Ambitious miners have managed to hack the supposedly unhackable crypto mining limiter on the new RTX 3060. Only less than a month after the GPU launched, images have emerged that claim a modified driver can be installed to get around the Ethereum hash rate limiter.
When the GeForce RTX 3060 was launched on February 25, Nvidia announced that the graphics card’s mining efficiency was deliberately being reduced by around 50% in a bid to get more of the GPUs directly to gamers.
However, this limitation appears to have been quickly bypassed by Chinese cryptocurrency miners using the hash rate restriction on the graphics card. Some salt is in order here, though, as the bypass’s exact test methodology hasn’t been published.
Efforts to Improve Crypto Mining?
When an RTX 3060 graphics card is hooked up to a PC and runs a crypto mining program, the hash rate initially reads as the average amount and quickly drops soon after detecting the program used. So it is possible whoever took this photo did it fast enough before the limiter correctly kicked in.
There are still questions about how the miners managed such a feat, which was discovered by Twitter user @I_Leak_VN. According to one hypothesis, a downgraded vBIOS did the trick, while another speculates that it was due to modified drivers. RTX 3060 was created to mine Etherium at 20MH/s, but with the bypass in place, the graphics card could hit its total capacity of 45MH/s, which is more than double the performance.
Currently, the only evidence of the hack is a single screenshot and a single post on Facebook; thus, the story could be fake. The screenshot is hardly concrete evidence that the mining limiter has been bypassed, but it is legitimate enough to raise the alarm.
Reliable Hash Rate Limit
If the story is true, then expect potential miners to rush to buy up loads of stock for the RTX 3060 and possibly increase the MSRP once again as retailers try to cash in on the craze. Let’s hope it’s not the case, though, and just some miner who wants to seem wise.
Earlier, some individuals showed concern about how well the limiter would stand against savvy miners. Nvidia has been confident in the hash rate limit stating to PC Gamer how difficult it would be to get around the GPUs’ protections, claiming that end users cannot remove the hash limiter from the driver. They insisted that there is a secure connection between the driver, the RTX 3060 silicon, and the BIOS (firmware) that blocks removing the hash rate limiter.
