How to unlock Voltage ?
hardmod bios File give me pls

Ty for Helps

Hi friend.

To get 1.3 or 1.4v on the DCii680 you'll need to hardmod your card like so:

http://www.overclock.net/t/1261559/my-dc-ii-gtx680-mini-review-and-volt-mod-info-with-some-preliminary-results-56k-warning

Or VGA Hotwire with an Asus Rampage IV Extreme or Maximus V Extreme motherboard:

You could use this bios to get maybe 50Mhz more out of your card:

gtx680.rom.zip 55k .zip file

It's a very good bios that doesn't throttle.

My bios i use will crash you if over 68c so it wont work unless on water or better

good luck smile.gif

Note that I just circled a random trace...you shouldn't cut the one I circled in the second picture. These traces connect the pads of the PWM regulator chip to the rest of the board. You want to sever them as close to the chip as possible so then you don't have to worry about cutting it too far downstream where it might branch off into other circuits and whatnot above your cut.

You would then connect a very thin 30 awg wire between the right side of the big capacitor (silver|brown|silver part) at 11 o'clock (underneath the text "VID6 is tied...") and the the pad labeled with VID6 in the second picture.

VTT is just +Voltage as far as you care. You want to make VID6 = +Voltage = '1' and VID4,5,7 to be cut off = '0'. Technically you want to connect VID4/5/7 together to ground in order to make sure they're not left "floating" where you don't know what the voltage is. Just because it isn't connected to anything doesn't mean it is 0V.

Cutting the traces would be the easy part. Trying to solder wires to pads that are only .5mm wide is the tricky part.

EDIT: Woops I got my binary mixed up. You would want to connect VID5 to +VTT and VID4/6/7 to GND / Each Other (Since VID7 is already GND).

IF U SOLDER VID4 TO GROUND U CANT NEVER GO BELOW 1.46875V. LOOK AT THE DATASHEET, U CAN FIND IT HERE

Edit: 4,2 and 1 to VTT and other ground and u will get 1.30625V
Edit2: And double check the right pins, they are in my link. And use only legit guide

Hi guys, new member here.

Been searching on the net for a bios I could use on my 2 GTX680 Twinfrozr 4gb OC editions cards that would allow me to increase voltage to get more out of them. Currently Gpu1 is only capable of 1189 and Gpu2 1175.

They are 4gb cards so i was unsure if I could use a reference bios, any suggestions would be appreciated, plus a link to a tutorial on how to flash them.\

Thanks again!!
