thảo luận NVIDIA RTX LHR BIOS v2 Unlocker supposedly removes mining hashrate limit from Ampere cards

Is it Game Over for LHR cards?​

The new software supposedly unlocks the full performance of NVIDIA Lite Hash Rate models by modifying BIOS.

The “Nvidia RTX LHR v2 Unlocker” by Sergey is yet unreleased BIOS modification tool that unlocks the mining performance of RTX 30 and Workstation RTX Ampere models. The software has not yet been released and has not been tested. Unlike the existing ‘solutions’ for the LHR mining hashrate cap, this software unlocks the full mining performance as noted by MyDrivers.

The author of the tool claims that the software implements a modification extracted from BIOSes detected by mining operating systems such as HiveOS. This modification is therefore added into the BIOS of cards with limited hash rate performance. RTX Unlocker software supposedly modifies, flashes, and even does a backup of the BIOS. This process is safe and reversible, as the author claims.

Supported RTX Ampere models and their performance

• RTX 3060 LHR V2 – up to 49 MH/s
• RTX 3060 Ti LHR – up to 61 MH/s
• RTX 3070 LHR – up to 57 MH/s
• RTX 3070 Ti – up to 69 MH/s
• RTX 3080 LHR – up to 100 MH/s
• RTX 3080 Ti – up to 115 MH/s
• RTX A2000 – up to 46 MH/s
• RTX A4000 – up to 67 MH/s
• RTX A4500 – not measured
• RTX A5000 – up to 110 MH/s

The software requires a special driver that has to be downloaded from a private server. It goes without saying that even though the author claims that this is an entirely safe process one should mention the exact opposite is true. The use of non-standard BIOS and drivers will most likely mean that those cards cannot be used simultaneously for other purposes, such as gaming, at least not with the most recent game updates.

The LHR hash rate uncapping arrives at a very bad time for miners. The ETH mining is soon to be affected by the Proof of Stake network switch, which will pretty much end Ethereum mining on GPUs. While it will not end other cryptocoin GPU minings, their value is usually highly correlated with ETH performance. Miners need to account for this fact because at some point there might be no return on investment.
