Just for overclocking starts...

What are safe to say overclock settings that every 680 Lightning should be able to run on Air for starters?
I do not have much overclocking expirience yet. So some starter settings would be very helpfull from you guys.

Also what is better, afterburner or evga precision x?

The 1200 boost is what all lightnings are guaranteed to run i think.

So what i understood in this thread is to just put the bios switch to ln2 and i have my 1200 mhz set standard is that correct?
post #4434 of 7827
Not exactly, you shoud have 1202~1204Mhz core clock with both bioses by default (no manual overclocking needed). With LN2 bios you should be able to rise the core voltage, whitch will help you to manual overclock the GPU.

I was trying to manually overclock my card with both bioses and noticed that the card overclocks equally !!!!! No matter with which bios i am clocking the card reaches 1333 for the core and 7000 for the memory !!!! My bioses are:
default = 80.04.47.00.18
LN2 = 80.04.47.00.19

I am using MSI Afterburner 2.2.3 and Nvidia drivers 306.97 . The max core voltage is 1.271V (peak value), MSI Afterburner during tests shows 2.242~2.252V

Is there something wrong with my card ?
post #4435 of 7827
Hmmm on msi card it says that the card is clocked with 1110 mhz...
Do you mean boost at 1200?

What i understood is that the ln2 bios clocks the card at max turbo clock at all times... no throtteling down and so on...

Is that correct what i understood? Maybe someone can explain nicely for me once mor :-) It is hard fighting through all these posts...
The first post should be updated with some more information. That would be very nice.

GTX 680 run default and then boost depending on the power target setting and the quality of the chip , eg. the boost is not the same on all cards..
LN 2 BIOS runs at 1202 MHz -so no boost .

From there on you are free to rise the V and try your overclock. BTW I think the first page in OK .

See the first page , you are on the locked LN2 BIOS and you need to flash to the old unlocked 3A one:)

I unlocked my LN2 moment i worked around pushin core, jumps were'nt BIG enough. I too ended up with around 1333 on core with EXACT same drivers. Maybe its the drivers thats holding back? i pushed my power slide and mv all way up and still cant get stable higher than 1333 on core. Didnt worry too much with memory though. Wish to be able to run about 1400 on core for 24/7 use! Main Goal.

With AB 2.2.3 I can max my voltage offset to +100mV. I have read that modyfing AB can increase this voltage offset more but I can't find the instructions how to do it. Can You please point me to them?
post #4440 of 7827
I do not see real difference between the two bioses, the only way to change the things is to flash the LN2 BIOS with the unlocked "3A".
