Complete Guide: Solo Mining Monero with CPU and GPU 2026

You Want to Mine Monero, But Don’t Know Where to Start?

Here’s the thing: Most mining guides throw you into pool mining because it’s “safer.” Predictable daily payouts, no surprises. But what if you want to actually find a full block yourself? What if you want that complete $343.84 Monero block reward — minus zero pool fees?

That’s where solo mining comes in.

Monero is honestly one of the most accessible coins for solo miners. Why? Because it uses the RandomX algorithm, which was specifically designed to run on regular CPUs. No expensive ASICs. No massive GPU farms crushing your odds. Just you, your processor, and a fighting chance.

I helped my mom set up Monero solo mining on her old laptop last year. If she could do it (and she still calls the browser “the Google”), you definitely can. The setup took us about 30 minutes, and she’s been running it ever since — mostly just to understand how mining works, but still.

This guide walks you through everything. From downloading the Monero software to pointing your hardware at your own node. We’ll talk realistic odds, power costs, and whether your hardware actually makes sense for solo mining.

Why Solo Mine Monero Instead of Joining a Pool?

Let’s be honest about this.

Pool mining gives you small, regular payouts. Solo mining gives you nothing for weeks or months — and then suddenly the entire block reward when you hit one. For most coins, that’s a terrible trade-off. For Monero, it’s actually reasonable depending on your hashrate.

Quick explanation: Monero’s network hashrate is around 2.5 GH/s (that’s 2,500 MH/s). A decent Ryzen 9 CPU gets you 15-20 KH/s. So yes, you’re competing against the entire network. But blocks come every 2 minutes, and there are no massive ASIC farms dominating like with Bitcoin.

Here’s what you need to understand: If you have 15 KH/s and the network runs at 2.5 GH/s, you have roughly a 1 in 166,667 chance per block. That’s about one block every 231 days statistically. Some solo miners hit blocks in a week. Others wait a year. That’s the lottery aspect.

But when you do hit that block? You get the full reward. Currently around 0.6 XMR per block. At today’s price of $343.84, that’s pretty significant — and you keep it all.

The community aspect is huge too. Joining solo mining Discord communities taught me more about mining in three months than a year of reading articles. People share their block finds, compare hardware, help troubleshoot. It’s genuinely supportive.

Understanding RandomX: Why Monero Loves CPUs

RandomX is Monero’s mining algorithm, and it’s beautifully democratic.

The Monero developers created RandomX specifically to resist ASICs and favor regular consumer CPUs. It uses random code execution and heavy memory requirements — things CPUs handle well but ASICs struggle with. This keeps mining accessible to regular people.

What does this mean for you? Your desktop PC actually has a chance. Your Ryzen or Intel CPU is competitive. Sure, someone with a Threadripper or Ryzen 9 9950X has better odds, but you’re not completely outgunned like you would be solo mining Bitcoin without an ASIC.

Can you use GPUs? Technically yes, but it’s not efficient. RandomX was designed to make GPUs perform poorly compared to CPUs — and it works. A high-end GPU might get 2-3 KH/s while consuming 200W. A good CPU gets 15-20 KH/s at similar power draw. The math is simple.

Beginner tip: Don’t waste time trying to optimize GPU mining for Monero. Use your CPU, or don’t mine Monero. There are better GPU coins for solo mining if that’s your hardware.

Setting Up Your Monero Solo Mining Node

This is where it gets practical.

For solo mining, you need to run your own Monero node. You can’t point your miner at someone else’s node for true solo mining — that would just be pool mining with extra steps. Your node validates blocks, holds the blockchain, and receives your mining submissions.

Here’s what you need before starting:

• About 150 GB free disk space for the blockchain (and growing)
• 8 GB RAM minimum, 16 GB better
• Decent internet connection (you’ll download the entire blockchain)
• Patience — initial sync takes 6-24 hours depending on your connection

Step 1: Download Monero Core

Go to getmonero.org and download the Monero GUI wallet. This includes everything: wallet, node, and mining software. Extract it somewhere permanent — not your Downloads folder, because you’ll run this regularly.

Windows users: Extract to C:Monero or similar. Linux users: /opt/monero works well. Mac users: Applications folder is fine.

Step 2: First Launch and Blockchain Sync

Open the Monero GUI. Create a new wallet or restore an existing one. Write down your seed phrase on paper. Not on your computer. Paper. This is your backup if something happens to your hard drive.

The blockchain sync starts automatically. This downloads every Monero transaction since 2014. It takes time. On a fast connection, maybe 8 hours. On slower internet, overnight or longer. Let it run.

You can use your computer for other things during sync, but mining won’t work until it completes. The bottom of the wallet shows sync progress.

