[Official] MSI GTX 680 Lightning Owners Club - Page 126

post #1251 of 7827
Just did a run on my 680 with the new Afterburner. Started out easy. Going for more now. This was 1342/3454. Voltages: +0 core, +40 memory +20 aux. Not bad to start if I do say so myself.

80.04.09.00.F7 is the non-LN2 BIOS (the BIOS that you get when the card is switched on the non-LN2 mode), and is the version that is available for DL on techpowerup! This version is not what you want. You want 80.04.09.00.F8

EDITED to correct 80.04.09.00.F8

Great info, thanks! Might be good to put that in OP as well thumb.gif

Implying overcurrent protection is still active on these cards?

I am not sure, I don't think 3d mark is hard enough on the card. Most of the bench the card was at 1.24-1.27. I will try Heaven and see what happens. I only have it set to 1357 right now. and + 575 on mem

Well, I've got BIOS 80.04.28.00.3a :|. Glad I have that knowledge out of the way atleast.

Anyone mind posting a detailed description of how to flash the BIOS? Never done this before smile.gif.

Open a dos window and put all of the nvflash files and .ROM in the same directory. Make sure that you change to that directory.

Then simply do nvflash filename.ROM

Hmm, There is no overcurrent throttling, but you can't go past 1.35V-1.4V. If you're referring to overcurrent protection in terms of not letting you go past 1.4V, no card will ever let you do that unless you do a hard mod.

The overcurrent protection most people talk about is where your clockspeeds lower if you reach your power % threshold. On other cards if you reach 120-133% (whatever the max is), clockspeeds will lower. This does not happen on the lightning on the LN2 BIOS. But I think you mean something different - right now it goes up to 1.35V-1.4V via software (tested with a voltmeter). You can;t go higher than that or you really do put the card in danger of frying.....

Wouldn't know I don't have a Lightning

Here is a 1362 I just finished same memory

EDIT: Another run this time at 1382. Got artifacting pretty decently so I'll do more tweaks later. I'm impressed with the score and what it can do at 1.23 so far. I'll keep pushing more later.

Aight, thanks. Should I reinstall drivers afterwards aswell?

Dont' think you need to. Just do a cold reboot and you should be set. Once you cold reboot you will be able to apply over voltage with 2.2.3.
