Dual Mining Solo Setup: Mine Two Coins with One Rig Guide

Here’s the thing: Most miners think you can only mine one coin at a time. But dual mining lets you squeeze extra hashrate out of your GPU by mining two different coins simultaneously — and yes, you can do it while solo mining.

I discovered dual mining by accident when I was messing around with my RTX 3070. Trust me on this: I was solo mining Alephium and noticed my GPU wasn’t even hitting 100% utilization. Turns out some algorithms don’t fully load your card, which means you’re leaving free hashrate on the table.

That’s where dual mining comes in.

The basic idea: Your GPU has different components that handle different types of calculations. Some mining algorithms only use the core, leaving the memory controller mostly idle. Dual mining exploits this by running two miners simultaneously — one using the core, another using the memory bandwidth.

But here’s what nobody tells you: Dual mining requires careful configuration, and your chances of finding solo blocks actually depend on which coin combinations you pick. Let me walk you through the entire setup process, from hardware selection to software configuration.

Step 1: Understanding Which Coins Support Dual Mining Solo Setups

Not every coin combination works for dual mining. The fundamental requirement is that the two algorithms must use different GPU resources so they don’t compete with each other.

The most common dual mining combinations for solo mining:

• Primary (Core-Heavy): Ethash variants, KawPow, Blake3, FiroPow
• Secondary (Memory-Light): Blake2s, SHA256d, Autolykos

Here’s what works well for solo mining specifically: You want your primary coin to be something with reasonable solo block odds, and your secondary coin to be either high-difficulty (so you’re basically lottery mining) or low-difficulty (frequent small blocks).

My current setup mines Clore.ai on Blake3 as the primary (core-heavy) and simultaneously runs a SHA256d miner on the same GPU targeting an obscure merge-mined coin. The Clore mining runs at about 95% normal hashrate, while the secondary coin adds basically free lottery tickets.

Some popular combinations for solo GPU mining:

• Alephium (Blake3) + Kaspa (kHeavyHash): Both use different execution units, can run 90%+ efficiency on each
• Neoxa (KawPow) + Ergo (Autolykos): KawPow is compute-intensive, Autolykos is memory-hard
• Vertcoin (Verthash) + Radiant (SHA512256d): Verthash saturates memory, Radiant uses compute cores

What doesn’t work: Trying to dual mine two memory-hard algorithms like Ethash + Verthash. Your hashrate will tank on both coins, and you’re actually worse off than single mining.

The solo mining angle here is important. With pool mining, dual mining makes sense even if your secondary hashrate drops to 60-70% because you’re getting consistent payouts. But with solo mining, you need to calculate your actual block finding probability for each coin independently. If your primary coin hashrate drops from 100 GH/s to 85 GH/s due to dual mining, that’s a 15% reduction in your solo block odds — you need the secondary coin to have realistic solo chances to justify the tradeoff.

Step 2: Hardware Requirements for Dual Mining Solo Configuration

Dual mining is GPU-exclusive. ASICs are purpose-built for one algorithm and can’t dual mine. So if you’re running Antminer S19 XP solo mining for Bitcoin, this strategy won’t apply to you.

Here’s what you need:

GPU Requirements:

• At least 8GB VRAM (some algorithms like Verthash need more)
• Good cooling — dual mining generates more heat than single algorithm
• Efficient power delivery — you’ll be pulling near-maximum TDP

The sweet spot for dual mining solo setups: Mid-range modern GPUs with good memory bandwidth and core count. Cards like RTX 3070, RX 6700 XT, or RTX 4060 Ti give you enough horsepower for decent solo odds on smaller coins while supporting dual mining configurations.

Power Supply Considerations:

Dual mining pushes your GPU harder than single algorithm mining. Your card will pull closer to its maximum TDP, sometimes even exceeding it depending on your overclock settings.

For a single-GPU setup, I’d recommend at least a 750W PSU with 80+ Gold efficiency. If you’re running multiple cards for solo mining (which I do with three RTX 3060 Tis), you’ll need a 1200W or larger PSU.

Cooling Setup:

No joke: I melted the thermal pads on my first dual mining GPU because I didn’t account for the extra heat. Dual mining generates maybe 10-15% more heat than single algorithm mining because both the GPU core and memory are working hard simultaneously.

