Mining with multiple RTX 3060s in parallel? A dummy HDMI fools the Nvidia limiter

The mess which led Nvidia a sabotage his own efforts for to limit performance in the mining of the GeForce RTX 3060 12GB is now history. The driver published by mistake, without a limiter, allows the card to undermine at maximum power, but only in a single configuration and in the presence of at least one PCIe 3.0 x8 slot, demonstrating that the firmware also plays some kind of role.

The danger of seeing mining rigs with multiple GeForce RTX 3060s in parallel therefore seemed averted, but a few days were enough to see this hope fade. The miners, who think one and a hundred do, have in fact understood how easily bypass this constraint too: by purchasing an “HDMI dummy”, that is a dummy HDMI connector (fake) which is actually not connected to anything.

With a disbursement of a few euros it is therefore possible to fool the limiter by simulating connecting the card to a monitor as the primary GPU, thus allowing you to run multiple RTX 3060s in parallel, obviously in the presence of the driver “unlocked” by mistake by Nvidia (now released and therefore easily traceable, albeit removed from the company website).

There are several miners who have demonstrated how this ploy works, for example there are those who put on the track a system with four GeForce RTX 3060s, each capable of reaching around 48 MH / s in Ethereum mining.