Step 3: Configure Your Node for Solo Mining

Once synced, you need to enable mining access. Go to Settings > Node, and make sure “Local node” is selected. You also need to allow connections to your node’s RPC port.

Advanced users: Edit the monero.conf file (or create one if it doesn’t exist) and add these lines:

• rpc-bind-ip=127.0.0.1
• rpc-bind-port=18081
• confirm-external-bind=1

This lets your mining software talk to your node locally. You’re not opening ports to the internet, just allowing local communication between programs on your computer.

Sounds complicated, but it’s not: You’re basically telling your node “yes, my mining software can talk to you.”

Choosing Hardware for Monero Solo Mining

Let’s talk real numbers.

Not every CPU is worth running for solo mining. Power costs matter. If you’re paying $0.12 per kWh and your CPU pulls 150W while getting 8 KH/s, you need to calculate whether the odds make sense.

Best CPUs for RandomX:

Intel options:

Intel CPUs work, but AMD Ryzen generally delivers better RandomX performance per watt. An Intel i9-12900K gets around 14-16 KH/s but pulls more power. Not terrible, but if you’re buying new hardware specifically for Monero mining, Ryzen makes more sense.

What about older hardware? A Ryzen 5 3600 gets about 7-8 KH/s. That’s low for solo mining odds, but if you already own it and electricity is cheap, why not? The hardware depreciation is already done.

Honest warning time: If you’re buying brand new hardware just to solo mine Monero, your ROI timeline is measured in years, not months. Maybe never if XMR price doesn’t cooperate. This works best if you already own decent hardware or find good deals on used CPUs.

Mining Software Setup and Configuration

Now we connect everything.

You have your node running. You have capable hardware. You need mining software that talks to your node and actually does the mining work. For Monero, XMRig is the standard. It’s open source, well-maintained, and honestly just works.

Installing XMRig:

Download from xmrig.com (always verify you’re on the real site — there are scam copies). Extract the files. You’ll see xmrig.exe (Windows) or just xmrig (Linux/Mac) plus a config.json file.

Windows Defender might flag XMRig as malware. This happens because malware sometimes includes mining software. XMRig itself is legitimate. Add an exception in Windows Security if it gets quarantined.

Configuring for Solo Mining:

Edit config.json with any text editor. You need to change a few key settings:

In the “pools” section, replace everything with:

• “url”: “127.0.0.1:18081”
• “user”: “YOUR_MONERO_WALLET_ADDRESS”
• “pass”: “”
• “daemon”: true

That “daemon”: true line is critical. It tells XMRig you’re mining to a local node, not a pool. Without this, it won’t work.

Your wallet address is the receiving address from your Monero GUI wallet. Copy it exactly — one wrong character and you’d lose a block reward if you found one. Triple-check it.

Starting Your Miner:

Save config.json. Double-click xmrig.exe (Windows) or run ./xmrig in terminal (Linux/Mac). You should see colorful text showing your CPU cores spinning up, displaying your hashrate, and confirming connection to your daemon.

Typical output looks like: “READY threads 16/16 (16) huge pages 100% memory 4.0 GB”

Your hashrate shows in real-time. It fluctuates slightly, that’s normal. Check the average over a few minutes for your actual rate.

Optimizing Performance: Huge Pages and CPU Tuning

Out of the box, you’re probably getting 70-80% of your CPU’s potential. A few tweaks can push that to 95-100%.

Enable Huge Pages (Windows):

Huge pages significantly improve RandomX performance. On Windows, you need admin rights. Run Command Prompt as Administrator and type: bcdedit /set increaseuserva 3072 then restart your computer.

This allocates large memory pages for mining software. Performance increase is typically 10-20% hashrate with no additional power draw. Absolutely worth doing.

Linux users: It’s easier. Add vm.nr_hugepages=1280 to /etc/sysctl.conf and run sysctl -p. Done.

Thread Configuration:

XMRig auto-detects CPU threads, but manual tuning sometimes helps. In config.json, find the “cpu” section. The “rx” array controls RandomX thread behavior.

For most modern Ryzen CPUs: Use all physical cores, not hyperthreads. If you have a 16-core CPU (32 threads), configure for 16 mining threads, not 32. RandomX performs better this way.

My Ryzen 9 5950X gained 2 KH/s just from switching to 16 threads instead of auto-32. Your results depend on your specific CPU, but it’s worth testing.

Power and Temperature:

Mining hammers your CPU at 100% load constantly. Cooling matters. If your CPU hits thermal throttling (usually 85-95°C depending on model), your hashrate drops.

Check temperatures with HWiNFO or similar. If you’re thermal throttling, you need better cooling or lower power limits. Some miners undervolt their CPUs slightly — same hashrate, lower temps and power draw.

