Really Sherlock? 980M is officially supported for a year or so 780M/880M users still need to modify drivers.

You need a test mode enabled or it will fail

I modified another driver, if anyone wants it Im sharing. 390.77 - Added compatibility for M18xR1 - GTX 880M. I used section for M18xR2 so there shouldn't be any issues. @NODice You require newer vBIOS as I remember. nvdmi.7z

Sorry I didn't see your reply. Im not online here often. Download new stock drivers and unpack it. Download old stock drivers and unpack it Download modified INF file for your clevo for old drivers from this thread Use something like WinMerge to see differences between these old stock INF files and modified INF for your laptop You will now see which parts are required for your card to be supported Make same changes in new stock drivers INF file and install it.

Okay, it seems I had to do it myself. Attaching modified 388.10 nv_dispi.inf Added compatibility 880M - Alienware M18xR1 048F nv_dispi.zip Driver link - http://international.download.nvidia.com/Windows/388.10/388.10-desktop-notebook-win10-64bit-international.hf.exe Hotfix 388.10 includes kepler fix for Wolfenstein 2

Ah, didn't know. I thought he always used desktop ones. Im using 382.19 right now I tested M18xR1 and still does not work without mod. Ehh stupid Nvidia could just add compatibility INF like they did with 980M.

Yeah and what about 880M and Alienware M18xR1? Im pretty sure it still needs the mod. By the way we are modding desktop drivers, not notebook. Waiting for someone to mod 388.

Thanks. I will wait for some new game until I install new drivers. I install them only if I need SLI profiles for something fresh on the market. Regards

After installing your last driver 385.41 using desktop base on Alienware M18xR1 with two 880M I couldn't use NVENC in OBS. Reverting to old @J95 driver fixed the issue. Also please include driver link in post you upload INFs as @J95 did. That makes life easier.

But which driver to download? Desktop or notebook?

Should we use desktop drivers and replace files as j95 did or notebook drivers?

990M is still likey to be BGA only. No mxm upgrade.

Hey, Becuase of power limits sets in stock bios I've decided to flash SVL7 vbios which has power limits removed. However I get no post, just black screen. Blind flash method is not working as the catrds won't allow me to go through POST. I have unlocked A05 bios. Is there a way to boot using IGFX without dissasembling whole laptop and removing both cards? Regards

Hey, Thanks for the explanation and voltage advices. Yes I have an Alienware M18xR1 with i7-2920XM (ES). I didn't got the cards yet, they're in delivery but im doing everything before so I'll be ready when they come. I've bought two 880M and im doing cooling mod on AMD heatsinks so it'll run even cooler than on NV heatsinks. Have a good day! Regards

Hey, First Big thanks that you even tested it in your laptop. I really appreciate it So basically I have to set base TDP clock to 823,5 then save the bios. Go to boost tab and set max boost to 823,5 then save and it'll result in 823MHz all the time when gaming yeah? Also, will GTX 880M last long on it's default voltage or should I lower it if I want to keep it for 4 years? Regards
