Non-k cpu's have an interesting history of mild overclocking
I remember these steps: 1. Turbo mode hack on sandy bridge to allow 4 extra bin (i.e a max turbo value of 3.6GHz with one core active would become 4.0GHz, 2 cores active at 3.9GHz insted of 3.5GHz etc.) 2. The above was disabled on Haswell but a new functionality called Multicore enhancement could lock all the 4 cores at max turbo value 3. SkyOc on skylake which allowed unlimited BCLK overclocking but disabled speedstep, turbo, c1 states and core temp reporting What will be next? |

The sad fact is that Sky OC was a gamble as to whether intel would allow it. It was a gamble that lost. No matter what intel's official response may be (nothing as yet), it is quite clear they were behind the abolition of the feature. Users have to understand that Sky OC was essentially a hardware and firmware level hack to implement a feature not officially supported by intel. In any scenario where the term "hack" can be applied it must always be assumed that the functionality will not be perfect.
Sky OC allows for a quick and dirty OC on Z170 boards when paired with a non-K CPU, much like the implementation of non-Z overclocking on previous generation Haswell boards. With B/H series Haswell boards the user had to be willing to accept the fact that the OCing utility was very limited in so far as the number of tweaks that were available, no LLC, no RAM overclocking, no BCLK settings as well as fixed voltage even if you selected "adaptive". This is now and will always be the case when a manufacturer provides and unsupported feature. Does that mean the feature is bad or should not have been included? Obviously not, there are always those to whom the weaknesses of said features will be offset by the benefits. ASRock consistently pushes the boundaries with it's products, especially where it comes to adding extra value for it's users. Not all of these features will take off and not all will remain in play but the fact that they keep trying and are willing to risk the ire of chipset and CPU providers is truly a testament to their commitment to us as end users. It is sad that Sky OC is being phased out but for those who already have capable boards with the few BIOS versions that support it, you still get to use it

First, Sky OC is officially dead, if you haven't noticed all the UEFI updates flooding in for Z170 boards.
For example, the description for UEFI 2.60 for my Z170 board: 1.Update microcode to 0x76. 2.Remove Sky OC function. This is a news item at PC enthusiast websites, so you can find stories about it all over the Internet. If you like Sky OC, don't drink the poison UEFI update. ![]() Given this development, there of course will NOT be any fixes for bugs related to Sky OC. ![]() But doesn't anyone remember the limitations that were part of Sky OC? There used to be a list of them posted on ASRock's website, which is probably gone now for obvious reasons. Regarding the VID and offset voltage UEFI setting, that behavior may be normal for a non-K processor. That is, the ability to override the VID with an offset. For a non-K processor at stock clock, what is the use of that? Sky OC worked, but it was far from perfect. All the limitations that did NOT exist in the golden days of over clocking (before Sandy Bridge) that have been added since then were not washed away by Sky OC. Sky OC tried to use a difference in Skylake processors that exists for the first time since Sandy Bridge. That is, the CPU BCLK is not shared with the PCIe lanes, DMI3 lanes, etc. So the CPU BCLK can be changed without affecting (and crashing) the other things that depend on a stable clock value. To bad it is not that simple. Other changes along the way since Sandy Bridge, and some new to Skylake, have weird side affects when the CPU BCLK is changed. Like the integrated graphics no longer working, C States no longer functional, and... was it no CPU temperature or no VCore reading, I think the former. For me personally, some of those shortcomings made Sky OC much less attractive. Another thing, VID and VCore are not the same thing. With Adaptive voltage, the actual VCore can be lower and higher than the VID. Actually, I want someone to tell me what voltage option(s) are available besides Manual, with Skylake processors. For example, what is the Auto setting equivalent to? Is Adaptive still an option with Skylake? We think we know these things, but do we? ![]() |

I just spent a few hours figuring out that I could only increase voltage offset effectively if I leave BCLK at 100.

I still hope ASRock will fix that with the next Bios even if this is a low budget board

I am having exactly the same problem with my Z170M Pro4S, on both L2.23 and L2.40, firstly there is no voltage control, only voltage offset options, secondly, if I change my BCLK to anything, the voltage will always be stick at auto (1.088v). Should I refund this board and go for a Gigabyte or Asus which have similar price?

at least on the Z170M Pro4S, SKYOC does not work really good with the beta bios, nor the 2.40.
you can set a vid offset to a non k cpu which will only work if you leave bclk @ auto. when you increase bclk you are able to set any voltage you want but it will not affect the vid, so you are very limited to the oc by the default vid..Yes, you can leave offset @auto -> 1.05v, or +400 -> 1.05v. i already mailed to the support weeks ago but no answer. |
