Clock still wrong after new cmos battery

[ryanbatc 12,859]

I posted about this maybe a year ago - and changed my CMOS battery.  Periodically (actually quite often) my Windows 10 clock is wrong.... typically behind indicating a bad battery.  But I already changed it out.

Is there a Windows 10 bug out there for clock sync issues?

Do you have ASUS motherboard? I used to have this all the time but i raised cpu voltage a bit and it has being gone for ages.

So i suspect a slightly unstable overclock

Ok that's probably likely...  It's second hand board Z97 pro ac

Have you tried using a different time server?

My FSX PC back in 2005 I ran windows XP for about 6 years before the battery was replaced, my present one is 3 years old an ASUS Formula still the same battery.

Odd that you have to keep replacing the battery.  If power is off to the computer, is it still plugged into a power source?

I had the same issue with the ASUS Z87 motherboard. Would never keep time unless I used a program that would sync the time with the internet on every start up.  You can read more about the ASUS motherboard time issues here:

Z87 here as well and same issue. Its a known problem and it makes PMDG birds unstable. 

I used to change the battery every 2 month but like i wrote i havent needed to for atleast a year.

Install a NTP client.  here's one:  http://www.satsignal.eu/ntp/setup.html

Modern windows versions should be able to sync to NTP out of the box with no additional software required.

OK, so why is his machine loosing time?  Or better yet, why doesn't his machine sync automatically?

[ryanbatc 12,859]

I'm not sure as I've checked all the automatic Windows 10 sync stuff and its connected to the internet 24/7.  I did bump the vcore to 1.3v.  It was set to AUTO and it went up to 1.296v.  So while having it at 1.3v all the time probably isn't the best, so far the clock is sticking.  I can always change it back.

I don't recall if the automatic NTP sync is on by default. It's under date and time settings in Settings for Windows 10.

Just checked and the builtin NTP function on my Windows 10 machine seems to be on by default.  Some HAM radio operators who use some automatic digital protocols like FT8 have found that the default NTP functions of Windows 10 are not accurate enough for that protocol which is very time sensitive.  They recommend the NTP client I mentioned above which I run.
