Hi. How to take down the multipier lock in sempron 2200+. for now i set FSB
from 166 to 200 and it work like chrm, but how chage the multipier???

If you are running an SiS or Via chipset, the L5 bridges pencil trick works.
Any other chipset, forget about it.

yes i'm running on Sis741
how far i can get with 2200+ : right now it is on 1800mhz but will 2Ghz be
stable??
i think it's better to change multipier than FSB (right now is on 200mhz)
beause the ram is a DDR400 Kingmax, so i'm afraid to go over 200. Am i
correct?

CPU has 48 to 50 degree of celcius - do U think that 55 will be fine???

u see i dont have 55*C right now , i 've got a 48 and 50*C on stress!!! just
2 degreee diference!
that's why i think that my cooler isn't soo bad. Ofcourse it's not a zalman
league 🙂.
In case of changeing of a multipier: 55 is likely_to_happen, so that's why
i've asked............
I don't know if it's internal or external - it's in BIOS - hardware monitor
🙂 (my gess: external?)
and in AIDA- program

summation: is 55 (on stress) a save value??

PS.how much V get's the ram. And wich Vcore level i have to set 1,7 ??? or
more - right now(@1800 there is a standart value 1,6275 or something)

There's no way there's only a 2C difference between idle and max load using
any air cooled solutions, let alone the stock cooler. If you use a utility
like Everest home, what does it give as idle internal diode and external
CPU? What does it say they are when running Prime95 or FarCry?

but that's not an aswer to my question , right?
Prime is used to stress the CPU and it's says nothing souspecious.
so after 15 minutes of near zero stress diode shows 46*C - u think it's
broken, or what??

Where and how are you getting those numbers? I suspect they are an external
CPU diode reading. If the external CPU diode is giving a load reading of 50C
at stock vcore and 1800Mhz, then your internal diode temps are at least 10C
higher. In my experience, when your internal temps exceed 60C on the XP
processors, you'll run into stability problems as soon as you increase
multiplier, fsb or vcore. Get a decent cooler. A good silent one is the
Thermaltake Silent Boost...only 2450RPM but very efficient. I find the
Vantec good, but some (Wes, I think) have had issues with the TMD fan. The
Sempron stock one is not great for overclocking.

First of all i would like to thank for yours help and advices.

I've tried to do a pencil trick, but i've falied - maybe i've used wrong
pencil.
if U know any more improuvements(mods) to unlock the multipier im all ears.

So i took fsb up to 220 or so, but i had to increase the Vcore four about
+6%
The chip was overheating, on my poor box cooler.

so i have changed the termal paste on it. - orginally it was a thin foil.
futhermore i've removed the side panel of my ATX tower.
the result is a chip on 50*C on stress(45*C idle) and Prime95 passed.
Due to my weak cooling system, and power suply unit i probably won't achive
the 2300.

Right now is on about 2Ghz and still stable.

Ps. i also OC my geforce 9550 - i set both clocks nearly twice as fast as in
Ati orginall specs.
but it's another story.........

thanks once more.

Everything you need to know should be here.

To go over 2000MHz, vcore should be at least 1.65v, and many have to go to
1.75v and higher for higher speeds.

If you have to original cooler that came with the Sempron, replace it with
a TR2-M1 or M3. That should take care of your CPU cooling problems.

i were familiar with this page, but it didn/t helped
as shown on this picture:
http://fab51.com/workshop/asrock/img/modified_sempron-L5.jpg
a closed L5[2] - to make it mobile, but it didn't worked
maybe if i also change the l5[1] to set x24 it would help....
maybe i'll use diferent pencil 🙂
will see

ok i'll take a better look of those coolers.
i've discovered that on 1,65V prime shows errors - but system is quite
stable.

The Sempron core is the same as the XP's, so you should just need to make
it a mobile and then set the max multiplier using L6, but I've never had
the need to do this. Looks like which bios you have determines what you
need to do. I do have a locked Duron 1600 (Also Tbred B core), maybe I'll
play with it one of these days.
