All questions for bioses/benchmark results/overclocking technique/etc. for the GTX 770 Lightning go here. I will try to help you out as much as I can.

Edit: I have recently swapped the thermal paste on the card with Coollaboratory Liquid Ultra, and my temps have dropped ~9–10°C.

My own overclocking results (LN2 bios with Afterburner 3.0.0 Beta 18):

Core Clock: 1240
Boost Clock: 1290 (decreased 2MHz through bios mod)
GPU 2.0 Boost: 1333
Memory Clock: 8100 (decreased 10MHz [effective] through bios mod)

Afterburner settings:

Core Voltage: +130 (increased with mod)
Memory Voltage: +100
Aux Voltage: +50
Power Limit: 150% (increased with bios flash)
Temp Limit: 95°C (prioritised)
Core Clock: +90
Memory Clock: +550
Fan Curve: 5%/0°C, 100%/75°C

Unigine Heaven 4.0 (highest settings possible, no 3D, single monitor, 1920 x 1080): 44.8 FPS, highest temp: 77°C after 3 loops.

When gaming for several hours, my peak temp was around 77°C (on air). Note that this is around 5°C hotter than when the card isn't overvolted.

The mod I used unlocks the voltage control completely, so it is, in equal parts, both useful and dangerous. If you use this mod, make sure you follow the instructions 100% correctly. I, personally, would not go above +130 on the core voltage, as this is ~1.3V. On air, that's as far as you want to push it.

Anyway, here's the link: http://www.overclock.net/t/1398725/unlock-afterburner-l...

Let me know what you other owners of the GTX 770 Lightning/770 in general find. :)

As far as I'm aware, and for those of you who don't know/are unsure, setting all voltages to max is the maximum safe voltage allowed by MSI.

I have found that the nVidia 320.49 WHQL driver is the most stable driver for the 770 Lightning. I tried the new 326.80, but I got lots of crashes on the stable overclock I got using the 320.49 WHQL driver. Just a heads up.

Yes, there is a thread somewhere (although, I can't find it now for some reason), in which people have been flashing their 680s with 770 LN2 bioses. Basically, it unlocks their voltages to 1.3V, etc. I'm not sure whether you get the 94°C threshold with that, too, but some people have been getting great results with their overclocks! :)  This (http://www.techpowerup.com/vgabios/141424/msi-gtx770-20...) is the LN2 bios, if you want to have a go at flashing your 680 (I take it you have one?). Although, I highly recommend finding that thread, and I take no responsibility if it goes wrong!

A lot of people have been bitching (probably, because they have a 680), that the 770 is just a 680 with a new name. This isn't true at all but I'll just let people think what they want! :)

no im buying a new GTX680 lightning and was wondering about it instead of buying the 770 lightning which is $200 difference! so iwas thinking of doing the flash on the ln2 bios

Yeah, the bios flash is definitely possible (assuming you do it correctly, natch). You probably won't be able to overclock the memory as much as the 770 Lightning, but, for price-to-performance, that is definitely a smart move. :)  Good luck!

hey there...
I recently purchased a 770-Lightning, and I am using it with latest drivers R331 in Win8.1...
I am using stock bios that came with it and tried drivers since 320 till 331... Using Afterburner beta15 but any other software tweaking doesnt make a difference for me...

my graphics keeps getting crashed and restored by nvidia panel, if I am trying to overclock the core frequency more than +20mhz...

here are the fast settings.
Core Voltage: +100 (max)
Memory Voltage: +100 (max)
Aux Voltage: +50 (max)
Power Limit: 109% (prioritised)
Temp Limit: 95°C
Core Clock: +20
Memory Clock: +200
Fan Curve: 40%/0°C-40°C and 90%/90°C-100°C

After starting Heaven test, it keeps crashing either in the 1st scene or the 2nd if I'm over +20mhz...
maybe you can give me some ideas...

so, it looks pretty stupid at this point, if I cannot overclock "Lightning" why the hell I am paying extra for this lol... I am actually thinking to return this and replace with reference 4gb at this point, or maybe Asus DC2O since its like 100$ cheaper in my country...

Have you not set the bios switch on the card to 'LN2'? You need to do that, to unlock the core voltage!

aah... you are right, I actually cant push more than +12mV to the core... This is where I got confused probably... I'll try this too when I have time...

By the way, without changing the voltage switch I could actually push the card by +24mhz without crashing heaven or valley. It seems kind of stable now. Will see what it can achieve later with unlocked voltage.

by the way with core frequency raised by 24mhz and memory frequency raised by 200mhz, I could achieve 41.7fps in heaven. and 51.1fps in valley...

well gaming is usually lighter duty compared to bench'ing... I'd like to see heaven results if possible. Because even if I switched to LN2 bios, which I believe is the same bios with the default one anyways, doesnt make any difference and I keep crashing in heaven test if I push the core freq. above +24HZ.
as a summary, I've been using the latest drivers/bios/afterburner and defaut/LN2 bios, I cant push the card more than 24MHZ at core. Well the valley bench works fine, but dont understand why heaven doesnt...

