I hope you saved your original BIOS prior to flashing....Keep in mind, WHEN EVER YOU FLASH YOUR GPU BIOS YOU MUST RE-INSTALL THE DRIVERS! Didn't mean to shout, just wanted to drive that point home. biggrin.gif

Re-load the drivers first, if that doesn't work, try flashing back to the original BIOS and see if the problem persist. It could be a bad BIOS file, or something done incorrectly while you were flashing. If you are using multiple cards, remove them and flash each card seperately to make sure you don't scew up any SLI regestries. At the very least remove the SLI bridge prior to flashing.



^ Give that a try and report back whether or not it solved the problem. thumb.gif

I flashed it, then reinstalled drivers. Issue persists. Should I have removed drivers before the flash? I did it with only one car installed at the time. I have the original backed up as well, so I'll try loading that and then reflashing again tonight when I get home.

just an FYI... the latest version of nvflash works in a windows command prompt.. you do not need to do anything other than put the nvflash files in C:\
then open cmd prompt, run as administrator, then type "cd C:\" to change directory to C:\
then type "nvflash -...." with whatever string of commands you want.. like "nvflash -3 -4 -5" for example
ill do it in a little bit if noone has done it yet

MSI GTX 680 Lightning UNLOCKED BIOS

I just did it myself. I am hosting the BIOS file on my gmail account. Download it.
the actual BIOS Version is: 80.04.09.00.F8
This is for the LN2/Unlocked BIOS. I am getting 1.349v (multimeter reading) during 3dmark11

OCN will not let me upload/attach a .rom file to my posts, so this link is the best i can do.
I will add this link to the OP

So that means I did do it correctly (in theory). Is there something that would cause it to just **** out and artifact all over the place after a flash?

Just curious if anyone's had this issue. I'm running 2 cards in SLI and I'm trying to set the overclock through Afterburner, but one card always seems to be running slightly faster than the other, even with the setting to synchronize the cards turned on. I can't seem to get the cards to run at the same speed no matter what I try.



As you can see there, card 1 is at 1306, but card 2 is at 1267. The memory clocks seem to match up fine though.

EDIT: The card 1 is running faster than what I have it set to, card 2 is running slower (set to 1280MHz)

You should use the LN2 BIOS. Your cards will always stock to 1202 boost with the LN2 BIOS.

Wait your sig seems to indicate you have an ASUS card. There is nothing you can do here, all cards run at different speeds with the GTX 680. Boost speed depends on chip quality, the lightning is the only card different in that respect (they all are stock 1202mhz on the LN2 BIOS..)

This is normal behavior, you are fine - all GTX 680 sli setups (other than lightning LN2) do this.

Yeah, I realize that all cards run slightly different outta the box, but I was just hoping there would be a way to actually force them at a certain clock speed, since both cards are capable of around 1319MHz stable on their own, but in SLI they both start running weird clocks that don't match each other, even with Afterburner set to +78MHz.

And yeah, Asus cards, but there doesn't seem to be an Asus DCUII thread here frown.gif and since I'm using msi afterburner to clock them, figured this would be the best place to look

You could always unsync them and set individual boosts. What you do is go in "settings" and select GPU1 or GPU2 and change your boost per card...

You should be able to get same clockspeeds that way thumb.gif
