Predator PH18-71 18" RTX 4080 poor performance how can I fix it, or is hardware problem?

Hi all,

Yesterday I get a new Predator 18" with RTX 4080 graphics card. First thing I did is to select turbo mode in predator sense and run 3d mark time spy test, I get aroud 15.000 points, which is a very low score (I see the normal score in this computer should be between 19K-20K.) Then I selected silence mode and run the test again. I get around 14.900, so almost the same score as turbo mode. There is something wrong here. Nvidia software says 175W so it should run at full speed.

The Specs are:

Model PH18-71

13900HX, RTX 4080, 32GB RAM DDR5, 2TB SSD, 240hz screen.

I´m not an expert. Does it mean there is thermal throttling? Any ideas how can I fix it, or is hardware problem? In other forum I read something about using Display Driver Uninstaller and reinstall nvidia software again...

Thanks

Make sure your new PH18-71 is up to date with Win-11 23H2 and OS build 22631 and all the updates for your laptop.3085, update the bios to its last version 1.16 and install the NVidia GeForce Experience software and update the NVidia RTX4080 drive to its latest game ready driver and use the clean install option to this install, then try the benchmark again, as I don't think that you have setup your laptop fully.

Thanks StevenGen, I discovered one of the problems was the 4080 card didn´t go beyond 90W, I removed nvidia drivers with Display Driver Uninstaller and reinstalled with the latest driver. Now I get full voltage and 19.600 points in time spy graphics. But there is another problem with the CPU temps. The CPU is hot even when is not working. 86 º for only 3% usage for example. It is bad hardware or can I fix this via software?maybe with ThrottleStop?

@Pedro_00 what nvidia mode(auto select or nvidia gpu only mode ) are u running when u took this screenshot ?

Pedro_00

Hi Muhil, I was in nvidia optimus mode, and balanced mode in predator sense.

Muhil

@Pedro_00 this mode u mean?

Pedro_00

Yes, Automatic Select.

Muhil

@Pedro_00 does ur gpu idle outside gaming or not using the dgpu completely?

Have you tried your predator 18 for VR? do you see stutters?

I wonder if you feel warm / hot keyboard under max load?

The temperatures looks normal 57 / 48 (screenshot) , if it went to 86 it means it was doing some work .
Mine looks like this with GPU(on Performance mode) if i use Auto it goes 15-20+ higher .
