Product Details

Jasminer X4-QZ 840MH Ultra Efficient Quiet Ethash Miner for Ethereum Classic

Older Jasminer quiet Ethash at a hashrate that still holds relevance. The X4-QZ at 840 MH/s and 340W runs 40 dB in a compact 3U rack mountable form factor. This is the X4 generation, predecessor to the X16-Q series (1.75 to 2.05 GH/s). Less output but also less power.

Rack mountable is an unusual feature for a 40 dB home tier device. The 3U form factor means the X4-QZ can slot into a standard server rack alongside other equipment. For operators who want organized, rack based ETC mining at home quiet noise levels, this is one of very few options that fits standard 19 inch rails.

340W on universal 100 to 240V. At 110V draws about 3.1 amps. Standard outlets handle it easily. Daily electricity at $0.07 per kWh: $0.57. Monthly: $17. The X4-QZ undercuts the newer X16-Q series on operating cost at the expense of lower total output.

The X4 series includes: X4 Brick (65 MH/s, 30W, novelty), X4-QZ (840 MH/s, 340W, this model), X4-C 1U (450 MH/s, 240W, rack), X4-1U (520 MH/s, 240W, rack), and X4 (2.5 GH/s, 1,200W, industrial). The QZ hits the sweet spot of quiet and productive.

450 x 350 x 132mm at 12.0 kg. 100-240V input. Ethernet. 5 - 40 °C. Jasminer firmware for pool configuration. Daily electricity at $0.07 per kWh: $0.57. Monthly: $17. Compare against Ethereum Classic mining revenue at 840 MH/s and current difficulty before purchasing.

Before purchasing the X4-QZ: verify current Ethereum Classic mining revenue at 840 MH/s exceeds $0.57 daily electricity. when daily revenue exceeds $0.57 in electricity, the X4-QZ is generating net value. mining at a loss is a bet that Ethereum Classic tokens mined cheaply today are worth more tomorrow.
