Jasminer X4-1U Ethash miner

The Jasminer X4-1U is an application-specific integrated circuit miner built for the Ethash algorithm. It targets Ethereum Classic and delivers a rated hashrate of 520MH/s while drawing 240W from the wall. The unit connects to the network through a wired Ethernet link and operates at a stated 80dB noise level. It is supplied as new hardware for continuous mining duty.

Sustained-load behaviour and efficiency

At the quoted 240W power draw the device achieves an energy efficiency of .462J/MH across extended operation. The 5GB DAG memory capacity supports Ethash coins such as ETC but does not accommodate the larger DAG required for ETHW or ETH mining. Continuous 24/7 running is expected, so adequate airflow and a stable power source are necessary to maintain the published hashrate over time.

Pre-order compatibility checks

Verify that the 5GB DAG limit matches the coin you intend to mine before purchase. Confirm that your facility can tolerate 80dB operating noise and that a wired Ethernet connection is available at the deployment site. Ensure the electrical circuit can supply the continuous 240W load with appropriate voltage and connector type for the unit.

Questions about this item

What coins can this miner actually mine with its 5 GB DAG memory?

The 5 GB DAG memory supports ETC mining but cannot handle ETHW or ETH, so only Ethash/Etchash coins with a DAG under 5 GB are viable.

How much electricity will the unit draw at the wall?

Power consumption is rated at 240 W, so at typical electricity rates the unit adds roughly 5.8 kWh per day to your bill.

Is the 80 dB noise level manageable in a home office?

At 80 dB the fan noise is comparable to a loud vacuum cleaner; it is generally too loud for a quiet room and requires a dedicated space or sound-dampening enclosure.
