pencil mod

I didnt read the post on the links but ive seen this on video cards before,
basically to lower the resistants of a resistor you can use a graphite pencil
since graphite will conduct electricity and " draw " across the resistor from contact to contact, this will create a second path for current to travel. this will let more current flow from point A to point B.

The more graphite you leave on the resistor the less the resistance will be.
 
i know about the old graphite trick where the multiplier was locked but people drew a line on the processor which allowed the processor to change the multiplier. this seems different though, what is all this vdroop and crap
 
vdroop is a voltage drop while the CPU is loaded.

You can mod most if not all motherboards. This same process wont work on them all though, you have to have the right set of parts (resistors, capacitors, etc) to add or know where to mark with your pencil.
 
there has to be some negative effect to this... why wouldnt the mobos be made like this

and why does vdrop occur otherwise? psu, mosfets ? i dont get it?

Yep, Vdroop is really a pain. Pencil mods, IMO, are rather risky unless you know what you are doing.
 
If you are overclocking, when you increase the voltage, it will actually be what you set it to. IE, if you put it to 1.5V in the BIOS, it will be 1.5V, not 1.42V
 
so how does one screw this mod up?
isnt it just safer to turn the voltage up 1/20th of volt?

Not really because the drop is only while under load, which is why overclockers hate it. If you raised the voltage to compensate for it (which is what's happening at stock speeds) then you run the risk of having the voltage too way high and wreaking the CPU.

i mean where is this free energy coming from?
