MSI GTX 680 Lightning...its here


Recommended Posts

you guys have such little faith ;) has there ever not been an unlocked AB?


its absolute different situation, ive told you ... NVIDIA strictly prohibited software control on GTX 600 GPUs, every vendor has to sign that rule ... if he wants to produce these VGAs ... look at EVGA forum, and ask Jacob Freeman or Kingpin about it ...

Some info straight from Unwinder at Guru3D: http://forums.guru3d.com/showpost.php?p=4357961&postcount=12


Unfortunately there is a lot of misinformation about upcoming 2.2.3 with Lightning support. I'm wondering why some people enjoy making things up and posting rumors like this:


Unwinder isn't the only programmer, MSI works on afterburner as well. It is their custom version of the riva tuner core, just like EVGA with precision X. Asus GPU tweak, Galaxy OC, Precision x, and afterburner are all based on riva tuner core, every AIB maker creates their own custom version of it. Afterburner is MSI's custom version and they do have people working on it from what i'm told.


MSI Germany posted that a new BIOS and revision of afterburner is coming soon, they hinted monday but did not confirm. It should be coming soon in any case.



No, I'm the only programmer working on MSI Afterburner project, it is single man project. And it is physically impossible to modify anything but databases from MSI side because I own source code by the contract. The same applies to Precision and Precision X. And no, ASUS GPU Tweak and Galaxy OC and not based on RivaTuner core. And finally, no, new version will not be launched on Monday because my Lightning is still in the way. So info about launch on Monday is not true.

Tried this just now,

even with the LN2 BIOS, max vgpu I can give to the card is about 1.32V (1.212 + offset 100mv), nowhere near enough for LN2 action but should be good enough for 1350-1400ish on stock fan I guess :)


Already sent my afterburner extreme request to MSI, hopefully they reply soon ;)

And then the really bad news ...


While I was writing this article I learned that NVIDIA just issued new BIOS files to the AIC partners and is frowning upon voltage tweaking outside their limitations. As such all new batches Lightning cards will have BIOSes where their limit of 1.175V is enforced, even in the LN2 BIOS. MSI has to follow that directive or probably face the fact that they will not be able to purchase the GPUs anymore.


This as well includes setting restrictions in the new AfterBurner 2.2.3 (download here)


So while everything as described above is possible it in the end means that only the first batch of 5000 cards will have an OLD Bios that is freed up from the limitation and thus allows voltage tweaking to a certain extent. We can only assume that the old BIOS will spread like a virus to current Lightning owners to give them a little more flexibility on voltage tweaking matters. However you'd also need a special MSI AfterBurner build to support it. And that we do not see happening, due to the limitations requested by NVIDIA.


We understand NVIDIA's point of view on this, really .. extreme voltage tweaking can damage GPUs, and in the end these are returned to NVIDIA. Next to that the complexity of this new methodology is extensive and to a certain extent even unreliable. For NVIDIA it thus is matter of RMA and cost.


The flipside of the coin however is that when imposing such limitation on the high-end GPUs it pretty much kills off the fun for many of you. Extreme performance and tweaks drive the overclocking community and in the end drive the sales of the complete product line.


We do hope this point of view will change in the future allowing the AIC partners more flexibility. But for now you guys will have to face the fact that NVIDIA's 1.175V limitation is a solid fact. But sure, this news is a little bitter.
