Ok, Thanks for that, Seems like it has to do with taking things to the limit,As its not happening at the level I have it now.

To elaborate a little (in my simple understanding of course), the CMOS chip is made up of part volatile memory (loses data upon power loss - like RAM), and part non-volatile memory (retains data when power is lost - a bit like the memory on an SD card or MP3 player, as it is re-writable).

The data needed to boot the PC is stored in the non-volatile memory (if this data was ever lost the board would not boot), this also writes default settings to the volatile memory if there is no readable data present.

Your personal settings (FSB etc.) are saved to the volatile part of the CMOS. This is kept alive by the CMOS battery if there is no power supply to the board.

The above does not help with the reason you lose settings due to a failed OC. Sorry.

No. :)

The cmos will store what ever settings you choose in the bios. :)

Slipstream, I know you are knowledgeable by the number of posts you make, I am trying to decide if that statement regarding the cmos is a thinly disguised clue, Do you have to discharge the cmos at some stage when changing settings?

The mobo is a Gigabyte P35 DS3r. Seems to be ok at 3.56 even when running Orthos, Excuse my ignorance.

Yes. Thinking about it, the budget ASRock does the same with the power-off trick, although there is a dedicated setting in the BIOS for automatic crash recovery, and that's the effect Yeoboy is seeing I suspect. :)

Cheers, Slipstreem. :cool:

That depends. On Asus boards you can either press the power button for a few seconds or unplug the mains cable. Once powered up again and it will default. Nice Asus...Friendly to over clockers...

Yes. Imagine the consequences if it [i]didn't[/i] revert to defaults after a failed overclock. You'd have to remove the battery and reset the BIOS with a jumper every time it happened. ;)

Cheers, Slipstreem. :cool:

It's normally the sign of a failed over clock which means it's not as stable as it seems. :)

Hi, Since building my first o/c pc (c/o first overclock thread) I have switched the pc on and on a couple of occasions the pc reverted to its stock speed, It is running at 3.56 happuily but when I tried setting to 3.8 it would boot up and run but would revert back to stock when next fired up, Probably something simple but as a newbe has anyone an idea please,
