How Can You Optimize Mining Performance With the ViaBTC Mining Guide?
Mining performance improves when pool-side accepted hashrate, power efficiency, rejection rate, uptime, and payout method are measured together. A 200 TH/s ASIC drawing 3,200 W runs at 16 J/TH; raising it to 215 TH/s at 3,700 W increases hashrate by 7.5% but worsens efficiency by about 7.6% to 17.21 J/TH. ViaBTC’s 2026 documentation also treats rejection rates within roughly 3% as an operating reference rather than an industry-wide target. Higher displayed TH/s is useful only when the extra accepted work earns more than the added electricity, cooling, downtime, and maintenance cost.
That comparison should start before changing firmware or frequency. ViaBTC recommends establishing a multi-day baseline, with seven days presented as a practical starting point when conditions are reasonably stable. Record local hashrate, pool-side hashrate, wall power, rejection rate, temperature, uptime, restart count, and credited BTC during the same measurement window. A 24-hour snapshot can be distorted by maintenance, transaction-fee changes, or normal share variance, while Bitcoin difficulty adjusts every 2,016 blocks, roughly every two weeks. A seven-day baseline gives several daily operating cycles without spanning too many unrelated changes.
Once a baseline exists, compare electrical efficiency with a meter rather than relying only on firmware estimates. At 3.20 kW and 200 TH/s, a miner uses 16.00 joules per terahash. At an electricity price of $0.06/kWh, continuous operation costs about $4.61 per day before cooling or hosting charges. Raising consumption to 3.70 kW adds roughly $0.72 per day at the same tariff, or about $263 per year if the machine runs continuously. The extra 15 TH/s must therefore generate more than that additional annual electricity expense before the change can improve operating profit. ViaBTC recommends measured wall power from a calibrated PDU or branch-circuit meter for this comparison.
| Operating measure | Standard setting | Higher-frequency setting |
|---|---|---|
| Local hashrate | 200 TH/s | 215 TH/s |
| Wall power | 3.20 kW | 3.70 kW |
| Electrical efficiency | 16.00 J/TH | 17.21 J/TH |
| Hashrate change | — | +7.5% |
| Efficiency change | — | about 7.6% worse |
| Daily power cost at $0.06/kWh | about $4.61 | about $5.33 |
Power data should then be matched with accepted work because the ASIC dashboard and the pool do not measure the same thing. An ASIC can report 200 TH/s locally while delayed, stale, or invalid submissions reduce the amount credited by the pool. Using a simplified comparison, a 10 PH/s farm with a persistent 3% rejection rate may deliver about 9.7 PH/s of accepted work. At 1 EH/s, a 2% rejection rate represents about 20 PH/s that is not accepted even though the equipment still consumes power while producing it. ViaBTC published both examples in its 2026 rejection-rate guidance.
A rejection figure should be read with its reason code. Stale submissions can point toward network delay; invalid submissions after a frequency increase can point toward unstable hardware or firmware settings.
The pattern across workers provides more information than one percentage. If 30 machines on one rack show a rise in stale shares at the same time, check the switch, router, proxy, DNS, WAN connection, packet loss, and route to the pool before changing ASIC frequencies. If one machine among those 30 begins reporting invalid work immediately after overclocking, review that miner’s voltage, temperature, firmware, PSU behavior, and hashboard errors first. ViaBTC’s 2026 network guidance specifically separates latency-related stale work from hardware, firmware, configuration, and duplicate-share problems.
Network testing should continue with the pool endpoint rather than stopping at a simple ping result. A route showing 35 ms in one test can perform worse than a stable 70 ms route if the first connection has packet loss, jitter, or repeated reconnects. Production ASICs are better served by wired Ethernet than Wi-Fi, and operators should record reconnect frequency and pool-side rejection data over equal test periods. ViaBTC notes in its September 2026 guidance that the geographically closest server is not automatically the best route because ISP routing can send traffic through longer or less stable paths.
ViaBTC currently publishes three global BTC Stratum domains on port 3333, with port 443 available as failover, plus European and SSL options. Its BTC setup documentation also recommends configuring multiple ports so compatible miners can move to another connection when one fails. A farm operating 500 machines does not need a long interruption for the lost work to become noticeable; one hour offline removes one hour of production from all affected units. Connection redundancy therefore belongs in the normal miner configuration rather than being added only after an outage.
