Acer TimelineX 3830/4830/5830 T/G

My P8 and P12 both read 0.83 V, though, not 0.80 V as you mention.

I just flashed the 1.08, and it shows 0.8 for P8 in NVIDIA Inspector, NVAPITest and GPU-Z. Try to validate with the tools from above.

If the reading is still 0.83, what's shown for P0? 0.98V? Does your GPU come with 2GB VRAM?

Yes, 0.98, I guess it didn't take after all. I've only tried flashing under Windows... maybe the DOS flash will make it take? Certainly odd. I flashed back and forth with the official 1.07 & 1.08 and your modded ones and the values don't change with GPU-Z or NVIDIA Inspector, even though the BIOS version string certainly does. But no, just 1GB VRAM here.

There are some more VBIOS files for different models of the GPU in the Acer BIOS and I only modify the one for my GPU. If you would post a GPU-Z screenshot, I could probably figure out which one is yours.

Ah, must have a different ID for my 4830TG. Here's my GPU-Z screenshot

This updated version should work for your system.

I used Acer's chat yesterday and convinced their rep very easily to send me a battery for my 3830tg. I guess they don't know it's internal, will be interesting to see if they'll really ship it.

Any idea on the new bios changes?

Hello,

I am trying to do this Acer TimelineX 3830/4830/5830 T/G , but I was not able to open my laptop. I have 4830tg I removed all the visible screws from the back, but I was not able to remove the panel and I quitted because I was afraid I will break the case. How do I remove the back panel to put the extra metal inside?

Worked great, thank you! Of course as you noted it does nothing for me as far as heat dissipation on my 4830TG, just less voltage used, but still a great mod.
