Mining NEOXA on HiveOS with 3GB cards
The key to the success in mining NEOXA on HiveOS is knowing pool parameters that can be stratum+tcp://minenice.newpool.pw:1120, for example:
Handling messages from Binance Websocket streams
User Data Stream
To subscribe I query listen key:
POST /api/v3/userDataStream
connect to websocket wss://stream.binance.com:9443/stream and send the listen key with the following message :
{
"id": 1,
"method": "SUBSCRIBE",
"params": [
"<my listen key>"
]
}
When Binance accepts the subscription it sends:
{
"id": 1,
"result": null
}
Testing Binance API with Postman
Clone the repository with Postman Collections and Environments:
git clone https://github.com/binance/binance-api-postman.git
Open the root repository folder:
Ethereum Classic (ETC) stopped mining on GeForce GTX 3GB cards

Binance looses its orders
When I query KAVAUSDT order #561657676 with /api/v3/order?symbol=KAVAUSDT&orderId=561657676×tamp={{timestamp}}&signature={{signature}} that normally should return
{
"symbol": "KAVAUSDT",

}
I periodically get
{

"msg": "Order does not exist."
}
see a video on YouTube that demonstrates this effect.

Periodically get ‘device not responding’ error on my HiveOS rig
Once a 2 or 3 minutes I get the following error in the miner log:
grep -i error /var/log/miner/gminer/gminer.log
Error on GPU6: Device not responding, check overclocking settings
and on the following message on the miner screen:

GPU6: DAG has been damaged, check overclocking settings
Miner terminated, watchdog will restart process after 10 seconds
GPU temperature is about 50-60°C, but looks like the memory chips overheat, because there was NVidia error:
