X670E Aorus Master bios battery draining very quickly

[gijoe50000]

So I recently got an X670E Aorus Master and the bios battery was DOA, not holding clock or bios settings; and spending 15 minutes waiting for memory training every day is a nightmare, so I have EXPO disabled.

In HWinfo the bios battery is reading as 0.840V.

Ordinarily I would just swap out the battery, but in this case it looks like a full strip down of my watercooling loop is needed...
And I will also have to remove the motherboard from the case...
And remove the backplate from the motherboard...
So that I can remove the screws for the chipset heatsink...
To remove the heatsink...
Just to remove the CMOS battery.

Now I have no problem doing this, once, maybe twice if I still have this board in 5 year's time, but what I'm worried about is that there's a lot of talk online that the CMOS batteries just don't last very long in these motherboards. And I don't want to have to come back in 3 weeks to replace the battery again, because I'll only have just recovered from the trauma of doing it the last time.

So I'm wondering if anybody has any information on this, like is there something else on the motherboard drawing power from the CMOS battery?
Was it just a bad batch of CMOS batteries?
Or maybe some of the earlier bios versions were doing something funky with these boards?
Or perhaps some setting in the bios that I can turn off?

Anybody have anymore info on this?

All the battery does is hold the setting in the cmos. Once you replace the battery and it does it again I would contact support. Why would they do this in the first place. By putting a battery under a heat-sink???

I know right! It seems like an incredibly stupid decision, especially considering that they must have done something to the bios to make the battery drain this quickly, maybe connected the bios to the RGB on the board, or the way it connects to the desktop or something..

Greetings,
Will be curious to hear what you decided and if replacing the battery worked.  I've seen this type of design in other products as well.  Cameras specifically.  Some have a replaceable battery, others require a teardown that you as an end user don't want to do.  All for a .25 cent CR2025 battery.

Yea, I replaced the battery about 2 weeks ago, and it was a hell of a job! I spent pretty much the whole day draining and disassembling my watercooling loop, removing the motherboard, then the backplate and then the chipset heatsink.

The new battery initially read as 3.0v, but it dropped to 2.8v within a few days, and now it's down to 2.6v (according to HWinfo), so I can't see it lasting too much longer.

I don't think I'm ever going to do that job again... if the motherboard comes out then it won't be going back in unless I RMA it and know for sure that the problem is sorted. No way I'm doing a complete teardown once a month for the foreseeable future!

Really idiotic decision by Gigabyte to put the battery in such a difficult place, without being absolutely _positive_ that the battery will have a long life..

Agree.  This is a bad design for a motherboard.  Hope it works out for you.

Yea, it doesn't seem to be though.. just turned on the PC today at 15:30 and the time was wrong, it was reading 01:30, and I knew straight away that the battery was drained!
Checked HWinfo and the bios battery is reading 0.888V.. 

Suppose it's time to open a support ticket..

I don't know if this could cause a problem like this. But are all the front panel plugs on right. Most all mother boards are basically the on the pin laid out. The lettering on all the plugs should point down. Plus make sure the Plus & Minus are right.
