[CLOSE] - ETH - goerli testnet mining - Error

[slaritnti]

Goerli is using POS, so it can't be mined.

Hello,

I'm trying to mine some ETH goerli testnet, and I can't mine because of errors. Please take a look below:

1, setup node:

I run this command:

Code:

geth --goerli --http --http.api eth,net,web3,personal,miner,admin,txpool,debug --http.corsdomain '*' --http.addr 127.0.0.1 --http.port 8545

and my node is full synced now with:

Code:

> eth.syncing
false

2, try to mine with GTX 750 Ti by using ethminer 0.19.0-alpha.0

I run this command:

Code:

./ethminer -U -P http://127.0.0.1:8545

here is the error what I got   :

Code:

Thank everyone for reading!

You can´t mine ETH with your card. The DAG is over 4GB and your GPU has only 2GB.

[slaritnti]

Thank you for replying. So is there any way to mine ETH testnet? I tried with CPU mining, but it doesn't work.

[waggy459]

OP to clarify you are just trying to have a completely local testnet set up to learn or do dev work on your local network?  I'd assume the dag in this case will be zero or very small and you should be able to mine on nearly anything.

Seems like the actionable error here is:  method eth_getWork does not exist.  How hard have you searched for this?

Another question, have you restarted or something after starting the geth instance the one time?  It may not be running at start so you need to check to see if geth is still running prior to starting to mine.

I'm running goerli network which is ethereum testnet. And the geth is still running while I try to run ethminer.

About this error: "method eth_getWork does not exist", I tried to search on Google but don't find any solutions. :-s

P/s:

I have mined with CPU and got this error:

Code:

> miner.start(12)
null
> eth.hashrate
0
