The Official MSI GTX 770 Lightning Thread
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. :)

I have a problem with MSI GTX 770 lightning edition that i can't get more than +60 v on the core clock with max core voltage is set to 100, i use the afterburner version 4.0.0 (final/stable), i keep crashing in Heaven benchmark when i set my core clock +60 v.
my settings in the afterburner is (LN2 bios):

Core voltage 100 mV
Memory voltage 100 mV
aux voltage 50 mV
Power limit 109% (prioritized)
Temperature limit 95 C
Core clock 50 MHZ
Memory clock 300 MHZ

And what about the Fur mark benchmark, it's one of a hell benchmark that push your GPU to its max temperatures , i really would like to hear about your test in fur mark.

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 ;)

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'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

Where are you guys getting your memory clock numbers from? Even at +375 MHz Afterburner is showing me at 3881 MHz.

Yeah.my Ln2 bios wont display anything on the screen


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 have a question.Does ur 770 lightning came with a fully working Ln2 bios?when i switch mine to ln2 the pc will just open but it wont display any on the screen.is my Ln2 bios broken?pls help me Add me on facebook

https://www.facebook.com/john.neal.5872


thanks in advance



it still wont work.i switch it to ln2 then like 5 mins later the Monitor is still Pitch black.

i wanna use ln2 cause Afterburner Wont make a beta version that support +100mv in afterburner.Se version


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...

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

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.
