Imgur album with GPU-Z/Task Manager screenshots: https://imgur.com/a/OE3bryg I received a GTX1070 card today and am having some issues getting it to be utilized by my laptop (Clevo P157SM). I have installed NVIDIA 417.71 drivers with modified INF file and device manager detects the card as installed with those drivers, Task manager and GPU-Z all detect the card with those drivers as well. However, whenever I try to make my computer use the GPU in any way, my laptop uses the Intel Integrated GPU instead. For example, when I run the render test on GPU-Z, it puts full load on the intel GPU and does not use the GTX1070. Same for when I try to launch a game, it only shows the Intel GPU. The only time I see the GTX1070 have any load is immediately after I open GPU-Z, I can see in the GPU-Z sensors right at the start the GTX1070 clock is 1443MHz but soon it goes back to the idle clock. This GTX1070 is very similar to a GTX1060 I bought which worked fine immediately after I installed the NVIDIA drivers with modified INF file, so I am not sure why this one is having issues. I also tried the same things with NVIDIA 391.35 version drivers to see if older drivers fixed anything, no difference. I have also gone into NVIDIA control panel to force GPU-Z and games to use the NVIDIA GPU, but it still behaves this way. Does anyone know what could fix this? Thank you!

I have a Clevo P157SM with 1.03.04V2 Prema BIOS, i7 4930MX CPU. I am trying to run a MSI GTX1070 MXM card in my system. Initially my EC rejected the card (loud beeps and fans until forced shutdown). Prema made me a custom EC and now there is no EC rejection. However, the GPU is not detected by my system at all (In BIOS, dGPU --> Not detected, in Windows Device Manager nothing at all). Is there any way to mod the BIOS so that the GPU can be installed? Additional nice requests would be the ability to still have unlocked adjustments to the clocks and voltages of my CPU and Memory, and to not have the microcode protection against Spectre and Meltdown.

I have an MSI GTX 1070 card for my Clevo P157SM. BIOS is Prema 1.03.04 v2, BIOS setup says EC is version 1.03.01 (the Prema BIOS files seem to indicate it flashed an EC so this 1.03.01 may be from that folder), Standard 180W power brick. When I insert the new 1070 into my computer, the fans go on full blast and it starts loudly beeping repeatedly. I think this may potentially be resolved if I upgraded the EC. This thread says to never install EC separately to BIOS, and the latest EC it has for P157SM is 1.03.01. Eurocom seems to have some EC files (separate to their BIOS files) for my laptop here: Eurocom Downloads. I wonder if I try to install P15xSM_EC04.zip from the Eurocom downloads whether anything bad will happen to my laptop or if it will fix the issue with the new GPU. In this thread someone managed to install the same card into a similar model (P157SM-A). They say So they apparently never tried it with EC 1.03.01. Does anyone have any tips? Thanks!

I originally thought the vBIOS from techpowerup was a new vBIOS but I realised it was the same version number as what was already on the card. I was suspicious when I had run nvflash -6 "techpowerups vBIOS" and it ran instantly. When I did nvflash with the new one you linked it, it indeed showed a different version number and took some time to transfer some data, it was not instant like before. Hopefully it does not make a difference, but if it matters then I may have messed up. I originally saved the pure stock vBIOS but lost it during one of my fresh reinstalls of Windows. I thought it wouldn't matter since I thought the techpowerup file was identical. Is it possible for the versions to be identical but for the vBIOS to be meaningfully different?

This is the stock vBIOS. clevo980m.rom

No luck Before I installed the drivers, I checked with GPU-Z that the new vBIOS was recognised (it indeed reported vBIOS version 84.04.88.00.C1), but after I installed drivers it reports "Unknown" and 0 values for the memory and clocks. Device Manager also reports the Device Status as "Windows has stopped this device because it has reported problems. (Code 43)". I think this card may be faulty? I don't know what else I can even try.

Thanks for your help and patience Klem. I don't have promotion to download that file but instead I used this: https://www.techpowerup.com/download/nvidia-nvflash-with-certificate-checks-bypassed/ . The vBIOS seems to have flashed successfully. I'm going to try to install the drivers with modded nvcvi.inf and setup.cfg as per the J95 links discussed above. Wish me luck!

