EVGA 780i Pencil Mod

post #1 of 12
Thread Starter 
Hey guys,

I get my EVGA 780i in the mail sometime next week.

Before I install it I want to do a pencil mod to it to eliminate/reduce vdrop and vdroop entirely if possible.

Does anyone have a linky to this mod that they used?

Much appreciated!

Also, I won't be using a voltimeter so it will be just trial and error here.

Will be using a mechanical pen.

Not sure if EVGA boards are the same as XFX, or other manufacturer boards (reference boards?).

Rep+ for all help!

nevermind, google is my friend. Found a linky on OCN that seems to bring it home for me. Can't wait to do the mod on it

Man if you attempt to do a volt mod there is no trial and error, you only get one error and then its time for a new board. You will definitely need a voltmeter to do this mod. You can use the pencil vs a hardmod but you still need to measure resistance, voltage, and be able to find the correct points for the mod. You must do a continuity check to trace the path to find the point for the mod. Not every Voltage regulating IC is the same on an exact mobo, nor are the mod points, due to manufacturer revisions of a board. Do yourself a favor and post some pix of your board here, like your initial instinct told you, and have your voltmeter ready

I guess we are talking about a vdroop mod and not vcore, right?

The EVGA 780i is a reference board just like the one from XFX, as long as you don't get the FTW version.
The vdroop pencil mod is quite simple and really helps to get a more stable voltage under load. So just use CPU-Z and some stressing tool, like prime,lynx, and check how big is the drop from idle to load voltage.

I had the same board in the past and the original vdroop is realy annoying, just like all the other nforce ref boards

The only way you are going to get an accurate reading is by using a voltmeter. You MUST measure the resistance as well so you dont overvolt your mobo. You cant just go in blind and say,"oh man, I hope this works!" Where did all the real modders go?

I don't have a voltmeter, so does that mean I shouldn't even bother trying?

I've done the mod blindly in the past and I had no problems with my older Asus P5K

You can shade either of the resistors. They both work the same.

The FTW board uses the same mod The FTW bios even works in the Vanilla board.

Did my first 780i vdroop mod without a DMM and did it with the PC running. Just shaded a little, stop and started P95 to check load and idle voltages, and then shaded some more.

thanks pizza.

Good to know that the FTW and Vanilla boards are the same in that way.

I get my board sometime next week. I'll shade it with the pc on and run LinX or IBT to test under load.

Just shade a little at a time. If you shade to much, just rub your finger over the resistor to remove a little bit.
