Ok...... Now on with the info! This is a mod guide to the Semtech SC11654 & SC1165
DC/DC Converter that is used on the Trigem Florida C/TG/TGA motherboards...
however the info here sould work no matter what motherboard you have as long as
as you have the SC1164/SC1165 DC/DC Converter. This is so you can manualy set the
CPU core voltage so that you can push the cpu a little farther.. I will not explain
how rasing the voltage will help with stablity/overclockablity of a CPU due to
there are many people who have covered this topic already so it would be easyer
for both you and me if you just go to google and search for an artical that
covers this.
This is design to be used with the ICST 9148-08 overclock found on the
Trigem Florida C/TG/TGA motherboard.
Tools Needed:
1x Soldering Iron
1x New very small/fine tiped solder tip
1x Some solder lead
1x Something small enough to pull on the small pin of a SMD chip.
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 Florida TG Rev. C that has
the Semtech SC1164 - DC/DC Converter. If you do this and also find it
to work please email me at:

(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 SC1164 & SC1165 DC/DC Converter
and give me your website info if you wish for me to post it at the
bottom of this page.
Here are some Images of the supported voltages of the HIP6021 DC/DC Converter.
As you can see it supports core voltages of 1.3v to 3.5v.
Note: the one listed as all 1's with the voltage of 0
does just that. It has an output of 0 volts.
Here is a pin-out image of the SC1164 & SC1165 DC/DC Converter.
Just your standard 28pin SOIC.
Ok Im going to give some examples of two mods... 2.10v and 2.50v.. from
these I would expect you to get the idea and figure out how to set other
voltages. I would recomend disconnecting all the "VIDx" pins (pins 18-22)
from the motherboard and connecting them to wires with a jumpering design
at the end of the wire then a connection to ground.. that way to quickly
set 0 you would just pop on a jumper and to set 1 you would just remove
the jumper. It would look sort of something like this...
Heres what 2.10v would look like.
As you can see Pins 18,19,20,21/VID4,3,2,1 are open (1) while Pin 22/VID0 are
connected to Pin 1/AGND (Ground) making them a closed (0).
Heres what 2.50v would look like.
As you can see Pins 18,19,21/VID4,3,1 are open (1) while Pin 20,22/VID2,0 are
connected to Pin 1/AGND (Ground) making them a closed (0).
NOTES:: ALWAYS make sure the computer IS OFF before
changing the core voltage. NOT doing so MAY toggle the PGOOD signal and
trigger the over-voltage protection causing the machine to turn off.

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 youre free to change text
font,size,color background color/image to match youre site. Youre also free to
remove my navigation bar at the bottom of this page as Im sure it would be
pointless on your site... in other words Im ok with changes as long as its not
