When will my GPU stop mining Ethereum?
Many cards stop mining Ethereum right now because of its ever-growing DAG-file.
🐱🏍 Here at Kryptex, we have some stats:
- 3GB — September 2018 — beyond that point.
- 4GB — August 2020 — right now! 😯
- 6GB — May 2023.
- 8GB — October 2026.
- 11GB — November 2031.
In this article we tell you why the cards are giving up with ETH, how to extend the mining life of most GPUs, and why Kryptex keeps it simple.
Why is DAG-file important?
To deal with Ethereum mining GPUs load DAG-file in the video memory, which is strictly required to do the computations. When it cannot fit into the memory, the miner returns the error.

When would my GPU stop mining ETH?
DAG-file only utilizes free VRAM; thus, if other apps grab a piece of that pie, mining would not start. That is why the exact "end" date varies depending on your PC usage preferences and mining rig display connectivity.
Why does my 4GB GPU have the error? DAG is only at 3.9GB!
Windows and GPU drivers also utilize some VRAM to work correctly. Combined, they take up to 700MB and prevent Ethereum miners from loading the DAG and starting up.
Types of OS
The Dirty OS is the one an average PC user has. It is about web browsers and services, messaging apps, games and other graphics-reliant software installed, which altogether can take up to 700MB of VRAM!
The Clean OS stands for the described Windows/Linux plus drivers case. Minimum waste of memory: launch the Kryptex right after a startup to successfully load DAG-file.
The Integrated means the CPU handles video output; thus, GPU's VRAM is not affected anyhow. Ethereum miners utilize the memory to its fullest when the display is connected to the motherboard.
How to prolong my card's life?⏳
Kryptex packs six different mining algorithms and DaggerHashimoto for Ethereum is just one of them. If it would not be possible anymore for your GPU to stick with ETH, Kryptex will swap the algorithm and remain profitable.

But what about ETH specifically?

TL;DR: three main tips to stay with the Ethereum for another 2-3 months exist:
- Close every other app before start mining.
- Use CPU-integrated graphics for outputs as it uses RAM instead of VRAM. That option grants you an extra of 300MB!
- Install Windows 7 becausse of its lower VRAM requirements and, thus, it frees up space for DAG-file.
So what is that DAG-file precisely? 🤔
DAG-file — is a data chunk containing the history of Ethereum blockchain or, scientifically, it is a Directed Acyclic Graph, which is the same. Miners find blocks via operating with the DAG-file stored in memory; thus, clocking the latter increases the hashrate. We have covered how to properly boost VRAM in that Ehereum guide, check it out! Yet, complex maths and further explanations are irrelevant here, so keep it simple: DAG-file is required for mining. Its increase in size will substantially and irrevocably leave lower-end GPUs with smaller VRAM size behind.
DAG-file, blocks, and epochs.
Each new block is found in 13 seconds. A single Ethereum epoch is 30,000 blocks and has a size of 8MB. Thus, DAG-file gains 100MB each 2 months.
