Cuttiing bidges on ceramic MP

[ken008]

I am trying to to fool my pair of 1gig MP`s into thinking they are 1.2 or 1500 MP`s . These the ceramic. I am getting nowhere with a knife.What is the best way to cut these bridges? I have heard of the AT 5v power supply trick, it sounds scary. What is the saftest method? Has anyone tried this with MP`s ? I have an unlocking kit . I am pretty sure these processors can handle the higher multipier. They take 150fsb with no problem at all.

arent mp's unlocked to begin with?

cant you change the mult in the bios or dip switches or jumpers?

Not with a Tyan tiger MPX. I am using software to bump the FSB. Altering the L3`s is the only way with this board. It has nothing in bios to change either one.

you dont have dip switches/jumpers either?

if not
you could take a drill with a titanium bit, (a very SMALL titanium bit) and just barely scratch it away
dont dig into the ceramic however little scratches are ok, but dont go too deep
if you go deep, you are pressing way to hard as the ceramic is a tough mofu and hard to drill through (people making dead tbirds and such into keychains found out )

or try with an xacto knife

Go to dentist and ask for a used "diamond coated" rotary burr. You ask the dentist cause he has the "finest pointed", smallest conical angled ones, which you need to cut across the very short bridges without completely obliterating them. Then epoxy into suitable tube for use like surgical tool or pencil. Cut bridges crosswise with fingers motion like writing number "ones", heel of hand resting firm on bench/table. NO power tools. Inspect progress frequently with eye loupe, doesnt take long, ceramic is no match for the diamond coated surface. If dentist does not oblige can find similar in hardware or hobby shops, but very fine tips are what you want. Faced with stubbier tips, we originally ground away "one side" to convert the tip into something like a jeweler's screwdriver with the unground side creating a diamond coated "edge". Later got the ideal shape from dentist, both epoxied into same tube.