What you actually need:

• Case with good airflow — at least two intake fans, one exhaust
• Quality thermal paste on the GPU die (replace factory paste if it’s older than 2 years)
• Monitor VRAM temperatures specifically — many monitoring tools only show GPU core temp

My current setup uses a Fractal Design Meshify C case with three 120mm intake fans and one 140mm exhaust. GPU core temps stay around 62-65°C while dual mining, VRAM temps around 78-82°C. That’s acceptable for 24/7 operation.

Step 3: Software Configuration for Dual Mining Solo

Here’s where it gets technical. You’ll need to run two separate mining programs simultaneously, each pointed at your solo mining pool (or node if you’re running your own).

The most reliable dual mining software combinations:

Option 1: BzMiner + lolMiner

BzMiner as your primary miner handles the core-heavy algorithm, while lolMiner runs in the background on lower intensity targeting the secondary coin. This combo works great for Alephium + Kaspa dual mining.

Option 2: SRBMiner + NBMiner

SRBMiner for your primary coin, NBMiner for secondary. Both support intensity controls and work well with solo mining pools like Public-Pool.io.

Option 3: T-Rex Miner (Built-In Dual Mining)

T-Rex supports native dual mining for some algorithm combinations. Easier to configure than running two separate miners, but you’re limited to the algorithm pairs that T-Rex supports.

Basic configuration example for dual mining Alephium (primary) + Kaspa (secondary):

BzMiner for Alephium (primary):

bzminer.exe -a alph -w YOUR_ALPH_WALLET -p stratum+tcp://solo-alph.POOL_ADDRESS:PORT --nc 1

lolMiner for Kaspa (secondary, reduced intensity):

lolMiner.exe --algo KASPA --pool solo-kas.POOL_ADDRESS:PORT --user YOUR_KAS_WALLET --dualmode 1 --dualfactor 30

The key parameter here is --dualfactor 30 which tells lolMiner to use only about 30% of the GPU’s available resources for Kaspa mining. You’ll need to experiment with this value — start low (20-25) and gradually increase until you find the sweet spot where both miners run stable.

On my RTX 3070, I can run Alephium at 1.8 GH/s (down from 2.0 GH/s solo) while simultaneously pulling 180 MH/s on Kaspa (compared to 600 MH/s if I single-mined Kaspa). That’s 90% efficiency on my primary coin plus essentially free hashrate on the secondary.

Step 4: Optimizing Hashrate and Power Draw

Dual mining requires different overclock settings than single algorithm mining. You need to balance core clock, memory clock, and power limit to maximize efficiency on both algorithms simultaneously.

The process I use:

Step 4.1: Establish Single-Mining Baselines

Before you start dual mining, record your optimal overclock settings for each coin individually:

• Core clock offset
• Memory clock offset
• Power limit percentage
• Fan speed required to maintain safe temps

For example, when I single-mine Alephium on my RTX 3070, optimal settings are: +100 core, +800 memory, 65% power limit, 70% fan speed.

When I single-mine Kaspa: -200 core, +1200 memory, 55% power limit, 60% fan speed.

Step 4.2: Start Conservative for Dual Mining

Your dual mining overclock will be somewhere between these two profiles. Start conservative:

• Core clock: Average of your two single-mining values
• Memory clock: Take the higher of your two single-mining values
• Power limit: Set to 80-85% (higher than either single-mining config)

For my Alephium + Kaspa setup, I started with: +0 core, +1000 memory, 80% power limit.

Step 4.3: Tune Based on Monitoring

Run your dual mining setup for 15-20 minutes and monitor:

• GPU core temperature (target: under 70°C)
• VRAM temperature (target: under 85°C)
• Hashrate stability on both miners
• Power draw at the wall
• Invalid shares / rejected work

Use MSI Afterburner or similar to adjust settings in small increments. I typically adjust in these steps:

• Core clock: ±25 MHz at a time
• Memory clock: ±50 MHz at a time
• Power limit: ±2% at a time

After about 3-4 hours of testing different configurations, my optimal dual mining settings ended up being: +75 core, +1100 memory, 78% power limit. This gives me 1.85 GH/s on Alephium and 185 MH/s on Kaspa, pulling 195W from the wall.

