MSI Afterburner GTX 770 Core Voltage question

[ManOfDisguise]

Im a total noob when it comes to OCing but Im just watching JayzTwoCents video on how to overclocka GPU and his 680 in the vid has +100 max core voltage. Isnt it weird how my 770 has only +12 when i slide it all the way to the right? Also when overclocking I can just leave memory clock at default as Jayz said right?

You can't change the voltages on 6xx or 7xx series nvidia gpus (only very few exceptions).

I OC'd the hell out of my memory. You can too.

Its realy sad that the gtx 770 is locked to only +12 ;(  Nothing to do about it.

already tried

the only other thing you could try would be to edit the bios, but without dual bios you run the risk of bricking the card

[R4STABAN]

Editing the bios is pointless if the card has the reference voltage controller (richtek? I forget..)

 

The card is hardware locked to 1.215v which reads as 1.175v in software.

you need to download the Afterburner Lightning edition beta version. Keep in mind that its expired but if you change your Windows date to Nov 1st open Afterburner then change it back it will work until the next reboot or shutdown. I got mine running overvolted to +100. My results stable are +100 core clock and 500+ memory clock. Here is the link http://www.guru3d.com/files_get/msi_afterburner_beta_download,17.html

Just so people know, this is for 680/770 lightning which uses a non reference voltage controller and is supported by afterburner.

 

No idea if there is a 'backdoor' way for the 780 lightning.
