Possible overclock problem

I was oc'ing my processor today, (AMD Athalon 2500+) to see how far I could push it till it wasnt stable enough to run. And I hit that point at 205x11 so I reset my cmos and now my system wont turn on at all... I press the on button and everything starts up and then it just shuts down after about 2 seconds, barely enough time for all my fans to get up to operating speed. So Im wondering did I maybe fry my processor on the last overclock. Or could it have something to do with my mobo?

I was gonna post this is the amd processor forums but thought that here was more appropiate since my problem arrised when I was oc'ing.

my sytem specs are below, but Ill repeat the essentials:

NF7-S Ver 2.0, AMD Athalon 2500+, 1 GB (2x 512 MB) matched memory pair DDR400(Corsair Platinum series), WD 250 GB SATA HD, ATI Ultimate Sapphire 9600XT, and Running off a new 480 Watt PSU.
 
I tested it out with my older Athalon 1800+ from my other comp, and I got the same results, with it turning on and off in a flash... So would that probably say that its my mobo?? Or could it be something else? I also tried switching the ram and the Vid card with the same results. Any suggestions? :confused:
 
Are you absolutely sure the cmos is cleared? Sounds to me like it's trying to use higher settings/clocks/voltages. I know with my DFI motherboard you can hold insert on boot to boot at stock (or lower than stock) values to fix overclocking errors - perhaps your board has an analog.

If not that - then my next thought is power supply and motherboard (in that order). Swap PS's and see if that helps.

I agree, it sounds like the CMOS wasn't fully cleared... If it's a jumper you have to move around to clear it, try leaving the jumper in the "clear" position for like 10 minutes. If that doesn't work, try removing the battery for a while.

I really doubt you could fry a processor by trying to overclock it to those speeds, the only way I could think of is if you gave it a massive voltage boost - but not just from raising the clock speed to 205x11...
 
Ok I got it, double checked my jumper, and I noticed that half of the metal header that goes on my cmos jumper was broken off so I just replaced it with another header... Runs fine now. Man its crazy how the littlest things can not make it work. Ok Im happy now. :)

Happy to hear it - and you're not alone. When trying to OC my older 2700+ Palomino, I did the same thing but instead of not having a functional jumper - I was changing the WRONG jumper.

Also - note to self - and to know-it-all-buddies around the world, do NOT throw the cmos clear jumper while the machine is powered up.

Yes that would be Bad...

Along the lines of my BIOS does anyone know any good BIOS updates I can use for my mobo, right now I have the most recent version from ABIT'S site. It works fine, just wondering if there are better ones out there.
