***M18x - NVIDIA SLI (Driver Questions, Performance, Problems) Discussion Thread***

Guys I am getting some serious throttling when i overclock using this this driver 350.05 and also 347.88. I am using m18x r2 with 780m SLI.
i have seen it in battlefield hardline and battlefield 4.
hoping it has nothing to do with my laptop and is just 2 bad drivers.
could Nvidia have crippled the overclocking somehow?

is anyone else having this problem??????

thanks

 

Well, if your cards are overclocking fine with other drivers then it must be a problem with those specific drivers, I can't really tell you from experience as my 980m's are crippled on anything other then 347.90 (on purpose by Nvidia it would seem)

 

I'm also being throttled on my gtx 680m's sli in no limits 2 using oc clock +169, mem clock +500 nvidia driver 350.12 you can see on my screenshot what my cards are actually putting out. Is this normal?

 

350.12 drivers are horrible for 780M... throttling like crazy. [ LINK]

 

Someone knows a Nvidia Inspector SLI config for Project Cars? I'm using the 345.20 driver(780M sli). Thanks.

 

what's the best driver for 780m SLI right now? running m18xR1 780m

currently running 344.75 with little to no issues

i meant ones already modded to run 780m on m18xR1

 

Should be in the thread. Explore.

ok i just put my second 780m in and.....i dont know if everything is working correctly =/ was there any way i could put the SLI cable on backwards? how do i check if the 2nd gpu is working correct?

EDIT: ITS WORKING!!! wow

 

With my 780M SLI any driver beyond 345.20 throttles in 3DMark even with no overclock present. Is there a way to include the newest SLI driver support from 352.86 to 345.20? Playing the Witcher 3 and Project Cars with only one gpu is no fun.

 

My 780M cards throttle really bad with those newer drivers also.

Yup, install the latest driver, export the profiles for the individual games you want using NVIDIA Inspector. Go back to the old driver that works right, then import the profile(s) with NVIDIA Inspector. Or, have someone else using a newer driver export them so you can use them with your older driver. Sometimes this doesn't work 100% perfect, but more often than not I find it to work well.

 

Thanks Mr.Fox I will try it right now.

edit: Used export all driver profiles(NVIDIA Text Format) in 352.86 driver, back to 345.20 and used Import (replaced) all driver profiles no go: Profile(s) could not imported! Maybe they're not compatible with each other.

 

HI,
just updated to Win10.
Rig:
AW M18X with NVidia GTX680M SLI
When SLI activated game performance goes down dramatically.
Does Win 10 have issues with SLI.
SLI Drivers 353.62 Win 10 GeForce Win10 Drivers

Many Thanks
Best regards

No, but NVIDIA drivers have issues with performance and malfunction. Probably their throttle bug has caught up with 680M also. See this: http://forum.notebookreview.com/threads/windows-10.762434/page-181#post-10055473

 

Hi Mr. Fox,
hm I have no overclocked cards (or only as the came from AW). never tempered with clock speeds - still running them at stock speed. Never had any issues. Now since Win10 eg. World of Tanks in SLI has like 15 fps vs. non SLI solid 40-50fps (with Win7 I had 60fps with SLI on)

Is there any work around or do I have to wait for updates on Win10 or Nvidia side.
Am I the only one with this issue??

Many thanks

 

No, that's not it. You cannot even do that with the same driver profiles. It's the screwy Chinese characters in the files that messes things up. It has been this way for over a year. Apparenty, NVIDIA does not want us to have that ability. You need to identify specifically which newer profiles you want and back them up one at a time, then import them one an a time.

 

Ok seems to be a problem not from my system but some games that have issues.
Did some more game testing.
So far issues with
World of Tanks
World of Warships
Wolfenstein

 

hi
i have problem with nvidia driver install.i have a m18x r1 with gtx 780m sli and can't install the drivers under win 10.the installer starts normally but when it comes to installing drivers the screen flashes (like normally) and the install fail.i tried all different things found on the net but no luck on wind 7 everything was ok.. pls help

 

There seems to be some very shifty, goofy and downright sinister stuff going on with Windows 10. The M18xR1 does not have a full-fledged UEFI BIOS (Legacy only, VGA and no GOP support) and Windows 10 seems to want to force the issue with UEFI/GOP.

Do you like living dangerously? I would caution you against using Windows 10 at all. You may end up having to replace your display panel. Windows 10 killed three of mine... two on the M18xR2 and one on my Alienware 18. Please see this thread: Windows 10 Upgrade Warning for Alienware Owners

I would recommend going back to Windows 7 immediately rather than trying to figure out why the drivers will not install. The installation failing may have actually saved you from a disastrous outcome.

 

im now running on build in drivers from Microsoft but i will consider rolling back to win 7

 

I have tried exporting The Witcher 3 Profile from 353.49 (*.nip), however, when I try to import it back to the non throttling 344.75 modded driver using Nvidia inspector, it does not show up in the list of profiles available and the performance is the same

are there any steps I am missing?

 

List of profile in NVIDIA Control Panel or NVIDIA Inspector? If NVIDIA Control Panel, manually add it and choose the game from the recently used list and the profile from NVIDIA Inspector will apply to it.

Witcher 3 is one of the games that may not work well using this method. NVIDIA Gameworks features suck. Be sure you disable all of that performance killer trash. I can see hardly any difference in visual quality with Gameworks features turned on. They impair performance far more than they add value to the graphic experience IMHO.

