Thanks for reply. That post was about how silly the task manager of windows 10 is (cause can't recognize real core clock) Thanks to you and your bios, I overclocked 9900k with fixed clock at 4.6ghz with 100mhz blck. No probs and stabled oc. benchmark score went high. And... guess what. having several baffling errors... only when I gaming. When I play game, especially the game made with unreal engine. tons of windows bluescreen error come out (do not means there aren't any issue with other game, almost every game crashes). checked my overclocked memory with memtest86, checked SSD and HDD. ran tons of stress test(prime95, blender benchmark, 3dmark fire strike, time spy) and can't figure out what is the cause (even that, benchmark score tells me that the score is high and valid! ) I've been built my pc from 2014, been met several windows10 bluescreen error and I've been proud with my pc troubleshooting. But this issue makes me confusing. Because when the crash start, whole pc is going down. uefi can't boot in the end ( uefi tells me i have to default my uefi settings.) i have to clear cmos and have to default the uefi and oc again then re-install windows10. 'custom uefi is based on non-ME uefi' would the issue? at this point, my insight with troubleshooting is suspicious. Can you advise me where can I start? Unless i play games, there isn't any issue with general pc usage. Edit: I wrote this for finding helpful debug insight. Because In here, many insightful overclocker is helping others. I think i found the cause which crashed the game, but not at the stress test. stress test program solely stress cpu or gpu. I tried gpu stress and cpu stress simultaneously and psu was shocked for the load and the pc restarted. So, 600w psu(FSP AURUM S 600W AS-600) was not enough for 9900k(4.6oc) and ram oc and 980ti. That's my conclusion and will give a shot with new psu. Can't understand why Firestrike and Timespy can't help me finding this prob. Feel sorry writing off-topic thread. But instead of delete, leave this here for record so that maybe another guy care about his psu when use coffelake cpu with z170 mocf!

appreciate your contribution. Tried your bios on my z170 mocf with 9900k r0 and have interesting issue(not performance issue). When I turned off turbo boost and C-state, and OC the CPU up to 4.6Ghz, HWmonitor recognized it.but task manager didn't. The clock was locked at 3.6ghz in task manager while HWM saying that the CPU is at constant 4.6ghz. Even that, memtest86 also can't detect my CPU oc clock and saying my CPU is at 3.6ghz while i overclocked it. (can check CPU and Memory clock while testing own memory via memtest86) I installed the windows several times so clearly there's something happening on my hardware.Can't figure out the cause.

Seems this bios will work perfectly and you must do isolate and short pins on your cpu

I tried 9900k (R0 stepping) on z170 mocf and the oc was wonderful. you can use your cpu via this bios. I can speak japanese so if you wanna question, you can send me a message
