Windows 10 - P151SM - Video Card stuck in P-state P8

I hate to post this as I am guessing this is some sort of driver issue. I've gone through all of this forums (along with the rest of the web) trying to solve this. Nevertheless, I am struggling with my P151SM and its 870m. Info below:

Windows 10 Home 64 - Recent Upgrade
870m - Gefore 359.06 WHQL Drivers (stock bios, 80.04.F8.02.06)
Intel 4600 Graphics - Drivers 15.40.04.2

The card will not move out of P-state P8, gpu clock stuck at 34Mhz, memory clock 324Mhz. VDDC at 0.818v. When I load up a game or program the GPU usage shows it is using the 870m and its GPU usage in nvidiainspector goes up to 99%, but the all the clock rates remain at their base level.

I have tried disabling all the components and uninstalling/reinstalling all the drivers. Also going through Nvidia control panel to change the power mode out of adaptive. I am assuming this is a driver issue but for the life of me I cannot seem to figure it out. I'm guessing it is going to be a simple fix, something that I have glanced over.

Anyone else have/solved this experience? Thanks in advance.

 

Uninstall your Intel and NVIDIA GPU drivers and make sure to run DDU, then install the latest NVIDIA and Intel GPU drivers and maybe even the latest Intel chipset drivers (before the GPU drivers). If that doesn't help, then maybe you should see if someone can make you a custom vBIOS for that card and see if that helps.

 

Sorry to Rehash this one but no solutions have come up yet.

From what I have read it appears to be that the GPU is stuck in battery saving mode, as mentioned on a couple other boards:

https://na.alienwarearena.com/forum...-1/alienware-15-graphic-issue-very-low-3dmark

Not the same cards, but the same symptoms. I have gone through all their solutions but I still no success. I have also tried removing the main battery and Cmos battery. I have flashed a new Vbios on the card and even that has not rectified the problem.

Anyone else have any experience with these issues or am I on the hunt for a new card?

Thanks in advance,

Go into NVIDIA control panel and change from adaptive power management mode to prefer maximum performance power management mode. See if that helps.

 

Unfortunately I have tried that as well.

Interestingly, when connected to a secondary monitor the GPU memory clock goes up to ~1250Mhz but the Core Clock remains stuck at the lower values. When just using the built in LCD the memory clock stays stuck at 162Mhz.

Thanks for all the help. I might try pulling the card this afternoon and booting without it to see if that changes anything.

 

As far as I know, you wouldn't be able to boot with the MXM GPU removed.

 

I would try taking an image and see if a fresh OS install returns it to normal.

 

Here is one new oddity that is taking place - confirming that there is something to do with power involved. If I have a 3D application running the clocks and voltage remain low (0.818v, 33.8mhz 162 mhz). But if I unplug the machine briefly the memory clock goes up to 1002.4 mhz, gpu clock remains the same. There is a blip on GPU-z which shows the gpu clock going up to 966.8 but only for a second.

After all this 'plug unplug' nvidia inspector shows the Pstate as P1 and the memory clocks will go up to 1002.4 and back down. Just a gigantic mess pretty much unfortunately.

I'll do a clean install in a few days and see how that goes. Hopefully all will work out, thanks again for the help.

 

How did the clean install work out?

I'm currently facing the same problem. I've narrowed it down to this exact error where it's stuck at 34MHz.
