	Great results! A ~30% performance bump is nothing to sneeze at The fact that it is on a non-K CPU is even more awesome! This reminds me of my days with my old Celeron 300a getting it up to 700mhz and wiping the floor with pentium 3s at 450 - 550mhz. I think I ran it at 600mhz 24/7. An old era has returned and I for one can't wait to see what kind of fun can be had with Sky OC Edited by Xaltar - 29 Dec 2015 at 3:17am

	Yes sir, great job. Sure hope intel just decides to leave this alone. Let people enjoy their hardware.

	Nice, nice, nice! Now if I could only get a decent non-K Skylake processor locally. All I can get are Skylake i3's, or non-K i5's, but the i5's are over $200!! I guess I'll just try the beta UEFI for my Z170 Extreme7+ on my 6600K, and see what happens...

	That would be great to see Parsec, you can try BCLK overclocking vs Multiplier overclocking and see what kind of difference it makes on the same platform

	raising BCLK to overclock is really not something new, I've been doing it on AMD CPU for years and you can do that to old intel processors, if I'm correct you cannot do that on anymore on sandy bridge platform(LGA1155), used to overclock the hell out of a Celeron back in the socket 478 era

	Before Sandy Bridge the BCLK was determined by a chip on the motherboard and it was up to the motherboard manufacturer if the end user would have access to the BCLK settings via BIOS. Even in cases where it wasn't you could use software if you could identify your PLL (clock generator) chip. Sky OC gives us the same control almost a decade later. I used to have a socket 478 Pentium 4 2.4b that I overclocked to 3.6ghz using nothing but BCLK and voltage. Those were the days I want to see return

	Just hit 4.32GHz using the same mobo/cpu combo but I had to up the vcore to 1.39v and set LL calibration to level 2 (only sagging to 3.6v under load now instead of 3.44, which didn't keep things stable when running prime). I also upped the PCH to 1.1 and DRAM to 1.3, but I'm not sure that those last two were necessary. What voltages do you have dialed in yourself?

	Turns out that I couldn't get things completely stable with a 160MHz BLCK after all and I didn't want to up the vcore any further. Dropping down to 159MHz does however seem to be a rock-solid plan :)
