MSI 680 Lightning Downclocking

Hey guys - I am hoping someone can help me out with a problem I am having with my 680 lightnings in SLI..
Basically, when playing just about any game, (BF3, FC3, even WoW) the core clock on both cards fluctuates like crazy - along with temps.
I have MSI afterburner going with a simple +100 on the cores (no over voltage) both under water - don't exceed 45C.
I have the on screen display and the core mhz on the cards keeps going from 1293 to under 900, back up to 1200 and down - and keeps doing this whether I am in graphics intensive scenes or not. The temps are also CONSTANTLY fluctuating around 39-45C... constantly moving up and down its really weird. Looking at the actual graphs, it looks like a heartbeat monitor - just without the consistency of one.
I currently have MSI 2.2.3, but the same thing happens with 2.3.0 as well. I have cleaned and reinstalled drivers (multiple ones from beta to current to past ones). Only thing I haven't done is reinstalled W7, though I don't know that going that route is going to change anything. I have tested both cards by themselves and they work great without any problems - I can actually OC them to around 1390 individually with some voltage added full stable, but when in SLI, nothing I have done seems to stop this constant fluctuation and no matter how much voltage I give them, I cannot get past a simple +100 on the core (to like 1293). This fluctuation is what I think is causing alot of the recent crashes I have experienced in game - where as I had none before.
The only thing I have done differently is that I recently switched to a Silverstone Raven 02 case. Any ideas? I have bios 80.04.09.00.F8 on both cards.
Below are my specs:
2500k @ 4.5
Maximus V Formula
8gb Corsair @ 1866mhz
SeaSonic X 850w psu
--originally posted on Overclock.net official msi gtx680 lightning owners club post #4545-- It looks like others are having these issues.

Thanks for the reply on this!
Yes, my power limit is set to max and I am under Maximum Performance in power management along with single monitor performance (no multi for me just yet).
I really don't know what it is that is causing this. If I go down to simply +100 oc, with no over voltage, I play everything pretty smoothly without much trouble, except for the CONSTANT downclocking and temp changes. Everything stays relatively smooth. I don't know why they only OC to this when in SLI, but get much much more individually - drives me nuts.

MSI 680 Lightning fan noise

So, one of my 680 lightning fan is making noises. It's coming from the fan, because when the noise starts i stopped the fan with my finger and the noise stopped.
Its not a cricket noise, its more of a whining noise, like the inside of the fan hasn't anymore grease in it, to oil the movement parts.
I will buy some special oil for electronic devices or some silicon grease to oil back the noisy fan.
But im asking, i can open the 680 lightning's fan, to oil it ? Or it's all sealed up ?
Someone if could answer, because i dont want to end up myself not able to open the fan and broke something.

Yeah, the GPU temp is unreal. It never wants to go above 58 degrees. With stock like said i was having 72-75
Only vrm's are a little downside, with +5-6 degrees like on stock msi cooler. This cooler is damn good, think i will keep it maybe it will work on maxwell cards too
And the fans are pure awesome, 100% speed and no sound...
Problem is they don't blow air with force like the MSI fans did.

MSI 680 Lightning high temps

Just got the card and it idles at 60-65 and the sec I run anything intensive temps rise until it shuts down.
The sec i run a game temps will spike and shutdown. Before I request a RMA, would it void the warranty if i reapply TIM to the card to see if that helps?

Yes, you can try this. If you don't broke anything during procedure the warranty will be fine.
But you also can contact reseller 1st and notice him, and to ask for such permission.
Else if theire no improvment he may said that this is hapends because you messed with it

