did some checking around for this thread but no..

i´m sure you´ve gotten this question a thousand times
before but here we go!
I would like to oc my Athlon XP2200+ (1800Mhz) 266 fsb
to about 2000Mhz. (or more if stabil)I´ve read that you have to "unlock" the proc? in that case, how?

I would be greatful for a complete guide!

I ran my Cel 600 @ 900 for some time.. until it and the mobo died!
so i´m kinda scared of it happening again

tried some different settings in Softmenu..
currently running in 143x2=286Mhz, x13=1860Mhz
but when raising more, it´s like dead.. not even BIOS
tried to raise corevoltage by 0.025 but nothing
tried changing FSB,AGP,PCI-multiplier from 4-2-1 to 5-2-1 but no..

What about this unlocking buissnes?
if it means i have to mechanically change something, i´m out of it!

Ive got my bus set at 150x2. The chip is running at 1650mhz flawlessly. But I did have to put a fan on the northbridge heatsink and a heatsink on the southbridge chip. Also heatsinks on the video card memory. That stuff was $20 at Frys. Pretty good performance from a $45 motherboard and Kingston Value RAM.

I dont get it, why would AMD what to lock the CPUs like they do? It would attract more ppl (maybe) easily.. like oc ppl. Even tho most oc'ers wont care to mod it.. but never the less why lock the cpu

thanks vegasgmc!

got some good info from that link.
So, if i get this right, after unlocking the proc.
i will be able to set multiplier higher than x13,5?

now i can choose multiplier from like 5 to 22 times in BIOS
but when i go higher than 13,5 it won´t boot at all,
you think it will boot with higher settings if i unlock it?

I´ll be back.. have to try some more before maby unlocking

they lock cpus so you get a Athlon XP 3200 instead of buying a 2500 and overclocking it to the performance of a 3200 and pay a fraction of the price.

I also don't know why they do it. Almost anyone who thinks of ovoerclocking his cpu will go through the unlocking process anyway... it's not that difficoult.

I'm just waiting to see what amd invented for those new Athlon 64 to make us life more complicated.

Uh... no athlon XP tbred-b comes multiplier locked AFAIK

I have have put together five athlon machines and only one of them (Athlon XP Palomino Core) was multiplier locked, all others were unlocked. I know for SURE that the 2200+ Tbred-B is NOT multiplier locked.

I'm pretty sure all T-Breds are multi unlocked; I had a 2100+ Palo and didn't unlock it, it's just a pain in the ***, so I got a 1700+ JIUHB for $50.

is that so.. hmm!
so why doesn´t it run when i set higer than 1866Mhz?
not even BIOS, screen goes blank (turns off).
Any tip's?

You probably have a t-bred A, and there were many of that core that for some reason were only able to obtain a 50-100mhz overclock, and nothing more. Anandtech in the early days of the tbred-a got their hands on a batch of those and wasn't able to OC them past ~1870mhz even with water cooling.
