Hi guys, the Afterburner 2.2.3 official version is ready for you to download. this version supports the control of South Island and Kepler card, if you get the card, you may try to play it.

Changes list includes:

• Revised I2C access API for NVIDIA 301.xx and newer display drivers
• Added core, memory and auxiliary PEXVDD voltage control for custom design MSI N680GTX Lightning series graphics cards with CHL8318+uP6262 voltage regulators
• Added memory and VRM temperature monitoring for custom design MSI N680GTX Lightning series graphics cards with NCT7718W thermal sensors
• Added core, memory and auxiliary PEXVDD voltage control for custom design MSI N670GTX Power Edition series graphics cards with uP6262 voltage regulators

Download

P.S Under the Greenlight form NVIDIA, we try to do the best.

Im still only able to adjust the core voltage to +100mv..
in fact, when i move the slider to +100mv Core Voltage and then hit "apply", it reduces down to +93mv. Max voltage according to GPUZ sensors is still 1.215v for vcore

Great job on the software......increased my clocks slightly, cooler still running so cool, is there another bios for the extreme LN2 at all does anyone know that allows higer than 1.3v

Switch to LN2 mode and see if it makes a difference.

The old BIOS will allow some tweaking, the new batches however are restricted (by NVIDIA).

Hi~
Because the adjust voltage has been calculated, so the final value may be different. Voltage varies with the program loading.
thanks

ive tried both BIOS's... suggestions?

i bought my card a few days after it was released so id think its an early batch. either way, where can i get an "old" bios?

not sure if what youre saying applies in this case.. during a 3dmark11 benchmark run, there is the exact same amount of voltage being fed to the core as there was with AB 2.2.2

this is disappointing.
im still maxing out the same 1.215v during my benchmark runs...
looks like ill need to bust out the soldering iron after all if i wanna bench the card on this setup

I can imagine so ...

well was hoping for +200 or 300 vore as the cooler stays so darn cool

from 3d guru web site

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.

That 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.

well i have control up to 1.215v so i guess i have an old batch (i bought mine the day it was released)
but this is nothing new, I had control up to 1.215v using afterburner 2.2.2.
Unwinder said i wrote the software for +300mv core.. so i KNOW it can be done.

can i contact MSI directly and sign NDA to get the REAL version of AB that will allow +500mv for those of us benching with ln2??

wheres that article in news boss?

plus i see 1.41v in 3d thats very good for software

* oh i see thats with the +300mv options

yeah that was with an unrestricted version of 2.2.3

the version that was just released to the public does not allow for core voltage past 1.215 on the LN2 BIOS

that article is about the worst news possible. now we need some smart person to figure out a variable resistor mod for this card so we can get some real voltage control..

Cowie can u share ur bios and ur msi afterburner with us less fortunate

Hilbert Hagedoorn · 07-24-2012, 11:44 | posts: 17,255 | Location: Guru3D testlab

Guys to be clear, you'd need the old BIOS and a special version of AfterBurner. That last one in particular is in control of MSI.

I'll make that a little more clear in the writeup.

guys band together someone has to have the unrestricted version share plz

heck i turned down abx when an msi engi offered it to me.

but i really want a custom one that has my name on it....thats so cool

sam350 · 07-24-2012, 11:54 | posts: 11

so u have no special version?? just the mass released one? uv gotta have the old bios if uc an get up to 1.4v

cowie · *Last edited by cowie; 07-24-2012 at 12:01.*

no i hard modded my stuff less headaches this time around

did you try any tricks?
you know use nvinspector set 1.18v close then see if ab adds to it?
would be close to 1.30v that way but it might not work with this lightning(

sam350 · 07-24-2012, 12:00 | posts: 11

ahhh cool sorry do u have a guide for hard mods for all us lightning owners out there

cowie · *Last edited by cowie; 07-24-2012 at 12:15.*

no sry, as i said thuo msi engi's will have one out sooner or later
A user tells me its working ok up to 1.35v and another showed a 1440 run in 3d11 cant moan about that...so its not the worst news we could get by far

michaelrw · 07-24-2012, 12:12 | posts: 8

well my multimeter is reading a max of 1.349v during 3dmark11 so it looks like weve definitely gained about 100mv extra, even though GPUZ isnt showing it..

cowie · 07-24-2012, 12:15 | posts: 10,949 | Location: new jersey

dont use software to read voltage thats why msi put the volt read spots there man

Unwinder · 07-24-2012, 13:23 | posts: 10,370 | Location: Taganrog, Russia

A few things to keep in mind while overvolting 680 Lightning / 670 PE:

1) Even considering that it is showing you the same +100 as before, it is absolutely not the same overvoltage mode like on reference 680. On original 680 adding +100mV offset is done via NVIDIA driver and it just moves clock/voltage mapping curve a bit, limiting the maximum on NVIDIA driver level (1175mV on regular cards or 1215mV on Lightning with previous Afterburner versions). 2.2.3 deals with voltage regulator directly and it adds +100mV to any voltage commanded to VRM by NVIDIA driver. So under load it results in 1215mV + 100mV VID.
2) You cannot use GPUZ to monitor voltage control on 680 Lightning / 670 PE. Currently it shows target VID read from NVIDIA driver on these cards, it needs to support advanced VRMs of 680 Lightning / 670 PE to monitor proper voltage. Use DMM to control voltages.

Why are nvidia being arseholes about this? The card is well capable of handling additional voltage, they can't apply reference card methodology to aftermarket cards..
