Hi,
 
So I switched over to a Gigabyte board, and noticed they use a jumper to clear your CMOS versus the handy button EVGA provides. Instead of fumbling in my case for BIOS updates, hardware changes, or overclocking failures, I figured this a useful investment:
http://www.silverstonetek.com/products/p_contents.php?pno=clearcmos&area=usa
 
So here is a layout diagram of the Gigabyte board, the CMOS jumper is in the lower right:

On the motherboard, the top pin for the CLR_CMOS jumper has a "1" next to it. Other than that, there is no other labeling on the board nor in the manual.
 
Here are the pins on the Silvestone product:

 
QUESTION: Is it safe to assume the "1" on the motherboard refers to the "CMOS 1" red wire on the Silverstone product? 
 
I also forwarded this question direcly to Gigabyte, so will update with their response as well. Many thanks in advance for your help.

    I'd assume that the "1" on the switch goes on the "1" pin on the mobo. Try it out, the worst possible thing that can happen is that it doesn't clear the CMOS.

    Got some stuff in a plastic box that's makes my screen turn on when I push the button on the front, cool.
     
    I think it's aliens, but I'll have to confirm with voodoo do-er on that.

    Its going to be annoying;
     
    The CLEARCMOS switch is wired for a 3pin header where there is a "Normal" position and a "Clear" position.  You'll need to figure out which pin on the 2pin connector is the common for the reset switch's 2 positions - it should be pin 2.  Once the common pin is found, you connect it and pin 3 to your Gigabyte's CLEAR CMOS header.

    Well, the jumper should be on the mobo right now, in the normal position. So, place the 1~2 connector on those two pins, and the 3 connector on the bare pin. Seems when you push the "panic button" the CMOS gets cleared.
     
    There are 3 pins here, and basically only two ways for this switch to be "installed", you have a 50/50 shot at getting it right the first time, and the only problem that could possibly occur, should you get it wrong, is that you clear the CMOS.
     
    Alrighty then, pull up yur socks and get er done.

    The motherboard does not come with a jumper believe it or not (I guess I can, $530 board didn't even come in an anti static bag nor do the RAM slots have that nice sticker over them to protect from any dust particles like EVGA's do lol).
     
    From reading the literature, I got the impression if connected improper, it could damage the motherboard.
     
    Here is the manual: http://www.silverstonetek.com/downloads/Manual/Multi-CLEARCMOS-Manual.pdf
    @dhemke, The motherboard only has 2 pins for the clear cmos, not 3. 
    @Fiius, You are saying pin 3 will be used and I will use half of the 2 pin part? Here is the manual's table on the pins.

    I appreciate your patience and thoughts. I am still working on my case and preparing to finish my build. I am not quite ready to connect everything, I am just trying to get informed before I get there.

    OK - after spending some time playing translator for that Silverstone manual, you can plug in the 2pin connector only and it should reset the board when the switch is moved from Normal to Reset.
     
    You can doublecheck my work by either temporarily plugging the 2pin into your front panel power switch connector, or by tracing the wires back; make sure the 3rd pin is on the same side as the Normal position on the switch.  If you connect it to your front panel power switch, the computer should turn on when you toggle the CLEARCMOS switch to Reset.

    Wow, what a joke, took forever to dwnld 34 pages of your manual. Gigabyte needs a faster server.
     
    2 pin Clear CMOS, no probs, forget the number "3" connector, it's useless to you, not needed at all in your situation.
     
    Anyhow, with the jumper off, your mobo/CMOS is in "normal" mode, jumper on it clears.
     
    Too easy. The switch is set up for a 3 pin mobo, so no matter how you look at it, in one position the switch is closed between the contacts labelled 1 and 2, in the other position it's open. Orientation of the connector on the pins does not matter, this is a simple switch, it is either OFF or ON, polarity is not an issue. I can assume which is which, but let's not do that, $350 assumptions are not all that bright.
     
    Grab a multi-meter/ohm-meter, place a probe in each of the switch's connectors, as in one of the probes in "1" and the other in "2".
     
    Set your meter to ohms/resistance.
     
    It does not matter what the label on the switch says, when you have ZERO resistance, the switch will be set to Clear CMOS in reference to your mobo. Mark the switch as such, so you don't forget.
     
    Move the switch to the other position, you should have INFINITE resistance, that would be NORMAL in reference to your mobo, mark the switch as such.
     
    Move the switch to NORMAL, as in the position you marked as "normal" on the switch. Connect it to the mobo. You're set to go.
     
    When you need to clear the CMOS, shut down, turn off the PSU switch, push the power button on your computer(fans will probably spin briefly), disconnect the power cord from the PSU, move the switch to where you marked it as CLEAR CMOS. Leave it there for whatever amount of time your manual suggests(probably 30 seconds or so), set the switch back to "normal", and you're done.
     
    Piece of cake. This WILL work.