MSI GTX 680 Lightning compatibility with Windows 64/ Asus P6T Deluxe MB

I purchased a GTX 680 Lightning on Dec. 16. I've been having random PC lockups and Driver hangs/restarts. Here's what I have done so far to try and remedy the problem:
-started with MSI Afterburner version 2.2.5 BETA and Nvidia ( MSI provided ) drivers 301.42, and standard bios .
-upgraded to various newer versions of NVidia drivers, BETA and WHQL. Usually the newer drivers become even more unstable.
-Upgraded to Afterburner 2.3
-I had the original bios versions first shipped with the card, I have since updated the BIOS:
from 80.04.09.00.F7 --> 80.04.28.00.39
from 80.04.09.00.F8 --> 80.04.28.00.3A ( LN2 )
-NVidia control panel settings left at default, with Global/all profiles set to "prefer maximum performance".
-I originally had a GTX295 installed, so all drivers etc. were fully removed, followed by clean install of 301.40
-Afterburner 2.3.0 is installed, Core voltage is set to +12mv, and the power limit is set to 178%
-memtest run for hours on my memory, zero faults.
-furmark run for hours, no crashes
-3dmark run repeatedly with varying overclock settings in Afterburner, no crashes
The updated LN2 BIOS seems to be sllightly more stable, but I still see random crashes when running Windows media player, VLC Player, Internet Explorer. Its definately a problem between windows multimedia and the Nvidia drivers. I can play Skyrim maxxed out, for hours, yet when I first login to the computer and run IE, it sometimes locks up.
I've had the driver stop and recover while Afterburner is monitoring on-screen, and sometimes the CPU load will spike to 100% at the crash, yet sometimes it does not. GPU power voltage always sits at 0.987 or 1.212V. matching the power spec expected for the LN2 BIOS.
I've had GPU-Z cause at least 1 lockup, with the screen blanking red. Only 1.
My next step will be to try updated drivers again, now that the bios has been updated. I may also downgrade Afterburner to 2.2.5 BETA.
Does anyone have any other recommendations I can try? Can someone point me to the latest BIOS version for the card ( or can i try that hybrid BIOS now available? )
At what point do I give up and RMA the card?
Card S/N is 602-V283-02SB1206030939
Windows 7 Professional 64
Corsair 12GB mem, matched sticks
69 GB SSD for the OS, a Raptor 320GB disk for the rest
Antec True Power Quattro 1000W power supply
Asus P6T Deluxe MB ( not v2 )
Intel I7 cpu 2.93 Ghz

I'm going on 3 days of stable performance. I made 2 changes:
1) core voltage in MSI afterburner upped to +87mV, power limit at 150%.
2) I have an ASUS P6T Deluxe motherboard, and am running the UPU-6 engine. This utility is designed to let the motherboard auto-switch from max power savings -> medium power savings -> max performance ( 100% CPU ) -> turbo mode (O/C CPU ). I had this set on Auto, and I have re-set it manually to max-performance.
I think the EPU-6 engine was the problem, I am waiting for a few more days stability to prove the theory.
EUP-6 will lower your clock speed when idling, and then bump up your performance when you start doing things. In my case I would go from playing a game ( Skyrim) to running IE, and EPU-6 would change modes DOWN. In reverse, I would be doing nothing. then run IE or media player, and EPU-6 would change modes UP. Those state changes are where I think I was getting blackscreens and lockups.
I still don't understand it exactly, I think the combination of my MB changing power/performance AND the GTX680 also changing performce creates some kind of conflict. I have had the Afterburner graph going when the driver crashed, and it shows the GPU power maxing out when the driver crashed. All other graphs bottom out ie. the whole card "hiccups".
So I will put the core voltage back to defaults, and also set the Nvidia display/performance options all back to defaults, and keep the EPUJ-6 engine stuck on max-performance, which is basically leaving the MB running at 100% stock CPU and power. I expect that will prove stable and resolve the problem.
Crossing my fingers.

MSI GTX 680 Lightning - No Signal/100% Fans

Hi, I recently built a computer, which contains an MSI GTX 680 Lightning. This is the first time I've built a computer so don't kill me if this has a simple solution.
The computer ran fine for a few months, then all the sudden I started getting a recurring issue where both my moniters show "No signal" and the 680's fans turn up to 100%, it stays like that and I have to reset the computer, after which it seems to run fine for a while and then it happens again unexpectedly.
The issue seems to happen more frequently when I'm playing games, but it also happens when I'm not even at the computer. Also, I haven't updated any drivers or anything recently so I don't think it would be that. This is pretty annoying, so any help would be appreciated.
~Thanks.

