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 stability. 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. Stability 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.
It's Bit 3 of Byte 0 that tells it to use either to use jumpers or bits. But don't worry because if it uses bits you're 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. I'm sorry I have no pictures of my modded 9148-08 as I didn't solder anything onto the board as 1: My soldering skills suck (and I'm 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 in-between while the other end was connected to a common ground (I used the ground found in the middle of your everyday molex plug coming 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 original 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 tipped solder tip
1x Some solder lead (rosin 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 you're 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 I've 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) between 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.

Names/Info from people who have emailed me their test results:
Tested by Enigma Deadsouls on a Trigem Florida TG Rev. C and worked.

Test CPU Benchmark data - Use this with TestCPU To compare 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 doesn't use this pll-ic...however it's there for comparison reasons.