Compare that to single-mining Alephium at 2.0 GH/s pulling 140W. I’m sacrificing 7.5% of my Alephium hashrate but gaining free Kaspa hashrate for only 55W additional power draw. Whether that tradeoff makes sense depends on your electricity cost and the current block rewards for each coin.

Step 5: Calculating Solo Mining Odds for Dual Mining Setup

This is where dual mining solo gets interesting. You need to calculate your block finding probability for each coin independently, then decide if the combined expected value justifies running both miners.

Formula for Solo Block Odds:

Your probability of finding a block per day = (Your Hashrate / Network Hashrate) × Blocks Per Day

Let me walk through my actual setup as an example:

Alephium (Primary):

• My hashrate: 1.85 GH/s (dual mining)
• Network hashrate: ~160 TH/s (as of writing)
• Blocks per day: ~21,600 (roughly one per 4 seconds across all shards)
• My share: 1.85 GH / 160,000 GH = 0.0000115625
• Expected blocks per day: 0.0000115625 × 21,600 = 0.25 blocks

So roughly one block every 4 days on average. Current Alephium price: $0.0787. Block reward is 3.125 ALPH, so each block is worth about $3-4 depending on the day.

Kaspa (Secondary):

• My hashrate: 185 MH/s (dual mining)
• Network hashrate: ~180 TH/s (as of writing)
• Blocks per second: roughly 1 per second
• My share: 185 MH / 180,000,000 MH = 0.00000103
• Expected blocks per day: 0.00000103 × 86,400 = 0.089 blocks

So roughly one block every 11 days on average. Current Kaspa price: $0.0293. Block reward varies but averages around 270 KAS, worth roughly $35-40 per block.

For comparison, check out this solo mining probability chart to see how your hashrate stacks up against different network difficulties.

Combined Expected Value:

Alephium: $3.50 × 0.25 = $0.875/day
Kaspa: $37 × 0.089 = $3.29/day
Total: ~$4.16/day expected value

But here’s the reality check: These are expected values based on averages. Solo mining is variance-heavy. I might find two Kaspa blocks in one day and then go three weeks without finding anything. That’s the nature of solo mining with relatively low hashrate.

My electricity cost is about $0.12/kWh, and I’m pulling 195W dual mining, so that’s 195W × 24h × $0.12 = $0.56/day in power. So my theoretical profit is $4.16 – $0.56 = $3.60/day.

Of course, some months I find way more blocks than expected. Last month I found 5 Alephium blocks (lucky streak!) and 2 Kaspa blocks, which was about $45 total. Other months I’ve gone nearly dry. That’s solo mining for you.

If you want more realistic projections based on statistical analysis, check this guide on solo mining success rates by hashrate.

Step 6: Solo Pool Selection and Configuration

For dual mining solo, you’ll need to connect each miner to a solo mining pool. Running your own nodes for two different coins simultaneously is possible but requires significantly more setup complexity — I’d only recommend that if you’re already comfortable with node management.

Recommended Solo Mining Pools:

Public-Pool.io

My go-to for solo GPU mining. Supports most GPU-mineable coins including Alephium, Kaspa, Neoxa, Vertcoin, and more. Zero fees for solo mining (they only charge on PPLNS mode). The pool keeps 100% of your block reward and sends it directly to your wallet when you find a block.

Configuration is straightforward:

stratum+tcp://solo-COIN.public-pool.io:PORT
Username: YOUR_WALLET_ADDRESS
Password: x

The pool shows your submitted shares in real-time, which is actually motivating when dual mining — you can see both of your miners working simultaneously.

SoloPool.org

Another solid option, particularly good for less common coins. They support a wide variety of algorithms and have detailed statistics pages showing network difficulty, your submitted shares, and estimated time to find a block (though that estimate is pretty meaningless with solo mining’s variance).

WoolyPooly Solo

Good for Ergo and some other GPU coins. Their infrastructure is stable and they have servers in multiple regions, which helps reduce latency.

For my Alephium + Kaspa dual mining setup, I use Public-Pool.io for both coins. The configuration files look like this:

BzMiner config for Alephium:

bzminer.exe -a alph -w YOUR_ALPH_WALLET -p stratum+tcp://solo-alph.public-pool.io:3104 --nc 1 --pool_password x

lolMiner config for Kaspa:

lolMiner.exe --algo KASPA --pool solo-kas.public-pool.io:3112 --user YOUR_KAS_WALLET --dualmode 1 --dualfactor 30 --pass x

Make sure you replace YOUR_ALPH_WALLET and YOUR_KAS_WALLET with your actual wallet addresses. Unlike pool mining where the pool tracks your balance, solo mining sends the entire block reward directly to your wallet when you find a block — so triple-check those addresses before you start mining.