I'd like to accept the fact that Heaven bench is way too overloaded and unstable, but I believe in any extreme conditions a gpu shouldnt crash with overclocked values, which happens to be my "stable system" view...

LN2 bios and default bios are not the same at all. You need to set the card to LN2, by physically switching it on the side of the actual card. You need a version of Afterburner which allows you to overvolt your card (which, as of two days ago, there isn't a version of Afterburner which works). You need to go into the settings of Afterburner, and check 'Unlock voltage control' and 'Unlock voltage monitoring'. If you have the LN2 bios set, you have the Lightning Edition of Afterburner (which is made specifically for Lightning cards), and have checked the voltage settings, you should be able to push 100mV on the core, 100mV on the memory and 50mV on the auxiliary. If you can't get this to work, you have 100% done something wrong.

If you haven't overclocked the card at all, and Heaven is crashing, you have a bad card, and it's time to RMA it.

I can run Heaven, any game, OCCT stability test, etc. without crashing. I am overvolting my card with +125mV now using a program (http://www.overclock.net/t/1398725/unlock-afterburner-l...) which, coincidentally, allows you to use Afterburner beta 15 for Lightning cards, even though it doesn't actually work usually. I can now push my core to +85Mhz without white dots in Metro: Last Light (which is confusing, as I thought heat caused white spots. In my case, it seems more voltage has stopped those artifacts).

Well thanks for explanation but I'm aware of those settings already but let me start from the beginning...

I actually have switched to LN2 bios physically before, while using afterburner beta17, I also unlocked all the voltage controls. As you explained I am able to push the voltages and power settings to their maximum values allowed. But, still pushing the core frequency more than 24mhz makes my card crash in Heaven test. There are no problem with temperatures btw as they are always below 68C.

So, I did some research and what I'm trying to say is that LN2 bios is almost the same with default bios. But the only difference is the solution for "cold-bug" which is specifically designed for sub-zero temperatures if you are going to use LN2 cooling (liquid nitrogen cooling). In LN2 cooling your card is below 0C (while on standby or shutdown mode) and the card needs to operate between some above-zero temp. If its sub-zero temp card does not start up as intended which is called the "cold-bug". So, other than this solution there is no difference to me, as I experienced that I cannot raise the frequency as it is supposed to happen.

Well, if you have any other ideas, Im gladly open to any suggestions lol. thx for reading.

Edit:
By the way, my card is overclocked by +24mhz to the core, and +240mhz to the memory, and it works without any problems in any aftermarket benchmark test.
But you know, as an owner of a Lightning card I am expecting more overclocking power and less limits obviously. Well I'm starting to that I have a bad batch for overclocking, but generally card works good even while slightly overclocked.

Ah, there you are, you are using beta 17 which doesn't allow you to overvolt the card! The LN2 bios allows overvolting via Afterburner; that is the main difference between the bioses. Like I said, the problem is ATM there is no Afterburner that allows you to unlock the core voltage. Literally two days ago there was a version that worked (beta 15 SE was the only version that allowed overvolting). You need to, either, use the program I linked above, or wait till the next Lightning version of Afterburner is released--which could be days/weeks/months). You need to push the core voltage to, at least, +100mV. You simply cannot do that with beta 17. The reason you cannot overclock more than +24Mhz to the core is: You haven't overvolted the core yet! I can't get +85Mhz on the core without +100mV let me assure you!

Hey there fellow Lightning users,

Thanks to the update in MSI Afterburner Beta 18, finally we all can overclock as we should...

With the final updates I am finally able to overclock my 770-lightning... Here is the latest results:

LN2 bios + Latest WHQL drivers
Afterburner Settings:
Core Voltage: +100mV (which is the limit, unless you mod your bios)
Memory Voltage: +100mV
Aux Voltage: +50mV
Power Limit: 109% (priority)
Temp Limit: 94°C (linked to power)
Core Clock: +100MHz
Memory Clock: +400MHz
Fan Curve: 40%/0-40°C > 80%/80-100°C
*extended MSI settings
*forced stable voltage

It was finally great to see the potential of my Lightning card, I was actually fed up with stock or very limited overclock setups.
I was able to use the card in games and stress tests, without problems with the settings above, but even with the fastest fan settings the card gets a bit hot and hits 78-80°C in Valley bench.

So I decided to back down the clocks a bit, but Voltages and Power were kept at maximum possible.

