Yes, it is, but it depends on OS your rig is being powered with. If you use ethOS, you can comfortably use a 4GB RAM, but if you use Windows without virtual memory, you should be using at least 8GB RAM.
Is 4GB of RAM enough for mining?
RAM — Higher RAM does not mean that you get a better mining performance, so we recommend using anywhere between 4GB and 16GB of RAM. When deciding what size RAM best suits your needs, look at the operating system for mining and whether or not virtual memory is used.
Can you still mine with 4GB GPU?
You might also notice reduced hashrate or instability. If you are using our mining OS you might still be able to mine ETH even with your 4GB cards. Select the latest TeamRedMiner for AMD, Phoenix miner for Nvidia, or lolMiner for Nvidia or AMD, and you will be fine for at least some short period.
Can a 4GB GPU mine Ethereum?
Although the dag size is 4 GB or even more as it continues to increase, the 4 GB cards can continue mining Ethereum as long as we follow a few specific steps. First, we have to use a Linux-based OS, that’s because Windows requires a lot more VRAM from the GPU and that will limit our mining even more.
