How Long Will The 3G Memory Graphics Cards Last?
Recently, many miners are concerned about the 3G memory graphics card. Can we use this card mining ETH? How long will the 3g memory graphics cards last? This post could be an answer.
One has to load a dag file into the graphics memory before the graphics card can start mining. Mining ether requires large graphics memory. The Ethereum dag file size has been growing, around 2.43G by now.
Since the dag file is only 2.43G, why do many 3G graphics cards mining report errors, saying that memory is not enough?
Because the dag file is not the only one occupies the memory, the computer operating system also does. Windows 10 takes up about 19–20% of the graphics card memory, Windows 7 and Linux each takes up about 5% of the memory. So, with 3G graphics memory, Window 10 and Windows 7 only have 2.43G and 2.85G memory available for dag files respectively.
Therefore, it is recommended that 3G graphics miners use the Windows 7 OS.
After switching to Window 7, how long can 3G graphics cards be used for ETH mining?
To answer this question, we have to know the growing speed of the dag file size. You can view the dag file size real-time statistics by the website: https://investoon.com/tools/dag_size
The statistics show that the dag size will increase to 2.99G on May 8 of 2019. According to this speed, it will take about 9 months from 2.43G to 2.85G.
So, theoretically, it still has more than half a year you could mine ETH with 3G graphics cards. After that, 3G graphics cards could only be used in other coins with smaller graphics memory requirements.
Hope the analysis above is useful to you. If you found any mistakes about this post, welcome to correct us.
