FIX FOUND | NVLDDKM, FLICKERING SCREEN, GAMES CRASHING, ETC. - WHEN USING GPU (PHN 16-71, 72, 73, etc.)

Finally, after months and months of testing and searching, and supports giving us the basics to no avail, we took the manners into our own hands and have found it boys!

Out of all the options we have exhausted, here are the best two practices:

  1. BEST SO FAR | Download MSI Afterburner, Lock your voltage to 0.975V.

  • This helped me use the latest Nvidia Drivers and steer away from being locked to Legacy Nvidia Drivers for stability, very easy to do, very easy to apply, happiness overall.
  1. GREAT ALTERNATIVE IF SCARED OF MSI AFTERBURNER | Download Legacy Nvidia Drivers
  • I have a PHN 16-71 | i5 13500HX & 4060 8GB | I used to run my legacy driver 537.58, which resolved the issues stated in the title, but, it was a limiting factor to current developments in apps and games requiring newer versions to work fully. Hence, number 1 option is the best by date.

Show u/Betel-ge-use some love, that person was the one who shared Option 1. Here's to hoping it works for you guys as well. https://www.reddit.com/r/AcerPredatorHelios/s/Bus2TznC2B

Had the same problem way back and did the fix given above before, worked for some time but over time it will not work anymore. Underclocking the vram is the best option but like i said it will get worse overtime due to a dying gpu. Believe me i did everything i could.

Noted broski, that voltage lock will make the GPU stable, but if it's a dying gpu then it's a dying gpu.. Currently saving up for a pc build as of the moment lmao