Here is what I use in a daily setup:
Core Voltage: +100mV
Memory Voltage: +100mV
Aux Voltage: +50mV
Power Limit: 109%
Temp Limit: 94°C
Core Clock: +75MHz
Memory Clock: +350MHz
Fan Curve: 40%/0-40°C > 80%/80-100°C

notes:
*the setup above results with the following clock rates at maximum demands, thx to Boost 2.0:
core clock: 1306MHz
memory clock: 7712MHz

*while gaming (bf4, cod-ghosts, crysis3) temps are stable around 70-71C
*while gaming @1080p,60hz (bf4, cod-ghosts, crysis3, neverwinter, guildwars2 etc.) fps is between 50-60FPS (very rarely you can see FPS below 50)
*graphic detail setups are set by Nvidia Optimized Profiles, if not, I am setting them manually to the max. details possible

I hope it helps...
Thx, have fun with Lightning Speed! :D

well I didnt have problems switching the bios to LN2. only thing I did is to reinstall the drivers, cause when you switch bios it is like installing a new hardware and you gotta install drivers, thats it.

and also, only the latest beta18 is working. you must update afterburner to b18. there wont be a seperate SE version anymore... they are all integrated into each other...

There shouldn't be any issue switching between the two bios. It's a switch for a reason. You should contact MSI, or whoever you bought it from to see about having it replaced.

Hi, I was looking for help OC'ing my lightning 770. I can't seem to change the Core Voltage as high as your guys, the slider caps out at +12. Trying any overclock causes benchmarks to crash so its no good.

I currently have changed to LN2, using Driver Version 332.21, MSI afterburner 3.0.0 Beta 18 and in settings I have checked Unlock Voltage Control and Unlock Voltage Monitoring. Why can't I change the core voltage higher that +12?

Here is a SS of exactly what I'm looking at when I use MSI afterburner. How do I go further than +12? http://imgur.com/00jGsb7

Might be a little late for you, but i had the same problem when i moved my Lightning card to my 2nd pci-e slot on my motherboard, ln2 bios would not detect at all and gpu-z & afterburner would appear blank. Moved it back to the 1st slot and everything was fine. Was really strange as the normal bios would load on the 2nd slot but not the ln2.

I've tried ln2 bios before and it was not an oc game-changer ! The card still oc the same as if it was on the original bios, but it might become handy when flashing go wrong...
I overclocked my card and it is pretty stable under these settings:
GPU CORE CLOCK: 1320 MHz(boost)-1254MHz(standard boost)
MEM CLOCK:7800MHz
All other settings remained untouched...
I play crysis 3 on max settings with FXAA on and VSync on adaptive and i get 25 min 49 avg 58 max in welcome to the jungle map...
I gess i won a GPU lottery with this one as it does perform good vs 75°C temps and for 280 dollars :D

Hello guys,

I have very strange OVERCLOCK results!! On my gtx 770 Lightning LE card i have 2 bios which need to be physically move(switch) by my hand on Graphis Card! In NORMAL BIOS my OC results is higher and better then on LN2 BIOS!

MSI Afterburner Settings on NORMAL BIOS:

Name: GeForce GTX 770 Lightning LE
Driver Version: 334.89
Core Voltage: +100
Power Limired +109%
Core Clock: +150 Mhz GPU-Z-> GPU CLOCK: 1222; Boost: 1274 ; GPU 2.0 Boost: 1306 Mhz
Memory Clock: +500 Mhz

Picture of ORIGINAL/NORMAL BIOS: http://www.mediafire.com/view/myfiles/#j6zvj9n0u6dhla2




MSI Afterburner settings on LN2 BIOS:
Name: GeForce gtx 770
Driver Version: 334.89
Core Voltage: +12 ( only +12! why so low? )
Power Limited: +109%
Core Clock : +110Mhz ; GPU-Z-> GPU CLOCK: 1182; Boost: 1234 ; GPU 2.0 Boost: 1267 Mhz
Memory Clock: + 500Mhz



Picture of LN2 BIOS: http://www.mediafire.com/view/myfiles/#oq818435y296uj3



With LN2 BIOS we need to have more OVERCLOCK potential or not? For me NORMAL BIOS give me more OVERCLOCK potential than LN2 BIOS. Why is it so? Why is voltage on LN2 BIOS only +12 and on NORMAL BIOS +100?

One more question! When is LN2 BIOS activated, in Afterburner settings must write under graphics card name/model : MSI gtx 770 Lightning LE (LN2) ?

In my case, when is LN2 BIOS activated , in Afterburner settings , name of Graphics Card is just "GeForce gtx 770" . Look my second pictures!

I also have two GTX770 Lightning.
I use the "normal" Bios for overclocking as the lN2 I do not have flashed a GOP Version. (For Windows 8 Fast Boot options etc..)

You write you add +150 MHZ to the core clock , but only reaching 1306Mhz Boost ? Mhhh isn't the Boost on stock already on about 1241 ?

I have reached the following stable setup:

Core Voltage: +65 mV
Memory Voltage +0

Core clock +100 Mhz
Memory clock +300Mhz

Boost clock: 1330 Mhz (Don't know where the 10Mhz disappeared , but that's what it shows....)

With this setting it runs stable in all games I play, including Heaven, Valley or any 3dMark. Mximum tmeperatures, thx to watercooling 51C (It never got more so far). Grafic cards should no longer be air cooled ;)