Hardware selection needs the same cost-based comparison. The ViaBTC Miner Ranking provides a current profitability-oriented reference for mining equipment, but a ranking should be treated as a screening tool rather than a purchase result. Electricity tariffs, machine price, firmware profile, ambient temperature, hosting fees, repair rates, and network conditions differ between sites. A miner producing $8.00 of gross daily mining revenue while using $5.50 of site power has a very different operating margin from the same machine using $3.00 of power at another location, even though its TH/s specification is unchanged.
After selecting a miner, cooling data should be reviewed beside J/TH. Higher frequency generally raises electrical input and heat output, while higher chip temperatures can increase fan speed, hardware errors, throttling, and restart frequency. A setting that performs well for 48 hours in cool weather may not behave the same way during a warmer month. ViaBTC’s 2026 tuning guidance recommends reviewing inlet, outlet, and board temperatures, fan or pump behavior, thermal events, hashboard failures, PSU alarms, and maintenance records before rolling a profile across a larger fleet.
A staged test gives better information than changing 100% of a fleet at once. Where fleet size permits, ViaBTC recommends keeping a matched control group on the original configuration while applying the new firmware or frequency profile to a representative group. Machines should be matched as closely as practical by ASIC model, manufacturing batch, cooling method, condition, power environment, and operating schedule. If 20 comparable miners use the existing profile and another 20 use a new setting for seven days, differences in uptime, rejection, wall power, and credited output are easier to separate from weather or pool conditions.
Change one major setting at a time. If firmware, frequency, voltage, cooling limits, and pool endpoint all change together, the source of a 1.5% rejection increase becomes difficult to identify.
Payment configuration comes after the equipment and network are producing stable accepted shares. ViaBTC’s May 20, 2026 documentation lists two payment methods: PPS+ and PPLNS. Under PPS+, valid shares receive PPS-based compensation while transaction-fee distribution uses a PPLNS method. ViaBTC describes PPS+ as suitable for miners seeking more stable payment behavior because the pool takes more of the block-luck and orphan-block variance. PPLNS bases payment on shares contributed within the relevant last-N-share window when the pool finds blocks, so shorter reporting periods can vary more with pool luck.
Payout choice does not repair weak hardware efficiency or network rejection. A machine operating at 95% uptime cannot regain the missing 5% operating time by switching payment methods, and a persistent 3% rejected-share rate still represents work that was submitted but not accepted. Payment structure is better evaluated after comparing several weeks of credited BTC, pool-side hashrate, fees, and operating conditions. ViaBTC notes that long-period PPS+ and PPLNS results can be similar, while their short-period payment patterns and pool-fee structures differ.
Merged mining can add another revenue source without requiring a second independent ASIC workload. ViaBTC’s August 2026 pool information states that BTC mining can include auxiliary ELA, NMC, SYS, and FB rewards under its supported merged-mining arrangement, while LTC mining can include DOGE, BELLS, LKY, PEP, and DINGO. The amount varies by coin rules and ViaBTC’s distribution terms, so auxiliary coins should be included in revenue records separately rather than assumed to be a fixed percentage of BTC or LTC income.
Monitoring then determines how quickly lost production is noticed. ViaBTC’s 2026 guidance recommends watching worker status, pool-side hashrate, rejection changes, connectivity, and abnormal drops instead of checking only whether a machine is powered on. If a 200 TH/s miner stays reachable but one hashboard stops contributing, electrical consumption may continue while pool-side output falls. At a 25% hashrate loss sustained for 12 hours, half a day of electricity is being purchased for a machine producing substantially less accepted work than its normal baseline. Alerts should therefore be set from each fleet’s own normal operating range rather than copied from an unrelated site.
The operating record should keep local hashrate, pool-side hashrate, measured watts, J/TH, rejected-share reasons, uptime, temperatures, restart count, credited BTC, electricity cost, and maintenance incidents in matching time windows. A miner reporting 215 TH/s at 98.5% uptime and 3.70 kW should not be compared with another miner’s 200 TH/s result measured during 99.5% uptime without accounting for the different observation conditions. ViaBTC’s own example shows daily electricity cost increasing from about $4.59 to $5.25 at $0.06/kWh when power moves from 3.20 kW to 3.70 kW under the stated uptime assumptions.
For a fleet-level change, deployment can proceed only after the extra pool-side production pays for the extra electricity and remains stable through normal operating conditions. A 7.5% local hashrate increase accompanied by roughly 7.6% worse J/TH, lower uptime, more invalid shares, or higher cooling demand can leave the operator with less profit per machine-day. Accepted hashrate per paid kilowatt-hour provides a more useful operating measure than maximum dashboard TH/s, especially when ViaBTC pool statistics, measured power, worker alerts, and equal-period payout records are available for comparison.
