BIOS resets once power is lost to the system

Okay I have an issue were my Bios resets ever time my computer is completely turned off and then turned back on.
No it's not the CMOS battery I have replaced that.
Yes I have updated my Bios to F6 latest non beta version of Gigabyte b350 gaming 3 BIOS
Yes my computer is working fine, but I want to overclock so I need to save BIOS setting. Update I am getting random 2 second freezes, that once un froze will do this sort of fast forward thing.
Yes the CMOS battery is secure in the slot.
Also there is no CMOS jumper on the CMOS_RESET pins

Hello... Good Job on not giving up and trying/testing things... B ) You can run RAM without the XMP setting, This is a OC setting and typically will change the communications to 2T timings... if your MB and RAM BOOT up without XMP and at 1T, save&exit... that is a FAST RAM communications too, leave it there and go about with other building/installing activities.

You must not have read my entire post
 
Hello... sorry... well did you check the voltage of the "replacement battery"? 3.3volts

Basically... remove the battery and do a CMOS 'jumper" clear ~2 mins... remove "jumper" clear... replace battery... and on the next Boot, New CMOS information will get gathered from the "installed' hardware and re-stored in your CMOS Chip... do another re-boot to see if you still have this error or if it was cleared B )

Basically if you are trying to OC the memory and you put in "BAD" un-bootable numbers... the MB by default will resort to the last 'Good' know setting... so it seems your OC numbers are bad or your Ram will not run at them... Ram is very fast at what it does. already... try increasing the voltage to them or relaxing the timings on them to get your 'desired speed" B )

To do a CMOS clear do I just take the battery out for two minutes? I don't need to jumper anything do I?
Also yes the new CMOS battery is the same model number as the orignal C2023 which is 3V.
Thanks :)
 
Hello... 1) the battery is the power to the CMOS chip... doesn't come from any where else... but a backup capacitor.
2) if you jumper with the battery in the MB you will drain the battery... (don't do this)
3) there is capacitor on the MB to allow time for a battery replacement... (like most battery backup household devices)
4) the ~2min Jumper time will drain the backup capacitor on the MB... at this point the CMOS chip has no power to it and no "1's" in it... (totally clue less.)

5) re move jumper (or push button)
6) insert "good" battery
7) On next Boot the Bio's will see there is no bootable information in the CMOs chip... and will start to gather hardware information on your MB... one of these is a 'Good' bootable setting for your RAM to be used and have communication with the memory controller.

and that how it works... B D any questions?

So basically every time you give it BAD OC data and it won't Boot... you need to remove the battery and do a jumper to dis-charge the capacitor backup... and you will be back to The BIO's version 'default' settings... pretty easy fix for 'OC'ing trial and error'

Okay so I remove battery, put the jumper on and wait for two mins correct?
Well sadly I don't have a jumper :/
Edit: I think I understand, but to be sure Ill remove the CMOS batter for 5mins just encase the capacitor is larger
 
Hello... Some Newer MB's have a "push button" now... 1) battery removal first... 2) then clear the voltage on the "back-up" MB capacitor... 3) replace battery and 4) re-boot to the BIO's defaults and the newly created CMOS information with BIO's determined "good" RAM settings.

I think the "push buttons" are a good idea now... makes it's easier for the user to use and they can't get confused when re-moving the 'jumper" later, or losing it in between use B /

If you have a Intel CPU with 'integrated" IGT/GPU... the default BIO's program will enable it for use... what this means is... you need to remove any "exterior" Video card and plug your monitor into the MB video connectors to get a Display... then you must change the BIO's setting back to "EXT PCIE" (save&exit) and power down... and insert your Video card and monitor connection to it for the next Boot.

If you are just 'experimenting" with OC settings for the RAM and/or intel CPU... save some time and procedure steps, and do this without the Video card installed... it can be added later after you have found and saved the NEW 'Good" OC settings. B /

Okay, I removed the cmos battery for 10mins and then re inserted and the problem is still occuring
 
Hello.. OK... that good info... so you have not properly cleared the CMOS yet, due to jumper missing, to safely do it B )

1) Ok... well look on one of your HD's ... and borrow one from it? B / do you have a HD with a jumper on it? that should work/fit

2)or in the Mb BOX for the MB jumper then? ... in a plastic bag there?

Okay, So I cleared the CMOS by using a screwdriver and powering the system up, it cleared the CMOS I assume because of the time reset (although my bios is still updated I think that's normal though)
Anyway nothing changed and I'm still getting the same problem. Do you think it is a faulty motherboard?

 
Hello... The CMOS clear does not remove your BIO's version... it only clears any changes to it... and starts a NEW hardware, memory, and communication search of all the current installed hardware in the MB... also your settings in the BIO's are back to "Default" settings per BIO's version.

Yes then I have reset it, and nothing has changed, but if you look at this picture again : https://drive.google.com/file/d/0BxO0GucSCZHcUmM1YnR0ZUJuWGc/view?usp=sharing
it resets the CMOS every start up(start up meaning completely turned off and on from power outlet) anyway, wouldn't that mean there is no point in reseting?
Thanks for you help btw.

It's as if the motherboard is having the same symptoms as if there wasn't a CMOS battery in my computer, or the clr_cmos jumper is still on the pins.
So I guess the question is why is it resetting the CMOS on "start up".
 
Hello... 1) I have had to RMA MB's because of 'Bad" BIOS/CMOS chips.. it is not un-common at all in the business. Solution? ...Typically If you give them a call with the serial # they will be aware of a problem with this from other owners like yourself with this same problem. Don't Blame anyone or yourself... it is the nature of the business, a inconvenience, there are alot of steps to make a MB... they are dependent on alot of other peoples parts for them along the way.

2) Your CMOs battery could be bad... they buy them by the crate/pallet full and they can sometimes sit on a rack in extreme storage conditions. Solution? ... buy a new one at different store and try it or take a multi-meter/battery tester and test your existing one... This is still a "cheaper" solution than paying one way shipping for a MB... automobile battery's makers have the same problem from time to time.

3) Try a OLDER/Newer/Same BIO's version re-flash... maybe that can fix the One's and zeros in it... B /

4) After that then the fix and problem lies with a RMA... basically they will ask you to remove the MB from the case and Test/boot on the MB BOX with minimum hardware plugged into it, to insure your Case mounting, installed hardware is not causing it... B /

***if you RMA it you might have to pay one way shipping... Make SURE you've done good testing and question asking on your side... record/img the MB serial # so you know what they send you back B )

Thanks for your help. I might de assemble and do some troubleshooting myself sometime. As for the battery I tested it with a voltmeter and it is working.
If all else fails I'll take it to the place where I bought it.

Thanks for your help, if I find a solution I'll post back here.

I FIXED IT.
Okay so all I did was move my two ram modules too slots 2 and 4 instead of 1 and 3.
Then I got this other error: http://forum.gigabyte.us/thread/952/aorus-ax370-gaming-update-denied
Which is fixed by turning XMP off.
So far it hasn't reset, I"ll update you if I get any further problems

 
Hello... Good Job on not giving up and trying/testing things...

Thanks for all the help! Ye I can just do a custom OC.
Good day to you good Sir.
