Sabertooth Z87 - Bios Clock Issue

[Krait]

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.

I know this isn't the correct forum section to post in but the topic is relevant. I have the exact same problem with a Maximus 6 Extreme, bios version 711. Everything seems to work OK but the clock in the BIOS is frozen at whatever time windows set it to when closing down the PC. I first notice the problem when waking up from sleep and find out that the time froze at what ever time I put the PC to sleep. Time starts moving again in windows as you wake the PC but the clock will only carry on from where it left off when put to sleep. Clearing the BIOS and reloading my profile starts the clock moving again in the BIOS but it only lasts for a few days then does it again. I've not figured out what triggers it yet, but it certainly isn't a flat battery, I tried changing it.

Re-flash the latest UEFI, and clear CMOS with the board in standby (this will reset the management engine). See if that helps.

Did you reflash the UEFI and then clear the CMOS with standby power applied as Raja wrote above?

Ok I will try that and report back here if succesful. I understand that "with standby power applied" means that I should clear the CMOS with the jumper on the motherboard without turning off the PSU from the mechanical switch. Is that correct?

Yes. Power supply on but the system off.

You're welcome. 🙂

OP please confirm that the fix provided by Raja resolved your issue 🙂

The problem seems to have gone now. 🙂

I re-downloaded the bios, but I used the second mirror (the date of the bios was 2 days later, if I remember correctly) - not sure if that made any difference. I then cleared cmos as usual and flashed the bios with the flashback facility.
It's now been working perfectly for about 3 weeks.

Just adding that my newly installed motherboard, Z87 Sabertooth, is having the clock issue. Did all the recommended stuff but the clock is still ffrozen. Is there a fix in the works? Clearly this is a serious problem with the z87 Sabertooth from Asus.

Asus Z87 MOBO Frozen Bios Clock Issue
Can someone please inform me is this an issue that occurs only when any kind of overclocking is done.
This includes enabling XMP profiles of RAM that has XMP feature.
In other words is there anybody out there who has had frozen clock issue where no overclocking was done.
Thanks...GAry
