When NVIDIA’s RTX 3060 launched about a month ago the big controversy was that NVIDIA implemented a hash rate limiter on the card. This meant that NVIDIA intentionally gimped the card for Ethereum mining, this was of course to deter miners from buying the card. Not long after the release of the card was the hash rate limiter bypassed by NVIDIA themselves and their GeForce 470.05 drivers. This method of bypassing the hash rate limiter was not without its limits as well.
It requires the RTX 3060 to communicate the motherboard using a PCI-Express x8 interface, which means using the common PCI-Express x1 risers are useless. The second thing is that the card had to be connected to a monitor at all times. The x8 interface could be a bit daunting, but there are plenty of older motherboards that have more than just 1 or 2 x8 slots. A user from Quasar Zone used a Gigabyte G1.Sniper 5 motherboard which has four x8 slots. Now all he had to do was somehow bypass the monitor limitation. This was accomplished by using a $5.99 HDMI dummy plug. This makes the card think it is connected to a monitor, when it really is not.
With this workaround in place the user installed four RTX 3060s and was able to achieve a hash rate per card of 48 MH/s or a total hash rate of around 192 MH/s. Pretty awesome! Although finding a motherboard that has more than 1 or 2 x8 slots is going to be pretty hard.
