    Hi everybody, special shoutout to triturbo the OG of this thread. this is my first post. I have an 8740 of my own and through the 8740 upgrade guide I managed to upgrade to a 920XM and a 780m(Clevo model). I am experiencing an issue, as triturbo mentioned years ago, the clock speed of the 780m is a fraction of what it should be(192-212 Mhz) and is stuck there. I installed a few different laptop driver versions, changed some bios settings to no avail. I have a 230 watt adapter (HSTNN-LA12) and the 920xm is not being overclocked, I am on Windows 7 Pro I need help

    Also the GPU and CPU that was in before was the FX 2800m and i7 650. I grinded the top of the FX 2800m heatsink where the top left MOSFETs sit on the GPU for the 780m to fit(only place I saw that was blocking a flush fit). Need some help to get this the GPU working properly.(until I buy an 8770w that is )

    Hi there, nice setup! Do you use DDU for uninstalling drivers prior installing new ones?

    Yes I do use DDU everytime. The board is a dual core board. It seems like a hardware issue. Im using the 341.95 drivers from HPs website. I installed the ones from Nvidia using the nvbli.inf. the clock speeds show up as normal(many different WHQL versions and sections in the inf) but the framerates are low(GTX 460 low). only installing direct from the NV_dispi.inf does the true clock speed show that explains the very low framerate.

    As I said im using the 341.95 drivers from HPs website. the true clock speed is showing. Sometimes though the 8740w turns on to a black screen and blinking LEDs from the touch panel(sometimes 3 blinks, sometimes 5 blinks) but a hard reset fixes the issue but thats rare(sometimes it happens after uninstalling the drivers in safemode with DDU). the GPU bios is 80.04.BD.00.05. the laptop bios is F.22

    I just reached @pipkata since he was the one that did the testing. He had the same GPU and used modified drivers, click here to see how to do it.

    Thanks for the link. Unfortunately, J95 is retired, So I cant ask him which line to replace exactly and which takes priority(device model or machine model?). Also This GPU does not exist at all in this Vendors INF, whereas most people on that Guide have Alienwares, Clevos, or ASUS laptops with a different machine models within the INF as a reference with which to replace with their machine model with with the GPU they are upgrading to, whereas the 8740w has only Quadros. but I will try that guide and see if it works.

    I added a new line to the NVBL.inf and a new section as well maybe thats the issue? Also the section numbers themselves denote how the setup installs the drivers but ive found even the same sections within different INFs have different settings.

    You need your PCIe hardware ID. Go to Device manager -> Display Adapters -> Details -> Device Description -> Hardware Ids. It should look something like this:

    PCI\VEN_10DE&DEV_1BA1&SUBSYS_1520103C

    VEN_10DE = nVIDIA
    DEV_1BA1 = GTX 1070
    SUBSYS_1520103C (1520 = 8740w; 103C = HP)

    This is mine, yours would differ at DEV_xxxx.

    So search somewhere in the infs for exactly your DEV_xxxx (780m) and use its sections, while using your Hardware ID string (PCI\VEN_10DE&DEV_xxxx&SUBSYS_1520103C).

    Yeah thats what ive been doing. sometimes the installer freezes at a certain point if I use a certain Section # so I have to hard reset and use another number, but the results have been largely the same when it does install. It seems the core clock speed is not being read/managed properly. I dont even think the 192/212 Mhz is even correct, thats just what is being reported based on the driver. Any driver newer than 360+ reports a clock speed that is in line with what is on the GPUs bios(771 to 849), BUT the framerates remain low regardless. Would a bios conflict be causing the issue? or is this just a software driver issue in Windows?

    How did you manage to get a GTX 1070 to work on an 8740??? I thought GPUs past the 965M didnt work?? thats a serious bottleneck for the 920XM

    Check this guide as well if you can find anything useful.
    You could try to flash different video BIOS. Is there another machine to verify the proper working order of the GPU?

    External only. Can't make it run the internal (DreamColor, the other options are even less compatible).

    Try flashing the K5000m with a DELL vBIOS and try again.

    Try using the K5100m sections for the 780m. Also, you might modify DELL or Clevo inf and see if that would install.