Honest Assessment: Is Dual Mining Solo Worth It?

Let me be straight with you about the economics and the realities of this strategy.

The Good:

• You extract more value from your GPU by using otherwise-idle resources
• Dual mining increases your chances of hitting something — even if both odds are individually low
• It’s honestly pretty fun watching two miners work simultaneously
• Lower barrier to entry than buying multiple GPUs or ASICs

The Reality Check:

Unless you have cheap electricity (under $0.10/kWh) or you’re mining coins with low network hashrates, dual mining solo is a hobby, not a business. Let me break down the math honestly.

My setup pulls 195W for expected earnings of $4.16/day based on average block luck. That’s 4.68 kWh per day. At my electricity rate of $0.12/kWh, I’m netting about $3.60/day in theory.

But solo mining variance means some days I earn $0, other days I might hit a block worth $40. Over a 30-day period, my expected earnings are around $125, minus $17 in electricity, for a net of $108/month.

Compare that to pool mining the same coins: I’d earn roughly $3.80/day consistently (about $114/month minus electricity), but I’d pay 1-2% pool fees and have to meet minimum payout thresholds.

The difference? About $10-15/month in my favor for solo mining, but with massive variance. Some months I’m up $50 versus pool mining, other months I’m down $30.

Trust me on this: If you need consistent income to cover your electricity bill, pool mine. If you can afford the variance and you mine for the excitement of finding blocks, solo dual mining is actually pretty fun.

Also worth reading: Solo mining bear market strategy — because coin prices fluctuate wildly and your profitability calculation today might be totally different in three months.

Electricity Cost Warning:

If your electricity is above $0.15/kWh, dual mining solo probably doesn’t make financial sense unless you’re targeting coins with very low network hashrates. The extra power draw from dual mining (typically 30-50W more than single mining) eats into your already-thin margins.

Check out these strategies for reducing solo mining electricity costs if you want to make the economics work better.

Hardware Wear:

Dual mining pushes your GPU harder than single algorithm mining. You’re running both the core and memory near capacity 24/7. That means:

• Higher temps = faster thermal paste degradation
• More power cycling = more stress on VRMs and capacitors
• Fans running at higher speeds = shorter fan bearing life

My first dual mining GPU (an RTX 2026) developed a fan bearing issue after about 14 months of 24/7 dual mining. Replacement fans cost me $40. Factor in hardware maintenance when calculating your ROI.

For what it’s worth, I still dual mine because I genuinely enjoy it. The thrill of checking Public-Pool in the morning and seeing “BLOCK FOUND!” makes it worthwhile for me, even if the strict economics are marginal. But I’m a 13-year-old kid mining on his gaming PC — I’m not trying to pay rent with this setup.

Alternative Dual Mining Combinations Worth Testing

Beyond the common Alephium + Kaspa combo I use, here are some other dual mining solo setups worth considering:

Neoxa (KawPow) + Ergo (Autolykos):

Neoxa is a newer KawPow coin with lower network hashrate, making solo block finds more realistic. Ergo as a secondary gives you decent solo odds if you have 200+ MH/s.

Expected hashrate on RTX 3070: ~22 MH/s Neoxa (primary) + ~80 MH/s Ergo (secondary)

Vertcoin (Verthash) + Kaspa (kHeavyHash):

Vertcoin is strongly ASIC-resistant and has a small but dedicated community. Network hashrate is low enough that solo mining is viable with even a single GPU.

Expected hashrate on RTX 3070: ~1.2 MH/s Vertcoin (primary) + ~200 MH/s Kaspa (secondary)

Firo (FiroPow) + Radiant (SHA512256d):

Firo uses FiroPow which is compute-intensive, while Radiant is memory-light. Both have relatively low network hashrates compared to major coins.

Expected hashrate on RTX 3070: ~15 MH/s Firo (primary) + variable on Radiant depending on config

Warthog + Clore.ai:

Warthog is GPU-optimized and ASIC-resistant. Clore.ai uses Blake3 which is very efficient. This combo works because Warthog saturates compute while Blake3 is memory-bound.