MSI Mpower Z77 w/MSI NGTX 680 Lightning

Got started on my first ever PC and I'm stuck, so please bear with me. The parts that I have are the MSI Mpower Z77 and the MSI NGTX 680 Lightning (video card). There are two 8-pin connectors on the video card which needs to be plugged in. However, reading the user guide for Mpower Z77, it mentioned an ATX 6-pin power connector on its main board. It's designated as JPWR3 (p. 1-15) and it's suppose to provide power to the graphics card. My question is, do I need to plug in the JPWR3 on the main board if I'm already connecting two 8-pin power source into the video card?
I'm pretty confused about this because I've heard varying accounts. Speaking to people, they've said that the JPWR3 not only powers the graphics card but also all the PCIe expansion slots. Don't know how true this is since there's no mention in the user guide. On the other hand, I've had some people tell me not to bother with it if I'm only using one video card; they've stated while it doesn't hurt to have JPWR3 plugged in, it won't do anything unless I'm overclocking or running SLI/Crossfire, in which case I'll be drawing lots of power.
So what to do? I am tempted by SLI...but that's a bridge I won't cross until next year. So in the meantime, should I plug in JPWR3? Any pros and cons either way? It'd be great to have some feedback or consensus. Thanks.
Oh, and if plugging JPWR3, do I use the PCIe power cable from the PSU??? It's the only 6-pin I have left.

its better to connect all the power connectors anyway to avoid problems later on in time if he upgrades! also if the PSU you have isn't capable of supplying that big an ammount of power to the board the optional header will fill in the missing shortage and your less ikely to have noposts as the graphics cards power from the slot is choked so its more just safety!
most experianced builders will say even if its not needed connect it anyway to avid problems with your build....
let me put it like this its better to have it connected and its doing nothing then to try and boot a machine and it needing it but its not connected and as a result the machine doesn't post!
the PCI power connector on the board will be active only if needed and connecting it won't cause any problems but work as a boost if needed!

MOVED: msi gtx 680 lightning unlock

This topic has been moved to BETA & MOD BIOS Section.
https://forum-en.msi.com/index.php?topic=164556.0

Hi, i tried too the modded LN2 BIOS and i have experienced very strange behavior:
After flashing the LN2 BIOS with this one (80.04.47.00.42) and rebooting - the PC did not start, there was no signal to the monitor (the two DVI ports were not working), only through the HDMI (connected with a TV) i saw that the motherboard was reporting some kind of an error and was asking to make a choice - F11, F12 ... but whatever i was choosing there was no reaction. The keyboard was operational, it seemed that the motherboard BIOS was freezed. I tried hard restart -> same situation. Then i changed to the default bios (80.04.47.00.18) and the PC booted and seemed to work normal. Ok, i tried once again the modded bios (80.04.47.00.42) -> the same behavior (BIOS crash). Somehow (i do not know exactly how) i succeeded to boot Windows with 80.04.47.00.42 and everything seems fine. But when i play games for a long time (for an hour for example) suddenly the game freezes and the cpu usage raises near 100%, the whole PC hangs and only hard restart fixes the problem. The problem repeats randomly with and without GPU overclock.
My PC configuration is Biostar TZ77XE4,I7-3770K@[email protected],Prolimatech Megahalems Rev.C,2x8GB DDR3 2133Mhz GEIL EVO LEGGER ,SSD OCZ Vertex 4 256GB SATA3;Seagate 500GB,WD Black 640GB,MSI N680GTX Lightning@1359/7600,Creative 24bit,Cooler Master HAF X,Chieftec CFT-750-14CS, 22' TFT Benq 1920*1080
I think that the problem is between the motherboard BIOS and the GPU BIOS, but i cannot explain it to myself - why? The motherboard bios is the latest stable (Z77CF419.BST). Now i am with the unlocked 80.04.28.00.3A LN2 bios and everything is working fine with and without GPU overclock.

MSI GTX 680 LIGHTNING having MSAA ANTI ALIASING ISSUE

Hey guys!
I have a question concerning my GPU. I would like to know if anyone thinks this is a faulty card or is there something I need to do to fix the issue.
MSAA Anti-Aliasing is causing a very weird blood graphic issue... Toggle it off and the blood looks fine, turn it too 2,4 or 8 and the blood is outlines in glowing yellow craziness(see image link below)!
My card is stock and has never been OC. I've re installed the game, done clean installs of GPU drivers but the error still persists(only if MSAA Anti Aliasing is enabled). Prior to installing new drivers I was getting a OPEN GL error 3 code , the new drivers seem to have fixed that.
This is zoomed in using a camera, it looks the same at all distances. The yellow trace around the blood shines like a light in game. This does not happen randomly, all blood splatter in the grass looks this way when
MSAA Anti-Aliasing is enabled.
Hope someone can help!
Thanks for reading,
cheers!

MSI N770 Lightning.. The Lightning Continues...

