go first post there you can see it.
but i guess you need to yes.
FOR THE FIRST 5000 LIGHTNING 680s
80.04.09.00.F8 (unlocked LN2)
AFTER THE FIRST 5000, WE'VE SEEN THESE LN2 BIOSs FROM THE FACTORY:
80.04.28.00.3A (unlocked LN2)
80.04.09.00.3A (unlocked LN2)
80.04.47.00.19 (locked LN2)
80.04.29.00.3A (locked LN2)
The first 5000 Lightning 680s that were made shipped with the two BIOSs that are mentioned above. However, apparently NVIDIA has now imposed a new limitation that prevents all other 680 Lightning cards from having voltage control, even with the new Afterburner 2.2.3. These newer 680 Lightnings still have two BIOSs (one regular, one LN2), but the LN2 BIOS is no longer "unlocked" to allow voltage control above 1.175. Thus, if your LN2 BIOS version is something other than 80.04.09.00.F8, you have one of the new restricted cards. If this is the case, you can flash your card's BIOS (while it is in LN2 mode) with the unlocked LN2 Mode BIOS file (BIOS version 80.04.09.00.F8). Download this BIOS file here.
To flash the BIOS, download the latest version of nvflash here.
extract the nvflash files to C:\
save the BIOS file to C:\
open elevated cmd window (hit start button, type "cmd", right click cmd icon, run as administrator)
change directory to C:\ (type " cd C:\ " )
OPTIONAL: type " nvflash --protectoff " then hit enter (turns off any error msg that may result from software write protection)
BACKUP ORIGINAL BIOS: Type " nvflash -b backup.rom " and a copy of your bios will be saved to the nvflash directory
type " nvflash -4 -5 -6 680L_UnlockedBIOS.rom "
wait for it to finish
OPTIONAL: reinstall drivers.
