Warning: If you are
here then you agree that I cannot be held at
fault should you damage your hardware as this is
untested/unproven 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 tipped 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 you're discharged of any static
electricity and wear an anti-static wrist strap.
It should be noted I haven't tested this and its
only theory as I haven't 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 recommended 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
modded 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.

You are free to mirror this page as long as you
give me credit and do not change any of the info
unless you ask me first... however you're free
to change text font, size, color background
color/image to match you're site. You're also
free to remove my navigation bar at the bottom
of this page as I'm sure it would be pointless
on your site... in other words I'm ok with
changes as long as its not to the info unless
otherwise approved by me. Also if you mirror it
email me and give me a link and I'll link to it
here.
