BIOS resetting to default cpu speeds! why?

[sram]

Well, this started happening lately, and I don't have a clue why. I just go check cpuz and discover that my stable overclock is gone and everything is back to default!! I go to BIOS and change it back to how it was, and then after a while I just discover it is gone again. I don't know how often it does this because I just discover this by coincidence when I need to run cpuz.

There is no reason for my mobo to reset itself back to normal, so why? System is okay!

What would you say? Sys in sig

It's possible your battery is kaput. You may need to replace it.

Think again.

My Gigabyte DS3L will do it anytime I set a bad overclock. IE, FSB too high, not enough volts, bad RAM timing, etc.. Just tweaking that stuff back to a suitable range fixes the problem. I could always tell when the board would reset itself because on POST the machine would shut down and start back up twice without a beep.

Well, if my mobo should do it because of a bad overclock, it will just do it right away, right? not after two weeks of running normally!

And it is not like i'm not able to run prime for some period of time with my overclock, so why?

I had a DS3 board last year that lost overclock 3 or 4 times during the year. Don't know
what caused it. Must be a gigabyte thing like their cold boot issues.

What appears to be stable may not be fully stable, never discount the possibilty that the overclock could be causing some issues. That said, you could try sending in the mobo for repairs.

Did you reboot at any time in those 2 weeks?
If so, thats the time your clocks will be reset to default.
My X38 only ever does it when I use a setting that is unstable. It tries to run it and fails, switches itself off, powers up and does a bit more homework then reboots for a final time with default settings.

The different part as you pointed out, is that you are able to use your overclock settings for a while but later realise they are back to default again.
You need to find how soon they revert back to default and we should be able to troubleshoot from there.

do you have the latest and greatest bios? Try updating and see what happens, lots of times you cant get a stable oc without a bios update.

Even if there's nothing wrong with the system, on some boards the CPU clock is reset
to the lowest possible speed (way below default in my case) if you press reset during POST.

I had this same problem on a Gigabyte 965 board. The overclock was stable as could be, but the BIOS just kept "forgetting." I think Gigabyte boards are just rotten when it comes to BIOS.

Give us your OCing MIT settings and a link to your exact memory sticks in use and perhaps I can venture a guess.

Offhand I would record my OC settings, reset the bios to factory defaults with everything on auto so the board reads the SPD and any memory sub-timings in the EPP and determine its own voltages, put in my memory main timings and reboot, put in my OC FSB and cpu mulitplier and reboot, see where the board "thinks" voltages should be set at and start testing with an eye to reducing them as typically they are a bit high for my tastes but you will just have to compare to your current settings and make that call yourself. (Turn off the C1E, memory performance set to normal, etc after the factory default reset)

I don't think so, it is a new build.

Why send it for repair if it is an overclocking stability problem?

I can't tell, but I can imagine that it happened during reset....when else would it change?

I have the latest BIOS

Even if there's nothing wrong with the system, on some boards the CPU clock is reset

It reseted to default almost every time it did this.

This is my memory:

And when my mobo is on auto, it doesn't tell me what voltages it uses!

Well I am tired of playing "guess what weird value in the bios I have set to make my board unstable", good luck.
