@jacky400 - Please put those images in a zip, thanks. YOu can screenshot to USB via F12 hotkey, will make smaller and more exact BIOS images - FYI
I'd still want them in a zip though, thanks

@Lost_N_BIOS . Here it is screenshot zip that taken using F12 in BIOS with the CPU configration page .

@jacky400 - please enable "SpeedStep" and then show me new image of bottom of CPU config page, thanks

@Lost_N_BIOS here it is

@jacky400 - Please flash this via FPTw.exe -bios -f seto2m.bin
Then show me new image of CPU config top to bottom (well, you can skip the greyed out stuff up top )

@Lost_N_BIOS Many thx.There are more options shown under CPU configration page now. Tried to change the 1-core/2-core/3-core/4-core limit ratio override to 44 .

However it still cannot lock it at 44x mutilpler ....... Not too sure if you have any expereience that may need to adjust more options to get overclock workings

@jacky400 - Please put images in zip, thanks
What multiplier do you get when you set 44? Did you test with "Overclocking lock" enabled/disabled?
Did you set x44 at Overclock >> Core Max OC Ratio

You should be able to at least set the max turbo multi for the CPU (42 or 40), can you run 4Ghz without issue?
Your CPU can only run, bu default 42 on one core, so using the settings you mention if limited to 42, you can only set 42, 41, 40, 40 etc (all things after first 42, must be less)

I found this article
https://www.tomshardware.com/news/overcl...sets,30962.html

Seems like this is known thing, you need Z chipset for CPU multi OC

@Lost_N_BIOS Even set multipler 44 (or 42 for all core), it still run as 40 in windows . Probably nothing can do because of the H170 chipset limitation .

Last resort would be upgrade to 7700k which runs at 44 multipler for all cores . Is it possible to add microcode for it ? (I remember no pin connect/isolate is required if use Kale Labe CPU on Skylake motherboard , correct me if i'm wrong )

As mentioned, 40 or 42 may be max you can set, turbo would need to be enabled and C3E needs to be enabled too.
Please put images in zip, so I can check and see if anything missing I meant to be visible to you.
I have never had any luck updating a BIOS from Sky >> Kaby, but we can try if you want. Microcode and vBIOS/GOP need edited, and possibly ME FW too, not sure.
Ideally you would only do this with programmer in hand, especially if we need to mess with ME FW

@chinobino - can you confirm what all is needed to do Kaby on Sky board? Thanks

Better option in my opinion for you to do is to purchase another mATX "Z170/Z270" board to put in there instead, one that is compatible with CPU you have, then you can overclock to whatever you want.
I assume it's mATX board, but check first of course

@Lost_N_BIOS Let me set 42 for 1-core/2-core/3-core/4-core ration limit override and Core Max OC Ratio . What is the turbo option you mean ? and i don't have the C3E option under CPU C-state yet.

(if i can get 42 multipler work , it should be enough for me and I can forget about upgrade to 7700k :)

Here is the zip

@jacky400 - You can set whatever at those turbo options, but how I mentioned to do it is the only way it works/gets applied
You should see similar help info when you hover or select each one, it will tell you the 2core option must be equal or less to the 1 core option, 3rd core option must be = or less than 2nd core option, and so on.
But, the way your CPU works is single core under load only gets 42, all other cores can only do 40, I think.
Unless @chinobino - can some kind of all core turbo be applied here? I made visible Overclocking Lock (ie MSR 0x194), default disabled. Should that be enabled?

Turbo would be the main Turbo option >> Turbo mode. Show me what all you see under C-States when you have C-State enabled, or is nothing there?
Ohh, I see in images now, thanks. There is no individual C-State control here, so you will have to test with it enabled/disabled and see which works best for you.
I can see in your images, there is some things I meant to be visible to you still missing, so follow up BIOS edit will be coming your way tonight

@chinobino - Ohh yes, I remember that now! I have those BIOS, at least I think, and some had some issues on some systems too. So yes, not ideal!
Thanks!

@jacky400 - Here, please let me know if you now see the stuff you circled in AMIBCP under C States, and if you now see AES setting too - thanks
I think 4Ghz is your max option here, sorry If you want higher with that CPU, you'll have to get a Z170/Z270 ITX or mATX board, or full size board if it will fit in there.

@Lost_N_BIOS yep i can see all those C states along with AES .

Many thanks for your help in this long mod bios journey .

@jacky400 - Thanks, and sorry we couldn't get you 4.2 4Ghz should be plenty though, if not, check out some used Z170/Z270 that will fit in your case
And, be sure to get normal mainstream board, not OEM etc.
