@svl7, could you please share the unlocked A13 BIOS for the Alienware M17x R4 if you have it or please otherwise unlock it and share it with us? I would be really grateful if you could do so as there are plenty of people like me with A13 who would love to have full compatibility with Windows 8.1 which A11 doesn't have.. it would also make it less risky for us to flash an unlocked BIOS as we wouldn't have to downgrade etc. I'm quite sure we'lll all be happy to donate a beer or 2...

How is boost good? 1st thing I did once I got my 970M was to flash svl7's VBIOS to disable it... It messes up your clocks.. I run at full boost clocks now all the time during gaming and performance is much better.. Not to mention svl7's vBIOS lowers voltage to 0.95 and my card runs rock stable and cool..

You can use a 980M in a P370EM.. All you need to do is flash Prema's modded Bios and EC from his website... This has to be done with your 680Ms inserted... Then you can replace them with 980Ms, install driver and flash either Prema's or svl7 modded 980M vBIOS...

I was referring to 347.88... Haven't tried 347.90... Can u make a mod for 347.90 for Optimus mode plz?

Oh definetly! My benchmark scores have gone up and I can probably OC even more if it's not for my PSU tripping!!

Yeah will try this tomorrow... Earlier when computer crashed, GPU drivers got disabled... Dude this one better work properly

Yup using Optimus... The one in the above link worked perfectly!

@J95, your mod in this thread worked perfectly for me.. 347.88 installed and working perfectly for me! http://forum.techinferno.com/alienware/8113-going-test-clevo-980m-alienware-m17x-r4-m18x-r2-aw17-146.html#post127079

J95. First inf doesn't give optons to install HD audio, 3D, Mircast.. Second one allows this but driver doesn't install...

Why do we need to install 2 times?

Hi J95, Thanks for remembering about us.. I have downloaded the driver and installing it now.

@J95 how can you boot with Windows 7 and 980M? Does it work properly??? You haven't answered my question from earlier.. Thanks, Tom - - - Updated - - - @J95 how can you boot with Windows 7 and 980M? Does it work properly??? You haven't answered my question from earlier.. Thanks, Tom

Can someone with a Alienware M17x R4 confirm the following? When you switch between Optimus and dedicated modes, have u had to reinstall NVIDIA drivers? Also, I heard that windows 7 works in Optimus mode supposedly in this Alienware upgrade thread.. I might have read wrong but do correct me here if it isn't the case.

Agreed.. We need an unlocked A13 BIOS to have Windows 8.1 support.. @svl7, quite a few people have been asking for it.. Please do give it a shot if you get some time and I'll be happy to send some cash for a beer

Did u use nodded inf file which laptopvideo2go provide? Otherwise driver won't install.. If that file doesn't work, @J95 has provided molded inf.. Have a look around..

J95 you have the 980m in the R4 right? When you switch between Optimus and dedicated modes, have u had to reinstall NVIDIA drivers? Also, I heard that windows 7 works in Optimus mode supposedly in the Alienware upgrade thread.. I might have read wrong but do correct me here if it isn't the case.

Max OC with Core on 1438MHz and Memory at 1543MHz with 344.75: NVIDIA GeForce GTX 970M video card benchmark result - Intel Core i7-3940XM,Alienware M17xR4 Max OC with Core on 1438MHz and Memory at 1553MHz with J95 modded 347.52: NVIDIA GeForce GTX 970M video card benchmark result - Intel Core i7-3940XM,Alienware M17xR4 About a 200 increase in FS GPU score... Mostly due to the newer driver.. Also OC was more stable.. My PSU was tripping in FS GPU Test 2 so I probably need to get a new PSU

Yes it should work with all NVIDIA mobile GPUs..

Well I'm not telling him to deliver it now... What I want to know is he doing something about it.. I don't mind waitng.. I just want to know if he's doing anything!

Prema, have you had a look this file and tried anything? A lot of people were expecting you to be able to come up with a fix

So clearly the problem is in this nvlddkm.sys file.... So for people focusing on finding what to fix, this is the file that needs to be compared.. Gonna try a bench and see if it's better with this driver compared to 344.91

What if you don't delete any folders? I've kept everything but GeForce Experience doesn't work.. Honestly, that's a massive no no.. Does GeForce experience work when you delete them like you did for you? Edit: I had to uninstall and reinstall it.. Works now Edit2: @J95, in NVIDIA Control pannel and GeForce Experience, it shows that I have 346.87 installed.. Only the GPU-Z shows 347.52... Is this what you get too?

@svl7, @Prema, maybe you guys can have a look at the newest drivers and spend some time figuring out if anything can be done? I'll be happy to donate if some modded drivers can be made..

I'm going to say this again for all those who can't read my thread or haven't read any of my posts... The 970M/980M don't throttle in Optimus mode in M17x R4 and AW17 !!!!!! Stop whining your heads off and just use your NVIDIA GPU in Optimus mode! You can OC and do everything with unlocked vBIOS + EVGA Precision X!! Also can someone tell me what display port version is the one in the m17x R4 or the M18x R2? Will it run 4k@ 60Hz??

Talon my max OC was about +300 core and +600 memory.. Voltage was 1.065V (I'm running max boost clocks on 0.95V) so I need to push voltage more for bigger OC.. I don't want to brick card and have no time to bench so this is the best for now..
