2GB GPU Ethereum Mining Guide 2018
In late 2016, Ethereum's DAG file size exceeded 2GB which meant 2GB Graphics Cards were no longer capable of mining ethereum. All cards 2GB and below were forced to mine newer, less difficult algorithms. Crypto-Miners had to settle for less profit long term... until now.

In late 2017, Ethereum forked in many directions and 2 of those forks were Musicoin and Expanse. Musicoin's DAG size is currently 1.59GB and Expanse's DAG is 1.27GB, both easily below 2GB currently. Because the DAG files fit easily on 2GB cards, those GPU's will perform just as fast as when Ethereum's DAG was below 2GB. Because the difficulty is so low on these forked ethereum coins, most day's you will make equal in profit to ethereum mining, and in recent days has exceeded even ethereum's profitability.
Here is what you will need:
Once you have logged into Mining Pool Hub, click the "Hub Workers" section. In the "Add New Workers" box, create a worker named "Musicoin" and a worker named "Expanse". Make sure to set the password to "x" for both workers to simplify the next step.
In the Hub Workers configuration box on the same page, set the worker "Musicoin" to the job of "Musicoin" and set the worker "Expanse" to the job of "Expanse".
Then click the "Auto-Exchange" section and change the auto-exchange coin to "Ethereum".
Now extract the contents of the "Claymore Dual Ethereum Miner" file you downloaded earlier to a folder on your desktop. Open that folder and make sure its contents are visible. Right click the file "start.bat" and left-click "edit".
Copy the following batch script into the notepad you have open and press "save" and not "save-as". This allows the file bat file to be easily started. Make sure to change the "USERNAME" placeholder with the one you registered with.
Use this for Expanse:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
EthDcrMiner64.exe -mport 0 -ethi 7 -mode 1 -asm 2 -epool us-east.ethash-hub.miningpoolhub.com:20565 -ewal USERNAME.expanse -eworker USERNAME.expanse -esm 2 -epsw x -allcoins 1 -dpool stratum+tcp://hub.miningpoolhub.com:20550 -dwal USERNAME.expanse -dpsw x -dcoin sc
Use this for Musicoin:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
EthDcrMiner64.exe -mport 0 -ethi 7 -mode 1 -asm 2 -epool us-east.ethash-hub.miningpoolhub.com:20585 -ewal USERNAME.musicoin -eworker USERNAME.musicoin -esm 2 -epsw x -allcoins 1 -dpool stratum+tcp://hub.miningpoolhub.com:20550 -dwal USERNAME.musicoin -dpsw x -dcoin sc
Now double click "start.bat". If you followed my steps correctly, you should get a window like this:
Congratulations! You are now mining ethereum using a 2GB card. Your welcome!

Hey cool! Okay so I have a question. If I have an old desktop that has 1695MB available graphics memory, does that mean I can mine Expanse using mining pool hub?
Visiting from SMG group, keni posted a memberlist. Checking out your blog. Very interested in mining but I have only old computers lol
Its possible, although the DAG file is just a smidgen under that size, but there is no harm in trying, Make sure you crank your fans and blow the dust out of the vents first.
Good points. Thank you!
