It looks like more and more people are finding a way to get past NVIDIA’s self-imposed hash rate limiter on the RTX 3060. NVIDIA accidently took it off themselves when they released their GeForce 470.05 drivers. With these drivers you could use the full power of the RTX 3060 to mine ETH, but there were still some limitations. The first was that the card had to be connected to a monitor (which was solved by HDMI dummy plugs) and the second was that the card needed to be connected to a PCI-Express x8 interface. We saw some people using older motherboards which had up to four x8 slots, but that seemed to be the limit of what is possible. Well it seems someone was able to get past that limitation using PCIe risers, but it unclear how they are actually bypassing the x8 limitation.
A user on QuazarZone posted their 7 GPU setup using Zotac RTX 3060 graphics cards.
This setup makes use of the HDMI dummy plugs as well as PCIe risers. The user did not explain how it was done to enable riser support, but did mention it only works with one motherboard. A 7-way RTX 3060 mining rig like that would pull around 1020W of power and would generate around 32 USB of profit each date with power costs included.
This users setup is achieving 336.16 MH/s which is very impressive!
So it appears that in just over a month after the release of the RTX 3060 miners have been able to bypass all mining limitations.
