hi,
i have decided to do something really stupid and cut the 7th pin on the processor chip in hope of overclocking my L7500 processor now my screen is always black my cpu and and hard drive start, my ram sometimes starts and sometimes beeps some one help me please

Buy a new motherboard with a faster CPU, or stop being stu...

ur a veteran experienced member on here do u know some one that has successfully done this ? or do u have any advice for me ... thx

nvm it works with one 4gb ram but w/e !!! i have to figure out what to fix now any ideas ?

With a Rework station you could remove the old CPU and replace it with another (faster) one.
Or you can try to resolder the cut pin.
Failing that, get another mobo with faster CPU as I told you before.

actually now my 1.6 L7500 goes up to 2.4 ghz and surprisingly runs alot cooler !!! however can u tell me more on that rework station.

Pretty sure the OP is not actually cutting a CPU pin.

It's whatever chip that generates clock signals. Cutting that pin raises FSB from 200MHz to 266MHz. As a result, your DDR2 667 RAM now runs at 886 MHz, and many RAM sticks don't take this overclocking very well.

To do this properly, you have to get a DDR2 800 RAM and flash the SPD chip so it thinks it's only DDR2 533. Then, it will run at 711MHz, which is below its original rating of 800MHz. All details are in the link above if you read German. On the other hand, since things seem to work out fine for you right now, just use it and accept the risk of memory corruption.

And no, please don't ask me how to do this because I know nothing about the procedure, except that people have done it before.
