"The system shutdown due to overclocking"

I have configured the following,

AMD 2800+ Barton
ASUS A7V8X
512MB DDR Cruical 3200 DDR400

I set my settings at 12.5 X 181, the system runs great at around 48C.

As soon as i put it to 12.5 X 182, upon reboot I get no picture on the
monitor and I hear the ASUS Post Reporter say "The system as been shut down
due to overclocking". I reboot, put it back to 12.5 X 181 and its fine.

Is this is as fast as it will go? Am I doing something wrong?

Help!

have you tried upping the core voltage this is quite often needed at
elevated bus speeds

This brings me to my next question:

How do you know when you cannot overclock any higher?

I assume this board has a KT333 or KT400(A) chipset and as such doesn't
have a a 6 divider for the the pci/agp bus. That could be the problem.
Might try setting the multiplier higher and keeping the FSB down closer to
166.

Er Yes it is and No you are not - you have a KT400 chipset. About
180-185mhz is the maximum you can get on the fsb -due to the pci/agp
frequency getting increased as you increase the fsb - as the two are locked
together.

The only option is to change the multiplier to a higher value - if it is a
locked Barton the locking work around is said to work on the KT400 (I have
an unlocked one so I have not tried)

it's a kt400
therefor synced to fsb pci and agp
basicly, you need to hit 166mhz, or 200mhz fsb anything in between won't
work too well
you shoud have a bought the nforce2 ultra 400 based mobo really

Yes it;ll be the pci/agp flaking out.

1150 is the failsafe minimum so you may be able to get more without
hitting the limit. Mine falls back to that if I push it too hard.

If your bios has a fsb/agp/pci divider you will need to set that to
5:2:1 to push the fsb up.

As a guide:

I have a Barton 2000 on a kt333 based mobo and it just about gets to
188 with a few voltage tweeks but 189 wont post.

Even then more serious testing (running memtest86 and burnBX) shows it
needs to be more like to 176 to be rock solid.

HTH

Thanks for the help guys!
