Sabertooth Z87 - Bios Clock Issue

Krait
Level 7
The basic problem is that the clock in the UEFI bios stops working on a regular basis.

I can remove the battery and it will restart (at least for a day or two) but it always stops again - I've tried 4 different batteries and the longest that the clock continued to work was 8 days.
It's only the clock that doesn't work (at least as far as I know) - all the other bios settings stay the same (except when resetting cmos ofc)
I've tried it at stock and OC'ed and it still persists in stopping, I've also tried using my older PSU (Seasonic 860 xp1) and the same result.

I suppose it's either a bios problem (bios 1205) or a MB fault but if anyone has a suggestion for me to try, in case it's neither of these, it would be most welcome.

Hey guys.

I am the owner of a Maximus VII ranger and I'm affected by a frozen bios clock... It messes up my windows time...

Can you pinpoint me to a solution for this ? It seems that the problem appeared when I installed the MEi for the ai suite III

Thanks a lot

Just chiming in again to confirm that the issue still does seem to be resolved for us. Windows Time Sync (Internet time) thing occasionally resyncs the Windows clock to the wrong value, we've since changed what server it syncs against so hopefully that's resolved.

There is definitely the possibility that it ISN'T resolved and the clock is being resynced using the internet each time we turn his PC on, masking the issue. I haven't really bothered to test this out, but I easily can. I actually might test it out now that I think about it. I'll disconnect his PC from the internet, leave it off for an hour or 2 and turn it on, see what the clock says.

I've tested the computer without it being connected to the internet for several hours while turned off, and still disconnected from the internet when it was eventually turned on. The clock and date in the BIOS remains correct.