Expected hashrate on RTX 3070: ~120 KH/s Warthog (primary) + ~1.6 GH/s Clore (secondary)

The key with all these combinations: Test your actual hashrates and calculate your real solo block odds using the formula from Step 5. Don’t assume that just because you can dual mine two coins, it’s automatically profitable or worth the complexity.

Monitoring and Maintenance for Long-Term Dual Mining

Once you’ve got your dual mining solo setup running stable, you need to monitor it regularly. I check my rigs at least once a day, and I have remote monitoring set up so I can check from my phone.

What to Monitor Daily:

• Hashrate stability: Both miners should maintain consistent hashrate within 2-3% variance
• Temperature trends: If temps are climbing over time, you might have dust buildup or thermal paste degradation
• Rejected shares: Should be under 1% for both miners; higher rejection rates indicate connectivity issues or overclock instability
• Power draw: Use a power meter to verify your rig is pulling expected wattage

Weekly Maintenance:

• Check Public-Pool.io stats for both coins to verify your wallet addresses are correct
• Review network hashrate changes — if network difficulty spikes, your solo odds drop proportionally
• Verify your OS hasn’t auto-updated and broken your miner configurations (Windows Update is notorious for this)

Monthly Maintenance:

• Clean dust filters and fans
• Check GPU temps under load — if they’ve crept up 5°C+ from your baseline, you probably need to clean the heatsink or replace thermal paste
• Review your actual earnings versus expected earnings to see if you’re on track or experiencing bad luck variance

I use a simple spreadsheet to track my blocks found per month, actual earnings, electricity costs, and net profit. After six months of dual mining data, I can see that my actual block finding rate is within about 8% of the statistical expectation — some months luckier, some months unlucky, but it averages out over time.

No joke: The longest I’ve gone without finding any block on either coin was 19 days. That was brutal. But then I hit three blocks in four days and came out ahead. That’s solo mining variance for you.

FAQ: Dual Mining Solo Setup

Can you dual mine with ASICs?

No, ASICs are purpose-built for one specific algorithm and cannot dual mine. Dual mining is exclusive to GPUs because GPUs have separate compute cores and memory controllers that can handle different tasks simultaneously. If you’re solo mining Bitcoin with something like a WhatsMiner M60, you’re locked into SHA-256 only.

Does dual mining reduce the lifespan of my GPU?

Potentially yes, because you’re running your GPU at higher utilization and temperatures than single-algorithm mining. The main wear factors are: higher sustained temperatures (stresses silicon and solder joints), fans running faster (bearing wear), and higher power draw (stresses VRMs). In my experience, a well-cooled GPU running dual mining 24/7 lasts about the same as a gaming GPU used heavily — expect 3-5 years before you might need to replace fans or deal with artifacts. Keep temps under 70°C core and 85°C VRAM and you’ll be fine.

Is dual mining solo more profitable than pool mining one coin?

It depends entirely on your hashrate, electricity cost, and variance tolerance. With my setup (~1.85 GH/s Alephium + 185 MH/s Kaspa), I earn roughly $10-15 more per month compared to pool mining just Alephium, but with huge variance — some months I’m up $40, other months I’m down $20. If you need consistent daily income, pool mining one coin is better. If you can handle variance and mine for fun, dual mining solo is more exciting and potentially more profitable over the long term.

What happens if I find two blocks at the exact same time?

Realistically this will never happen because the two algorithms work independently and blocks are found at different timestamps. Your primary miner might submit a share that becomes a block for Coin A at 14:23:45, while your secondary miner finds a block for Coin B at 14:23:52. The solo pool handles each submission separately and credits your wallet independently for each coin. There’s no conflict because you’re mining two different blockchains simultaneously.

Can I dual mine three coins at once?

Technically yes, but practically no. I tried running three miners simultaneously (Alephium + Kaspa + a third coin on SHA256d) and my primary coin hashrate dropped to about 70% of normal while the secondary and tertiary coins also suffered. The performance tradeoff isn’t worth it. Your GPU only has so many execution units, and trying to split resources three ways means all three coins suffer. Stick to two coins maximum — one primary (90-95% normal hashrate) and one secondary (20-30% of what you’d get single mining that coin).