Beginner tip: Don’t overclock for Monero mining. The performance gain is minimal, but heat and instability increase significantly. Stock settings with good cooling is the sweet spot.

Realistic Expectations: Your Solo Mining Odds

Let’s do the math together.

Say you’re running a Ryzen 9 5950X at 20 KH/s. Monero network hashrate is 2.5 GH/s. Blocks come every 2 minutes (720 per day).

Your odds per block: 20 KH/s ÷ 2,500,000 KH/s = 0.000008 or 0.0008%

Expected time to block: 2,500,000 ÷ 20 = 125,000 blocks = 173 days

That’s the statistical average. Reality is messier. You might find a block in two weeks. You might wait a year. Solo mining is genuinely random — past performance doesn’t influence future odds.

Some solo miners run multiple rigs to improve odds. Three Ryzen 9 systems at 20 KH/s each = 60 KH/s total = one block every 58 days on average. Better odds, but triple the hardware investment and power costs.

Power Cost Reality Check:

Your Ryzen 9 5950X pulls about 140W during mining (the TDP is 105W, but real-world mining load is higher). That’s 3.36 kWh per day, or about 101 kWh monthly.

At $0.12 per kWh, that’s $12 monthly in electricity. Over six months (roughly your expected block time), that’s $72 in power costs. The block reward is currently 0.6 XMR worth $343.84.

Do that math for your local electricity rate and current XMR price. If power costs approach or exceed expected block reward value, solo mining doesn’t make financial sense — though some people do it anyway for the learning experience or because they believe XMR will increase in value.

Honestly, if your electricity costs more than $0.15 per kWh, solo mining most coins becomes questionable unless you have really high hashrate. The numbers just don’t work out.

Monitoring Your Mining: What to Watch

You can’t just set it and forget it. Well, you can, but you should occasionally check that everything runs smoothly.

Check Your Hashrate:

XMRig displays current hashrate in its console. This should stay consistent. If it suddenly drops 50%, something’s wrong — maybe thermal throttling, maybe Windows Update running in background.

Your wallet won’t show pending balance like pool mining does. That’s normal. You only see something when you actually find a block. That moment when your wallet updates with +0.6 XMR is incredibly satisfying.

Node Connection Status:

Make sure XMRig shows “daemon/127.0.0.1:18081 algo rx/0” or similar. If it says “no active pools, stop mining” your node connection died. Restart the Monero daemon.

Your node needs to stay synced. If it falls behind, your mining submissions work on outdated blockchain data and won’t count. The Monero GUI shows sync status at the bottom.

What About Pool Solo Mining?

Some pools offer “solo mining mode” where you mine through their infrastructure but keep full block rewards if you find one. Services like MoneroOcean or similar support this.

Is it true solo mining? Not really. You’re trusting the pool to actually pay you if you find a block. The transparency isn’t the same as running your own node. But it eliminates the need to run a full node yourself, which saves disk space and setup complexity.

For absolute beginners, pool solo mode isn’t a bad starting point. Just understand that real solo mining means your own node.

Security: Protecting Your Block Rewards

If you find a block, that’s potentially thousands of dollars hitting your wallet. Security becomes important.

Don’t keep large amounts in your hot wallet (the one on your mining computer). When you find a block, transfer most of it to cold storage — a hardware wallet or paper wallet that never touches the internet.

Your seed phrase is everything. If someone gets it, they own your Monero. Write it on paper, store it securely, never type it into any website or app asking for it. Legitimate Monero software never asks for your seed except during wallet restoration.

Keep your mining computer reasonably secure too. Basic stuff: Don’t download sketchy software, keep Windows/Linux updated, use decent antivirus. You don’t need Fort Knox security, but don’t be careless either.

Common Problems and Solutions

My hashrate is way lower than expected:

Usually huge pages aren’t enabled, or you’re running too many threads. Check XMRig’s startup text — it tells you if huge pages failed. Also check CPU temperature — thermal throttling tanks performance.

XMRig says “no active pools”:

Your Monero daemon isn’t running or isn’t accepting connections. Make sure the Monero GUI wallet is open and fully synced. Check that config.json has the correct RPC port (18081 is default).

I’ve been mining for weeks and found nothing:

Welcome to solo mining. That’s normal. Check solo mining calculators for realistic timeframes. If your expected block time is 6 months, three weeks is nothing. Variance is huge with solo mining.

My electricity bill doubled:

Yeah, that happens. Mining uses a lot of power. Calculate your CPU’s wattage × hours run × your electricity rate. If it’s too expensive, you need cheaper power, more efficient hardware, or different coin selection.

