It's my CPU almost dead?

Hi all, i'm having a "problem", and want need some advise!

I've got an ASUS Mainboard A7N8X-X and an AMD 2200+, ok?

If i overclock the CPU and put the FSB at 166 and the multiplier at 11.5,
the bios report a 1916mhz procesor(or 19xx).

The CPU works great, without any sign of problem, crash, heat(never passed
the 39-43C), etc.

Until Doom3, this game crash very often! So, I read that Doom3 it's very
sensitive to overclock, so give it a try and go back!

If i put the FSB at 133 and the multiplier at 11.5, the bios report a 1800+
procesor (it's ok).
If i put the FSB at 133 and the multiplier at 12.5, the bios report a 2000+
procesor (it's ok).
If i put the FSB at 133 and the multiplier at 13.5, the bios report a 716mhz
procesor, why doesn't put 2200+?
If i put the FSB at 133 and the multiplier in auto, the bios report a 716mhz
procesor, why?
(the memory and volt parameters are set to default).

The strange thing here is that 3 months ago (before the overclock), the
2200+ apeared without problems!

Any idea? If the CPU it's ****, why it's work fine? (forget doom3)

Thanks in advance!

Sounds like one of the lines to set the multiplier is hosed.
In your case it looks like any multiplier above 12.5 doesn't
work. The CPU would still run OK just at a slower speed.
This could be a bad CPU or mother board.

A wild guess, but have you updated the BIOS of the mb. I visited Asus
global site and noticed that the mb do support AMD XP 2200 Thoroughbred
in all BIOSes. If the cpu is a Thorton, it's supported in BIOS version
1005 and higher.

Have you increased Vcore and/or Vdimm? If you have not that is your
problem. You normally cannot overclock these processors and have them
STABLE, without increasing Vcore and sometimes Vdimm.

I'm sorry, i wasn't clear enough. The problem i have, doesn't involve
voltage (i think).
Thats because, my amd 2200+ cpu runs at 1800Mhz, number i can't get!

If i overclock the CPU works fine without touching the voltage parameter. (i
comment the overclock just a reference).

Jim, thanks for your soon answer.

What's the meaning of "Hosed"?
About the multiplier, I will check it later (not at home right now), but I
remember changed the multiplier higher than 13.5 and the MHz changes a bit,
for example from 716 to 9xx (I think), always at fsb 133. So, the multiplier
factor works, but not the math's!
I now realized that I didn't take out and put again the cpu (maybe some pin
doesn't made contact?)

Defective.

If the switch that makes the change between multipliers over and multipliers
under 12,5 is defective, you will see this behaviour. Some configurations
can have 2 meanings. In your case this error means you will get 5,5 instead
of 13,5 when you select 13,5.

Look here:
http://fab51.com/cpu/barton/athlon-e23.html

See under "L3 sysclk multiplier". Is it possible that your CPU has sustained
damage or maybe there is some conductive element around here?
Maybe a good idea to look at CPU pins as well.

Clean the CPU at least.

Is it a mobile? If it's a mobile 2200+ then 12.5 is the max and the cpu will
reset slow from anything over that. Unless you modify the bridges. According
to:

http://www.cpuheat.wz.cz/html/AXP_mu...Multiplier.htm

Unless I'm reading it wrong.

I have a mobile 2200+ at 166 x 12.5 = 2075. I may do the bridge thing but I
never have -- eeeek!

Not sure about non-mobiles.
