OC and Windows 10 1903

Can anyone confirm that the new 1903 version of Windows 10 messes with overclocking again?.

I have a X99 gaming with a i7 6800K and the last version Windows (1803) disabled overclocking in the BIOS, this was fixed with the 1903 BIOS but it took Asus a very long time to release the fixed BIOS.

I have not yet received the the 1903 version of Windows via the updater and want to postpone the update if it messes with overclocking again.

Good afternoon,

The latest version of Windows 10, 1903, seems to pose compatibility problems with previous Intel CPU microcodes, on Z370.
If the microcode replacement was done through a BIOS update, OC capabilities are altered.
If the microcode update is done dynamically through the loading of mcupdate_GenuineIntel.dll during the OS initialization, then there seem to be two cases: if the file provided with the 1903 installation is used, the CPU can no longer be overclocked, whereas if a previous version is used, the OS fails to load, and also cannot identify the cause of the issue, so one has to start the computer in recovery mode, launch the terminal, and delete mcupdate_GenuineIntel.dll.

So far, I had been using a version of mcupdate_GenuineIntel.dll prior to Spectre/Meltdown mitigations, but is seems to ne longer be possible. The only remaining option, to preserve the original performances of the CPU, is to delete the file in order to use the microcode from the BIOS update (using the version prior to the integration of Intel fixes by Asus). I wonder if the structure of the files including the microcodes changes through Windows 10 has been modified, preventing the OS from using previous versions.

Not much movement. Maybe it would help more people raised an official support request for "updated BIOS for the Rampage V Extreme to address the recent intel CPU vulnerabilities."

Updated and running.

OC seems to be working just fine again.

No crashes or bluescreens so far.
