1200 266 t-bird
radeon 64 ddr video card
256 mb cas 2 ram
I got a error message about a overclock error when booting it said to reset the clock speed and offered to enter the bios with f1 command.
I was OCing to 1330, so I reset it to default 1200 133x9.0.
Restarted everything is OK. then later on I get the same message and it resets it's self to 100x 9.0 - 900 Whats going on?
Set it back to 1200 133x9.0 and it's doing ok presently

I have not messed with voltage just sdram cycle length to 2 and enabled fast r-w turn around.
I did not know if post should go here or OC section
Thanks

I don't know much about this whole pc building thing...but my suggestion would be to set it to its default multipliers and get it running. Then oc it later. I don't know if you just set it up and started oc'ing without checking to run everything on the defaults or not?

Set it up and ran it at default for a couple of hrs. before playing with it. Also set to pnp os.