 

Ok so here are the steps I followed and results:

1. clean installation of 353.49 modded by j95, performance is steady 60fps with a certain predefined graphics settings (Med to High, no Ultra's and performance cripplers)
2. expert profile using nvidia Inspector 1.9.7.3 by Orbmu2k, and saved as Witcher 3.nip
3. DDU back to modded 344.75, testing Witcher 3 with the same settings, 34-38 fps max
4. Added the game from recently used to Control panel
5. Imported the profile in the Inspector

Tested the game, still getting 34-38 fps with no improvement. Also deleting the profile using Nvidia Inspector does not work which is leading me to think that it is not doing anything in reality

 

You are killing #2 when you do 4 and 5. The "expert profile" is getting messed up if you import a stock driver profile for Witcher 3. Stop with #1 and #2 if those give you better results. If you are having issues with 780M SLI throttling using 353.49 drivers, you'll have to decide whether playing The Witcher 3 is more important than GPUs that work correctly. I chose the GPUs over the game and decided not to waste money on The Witcher 3 because having to use crappy drivers so just one game can work well wasn't worth sacrificing everything else. If you're a Witcher franchise addict, that's important. I've never really cared for it and never even finished the first two games, so it was an easy decision for me.

 

I agree that the gpus working properly are more important, and I do not want to sacrifice that for the sake of one game...It is just sad that one cannot enjoy bought games due to incompetence

 

Ahmadmud follow these steps:

- Install latest nvidia driver and install program "Geforce 3D settings Profile Manager"
- Click Export SLI Profiles and save .txt (aka newprofile.txt) you can see in the list the profile for "The Witcher 3"
- Uninstall video driver with DDU and install 345.20 Fox friver Mod
- Install Nvidia Inspector and delete "Witcher 3" profile, add a profile "The Witcher 3", don't forget to add executable in the profile and save
- Install and execute "Geforce 3D settings Profile Manager", Export SLI profiles and save txt again(aka oldprofile.txt)
- Open newprofile.txt and search for "The Witcher 3" profile and copy that piece of text
- Open oldprofile.txt and search for "The Witcher 3" profile and paste overwriting the profile
- Save and exit oldprofile.txt, exit newprofile.txt
-Open "Geforce 3D settings Profile Manager" program and choose Import SLI profiles opening oldprofile.txt

If done correctly now you have SLI working perfectly in The Witcher 3 on 345.20 drivers, and this can be done in all games not just this one. Enjoy.

 

ok im having an issue that is driving me nuts...my cpu and gpu sometimes get stuck at a lower clock rate until restarted, cpu get stuck at 3.9 instead of 4.4 and gpu get stuck at 666mhz core...i have no idea why but its very frustrating...when its not stuck at 666 the gpu runs at 930mhz OC'd just fine

 

Are you using sleep/hibernation, or shutting your system down every day after you are done using it? I recommend never using sleep or hibernation features because both frequently cause malfunction and driver instability. If your machine is always turned of when not in use then I'm not sure why you are seeing that behavior. I've never experienced it before.

 

no i dont use sleep or hybernation...during the game it just gets stuck on 666 then unstuck later stuck again...its weird

i wouldnt even know if i didnt have afterburner stats up

 

Hmm, that is weird it happens while you are actually running it. There may be a simple explanation, but since I've never seen that before I do not know what is causing it. Do you have more than one AC adapter? If so, see if using a different AC adapter changes the behavior. If your temps are fine, it may have something to do with power supply or settings. If you are already using the "High performance" Windows power profile, go into the advanced settings and be sure minimum and maximum values for CPU and GPU are set to full blast settings for AC and battery power in the "High performance" profile. Under CPU it will be 100% min and max, but for graphics cards it will be "Maximum performance" for the power state.

 

i double checked all the power settings, ive been running afterburner stats for a while now and this is something i recently noticed idk if it has something to do with inspector overclocking but i think it began before i OC'd

 

Do you have another AC adapter that you can test with?

 

i do actually , will report back

 

different AC adapter did NOT fix the problem, but it feels like it made it...better?..is this a power shortage issue? id find that unlikely considering the AC block is made to run 2 780s and an OC'd CPU

its highly annoying, the CPU getting stuck at 3.8 or 3.9 is only fixed with a restart which is even more annoying

the CPU issue only happens like once a day though, the GPU getting stuck at 666 happens all the time while playing...idk if its game specific i pretty much only play arma-engine games

 

what do i use to modify voltage on the GPU for overclocking? its greyed out in Nvidia Inspector

could insufficient OC voltage be responsible for me getting stuck at 666mhz?

 

Mod vbios+Evga Precision X16 = You can modify voltage with Evga also.

 

i have this "Nvidia GTX 780m - 'OC edition'" and nvflash...is this what i need to change voltage?

 

You can change the voltage after the flash, using Nvidia Inspector or EVGA_PrecisionX.

I don't know of any software that currently has the ability to mod 780m vbios...

 

Kepler BIOS Tweaker can, but using it is not recommended for most folks. You can really screw things up if you change the wrong settings. Besides, there is no need for it. Just use @svl7 unlocked 780M vBIOS with Precision X or Inspector to change what you want.

 

is there an easier way to flash besides nvflash?

 

Nope... that's the only method available. Besides that, using NVFLASH is super easy.

 

can you throw me a link for the vbios that you use?

im getting my replacement 780m in the mail tomorrow so we'll see how it rolls with the OC on both

 

Sure... the vBIOS is posted here and NVIDIA GPU flashing instructions are posted here.

 

do you think voltage could be the issue with the 666mhz sticking ?

 

vbios update was SUCCESSFUL...time to test

mr fox...my current OC is 940 (+90) core and 2500mhz (stock) memory, what kind of voltage should i use to test if the 666mhz problem is voltage-related?

 

1.012v should be more than enough for 940/1500(3000mhz) with gtx780m. If instability then increase further to 1.018, 1.024, 1.030v only for testing your problem. Use Evga precision X16 for more OC profiles.

 

my memory is 2500mhz (5000) stock

 

Still is 1.012v more than enough .
