Instruction to remove a DIL- or PLCC-Chip out of a socket:

DIL/DIP-Socket:

Mainboard with DIL-Socket	DIL-Extractor

Removal: Use a professional tool like the DIL-Extractor. If you don't have one, you can try it with one or two short and small screwdrivers. Pull the screwdrivers into the gaps between socket and chip, and pull him carefully out. Be careful while removing the chip! Use both ends of the chip to pull him out. You'll need some strength, but it might works.

Installation: A DIL-Chip has on one of his small sides an impressed marker (see picture), and the DIL-Socket in most cases too. If the socket has no marker, take a look on the printed circuit board, to find the number "1" around the socket area. Put the chip's marker and the socket's marker on top of each other, or the chip's marker and the number "1".

After installation: boot the PC, enter the Bios-Setup and load the "Default/Optimized Settings". If your PC don't start, please read our BIOS-FAQs!

PLCC-Socket:

PLCC-Socket	PLCC-Extractor	Paper clip

Removing a PLCC-chip without a professional tool like a PLCC-Extractor could be very difficult.

Removal with PLCC-Extractor: insert one hook (middle picture, red marker) into the socket slit (left picture, red marker). Now do the same with the other hook. Press the Extractor against the socket and press at the same time the 2 Extractor legs (middle picture, blue arrows) together. Attention: don't pull the Extractor, press only the 2 legs together until the chip comes out!

Removal without PLCC-Extractor: you can try one of these very little screwdrivers, or a curved piece of wire. Another way is to use a paper clip. Take one or two paper clips and curve it to 90 degrees with a length of circa 2 millimeters.

Installation: A PLCC-Chip has one flat corner as a marker (see picture), and the socket in most cases too. If the socket has no marker, take a look on the printed circuit board, to find the number "1" around the socket area. Put the chip's marker and the socket's marker on top of each other, or the chip's marker and the number "1".

After installation: boot the PC, enter the Bios-Setup and load the "Default/Optimized Settings". If your PC don't start, please read our BIOS-FAQs!