Windows Defender keeps deleting XMRig:

Add a folder exception for wherever you extracted XMRig. Go to Windows Security > Virus & threat protection > Manage settings > Exclusions > Add folder. Choose your XMRig directory.

Is Solo Mining Monero Worth It in 2026?

Here’s my honest take.

Financially? That naturally depends on your setup. If you already own a high-end Ryzen CPU that you use for other things (gaming, work) and can mine when idle, the additional cost is just electricity. That’s maybe $10-15 monthly. For the chance at a $343.84 block? Reasonable gamble.

If you’re buying hardware specifically to solo mine Monero, the math is tougher. A new Ryzen 9 5950X costs $400-500. At 20 KH/s with current difficulty, you’d expect one block every 5-6 months. That’s 0.6 XMR per block, so roughly 1.2-1.4 XMR yearly. Subtract electricity. Calculate based on current prices whether that payback period makes sense to you.

For learning? Absolutely worth it. Running your own node, understanding how blockchain validation works, experiencing the lottery aspect of mining — you can’t really learn this from articles alone. The practical experience is valuable.

The community is the most valuable thing about mining. Seriously. Joining Discord communities where people share their setups, block finds, optimization tips — that’s where real learning happens. My mom still asks me questions about mining, and I learn new things helping her troubleshoot.

Don’t expect to get rich. Some lucky solo miners find multiple blocks in a month. Others wait a year between blocks. If you need consistent income, pool mine. If you want to understand mining at a deeper level and don’t mind the lottery aspect, solo mining Monero is one of the best entry points.

It’s actually pretty practical: You don’t need expensive hardware, the setup process teaches you real technical skills, and the RandomX algorithm keeps mining democratized. That last part matters — Monero resists centralization better than most coins.

Alternative Approaches: Dual Mining and Diversification

Some miners run dual mining setups — CPU mining Monero while GPU mining something else like Ethereum Classic or Ergo. This maximizes hardware utilization and spreads your odds across multiple coins.

If you have a decent GPU sitting idle while your CPU mines Monero, consider pointing it at Ergo or Flux for solo mining. Different algorithms, different odds, but you’re essentially doubling your lottery tickets.

The setup is straightforward: Run XMRig for CPU mining Monero, run a separate miner like GMiner for GPU work on another coin. They don’t conflict because they use different hardware.

This approach works especially well if you already have gaming hardware. Mine Monero on CPU overnight, game during day, solo mine GPU coins when you’re at work. Maximize that hardware investment.

Frequently Asked Questions

Can I solo mine Monero with a laptop?

Technically yes, but it’s not ideal. Laptops have cooling limitations, and sustained 100% CPU load will either thermal throttle (reducing your hashrate) or potentially damage components over time. If you do try it, use an older laptop you don’t mind stressing, enable power limits in BIOS to cap CPU wattage, and monitor temperatures closely. My mom’s laptop experiment worked because it’s just a hobby for her — she runs it maybe 6 hours a day, not 24/7.

How much can I realistically earn solo mining Monero with a Ryzen 7 5800X?

A Ryzen 7 5800X gets roughly 13-15 KH/s, which at current network difficulty means one block every 185-230 days statistically. That’s 0.6 XMR every 6-8 months, worth $343.84 currently. Subtract electricity costs (around $10-12 monthly at $0.12 per kWh), and your net is maybe $200-300 annually if you run 24/7. But remember — variance is huge. You might hit two blocks in three months, or wait a full year for one.

Do I need to keep my computer running 24/7 for solo mining?

Not necessarily, but it improves your odds proportionally. If you mine 12 hours per day instead of 24, you halve your chances. Solo mining is purely random per hash submitted — past hashes don’t improve future odds. Some people mine only during off-peak electricity hours to reduce costs. Others run continuously because the hardware depreciation is happening anyway. Your choice based on electricity costs and risk tolerance.

What happens if I find a block but my node was slightly out of sync?

If your node is behind by more than a few blocks, your mined block won’t be accepted by the network — it’s building on outdated blockchain data. This is called an orphan block. You did the work, found a valid solution, but it doesn’t count because it’s not building on the current chain tip. This is why keeping your node fully synced is critical. The Monero GUI shows sync status at the bottom — make sure it says “Synchronized” before mining.

Is solo mining Monero anonymous?

Sort of. Monero transactions are private — the blockchain doesn’t reveal sender, receiver, or amounts. But your IP address is visible when your node broadcasts a found block. For most people, this doesn’t matter. If you’re concerned about privacy, run your node through Tor or a VPN. Also remember that block rewards are transparent in your local wallet — anyone with access to your computer could see them. Monero provides network privacy, but your local security is your responsibility.
