How do you unlock the voltage to go above 1.175v for GTx 680 Lightning? I switched the button on the card to the LN2 bios, but then nothing changed. I opened up Afterburner and the max limit for voltage is still 1.175 and the power limit is still 133% (not 200)?

You have to flash to the unlocked 3A LN2 BIOS in the OP of the Lightning Owner's thread. You can't rely on software though for a voltage reading. While you are getting above 1.175v, you're not getting the full 1.36v that the unlocked 3A BIOS has, I can tell from your 133% Power % (unlocked 3A BIOS has 300%). I've been told from someone who also got one of the "new" Lightnings with the locked 3A LN2 BIOS that you have goes up to 1.3v (read from a DMM, Afterburner is unreliable). So flash to that one from the OP in the Owner's thread and you'll have ~1.36v at +93mv in Afterburner 2.2.3. Then if you want to go up from there, you'll have to use the hack.

Hi, I have an EVGA GTX 680 FTW+ LE 4GB card.

I have the ROM for the non-LE card (EVGA GTX 680 FTW+ 4GB). When I try to flash the new ROM I get a mismatched Card ID error. Is there anyway to fix this?

Thanks,

Does anyone have an unlocked top 680 bios asus? Just the default bios with an unlocked voltage. I can't get higher than 1.175V.
post #288 of 333
Hi guys,

I'm trying to figure out if there's a way to unlock voltage over 1.175 with my Zotac GTX680 AMP!. It's a reference board, so I should be able to crossflash other OEM BIOSes without issue. Any thoughts?
