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.


Ok...... Now on with the info! This is a mod guide to the Harris/Intersil HIP6021 DC/DC Converter that is used on the Trigem Anaheim2/2A and 3 motherboards...however the info here should work no matter what motherboard you have as long as as you have the HIP6021 DC/DC Converter. This is so you can manually set the CPU core voltage so that you can push the cpu a little farther.. I will not explain how raising the voltage will help with stability/overclock-ablity of a CPU due to there are many people who have covered this topic already so it would be easier for both you and me if you just go to Google and search for an article that covers this.


Tools Needed:
1x Soldering Iron
1x New very small/fine tipped 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 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 HIP6021 - DC/DC Converter. If you test this and find it to work please 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 modded HIP6021 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.

HIP6021 DC/DC Converter Voltage Table

HIP6021 DC/DC Converter Voltage Table

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 HIP6021 DC/DC Converter.

Ok I'm going to give some examples of two modds... 1.65v and 1.75v.. from these I would expect you to get the idea and figure out how to set other voltages. I would recommend disconnecting all the "VIDx" pins (pins 3-7) 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...

Jumpers

Here is what 1.65v would look like.

HIP6021 DC/DC Converter at 1.65V

As you can see Pin 4/VID3 is open (1) while Pins 3,5,6,7/VID4,2,1,0 are connected to Pin 17/GND (Ground) making them a closed (0).

Here's what 1.75v would look like.

HIP6021 DC/DC Converter at 1.75V

As you can see Pins 5,6/VID2,1 are open (1) while Pins 3,4,7/VID4,3,0 are connected to Pin 17/GND (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.
