Earlier, Nvidia announced that it is taking a stand against crypto-mining, stating that its new hash rate limiter in its new GPUs, such as the RTX 3060, will stop the miner from exploiting the cards for mining.
However, the recent blunder by Nvidia has revealed that in RTX 3060 GPU miners can use the card for crypto mining by simply bypassing the card’s hash rate limiter simply by using the software.
And according to the latest sources, miners have found additional ways to bypass the GPU / Driver hand-shake to break the hash rate limiter on Ampere GPUs. It all started when NVIDIA accidentally published its GeForce 470.05 driver on its developer webpage that allowed users to bypass the hash rate limiter but later removed it.
But, the damage was done, as soon as the driver was highlighted to enable the full cryptocurrency mining rate of Ampere GPUs, it spread like wildfire and is currently available to download everywhere in public domains.
However, Andreas Schilling of Hardwareluxx has confirmed through his testing that the driver can still restrict the hash rate on the GeForce RTX 3060 when running multiple GPUs. To demonstrate the fact, the GeForce RTX 3060 was run alongside a GeForce RTX 2080 Ti. The hash rate limiter kicks in pretty soon, forcing the ETH rate down to 21-22 MH/s instead of up to 50 MH/s which this card delivers.
One can assume that it is a way of Nvidia blocking cryptocurrency mining when running multiple GPUs. It detects which GPU is being used as a display adapter while simultaneously checking if multiple GPUs are running alongside it. Also, it checks that if mining algorithms are being run on the GPUs.
But this doesn’t mean that miners have not found a way even to bypass this feature. According to Andrea, all you have to do is get dummy HDMI connectors which can trick the driver into thinking that the other cards are also being run for display adapters and allow for full mining rate. So, use the latest trick to get the cards at their full cryptocurrency mining hash rate.
The upcoming card from Nvidia is the NVIDIA GeForce RTX 3080 Ti, but if modders can bypass the RTX 3060, it’s sad to say that the limit will also be bypass on the RTX 3080 Ti too.
