Problem with Bios......intermttent loss of saved settings.

python134r · 10 Apr 2012

As of late I am experiencing a strange loss of Bios setting when I either warm boot or cold boot.
Examples as follows:
When restarting either from a warm restart or cold restart, I will hear 3 beeps which I believe is a memory related error, correct me if I am wrong. I do know if settings go back to default range the voltage is less than what is needed to successfully boot with OC settings enabled.

I have also noticed that I sometimes do loose all of the bios settings under many different conditions, regardless of how and why I had to restart.

The one setting that stands out the most is the FSB setting, many times this value is the only value changed; [goes back to default] and needs to be reset.

This machine has given me yeoman service since 2008 and has been OC'D at a 50% overclock 60% of the time, the rest of the time it is OC'D at a bit higher rate and stable.

I did replace the Battery on the MOBO[P5K-Premium WiFi/AP thinking this might possibly be the cause. I have found the incident of this happening to be less but values in the BIOS still change however infrequently.

I was thinking that the Bios could possibly be corrupt and might reflash it. I would appreciate any thoughts anyone has on this issue.

I have had so very little issues with this build I have taken it for granted, it still is very quick, it still works great, I am in the works of getting together a new build but this issue is annoying.

Again, any insight would be appreciated, ThanX...........

I reseated all hardware, replaced battery, however the frequency of this happening is much less but still there, I am installing a Boot SSD or the OS later this week, a clean fresh install, I remain optimistic.

No-one has ever heard of this issue, when a bios defaults back to default settings upon an error?

Yes the OP said he has, but it must be recognised that this is symptomatic of either a failing battery, whose to say the new one is as good as it should be ?, also it can be the sign of a nobbled CMOS chip. I would certainly try either a new battery or look to the manufacturers web site, there may be a BIOS update that helps this problem.
I checked, theres an awful lot of updates for that BIOS, whilst it doesn't mention your particular problem I do feel it is lacking stability and would personally use Asus EZ flash to update, just to see. (I don't recommend updating the BIOS code lightly !)

Here's a link.
