A user from Quasar Zone has come up with a solution to bypass Nvidia’s “Unhackable” Anti-Mining Limiter that was placed on the RTX 3060 GPUs. Coming up with a rather simple solution to solve what Nvidia has called “unhackable”. The limiter was placed on the new series of GPUs to help get these cards into the hands of gamers and not crypto miners. Which is the opinion of nVidea. The raising crypto prices have lead to an increase in demand for Ampere cards. Making them impossible to find for gamers at MSRP prices.
The release of the 3000’s series has been one of the most controversial graphic card launches in recent years. Plague by the perfect storm of rising crypto prices and the coronavirus pandemic. Which has lead to an increase in sales and has put a major strain on manufacturing. Nvidia’s solution for this was to put a limiter on their 3060 graphics cards and selling another set of cards that are made for miners. This in hopes would allow for more gamers to be able to get their hands on an RTX 3060. But the whole limiter has been a controversy all on its own. nVidea by mistake released a beta driver that disabled the limiter. Allowing users once again to be able to mine Ethereum. This beta driver did come with some limitations of course.
Limitations on the Beta Driver
The beta driver doesn’t completely unlock the cards for Ethereum mining. There are still some restrictions. The driver will only unlock a card if Geforce RTX 3060 is communicating through a PCIe 3.0 x8 or greater. Making PCIe x 1 riser useless. Also, the card needs to be plug into an HDMI port or DisplayPort output. This is all used to simulate that it is connected to a computer to play video and not a mining rig.
This is leaving certain conditions to be met before miners are able to unlock the card for mining use. First, they will need a motherboard that has multiple PCIe 3.0 x8 slots. So they are able to run multiple cards and once. Secondly, they will need to plug each card into a monitor. Which will drive up the cost of your mining rig significantly. Unless you use an HDMI Dummy cable which can be purchased on Amazon for as little as $5.99. This will trick nVidea driver into thinking there is a display actually present and you won’t have the need to go and buy an added monitor. This is exactly what the user from Quasar Zone figured out.
Hacking the unhackable
The Quasar user has proved that there is a workaround to get a functional 4 way Geforce RTX 3060 setup. With each card having had a rate of around 48 MH/s giving a grand total of 192 MH/s. He didn’t even have to use a modern CPU or motherboard for that matter. The rig was running a dual-core Intel Pentium G3220 with a Gigabyte G1. Sniper 5 motherboard. Gear that he probably had laying around from previous builds. The user did confirm that it will work on a Maximus VI Extreme as well. There might be some trouble with cooling but nothing a riser won’t be able to fix to separate the cards further away from each other. There is room for improvement but this could be the start of something greater.
This bypass comes to prove a point that Nvidia’s unhackable fix didn’t take too long to get past. Opening up the door for someone to perfect this on a much larger level eliminating the need for the fix in the first place. Having the ability to bypass the fix is one thing but to run it on scale is going to be another challenge.
