Nvidia 3060 mobile vbios flash

Hello, i have a IdeaPad Gaming 3 15IAH7 with a 3060 and 12500h. My GPU is limited at 105w and currently peaks just over 60c during gaming. I saw that there is a Lenovo Legion 5 15ACH6H that has a 3060 with 130w TDP and now im wondering if it would be possible to increase my TDP? Feel like it wouldnt increase temps that much more and if i would undervolt they would prob be under 70c. Is it possible to flash the vbios from the Legion 5 model? Is it safe? And if it goes bad, can i reflash the stock one by booting into windows using the iGPU? This is my current vbios, and this is the one i have found and would like to try and flash it.
 
I don't think it is a good idea. I don't think they are quite the same part, and the systems are vastly different. Mobile equipment has much less leeway than desktop for cross-flashing and other shenanigans. The performance gains would be negligible at best. Not worth risk. There are an awful lot of "i flashed my laptop gpu vbios and now it is broken" threads...
 
That is risky on a notebook, I would not bother with that, you can brick the whole notebook not just the graphics output. To increase the overall performance and fps drops without risks: upgrade to better RAM sticks (lower latency CL16, dual rank DDR4 3200 modules 2x8GB - on the notebook description it says 16GB is the max ). You can get nice modules second hand. Also make sure that you don't have clogged fans and heatsinks, you don't need thermal throttling on the CPU, that's it.

Ok, so its not worth it. It already has 2x8GB 3200Mhz RAM in it. Would love also if its possible to undervolt the 12500h cause it does pull up to 70-80w sometimes and reaches easily 95c. When i do light gaming ita fine with 20-25w reaching up to 80c. Maybe the TPM7950 (or whatever version lenovo used) isnt applied well on the CPU? Cause the GPU can handle 105w without getting past 80c much.
 
Lenovo uses PTM but it can be that it is not well applied or it was a different paste. I use PTM and undervolting with 8750H so I don't have thermalt throttling, I think you need undervolt only. Using Throttlestop is easy, but I don't know if you can undervolt it. Some new notebooks have locked voltages because it was a security concern with undervolts.

Yeah don't bother with it see my example right here.

Post in thread 'Rtx 3060 laptop no longer working after wrong vbios flash'


If you want to game build a desktop or if game on the go a steamdeck like device.

And trying to increase tdp just increases heat output, louder fans and more demand on the powersupply and battery- quicker burn out of the brick and battery drain, they are not built like the Dell XPS Gen 1 (go look it up)

And no we dont have any files for most mobiles

Yeah its running fine for me, i thought it might be an easy flash without much risk but i dont wanna risk the laptop for like 5fps at most while im getting over 60 constantly.

Man they rly locked everything possible, sad that even undervolting isnt possible lol

There is no such thing as an easy flash, best to just enjoy what you have.

You might consider @unclewebb and his Throttlestop tool
