Warning: If you are here then you agree that I cannot be held at fault
should you damage your hardware as this is untested/unprove content.
Please note that if you have tired to contact me in the
past using the address below and got no reply, chances
are you were filtered out as spam. So please post your
question to the eMachine Upgraders forum.
Tools Needed:
1x Soldering Iron
1x New very small/fine tiped solder tip
1x Some solder lead
2x 10K Resistors
Some Small wires.
Some free time.
Before doing this you should remove the motherboard from the case and
remove everything from the motherboard (such as cpu and ram and such)
just to be safe and for extra free space. Make sure youre discharged
of any static electricity and wear an anti-static wrist strap.
It should be noted I havent tested this and its only theory as I havent
a motherboard with the ICS 9250-38 Clock Generator. If you test this
and find it to work please please email me at:
-e-n-i-g-m-a--d-e-a-d-s-o-u-l-s- -a-t- -y-a-h-o-o- -d-o-t- -c-o-m-
(remove all dashes, replace "-a-t-" with "@" and "-d-o-t-" with "."
I do that so the spam bots do not pick up my email address)
Its recomended you do some cpu benchmarks before and after to see what kind
of performance gain you might have gained! You might use SiSoft's Sandra or
some other popular benchmarking test to get a good idea. When emailing me
send me your test results and screenshots as long as they are under 640x480
and 50kb in size.. also send me pictures of your moded ICS 9250-38 PLL,
and give me your website info if you wish for me to post it at the bottom of
this page.
Here is an image of the Pin-Out of the ICS9250-38.
Here is an list of supported FSB's of the the ICS9250-38
Disconnect FS0 (pin 54) and FS1 (pin 55) from the motherboard and
solder some wires to them and the middle pin of a jumper block with
a 10K resistor inline as shown in the picture. Leave VDDREF (pin 1)
connected to the motherboard but solder a wire to it and then to a
pin on each side of the jumper block. Leave GND (pin 4) connected to
the motherboard but solder a wire to it and then to a pin on each
side of the jumper block.
Now to overclock, using the FSB chart above, if it calls for a logic "1"
on FS0 connect the FS0 jumper block middle FS0 pin to the VDDREF
pin on the jumper block, if it calls for logic "0" connect the middle
FS0 pin to the GND pin on the jumper block. The same hold true
for FS1. Using the above FSB chart as a key it will tell you what to
set each pin to for various FSB's.
