P5B-Lux: Clear CMOS jumper needs lots of time. Why?

post #1 of 4
Thread Starter 
So lately, I've been seeing how far I can push my RAM with a x7 CPU muliplier on my P5B-Lux.

Whenever I get it too high, and if my timings are too tight ... then the system won't start and I have to use the clear CMOS jumper (CLRTC) and it works just fine ...

But, WHY do I have to leave the CLRTC jumper jumped for two or more hours to actually become bootable again?

The manual says 10-30secs or something and so, even then, leaving it jumped for 15 minutes would seem adequate ... but in the worst cases, I've had to leave it jumped for at least 2 hours to become bootable again.

I mean ... what goes on in there during those 2 hours? What traces of this or bits of that have to ever so slowly leave the system for it to be workable again.

It's utterly fascinating to me.

Anybody have comments?

When you move it, try cycling your PSU (flip the on and off switch a few times while still keeping your computer off.)

If that doesn't work, on my P5N-E, I would set the jumper to clear and turn the rig on, it'd beep a few times (from being unstable and not-bootable, not from the jumper) and then I turn it off, put the jumper back, and it was cleared.

It would clear within 10 seconds 90% of the time, but other times it wanted to be stubborn and I had to do that.

Do you remove the CMOS battery also? Maybe try that.

I remove the battery of course ... and I'm really alright with having to wait ...

But my main questions is what exactly goes on at the circuit/machine level to require such time.

How long can electricity take to leave/move or whatever happens when you clear CMOS ...

It's just baffling to me and was wondering if any more technically inclined folks could explain the phenomenon, ....