From MSI N680GTX Lightning to the R7970 Lightning, now comes the new N770 Lightning.
First of all let’s talk about the GTX 770 GPU Chip. It has the same GK104 graphics processor as the GTX 680 have but cranked up. Reference core and boost clocks have been raised to 1046MHz/1085Mhz and the memory speed to 7GT/s. Aside from this, the GTX 770 GPU Boost has been upgraded to version 2.0, allowing Higher Clocks to punch in more often.
Comparing: GTX 770 vs GTX 680
Stream Processor:1536 - 1536
Texture Units:128 - 128
ROPs :32 - 32
Core Clock:1046Mhz - 1006MHz
Boost Clock:1085Mhz - 1058MHz
Memory Clock: 7Ghz GDDR5 - 6Ghz GDDR5
Memory Bus Width: 256 Bit - 256 Bit
TDP:230W - 195W
Transistor Count: 3.5B - 3.5B
Mftg. Process: 28nm - 28nm
Now with the N770 Lightning, the video card has been factory overclocked to a core speed of 1150 Mhz (ref. 1046) and a boost clock of 1202 Mhz (ref. 1085) while the memory clock has been kept on a standard speed of 7010 Mhz. The GTX 770 Lightning will also use MSI’s GPU Reactor providing higher power levels and cleaner signals for the GPU. Other components that MSI have integrated into the card are the Military Class IV, voltage check points and 8+8pin PCIE Power connector thus making the video card break limits in the world of overclocking.
Here are the things you will find upon flipping the front cover of the box…
For the accessories…
•Certificate of Quality & Stability
•Quick User’s Guide
•Driver Utility Disc
•SLI Bridge Connector
•V-Check Point Connectors (connecting this with your digital multi-meter will show the actual voltages of certain components of the video card like the GPU)
•2x 6 Pin to 8 Pin Power Connectors
•DVI to VGA Adapter
With the Lightning’s TwinFrozr 4 cooler, it promises to bring the video card temps below 60c and at the same time being quiet. It also boast the 2x 10cm Propeller Blade Fan technology which provides higher air volume to the card for faster heat dissipation. Dust Removal technology is also been implemented now in the Lightning series of video cards as it automatically cleans your video card.
Two SLI bridges on top of the N770 Lightning and to clarify things up, it is only intended for a Tri-SLI configuration.
Below are three SuperPipes with one being on top which also helps cooling the GPU chip. You can also see at the bottom part of the video card the Golden SSC Military Class IV Components.. These components are no ordinary; they can withstand extreme conditions, run with stability and power efficiency and provides longer lifespan to the video card.
Checking the back side of the card, back-plate is installed thus making it cooler and to avoid bending the video card. The blue circle thing you see there is the GPU-Reactor – an additional PCB connected at the back of the video card which also lights up when powered up.
Video Outputs:
•Dual-link DVI-I x 1
•Dual-link DVI-D x 1
•DisplayPort x 1 (version 1.2)
•HDMI x 1 (version 1.4a)
My Test System:
•Processor: Intel i7 3770K
•Motherboard: MSI Z77 MPower
•Memory: G. Skill Pi Black 2x2GB 2200Mhz
•SSD: Kingston HyperX 3k 90GB
•PSU: Antec TPQ 1200
First set of benchmarks are all on Stock Speed.
1. 3dMark06 29765
2. 3dMark Vantage P34525
3. 3dMark11 P10759
4. Heaven DX11 X 2341.411
2nd Set of benchmarks, all were overclocked. From the Processor, Memory and as well as the Video Card. You can also see that the video card would perform better on an overclocked Processor.
1. 3dMark06 38407
2. 3dmark Vantage P39691
3. 3dmark11 P12356
4. Heaven DX11 X 2477.77
That would be it

Hello,
About PSU: 450W is not enough for either of them. For 760 or above it is recommended to have 600W (as the minimum) power supply.
Both cards has similar cooling, but I would prefer lightning edition (hey, it's 770 not 760 which is little bit lower in performance). However if you also look for the design to fit your case, then that's up to you. Obviously if the card will run hot, most likely you will have to reapply thermal paste (very common in case of GPUs).
Your shop is very limited, but why not use this search, just pick your country Already selected for N770 lightning

