Whats the clocks wire involvment?


If that wire is too long what will happen?

Sometimes work Sometimes wont? I heard sound problems..


Should you put the chip in the location that would give you the shortest clk wire ?

The clock is the frequency with which the chip operates at. On chips like the M2 it pulls the clk off of the PS2's mobo. Other chips have a resonator built into the chip so this wire is not needed. Yes ideally the shorter the clk wire the better, and yes you can get sound problems from the clk wire if its not ran right because the frequency traveling through the wire will bleed into other circuits on the PS2's mobo. You want to run the clk wire away from other wires and on a ground plain if possible.

So it only effects sound? if it effects anything

no, it can cause various problems from black screens to not booting back-ups ect. ect.

The worst case ps2 for this was the version 5.

A simple way to ensure that the clock wire doesnt cause any problems is to instead of running one wire from clk point to ps2 mobo run two wires twisted together (twisted pair). connect one wire as normal from clock point on chip to clock point on motherboard and the other from ground point on chip to gold edge around outside of ps2 motherboard. This will give the clock wire a deliberate groundloop which should stop it causing any emc problems with other ps2 circuitry.
