Ok...... Now on with the info! The is a guide to overclock with the
Trigem Florida C/TG/TGA and may work with the Trigem Como3 (no info
to prove for fact it uses this pll-ic). This can be used in combo
with the Semtech SC1164 & SC1165 DC/DC Converter Mod on the Florida
C/TG/TGA to provide better overclocking stablity. This is guide
part 1... there will be a part 2 in the future. Part 1 Is limited
to the pll-ic's limits. 83.3MHz is the max FSB that can be set using
this method. Stablity at 83.3MHz is questionable due to as far as I
can tell AGP will also be running at 83.3MHz.. however ICST was nice
enough to have the proper 33MHz PCI clock at a 83.3MHz FSB. This mod
WILL NOT work on all motherboards using the ICST 9148-08 pll-ic.
This is due to the fact that this pll-ic can have the FSB set via
two ways. Jumpers on FS0/1/2 or Bits 4,5,6 of Byte 0 during boot.
Its Bit 3 of Byte 0 that tells it to use either to use jumpers or
bits. But dont worry because if it uses bits youre still fine as
you can use any SMBus accessing software such as SoftFSB or
CPUCool/CPUFSB to access the pll-ic via the SMBus and modify the
FSB. Im sorry I have no pictures of my modded 9148-08 as I didnt
solder anything onto the board as 1: My soldering skills suck
(and Im in need of a new fine tip) and 2: This was just to test
if this worked before going onto part 2. Part 2 will in theory
have no limits. For my testing I just held a wire on said pen
with a 10k resistor inbetween while the other end was connected
to a common gound (I used the ground found in the middle of your
everyday molex plug comming out of your power supply). There will
be PLL-IC shots of Part 2 if it works. I feel kind of stupid as
this was my orignal theory however during my first testing I made
the mistake of not grounding out FS0. If I would had only looked
closer at the papers back then I would have noticed this and
posted this some time last summer!... oh well we all make mistakes
eh... blah
Tools Needed:
1x Soldering Iron
1x New very small/fine tiped solder tip
1x Some solder lead (rosen core not acid core!)
1x 10K Resistor.
Small wires or something to connect pins.
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 have tested this on a Trigem Florida TG Rev. C that has
the ICST 9148-08 PLL-IC. If you do this and also find it to work
please email me at:
enigmadeadsouls at yahoo dot com
(replace "at" with "@" and "dot" with "." I do that so the spam bots do
not pick up my email address).
Send me pictures (keep them small) of your moded ICST 9148-08 PLL-IC
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 ICST 9148-08 Pin-out.
Here is a picture of the supported clock speeds.
Here is a picture of the Mod. See what Ive done is a jumpering setup.
What you will do is connect wires to pins 7/fs1, 8/fs2, and 26/fs0.
these wires will have a 10K (use no less than a 10k resistor) bewteen
the wires connected to the pins and the wire connected to the center
pin of the jumper block (see picture). We will use pin 1/vdd1 to set
logic 1 (however chances are due to the connection to vdd via internal
resistors on pins 7,8,26 leaving it open should also set logic 1).
We will connect a wire to pin 1/vdd1 and connect it to one of the pins
on the three jumper blocks. Now connect a wire to pin 45/GND (any GND
will do) and connect it to the last pins on the jumper block. It will
look something like this
Red = 1, Blue = 0, Purple = FS0/Pin 26, Dull Yellow = FS1/Pin7, Green = FS2/Pin 8.

Test CPU Benchmark data - Use this with TestCPU To compair my machines
to yours. This has data from 3 of my machines.
1: Zero System HP, 2: Zero System E, and 3: Zero System ML (the test
machine for this project). Send me your TestCPU data from your overclocked
ICST 9148-08 modded machines and Ill add them to here. Please only
machines that use the ICST 9148-08 pll-ic. Yes I know Zero System HP
doesnt use this pll-ic.. however its there for comparison reasons.
