Clearing the CMOS

PilotTait · 4 Mar 2007 at 12:04

I know how to do it, swap the jumper from pin 1 & 2, to pin 2 & 3 then swap it back.

But what does it actually do?
When I start the PC up sometimes i get "please reset the CPU or memory freq in the CMOS" (or something along those lines)

I did change the CPU multiplier, memory timings and freq so I'm guessing that's the issue, hopefully be cleared by this CMOS jumper...?

Thanks

you can also reset the bios to default from bios if you get that far...

clearing cmos resets the settings back to the manufacturers defaults. using reset default inside the bios often doesnt fix problems, phsyically resetting cmos is MUCH more reliable.

Yeah, I agree, tried to do it via the bios but nothing much happened, ill do it via the CMOS jumper

Take the mobo battery out first.

The jumpers will look like this:

O-O O

Move the linker so they look like this:

O O-O

Then wait a minute or so, move the linker back, and reconnect the battery.
