Gigabyte Z97MX gaming 5 Bios reset problem

[Daryl Chetcuti]

Hello people, how you all going today,

My name is Daryl, i have been a PC technician (+MCSA) for a while now and I'm looking for other expert advise/help with my problem.
Just upgraded my rig (tax return gift) and i am having one annoying problem.I Just bought the system last Friday. Brand new motherboard, memory and CPU

My problem is every time i cold boot the PC i get a bios error message saying my

"Bios has been reset - Please decide how you want to continue
Load optimized defaults then boot
Load optimized defaults then reboot
Enter Bios"

So i initially thought the bios battery is dead, checked the voltage of the battery it read .2v (battery DOA). New battery installed, same message. Been like this all week. At night i shutdown windows, i switch off the PC at the wall then the next morning the bios error. My bios setting are not getting saved.

So at the start of my day i setup the bios and it runs perfect even if i do a reboot. The problem is only once i turn off power at the wall, i lose my settings.
The new battery i replaced is still reading 2.8V which means its still good.

Ive tried taking everything out of the system and replacing 1 by 1.
Upgrade the bios to version F4
Replaced battery.

I can only say the cmos battery holder has some cracked soldering joins or a track on the board is cut somewhere. I have contacted gigabyte tech support and im waiting for a reply but I'm open for any suggestions.

My setup is
I7-4790K
H220 WATER COOLER
Gigabyte Z97MX Gaming 5
kingston beast 2x8gb
3 various SSD's
Gigabyte Odin 800w PSU
Gigabyte 280x
Antec 900 case



Regards
Daryl

Hi and welcome to our forum.
Yea,it's unusual that new board came with death battery.
Can you try to clean this cracked soldering joins in battery holder ?
Seems to me is shorted,so like Clear_CMOS..... must start setting all over again.
If new battery is already 2.8V...very soon will be death again.

Yes,contact your shop or GB direct.

Edit:
Can you check with multimer resistance of Clear_CMOS pins?

Hello stasio,

thanks for your quick reply.
I tested the clr_cmos pins and got no readings at all, open circuit which right.

That's good.....
Also you can check in battery holder.
Anyway Clear_CMOS pins for 10-15 sec (with battery in, unplug your power supply), maybe help.

Ok, the battery holder read 1.08ohms at 20k,
i tried removing the power supply and reset still no good.
Any other ideas are greatly appreciated.
Thanks for your time so far.

hey, i created an account here to post just about this. i received the same board z97mx gaming 5 about a week ago and am having THE EXACT same problem. computer works fine as lonmg as its left plugged in, but if i unplug it from the wall or switch off the power on the psu, it forces me to resetup the bios everytime. i also purchased 3 extra cmos batterys but problem still exists. just wondering if the OP is around and how his situation was resolved.
