@Mr. Fox Fantastic! Thanks for your help. So he doesn't need to buy a new screen to get a dump of a non-corrupt EDID? (Sorry that I'm too busy to read it all through thoroughly and it would just go over my friend's head).

My friend has an M17x R2 with my old GTX 680M in but has managed to fry 3 screens including the RGB LED one by installing recent nvidia drivers! He's sure the EDID has been corrupted. He said he saw there was a way to fix this using linux? Please could someone link me to any info they might have on this. @Mr. Fox?

Perhaps this is a dumb question but did you try to use laptop or desktop nvidia drivers????

Would you consider selling only the 970M? I could send you my 680M so you can still sell the complete system?

Look near the cpu socket on the other side to the socket itself. Sent from my m8 using Tapatalk

Where in the UK are you based? I have a 260M I can send you to test. You need to make certain that it is the GPU and not motherboard or other component.

Best guide is here http://null-bin.blogspot.com.es/2015/08/how-to-modify-nvidia-notebook-driver.html

Pulling the centre pin will not allow your laptop to boot. The two flashing lights you saw were to indicate the system has failed POST due to the video card. You may have soft-bricked your video card. No idea which the BIOS chip is and if you aren't sure either then I wouldn't advise you attempt to replace it. You need a certain competency with soldering to complete such a job. Do you have another graphics card you can try?

You need to mod the inf file in the driver folder. The is a guide on this website that you can search for easy enough.

I've been looking at the X4 also, has there been any coverage on this forum? Sent from my m8 using Tapatalk

The way you solve throttling is to remove the centre pin from the PSU to remove the power limit but this will stop it recharging the battery. Some of us bought more powerful PSUs just to game on with no intention of needing them to charge the battery. You can also buy an L-adapter and remove centre pin on that. What vbios did you try to flash and how did you try to flash it? Were you using atiflash running off a bootable usb? I have a broken 7970M that you might be able to steal the bios chip from if you possess the necessary skill.

Khenglish Any other ideas to improve cooling based on the picture above?

Did you resolve this? I saw you posted this in NBR too and are getting help there.

I'm confused, how is this different to the SKY X9?

Khenglish I tried to put this in a PM but I see you can't receive them so I hope people don't mind me putting this here. Regarding your post above on increasing cooling capacity, I've added some copper vram heatsinks to my heatpipes and have a big 140mm fan blowing air on them which definitely drops temps quite a bit. I wonder if you have any ideas to take this further or how I might add more heatpipes with or without integrated radiator fins to increase cooling on what is quite a limited cooling system in m15x, particularly on CPU side, where fan bracket is integrated into the heatsink. I've checked out Enertron and may buy a few standard heatpipes just for fun (unless you have some spares?) but how do I go about bending them? Thanks!

Thanks! Downloaded and ready to flash!

Stupidly misplaced the vbios editor and all my modded vbios files and download links are dead. Can anyone help me out? I'm after stock clocks and 0.975v undervolt.

Yes! Thanks for asking. I bought a brand new motherboard from China. It arrived in 4 days in perfect condition. Installed it and it works perfectly again. Very happy indeed. Really didn't want to have to buy a new PC. Sent from my m8 using Tapatalk

No, its not even getting that far. It turns on then off after about 0.5 seconds. No indication that it failed POST. Sent from my One using Tapatalk

My m15x froze while playing GTA so now after a hard reset the laptop powers on briefly then powers off, and this cycle repeats until battery and power lead are removed. I've tested PSU, ram, SSD/HDD and so to be, given the nature of how it broke, this seems like a GPU failure. What do people think? Anyone in UK or Europe have a spare old MXM GPU like gtx 260m or gt 240m that I can use to troubleshoot my dying laptop. Thanks Sent from my One using Tapatalk

I don't know what to suggest then. It could be your PSU is dying. I suggest you get a 210W or 240W PSU anyway and it might just fix the problem.

What are your gaming temperatures? Do you know how to use the OSD for temperature monitoring whilst gaming? MSI Afterburner settings > Monitoring > tick GPU temperature and near the bottom tick "show in On-Screen-Display. When you start up the game press F1 I think and it'll display temps. For me the 7970M shuts down at 85 degrees but this is solved by using custom screws to get a tighter fit on the GPU heatsink. I suggest dropping GPU back to stock clocks if temps are high and possibly try to improve thermal paste application and/or heatsink tightness.

You're pushing things too far. Dial back GPU to 850/1300 and CPU to 24x 4 cores, 24x 3 cores, 25x 2 cores and 26x 1 core and see if its more stable. If not then I'd advise PSU upgrade immediately. You might be tripping the PSU by exceeding max output.

Glad to hear flashing 0.975v vBIOS helped. I hope to buy GTA V soon so also glad to hear its working well on 7970M, what graphics settings do you use? For info I run my 7970M at 1.0v and 900/1350Mhz overclock and it works very well. Scores 4856 in Firestrike at those clocks. You can remove the centre pin from 150W but if you plan on overclocking both CPU and GPU then 150W even +/- 15% won't be enough. I use a 210W Dell PSU with centre pin removed and kept my 150W PSU for charging the battery. 240W PSU also works very well and most people buy the right angle adapter so that can also charge the battery.

Can you use software like MSI Afterburner or HWinfo64 to monitor GPU clock speeds? Is the card throttling? If so there is a throttle fix for the M15x (linked in my signature) which involves removing the centre pin from your PSU jack or purchasing a right angle connector and removing the centre pin from that as removing the centre pin stops the PSU charging the battery but does allow overclocking and stops throttling.
