SSD that you can put into a memory slot. I personally question it's use in the desktop world, but for mobile devices that already use soldered ram, a soldered, low-profile storage solution isn't a bad idea for a thinner product in a spatial sense.

That's super cool.
