Anyone tried this on the following?

Legion 5-15IMH05H (Lenovo) - Type 81Y6

 

I'm already reaching 77-83c at max load, so a bit skeptical unless its possible to undervolt.

Can you find any vbios for y540 1660 ti which has more than 80w power limit? I was gonna flash desktop 1660 ti bios in laptop but i couldn't find much info on web about it and i dont think its gonna work. I just want to increase power limit, i can handle the thermals. My power brick is rated 230 W.

You can also go to 115W using another BIOS.

I tried this Y540-15IRH on my and successfully change the vbios on my GTX 2060 but it made no change at all to performance. I had an older system bios and tested the latest one and also tried a couple nvidia driver versions. 

 

I ran Heaven and Kombuster benchmarks and power draw is pretty much the same at 81w max on Hwinfo. Even the scores are the same with or without a small overclock. In fact oddly the stock power draw seems a touch higher and same with benchmark results. 

 

Any ideas why it isn't working?

 

Edit: Figured it out. You just need to have Lenovo Vantage installed then update all the gaming add-ons in the software and run it on performance thermal profile. After I made that change my stock vbios power draw went to 85w+ and the new vbios goes up to 97w after a quick heaven benchmark test in windowed mode. 

 

MSI kombuster

stock vbios score 2004

New vbios score 2084

 

Stock vbios with oc score 2095

New vbios with oc score 2242

 

Max GPU temps are around 62-63c after kombuster but will need to run more tests with heaven benchmark and games.

 

My i5 9300h processor has been undervolted by -140mv

 

I'll post more scores as I get them.
