ASUS ROG Zephyrus Duo 15 users prove that lower RTX 3080 TGPs can be maximized via vBIOS flashing with 18% performance gains, but this can affect system stability

[Redaktion]

Modders discovered that the MSI Leopard G76 vBIOS can be flashed on the Asus ROG Zephyrus Duo 15, allowing the RTX 3080 TGP to be raised from 115 W to 150 W. This trick can provide up to 18% increased performance, but it can also lead to serious stability issues like increased cooler noise, thermal throttling and battery problems caused by overwhelmed power supply.

Do you have anything to corroborate these claims of system instability, or is this all just a bunch of opinionated, hypothetical BS?

18% can be pretty noticeable in games if you're on the edge of a performance boundary - it could be the difference between running just over 50fps and getting a solid 60.

I'd like to hear whether this does, in fact, result in any instability or charging issues. They're definitely things that could happen, but are they?

PC gamer article about this says during 3DMark Time Spy test, GPU temperature just averaged to 72° Celsius... So perhaps the Asus Zephyrus can handle the higher TDP

Hello guys, I'm replying this because the person who did the "boosted" version of duo are my friend, we are all users or china's BAIDU forum, so here are the case. The system used Vbios from MSI's GE76, which changed from 115w to 150w GPU. It is NOT stable at all, only used it for the Time spy benchmark was all ready off the limits, the fan speed was hitting 6000+ which should only be around 4500 during performance mode. This Vbios boost you can not use daily, it will damage the laptop. Sad this 18% boost can not be applied to daily usage such as gaming.

I bet that if we could have some kind of 130+15 TGP(instead of 115+15) version of vbios this will be a decent solution, which will increase performance and keep laptops stable.
