Disconnect Windows time from the BIOS time

I am one of the many unfortunate owners of an Asus motherboard with a UEFI clock freeze problem. The clock randomly freezes and when it does, apart from the Windows time going wonky, it causes havoc with certain applications that I run that rely on the BIOS clock. This includes Precision Manuals Development Groups (PMDG) Boeing 737 simulator for FSX. The problem is widely reported on the ASUS ROG forums and affects quite a few of their high end boards. Mine is the Hero Maximus VI. They are as confused about the issue as us unhappy owners and have yet to identify a solution other than a total reset of the BIOS which is irritating when you have tweaked settings for over clocking. This is not a BIOS battery issue, it is a software or hardware fault that is causing the BIOS clock to freeze. So no "change your battery" comments please :)

Anyway, in an effort to fault find, is there a way to totally disconnect Windows time from the BIOS clock? As I understand it, when Windows corrects its time using the time servers, it will adjust the BIOS clock also? Maybe this is when the freezes occur and if I can stop this process, maybe the problem will "go away".

Try this software:
Thinking Man Software - Dimension 4 v5.3
I think that you can set it to sync each minute.

Thanks UsernameIssues but that might only add another variable to the fault finding equation. I might try it if all else fails though. My issue is not with how accurate Window time is but how it communicates this to the BIOS.I want Windows to stop "talking" to the BIOS clock.

I figured that you (or others) had looked at (and researched) every option in BIOS for these motherboards... so, the only hope that I saw was to have an app change the Windows time every minute. There is always a little error (due to the way this stuff works) so Windows might tell BIOS of the change every minute. Perhaps that will stop this BIOS lockup by resetting some process that causes the lockup.

Do you have an option to enable/disable HPET in your BIOS? Which ever way it is now, set it to the opposite to see if that helps.

Thanks I will try this and see what happens.

OK, thanks - does make sense. Won't hurt to try this and see if it helps.
