Pencil Trick WILL NOT Work!!!

[Remington]

Alright, for some reason I cannot change the multiplyer setting on my mobo.

AsusA7V133A and a 950 Thunderbird.

Last week I could do it, made some changes along the way, and for some reason I can ONLY overclock using the FSB.

Yes, I did change core voltage, and set the jumpers manually, and from the Bios, nothing!

No matter what multiplyer setting I have it on it still set at 9.5 after save and reboot.

Please Help!!

Try a conductive pen or a defogger kit. I used the conductive on my 1gTBird, and it worked just great.

I've asked this question many times before, and i'm going to ask it again:

When will people learn that pencil lead is a RESISTOR.....

[Remington]

So Metaxas, what is YOUR solution, please don't just tell me that the method I'm using is incorrect, and not tell me how to fix the problem.

Thanks guys!

the pencil trick worked great for me first time, use a reasonably hard pencil (HB or harder) and give them a good scribble! Bye the way pencil lead is not a resistor, its not even lead as that was banned years ago, its grannite and grannite IS a conductor. I have had this going for about 6 months now without having to redo them.

Just to clear up any confusion about pencil 'lead' (actually graphite as we all know), it is a pretty good resistor. A quick lesson in physics - which'll no doubt bore most people:

(Here's the boring bit)
A material can only conduct electricity if there are delocalised electrons present, which are free to move within the material. Metals all have a 'sea' of delocalised, valence electrons, which can move throughout the solid with ease, hence their low resistance. Graphite consists of planes of carbon atoms, packed on top of each other with layers of delocalised electrons between them. These electrons act as the charge carriers in graphite, but as they are delocalised over a more restricted area than in a metal, the resistance of the material is correspondingly higher. While it is true that graphite conducts electricity, it still has a high resistance. A 100kOhm resistor conducts electricity, but it's still a 'good' resistor.
Ok, it gets more interesting here

As current flows through a resistor, the energy expended by the electrons to move through it is released as heat (it resists the flow of electrons, so they have to use energy to flow through). So the resistor heats up. If you want to see how good a resistor the graphite in pencil lead is (by how much heat is lost as the electrons move through it) try this:
Get a big battery (high voltage), and connect the terminals to either end of the lead in a pencil. The graphite heats up quickly, causing the graphite to burn in the air, oxidising to CO2. It catches fire. It's fun to watch, I've done it :-)

Sorry for that last post, I just wanted to pretend that the Natural Sciences degree I'm studying for has some relevance to something ;D

the pencil trick WILL work if you do it properly and use a decent lead. not too soft. i'd recommend HB, and if you get a decent amount if graphite on the bridges it will work.

conductive pens and defogger kits are also good, and are definitely better long-term solutions.

personally, i've only ever used the pencil trick and it's always worked perfectly. the only time i've had to redo it is when i cleaned the previous ones off on purpose.

metaxas, graphite may not be as good a conductor as metal, but it is definitely a conductor.

[MEfreak]

Just to agree with Rob here, graphite, while it is a conductor, is not a good conductor. Just to say that it is a conductor is silly. A 1 million ohm resistor is a conductor! But you wouldn't use that for your L1 bridges, would you? Now graphite lead does not have a very high resistance, but it might be high enough to cause problems when closing the bridges.

I'm not commenting on the validity of usin the pencil lead. I use it too. But some of the dialogue here is incorrect. Just because a material conducts electricity does not make it a *good* conductor.

Also note that most specs for graphite lead resistances are for a whole piece of lead. The resistance increases as the length of hte lead trace increases. So if you keep the trace short, the resistance will (hopefully) be low enough to not cause problems.

Pure graphite is very soft - too soft for mainstream pencil use. It is mixed with clay to harden it. The more clay, the harder the pencil. Trouble is, the more clay, the lower the conduction of the track you make over your bridge.
I would advise you don't use a hard pencil, but use a reasonably soft (HB worked for me) fine bore mechanical pencil. You keep your fine track, but the conduction is higher (and so are your chances of success!). If you are worried about graphite dust getting all over the place, you can gently paint over the tracks with clear nail varnish. Be very careful though, and be aware that this will make it harder to reverse the process should you ever want to.

I needed to re-do the bridges 4 times.Each time I just used a rubber to clean off the graphite (meticulously) and tried again.My advice is to not give up.

And that would be what???

:-) (just kidding - of course)

ok. i dont know if this is just my computer or the whole az11 mobos... or what.... but in order for my computer to overclock inot only do i need to connect the L1s but also ALL the OTHER cut bridges.... not including voltage though, most of the time you dont need to go past 1.75v

hope this helps....

PEACE-out,
ULYSSES

I had a Duron that would go to some multipliers but not others using a pencil. Sometimes it did'nt work at all. Very erratic. Then I paid $8 for a defrost repair kit from the car store and boom worked first time everytime. Get the defrost repair kit. It's better. There are no guarentees with a pencil.

[DamnFast]

I feel so lucky that I have an "UNLOCKED" T-Bird. ;D ;D ;D ;D ;D

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I HAVE ALREADY GREAT QUIALIFICATION ( DURON 650 @ 800, 1 burned duron700 , TB 700 @ 1000, TB 750 @ 1050) IN PENCILOVERCLOCKING, GUYS. SO:
1. Pencil connections are effective , cheap, can be perfectly cleaned, as there was no overclocking (exellent during upgrade).

2. The solution:

A) One extremely sharp HB or better more sharp pen

Soft one version of pencils is too soft ... I mean it will no way connect like :
| | | | .
it will connect like:
UT| .
The result - L1,L2 cache or NPU burn!

B) Connect verticaly , 5 or more passes up and down , layers must be thick.
if you are not sure , if some of the briges are connected wrong or look like connected wrong - take an eraser! Do not risk!!! Or there can be the same as at p. A

C) Again , be sure that there is no ... even graphite dust between the briges! and they are connected perfectly! - perfectly thick and perfectly | | | | . !!!

D) Do not blow on briges to prevent nanometic water drops between the briges , which also may destroy as it is said in p.A, if tere is some dust. Take a fan.

E) Place accuratly into MOBO's socket, do not touch connections!!! Also , do not touch them with your fan.

F) Try overclocking! If there is something strange you set 1000 - it displays 800 - you will have to make more up / down passes.


EnJoy!


P.S. I had to reconnect my Athlon - 6 times until it started working, but that was something!!
Also , SuperOrb is OUTSTANDING FAN ONLY IF YOU HAVE GOOD AIRFLOW IN YOU CASE! Suggested is ATX with horizontally located PB( at the top) , not vertically!
