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.

Look at the version number - that will tell you which build it supersedes.

What I was getting at is I hope the fix is not applied only to a beta revision of the BIOS, but at least/also to the most recent stable revision.

Is the Sabertooth motherboard recieving a BIOS update to this issue? The v2004 BIOS update listed on the ASUS website that was released in June only mentions:

SABERTOOTH Z87 BIOS 2004 and BIOS updater
Improve System performance

*Note: Must apply the attached BIOS updater tool first before using the new Intel 4th Gen Core processors.

Note: I am specifically asking about the first version of the motherboard, not the MKI or MKII.

I applied the update to my Sabertooth Z87 several weeks ago. Knock on wood, but up to this point I've not had any issue with the clock.

Hello!

I really don't know where else to turn since I have a month old asus z97-A motherboard with the clock issue. New boards, so there doesn't seem to be much written about them so far.

From what I gathered there's no need for opening the case and reseting the clock etc? Just flash bios and voila? Is it possible that the latest bios could fix the same issue for my z97-A?

edit: Forgot to ask if "standby cmos reset" is still needed after flashing? And isn't this dangerous for me/frying the board, since I'd be touching the cap/pins while there is some current stil flowing in the motherboard? Do I need to ground myself or at least connect the antistatic bracelet to the case? Also while the pc is turned off but still plugged in I see no red light, only the green "pwr_led" one. Is that the same one as the red in z87 boards?

Sorry for all the questions, I just don't want to accidentally bust the board.

Thanks in advance!

edit: Flashed bios to version 1205 and clock started ticking without performing the standby cmos reset. Of course this is on default settings. Will try with xmp and ram on 1600.

I think that for this issue to be fully fixed ASUS also must have to fix the defective AMDA00-driver.

That driver is involved in issues regarding fastboot, and as clock-issues often happens at boot and shutdown time I think it is involved in the clock issue as well.

[Wickman]

I don't actually belive this bios uppdate will totally fix the clock thing, I think it's more to it.

As most of the clock freezing occurs at boot and shutdown sessions, I think the deffective AMDA00 driver will also have to be fixed for the problem to totally disappear.
That driver is responsible for most of the problems related to hibernation/faststartup so it would most probably also affect the clock freezing.

Whenever the builds are ready is "to follow". I don't give estimates.

The above information does correct the clock issue. Its been 12hrs, I'm putting the board through it paces. It seems to be fixed **YEA

I have gone six weeks w/o the problem surfacing .... also had it happen 3 times in a day. Until Asus officially says "We fixed it", I don't think we can say we're OK.

And thanks again Raja for sticking with us on this issue. I called Asus TS this morning and they say they are "unaware" of the issue. And while I appreciate the offer to RMA the board, I think it would better serve Asus and its customers if everyone wasn't wasting their time and money sending boards back and forth for a fix that's supposed "in the works" to come via BIOS update.
