Ever since the RTX 3060 launched, hackers have been trying their best to bypass the Hash limiter NVIDIA has enforced on the card which limits the card’s mining capabilities. And in the latest try, miners have found additional ways to bypass the Hash Rate limiter for Nvidia RTX 3060 using dummy HDMI adapters.
Last week, NVIDIA accidentally leaked out a GeForce driver on its website developer page, which completely removed the hash limiter from the RTX 3060 and enable the card to mine at full capacity. As soon as the driver became known 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, the leaked driver does not allow multiple 3060 GPUs to mine with full hash rate, as discovered by Editor of Hardwareluxx, Andreas Schilling. In his testing, the GeForce RTX 3060 was run alongside a GeForce RTX 2080 Ti. The RTX 2080 Ti was used as the primary display adapter while the NVIDIA GeForce RTX 3060 was used as a secondary card. And the hash rate of the RTX 3060 is halved in this configuration.

However, miners have already found a way to bypass this limit. You can do so by getting 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.
This was also demonstrated by Hardwareluxx’s Andreas Schilling.
Some users in Korea have also posted about using dummy HDMI connectors to mine on 4 RTX 3060 graphics cards. The miners confirm that there is no mining hash rate drop in Ethereum when using dummy HDMI connectors.
The HDMI dummy connectors are readily available to purchase and are quite cheap but given that they can become popular after this revelation, we may expect massive price hikes and even shortages.
Previously, we also saw miners bypassing the hash rate limiter on the RTX 3060 without any need for BIOS or driver updates when it was bypassed just weeks after its release. The updated Driver Release by Nvidia itself also accidently removed the Hast Rate Limiter from the GPU however the driver is now removed.
