optimizer hard hat,Nvidia GeForce RTX 3060 is Indeed Limited for Crypto Mining
It seems that Nvidia did manage to keep their promise to make the new GeForce RTX 3060 GPU limited for crypto mining and thus widely available for gamers as with reduced performance it will not be attractive for miners. We got some sound information regarding the actual performance for mining use for the new GeForce RTX 3060 that is expected to be available starting February 25th or in just a few days. According to Nvidia the new video drivers for the RTX 3060 GPUs are designed to detect specific attributes of the Ethereum cryptocurrency mining algorithm, and will limit the hashrate, or cryptocurrency mining performance to half of what they will normally do. Essentially you will be getting half the hashrate you normally would if the card is running at full performance meaning that instead of the expected hashrate for RTX 3060 in the range of 40-45 MH/s for Ethereum with stock settings and optimized, so with the drivers cutting that in half we were expecting only 20-22.5 MH/s.
It seems that the reality is not that far off from what we were expecting with an MSI GeForce RTX 3060 GAMING X video card apparently starting up with a hashrarte of about 41 MH/s for Ethereum mining with stock settings with 100% TDP. With fans running at automatic settings the MSI GPU runs at around 58% fans and 51 degrees Celsius temperature for the GPU with 117W of power usage. When the miner starts the hashrate quickly drops from 41 to about 21 MH/s, so pretty much in half and even if you close the miner and start it again it starts with the lower hashrate. You need to reboot the PC and then when you run the miner for Ethereum for the first time it will start at 41 MH/s again, but quickly drop that in half again.
With reduced TDP and GPU frequency and overclocked video memory to +1000 MHz in MSI Afterburner the hashrate starts at 45-46 MH/s, but then again very shortly it drops down to about 25 MH/s or once more it is cut in half. So, pretty much what we expected even before we got a confirmation on the actual hashrate that the RTX 3060 GPUs are capable of, though cut in half by the Nvidia driver as a means to drive away crypto miners from that particular video card and also for Nvidia to sell their new line of professional crypto mining products to miners – the Nvidia CMP HX Dedicated Crypto Mining GPUs.
The good news is that already released Nvidia RTX 30 Series GPUs are not affected by this limitation, so only the new RTX 3060 will be limited in half in terms of mining performance. Or to be more specific limited to half Ethereum mining performance by the drivers as apparently other mining algorithms are not affected like ETH is. This means that although the RTX 3060 may not be a popular option for Ethereum mining it could still be a good option for mining other crypto currencies such as Ravencоin (RVN) or VertCoin (VTC).
A quick update regarding the situation with VertCoin (VTC) mining on the new RTX 3060 GPUs… it seems that the VertHash algorithm is also affected from the half hashrate drop that Ethash is experiencing, probably other memory0intensive crypto mining algorithms will be affected as well. Ravencoin’s (RVN) use of KAWPOW and probably ProgPOW as well do not seem to be suffering from reduced hashrate like Ethash and VertHash though, you should be getting 21 MH/s or more for RVN mining. So, the Nvidia GeForce RTX 3060 is not fully limited for mining use, but some of the most profitable mining algorithms at the moment are apparently affected from this! Although the above information was initially verified to be true for Windows mining, it seems that under Linux with an OS like SimpleMining (SMOS) the situation with the limited hashrate on the RTX 3060 is also the same and you get half the hashrate mining Ethereum.
