I'm having trouble getting BIOS overclock settings to stick in Windows 10--there I'm limited to all-core turbo frequency of 4.3GHz. I do seem to be able to get higher single core boosts though. Are there any BIOS workarounds? Or do I have to use Intel XTU for the overclock to persist in Windows? Running on an Asrock Z170 gaming itx/ac, 9600K, Win10x64 1809.

Edit: After searching back through this thread, I think it may be an issue with CpuMpPei not being patched. Would that make sense with my OC issues?

Edit2: I got all core sync working with CoffeeTime, thanks!

@chaehwasu If you need it. Make dump of origin bios for data restore possibility, at the least.

@Lost_N_BIOS actually we use same method from s.napi.
@Bluesmoke better use 370 itx bios region.

@revlaay - so both CPUmpPEI modules get edited when needed?

Hi, i have asus z170 maximus hero. I wonder is anyone here tried and worked with coffee lake cpu s with this board? I did search a bit but could not find anything and afraid of doing the mod.

@airjordantr - you can use AIO tool, so mod not so worrisome for you
[TOOL] Easy automated Mod tool for Coffee Lake bios

What is your exact CPU? See this, and read posts down the page too

@Lost_N_BIOS yes

i have 8700k and planning to buy 9900k but not a close time. So 8700k is my main cpu. Do i have to do pencil mod to cpu? I just red some problems about asus board , i also red the guides but just want to be sure to hear that someone use this board and %100 functional.

@Lost_N_BIOS

Hello everyone. I am using Z270 supercarrier motherboard. I tried to make a bios to run cpu i7 8700k but failed.
i have flash bios successfully. But when I press the power button the motherboard lights up about 1 millisecond and then turns off.
Bios version 2.10
Intel ME v11.6.0.1026
Below is the image

I suggest you didn't make pinwork.
2 near must be shorted, 2 separate - isolated.

Describe board behavior at power on.
What flashing method you use?

Correct if i wrong.
I geuss, that you used bios shared by NickShin for your OCF. This version contains internal changes not similar with known CFL mod, so can be easily flashed with Instant Flash.
Common CFL mod from community requires reflash ME region, blocked by ASRock. So you need use SPI programmer for it.