When I try to use nvflash with that bios it fails with this message: ------------------------------------------------------------------------------------------------- NVIDIA Firmware Update Utility (Version 5.556.0) Copyright (C) 1993-2019, NVIDIA Corporation.

@Klem Hi, Thanks for your advice. I updated my BIOS to 1.03.05 and tried to install NVIDIA drivers similarly to my attempts above, and the behaviour is unfortunately the same.

I'm using a 230W adaptor so that shouldn't be the issue. I was afraid I'd need those Prema mods... My Clevo is from Metabox which is listed as a Prema partner, but when I email them they say they can't provide me with the Bios. I've tried contacting Prema directly on various forums and on Twitter, offering donations, but still no reply... :((

So after using nvflash to put the Clevo 8gb GTX 980m vBios from techpowerup.com onto the GPU, GPU-Z shows a BIOS version, but still 0 values for the memory and clock speeds on the GPU. Does this seem like I received a faulty GPU, or something that could be resolved by a different BIOS on my mobo and/or vBIOS on the GPU? @duffman_777 - Is the Prema V2 BIOS a BIOS for your mobo, or a vBIOS you put onto the card? I have also heard about maybe needing some special BIOS/vBIOS to install a 980m into a P157SM, but I've also heard some people say it's not required but just helps you overclock etc, so I'm not sure.

I've been downloading the notebook drivers from the official NVIDIA archives and replacing some files according to the J95 page. No matter what I try, after installing drivers and restarting, I open up Device Manager and the GPU is recognised as a GTX 980M but the Device status is reported as "Windows has stopped this device because it has reported problems. (Code 43)". I have tried multiple driver versions, replacing the nvcvi.inf and setup.cfg with J95s, replacing nvcvi.inf, nv_dispi.inf and setup.cfg with J95s (even though the P157SM Optimus 980M shouldn't require nv_dispi.inf to be replaced). I've fresh installed Windows and tried those again. Nothing seems to work If anyone could be so kind, could they package up a set of old NVIDIA drivers with the appropriate files already modified so that I could simply run setup.exe and expect it to work? I have already tried so many permutations but maybe it would just settle the question of whether I'm doing something stupidly incorrect or if the correct instructions simply aren't working on my machine. Is it possible that BIOS and vBIOS or anything like that could be an issue here? I have just the oldest stock BIOS. I've attached GPU-Z screenshots. The one with the card name as "GTX 980M" is after installing 398.36 drivers but rebooting and Device Manager showing the error. The one with "Microsoft Basic Display Adapter" is after running DDU to clean remove the NVIDIA drivers. Both of them show 0 Mhz for the clocks and Unknown BIOS. Not sure if this information is useful.

1. When you download the drivers yourself, do you get the notebook drivers and not the desktop drivers? 2. Ok thanks for clearing that up.

Hey duffman_777, Thanks for the link. I'm trying to give it a go, but I have two questions so far: 1. Under section "Downloads: Standard/Legacy", it gives a link to "GEFORCE 417.71 WIN10" from official NVIDIA servers to download, and then links to "nv_dispi.inf_v417.71_Win10_OPtimus_MSHybrid_AW_ASUS_CLEVO_MSI.zip". The link to the GEFORCE 417.71 drivers is to "417.71-desktop-win10-64bit-international-whql" - i.e., the desktop drivers, not the notebook drivers. Is this known to be okay? 2. Back near the top of the page where the instructions are given, the 3rd point is "Extract driver package using 7-zip … >> Delete Folders as shown above (DON'T SKIP THIS STEP)." I can't see what information above shows which folders I need to delete. Can someone help me out? Thanks! EDIT: In the mean time, I extracted the driver "417.71-desktop-win10-64bit-international-whql" package linked on the page, I copied just the nvcvi.inf file extracted from the linked "nv_dispi.inf_v417.71_Win10_OPtimus_MSHybrid_AW_ASUS_CLEVO_MSI.zip" file. Still the same problems, after install and reboot, device manager still reports Code 43 error for the card

