Hello asdds22!, If I have not misunderstood you disable the Intel turbo mode, the C-state and then set the CPU multiplier to 46 ...it seems that you want apply an OC in fixed mode, is that correct ?!

Hello Splave, here it is: https://www.mediafire.com/file/loa5mpu5nqmfn2h/Splave_Z17MOCF7.51G.zip/file and these are the mods: I've taken your previously modded BIOS (that we know is perfectly working) and: - i've updated the OROMs to the latest versions, in particular the RAID OROMs are working and are tested by my-self (https://www.win-raid.com/t19f13-Intel-EFI-quot-RaidDriver-quot-BIOS-Modules-52.html#msg97820), - added the R0 CPU Micro-code, - the BIOS contains the CPU micro-codes which according to specialized forums (whose results for the 8xxx series have been personally tested and for the 9xxx series have been confirmed by friends) are the best for overclocking (on average on different motherboards and with different CPUs), in particular for the performance and the VCore applied in relation to the frequency managed, compared to the previous and subsequent CPU micro-codes. Cheers, KK P.S.: you are a legend in my book... ? SoniX (the U.B.U. developer) and Fernando (the chief administrator of Win-RAID) are also legends that i personally thank for the immense work they do for the HW freak community.

Hello Splave, as you quoted the post where is linked a modded BIOS for the ATX version of Z170 OC Formula, i modded the Zizu32 7.60 BIOS adding an old CPU Micro-code (Rev. "BC") so the R0 would not suffer of performance loss introduced with the latest "CA" revision: http://www.mediafire.com/file/gebuv5etxjanlna/ASRock_Z170_OC_Formula_BIOS_7.60_Modded_%28Old_CPU_MC%29.zip/file Cheers, KK

Hello Synth Wave, this BIOS is the one prepared by Zizu32 and i've updated it using U.B.U with latest CPU micro-code and OROMs. As Zizu32 said it has "tested last weekend and everything works just perfect with 8C/16T" so you can flash it and enjoy your 9900K. RAID OROMs are the latest released, are working and has been tested by me ( https://www.win-raid.com/t19f13-Intel-EFI-quot-RaidDriver-quot-BIOS-Modules-52.html#msg97820 ). Cheers, KK

BIOS is 9900KS ready but for those who want everythings up to date i've modded it with latest OROMs and CPU micro-code and you can find it here: http://www.mediafire.com/file/956bgdnts31k6az/ASRock_Z170_OC_Formula_Modded_BIOS_7-60.zip/file details of mods are indicated here: Cheers, KK

Thanks a lot Zizu32 for sharing it! Oh yes...the good "old" CoffeeTime... ? Is your BIOS patched for correct core selection and DSDT and CPU SSDT to support 16 thread?! Thanks again for your work! ? Cheers, KK

Hello Zizu32, is it the 7.60 that is available on ocxtreme.net?! (http://ocxtreme.net/viewtopic.php?t=23) If you'll send me via PM your modded and perfectly working BIOS i'll host it to my MediaFire home. Cheers, KK

Sorry to hear that… A friend of mine have successfully used it without issues on a i7 8700K @ 5.0Ghz AC with G.Skill RAM @ 3.600 Mhz. What revision of Core i9 9900K do you have, P0 or R0 ?! Cheers, KK

The modded BIOS that i posted i think is working correctly because to date there are 52 people that have downloaded it and no one has sent me private messages to tell that something was wrong … Cheers, KK

Hello Synth Wave, i've updated with U.B.U. (UEFI BIOS Updater) a previously modded BIOS by Lost_N_BIOS of WinRAID that i personally thanks: https://www.win-raid.com/t4089f16-Enabling-Secure-Erase-in-Z-OC-Formula-3.html#msg87280 The update includes: https://postimg.cc/2bzH205S BIOS download: http://www.mediafire.com/file/j0d7i289xjv78cg/Z17OCF7.40B_Modded.zip/file Cheers, KK

@Splave Hello Splave! Any news from Nick about new BIOS for ATX version of Z170 OCF?! Thanks for your time and patience. Cheers, KK

@Splave Thanks a lot m8! Any news for ATX ASRock Z170 OC Formula?! Have a nice day.

Thanks for your feedback RULE! I didn't try with BIOS supplied by NickShih (http://picx.xfastest.com/nickshih/asrock/Z17OCF7.51A_CFL.rar) because I had the doubt it was necessary to update the CPU Micro-code to correctly recognize and manage the Core i7 8086K. Cheers, KK

@NickShih Thanks a lot for your efforts Splave! Nick would you be so kind to give us some infos about the hypothetical release of modded BIOS for ASRock Z170 OC Formula that have full support of Core i7-8086K?! Thanks to both and have a nice day. Cheers, KK

Hello flautze! I've checked this Rev. 7.51A/D BIOS and it's updated with latest CPU micro-code for SkyLake (C2), KabyLake/CoffeLake (84) that Intel released to mitigate Meltdown/Spectre (https://newsroom.intel.com/wp-content/uploads/sites/11/2018/03/microcode-update-guidance.pdf) so you'll be able to use your i7 6700K and/or any KabyLake/CoffeLake and you'll be "protected". As stated by Splave you have to flash BIOS with a SKL/KBL CPU, shut down the MoBo, swap CPU and power-on. Cheers, KK
