question...I have an athlon xp 2400...in wcpuid the system clock is at 133.64 Mhz with a multiplier of 15 resulting in a 2004.53 Mhz clock speed...this is default obv. I want to know if I could up the 133 to 166 and lower the multiplier to 12 resulting in approximately the same clock speed with no risk of overheating or anything. I don't want to OC it because if something happens I dont have the money to replace it atm. Will this increase temps or cause the cpu to work harder, or would it be the same as it is now since either way its running at 2Ghz?

I figured since my memory is 333Mhz It would be good to have the cpu the same if possible...TIA.

Also, would AMD consider this oc'ing the chip and void my warrenty?
 
Might need to add some voltage, probably not, but that's totally possible. Don't see why not.

And overclocking will void your warrantee.
 
Er.. and yes, this IS overclocking. You're upping the FSB, and that creates a performance boost, if you're still running at the same total speed.
 
so will it increase temps or shorten the life span of my cpu? And what voltage would be safe to use? I havent got a clue on that. I assume edging it up one notch at a time would be a good idea but what is a dangerous level? What should I def not go past voltage wise? And would the stock fan/heatsink be enough to cool it properly? also, in case you need to know, under no load right now...asus probe is reporting 38C...under load it ususally gets up to 45 - 46 or so...sometimes more depending on the temp in my apartment. I know AP isn't completely accurate though.

Also, would it even be worth messing with or will I not really see a performance increase?
 
I would drop your multi to around 11 and up the FSB to 166.
Check that your memory is stable at that speed with Memtest86.
Then check the cpu is stable with Prime95.
If eveything is ok then up the multi and run prime again.
I would aim for a multi of 12.5.
You're upper limit will be around a multi of 14.

Keep an eye on the temps when running Prime.
You really want to keep below about 50C.
But you can get as high as 60C without to much trouble.

As for voltage I'd say about 0.1v more for a vcore of 1.75v is the upper limit if your not going to get a high end heat sink.
But it all depends on how your CPU heats up under load.

Luck........ :D
