A Redditor known as Ecstatic_Hamster2208 has successfully bypassed NVIDIA's 140W power limit on the RTX 5070 Ti laptop GPU. Using a Lenovo Legion Pro 5 Gen 10, the user increased the TGP to 160W through VBIOS flashing and voltage curve locking on driver 616.92.
The modification resulted in a 3DMark Steel Nomad score of 4,839, representing a 16 percent performance increase over the fastest RTX 5070 Ti tested by Jarrod’s Tech. While a tool is available on GitHub, the implementation remains strictly driver-dependent.
Users should note that exceeding factory power limits voids warranties and carries significant risks. The tweak may cause miscommunication errors with the embedded controller chip, potentially bricking the machine during the VBIOS flashing process.
