Why Replace Faulty L7 Hashboards?

A single failing hashboard can cripple your miner’s performance:

• ⬇️ Hashrate Drops: Instability or shutdowns reduce overall mining output.
• ⬇️ Revenue Loss: Lower efficiency = fewer mined coins = profit decline.
• ⬆️ Repair Costs: Delayed replacements risk full-miner failure, increasing expenses.