GTX 680 Lightning very slow

Hello there,
I'm stuck with the installation of the graphic card MSI GTX 680 Lightning, which is very, very slow. For sake of comparison, it does not score even 9000 in 3D Mark, while my previous Radeon 5770 reached 17000 without any problem.
I tried several actions:
Remove drivers with drive sweeper under safe mode.
Installed updated drivers.
Reinstalled Win 7 64 bits
None of that make any difference. If I return to the previous card, the system works well again.
My PC is:
Processor: Intel Quad Core i7-960 (chipset Intel X58 (Tylersburg 36S) + ICH10R)
Mobo: XFX MB-X58I-CH19
Memory: 12 GB (Kingston 4096 MB PC3-10600 DDR3 SDRAM triple channel)
HDs: SATA 3 Gb/s SAMSUNG HD321KJ and SATA 6 Gb/s ST2000DL003-9VT166
PSU: Corsair TX850
Operational System: Windows 7 64 bits Ultimate
Graphic card: MSI N680GTX Lightning 2 GB GDDR5 PCI-E 3
Does anybody have any idea on what should I do to make it work?
Could it be some incompatibility with my mobo?
Best regards,
Antonio Intini

What does gpuz say? (Can you post a screen shot)
Have you installed Afterburner? Is it throttling or anything when using kombuster?
Can you upload a copy of your vbios somewhere for svet to take a look?
<<<NVFLASH>>>
with syntax from cmd:
nvflash -b myrom.rom [ENTER]
then upload myrom.rom somewhere and give a link to it
Are you using the newest applicable bios for your mobo? (Since the booting is an issue this may be easy)
**EDIT: I have been having issue with LUCID MVP since I installed my 680 (not lightning though) I am not sure if that mobo is equiped, might want to try uninstalling if it is and see if it is better.
Hello Xmad,
I updated my BIOS today with the latest file from XFX. Good news: the processor speed is now OK, though SM2 and SM3 in 3dMark are still bad:
Overall score: 11715 (target 19200, but it was not above 8000 before the BIOS update)
SM2 score: 3791 (target 7300)
SM3 score: 5530 (target 10000)
CPU score: 4836 (target 4700) -> great!
I tried to use NVFlash, but it does not run in Win 7 64bits - do you have a version for 64 bits?
Apparently the graphic card works well with Kombustor benchmarkings:

What version Afterburner have you been using?
Perhaps you should also check with the Afterburner support forum.

sigh they allways give the same boring response...im not stupid ofcourse iv got the latest drivers feel pretty ripped off by msi atm u cant release a product without the software..... its false advertising.......box say supports tripple overvoltage......but it doesnt yay......
I am the moderator at the MSI "User to User" forum that gave that reply to him. I am a user of MSI products as are all of the mods over there and none of us are paid by nor employed by MSI. MSI does not write the code for Afterburner as you all should know and for him to come here bashing MSI & their support forum is uncalled for. I respectfully request that this MSI bashing post of his be removed as well as my reply.

MSI 6970 Lightning - artifacts issue

Hello,
Yesterday I received my MSI 6970 Lightning and today I installed a few games to try and see how it performs.
Everything works as expected until you start stressing it with some of the newer, heavier games and/or benchmarks.
I took some pictures to show what I mean that you can view at:
http://dev.nixit.nl/artifacts/
It's running at default speeds and I tried the latest drivers from MSI as well as the latest official AMD/ATI drivers and v12.1
Other information that may be relevant:
motherboard: evga x58 sli
PSU: 1000w cooler master
ram: 12gb ocz ddr3 1600
hdds: 2x74gb raptors (heh, oldies I know), 2x750
Any ideas? I mean, I know that I can probably downclock it but come on it should run at its advertised speeds at least, right?
Is this a known issue? If any other information is required to solve this please do ask I'll be here checking for updates!
Thanks in advance

You should read this thread and specifically regarding the switches on the back of the card. https://forum-en.msi.com/index.php?topic=150708.0
These are the switches that should ONLY be operated by professional overclockers under controlled circumstances.
Mainly because these switches remove precautionary measures from graphics cards to allow them to deliver the highest levels of performance.
These switches can be found on the back and the side of the card and have several functions:
Quote
BIOS Switch, run with the normal Lightning BIOS or a special sub-zero version
Please check this switch, i.e. the position its in. Ensure that it is in the "Normal position".
Then the following switches are best left alone, but just check.
Quote
Xtreme Cool :
Removes coldbug (boot at sub-zero temperatures!) on N580GTX Lightning
Increases the AMD Powertune limit by 250% on R6970 Lightning
