Can you solo mine EthereumClassic with a GeForce RTX 3090 Ti?
Yes — a GeForce RTX 3090 Ti (128.13 MH/s) can solo mine EthereumClassic (ETC) via a solo pool. At EthereumClassic's 172.01 TH/s Etchash network that is about 2 blocks per year — expected one block roughly every 211 days, for the full 1.5900 ETC (≈ 13 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.
Hardware Tier & Ecosystem Ranking on EthereumClassic
The GeForce RTX 3090 Ti is categorized in the Commercial / High-Yield Tier (Top quartile hashrate on this network, highly competitive for regular pool revenue or realistic solo mining.). Among all 14 tracked models on EthereumClassic, it ranks #12 in electrical efficiency (366,080.00 H/W) and #2 in raw hashrate (128.13 MH/s).
Electricity Operating Costs & Breakeven
Running a GeForce RTX 3090 Ti (350 W) pulls about 8.40 kWh per day (255.7 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.58 USD per day (17.64 USD/month or 212 USD/year). Statistically that year returns 1.73 blocks, worth about $21.87 — you would burn roughly 10x more in electricity than that reward is worth.
The operational breakeven threshold is 0.007 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): -0.28 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.52 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.95 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, EthereumClassic must trade at or above 76.77 USD at standard industrial power (0.069 USD/kWh), or 133.51 USD at residential power (0.120 USD/kWh).
Bankroll & Variance Risk Simulator
Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 211 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~11 days (1-in-20 fastest discovery, power cost: ~6 USD)
- Median expectation (50% Odds): Block within ~146 days (Nominal median, power cost: ~85 USD)
- Bad luck streak (5% Odds): Can stretch up to ~1.73 yr (1-in-20 extended dry spell, power cost: ~366 USD)
High Variance Alert: In a 1-in-20 severe drought (~1.73 yr), cumulative electricity burned (~366 USD) will exceed the block reward value (13 USD). Pool mining is recommended for risk-averse operators.
GeForce RTX 3090 Ti Price & Estimated ROI
Current market price: $680–$820 (estimated market price, median $750) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 184 days.
How other hardware compares on EthereumClassic
Devices in the same hashrate class, solo mining EthereumClassic at today's difficulty:

How the odds have moved
EthereumClassic's network hashrate climbed 18% since 2026-09-22, from 145.48 TH/s to 172.01 TH/s — so the same rig is now 18% less likely to find a block.
Where to point a GeForce RTX 3090 Ti at EthereumClassic
Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 13 solo pools for EthereumClassic with their stratum endpoints, fees, and pool hashrates — see EthereumClassic solo mining pools:

How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 0.4737%, yearly chance 82.35%.
