The coin doesn’t employ a DAG file since it uses the BeamHashIII hash algorithm. Beam (BEAM)īEAM is a Mimblewimble-based cryptocurrency with active developer activities attributing to its viability. Thanks to the general-purpose nature of GPUs compared to ASICs, the rigs can easily make the switch to other coins. When ETH finally rejects 4GB mining rigs, it’s time to look for alternative coins. When it does, we can still, however, repurpose 4GB mining rigs.Īlso Read: Best Crypto Trading Bots What else can you mine with 4G Mining Rigs? Still, these are temporary solutions considering Ethereum is slowly, but surely, moving to the PoS (Ethereum 2.0) mining mechanism.

Unfortunately, on March 8, 2021, the speed will fall to 22 and 14 percent on Linux and Windows OS, respectively. Luckily, even after the 4GB GPUs become obsolete on December 24, miners can still use them for an additional three months but on reduced efficiency.įor example, on Dec 29, the cards are projected to perform at 55 and 35 percent efficiency on Linux and Windows, respectively. This provides enough room to load the DAG file and leverage the other 4GB cards in processing. However, a more solid approach is to replace the GPU0 card with one with more memory such as 6/8GB. Note that this will only work as long as the DAG file can fit in the GPU. Linux OS only sets 120MB aside for VRAM, leaving more room for the DAG file. The problem with Windows OS is that it assigns up to 600MB of the first GPU (GPU0) on the rig to Virtual RAM (VRAM). You can continue maximizing your 4GB mining rigs by switching from Windows to Linux-based operating systems. Fortunately, there’s still hope for 4GB mining rigs to be used on the Ethereum platform. Since these mining rigs make up to 26% of all mining devices on Ethereum, it may see most of these piled in the backyard. Examples of 4GB GPU cards include AMD’s RX470/480/560/580 and Nvidia’s GTX1650/1650 Super and GTX1050Ti. When this happens, it phases out 4GB mining rigs off the Ethereum blockchain. This is forecasted to happen between Dec 23 or 24, 2020. On Ethereum, the dataset is expected to reach 4GB at block 11,520,000. Therefore, when the DAG file size exceeds a GPU rig’s memory capacity, the rig either becomes slow or unable to mine ETH. Apart from mining, how best a mining rig handles the file can increase or reduce its mining speed.

Notably, the file has to be loaded in the GPU’s memory to facilitate active interaction with the blockchain. Its growth is estimated to occur after every 30,000 blocks or 100 mining hours.Įach DAG increment is called an epoch. However, as the protocol grows, so does the DAG. Notably, the function resists mining using ASICs, hence, the prevalence of GPUs on the ETH-powered network.ĭAG is a file containing data that facilitates finding new blocks and verifying transactions on the protocol. DAG is baked in the root of PoW blockchains using the Ethash hashing function. It’s all about the expansion of one type of distributed ledger, Directed Acyclic Graph (DAG).

On December 24, Ethereum’s DAG file will reach the 4GB mark causing 4GB mining rigs on the blockchain to mine at reduced efficiency.Īfter March 2021, their productivity will significantly drop making them unsuitable for ETH mining. There are about 1.5-3 million 4GB GPUs on the market currently mining ETH, who will soon outlive their usefulness on the Ethereum chain, potentially leaving millions of rigs piled in storages collecting dust.īut what if there were other ways you could still utilize 4GB Mining rigs? It’s been a grueling year for miners, with Bitcoin halving its rewards earlier this year and indie miner favorite Ethereum finally launching its Beacon Chain to set it on course towards the promised land of Proof-of-Stake (PoS) Ethereum 2.0.
