43.05 MH/s · FiroPow · network 14.28 GH/s. A GeForce RTX 3090 solo mining Firo (FIRO) has about 635 blocks per year, i.e. an expected block roughly every 13.8 hours for the full 0.3100 FIRO reward.

GeForce RTX 3090 on Firo — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 3090 on Firo (FIRO) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Firo with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (43.05 MH/s) can solo mine Firo (FIRO) via a solo pool. At Firo's 14.28 GH/s FiroPow network that is about 635 blocks per year — expected one block roughly every 13.8 hours, for the full 0.3100 FIRO 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 Firo

The GeForce RTX 3090 is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 8 tracked models on Firo, it ranks #8 in electrical efficiency (138,862.26 H/W) and #5 in raw hashrate (43.05 MH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 3090 (310 W) pulls about 7.44 kWh per day (226.5 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.51 USD per day (15.63 USD/month or 188 USD/year). Statistically that year returns 634.90 blocks, worth about $186 — you would burn roughly 1x more in electricity than that reward is worth.

The operational breakeven threshold is 0.068 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): +0.21 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.01 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.38 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Firo must trade at or above 0.9527 USD at standard industrial power (0.069 USD/kWh), or 1.66 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 13.8 hours, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~42.5 min (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~9.6 hours (Nominal median, power cost: ~0 USD)
• Bad luck streak (5% Odds): Can stretch up to ~2 days (1-in-20 extended dry spell, power cost: ~1 USD)

High Variance Alert: In a 1-in-20 severe drought (~2 days), cumulative electricity burned (~1 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 3090 Price & Estimated ROI

Current market price: $580–$720 (estimated market price, median $650) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 173 days.

How the odds have moved

Firo's network hashrate has been essentially flat since 2026-09-17, from 14.27 GH/s to 14.28 GH/s — so your odds are unchanged.

Where to point a GeForce RTX 3090 at Firo

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 3 solo pools for Firo with their stratum endpoints, fees, and pool hashrates — see Firo solo mining pools:

• woolypooly.com (Fee: 0.9% · Hashrate: 11.40 GH/s)
• ethcore.ru (Fee: 0.5%)
• fenixpool.com (Fee: 1%)

How the odds are calculated

Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block. For this pair: daily chance 82.42%, yearly chance 100.00%.

Frequently Asked Questions: GeForce RTX 3090 on Firo

Can you solo mine Firo with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (43.05 MH/s) can solo mine Firo (FIRO) via a solo pool. At Firo's 14.28 GH/s FiroPow network that is about 635 blocks per year — expected one block roughly every 13.8 hours, for the full 0.3100 FIRO block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is FiroPow ASIC-resistant, and where does the GeForce RTX 3090 stand?

FiroPow is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 3090 ranks #5 of 8 GPUs on Firo. It operates in the Mid-Range Tier (middle quartile), offering solid pool mining throughput with moderate solo variance.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 3090 on Firo?

At 310 W, operating a GeForce RTX 3090 consumes 7.44 kWh/day (226.5 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.51 USD/day (15.63 USD/month). The operational breakeven threshold is 0.068 USD/kWh.

What happens if my GeForce RTX 3090 encounters a severe dry spell on Firo?

Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 2 days, accumulating roughly 1 USD in power costs.