Hi, (You can refer to this album for screenshots: https://imgur.com/a/1UJ2YSj ) I have a P157SM running Windows 10 and had been running my GTX780M with NVIDIA 391.35 drivers running stable long term. I inserted a new GTX980M and started my laptop. Everything seemed to be working fine (I was halfway through a benchmark and it was clearly using the new GPU with higher performance numbers), until suddenly everything froze and I had to reboot. I kept having issues, my laptop would often freeze, so I did a clean install of Windows 10. Since the fresh install: -Device Manager would initially recognise it as "Microsoft Basic Display Adapter" and then automatically install driver 388.xx in the background. I continued to have issues, so I tried to do a regular (no modded infs) install of 391.35, which seemed to install well enough, but after rebooting I would run into errors again. -I downloaded DDU to do clean removes of the NVIDIA drivers and to stop Windows automatically installing 388.xx. I have tried installing 391.35 with modded nvcvi.inf file. Before installing the modded driver I would reboot with the "Disable Driver Signature Check" option, and then I installed the driver. Here are the edited sections of that inf file (the line I added is in bold, I included the whole 13D7 section): [NVIDIA_Devices.NTamd64.10.0...14310] …. %NVIDIA_DEV.13D7.0376.1558% = Section058, PCI\VEN_10DE&DEV_13D7&SUBSYS_03761558 %NVIDIA_DEV.13D7.0870.1558% = Section060, PCI\VEN_10DE&DEV_13D7&SUBSYS_08701558 %NVIDIA_DEV.13D7.5281.1558% = Section062, PCI\VEN_10DE&DEV_13D7&SUBSYS_52811558 %NVIDIA_DEV.13D7.5106.1558% = Section062, PCI\VEN_10DE&DEV_13D7&SUBSYS_51061558 %NVIDIA_DEV.13D7.6540.1558% = Section064, PCI\VEN_10DE&DEV_13D7&SUBSYS_65401558 %NVIDIA_DEV.13D7.6541.1558% = Section066, PCI\VEN_10DE&DEV_13D7&SUBSYS_65411558 %NVIDIA_DEV.13D7.6556.1558% = Section062, PCI\VEN_10DE&DEV_13D7&SUBSYS_65561558 %NVIDIA_DEV.13D7.6780.1558% = Section064, PCI\VEN_10DE&DEV_13D7&SUBSYS_67801558 %NVIDIA_DEV.13D7.6781.1558% = Section066, PCI\VEN_10DE&DEV_13D7&SUBSYS_67811558 %NVIDIA_DEV.13D7.7481.1558% = Section062, PCI\VEN_10DE&DEV_13D7&SUBSYS_74811558 %NVIDIA_DEV.13D7.7500.1558% = Section068, PCI\VEN_10DE&DEV_13D7&SUBSYS_75001558 %NVIDIA_DEV.13D7.7502.1558% = Section070, PCI\VEN_10DE&DEV_13D7&SUBSYS_75021558 %NVIDIA_DEV.13D7.7700.1558% = Section068, PCI\VEN_10DE&DEV_13D7&SUBSYS_77001558 %NVIDIA_DEV.13D7.7702.1558% = Section070, PCI\VEN_10DE&DEV_13D7&SUBSYS_77021558 .....

See picture 2 of the imgur album for what Device Manager reports (and to see that Task Manager does not even recognise the GPU). Picture 4 is one of the blue screens I sometimes get. I have tried reinstalling the drivers (picture 1) with different section numbers but it does not seem to work, I reboot and I still get the same thing as Picture 2. Does anyone know what the root cause of my problems might be? I am open to the possibility that I did not do everything completely properly. For example, I think sometimes when I tried to installed modded inf drivers testing a new section number, when I installed the driver I may have booted Windows without going through the "Disable Driver Signature Check" boot process (however, it seemed like the driver install itself seemed to work fine, although after the reboot I ran into the above described issues). If anyone could point me in the right direction I'd be grateful. Thank you.
