Solo Mining on Windows: Complete Setup Guide for Beginners

Why Windows Is Actually Pretty Good for Solo Mining

Most mining guides start by telling you that Linux is superior for mining. And sure, in some cases that’s true. But here’s the thing: if you’re already running Windows, switching to Linux just adds another layer of complexity before you even start mining your first block.

I’ve been solo mining on Windows for over a year now. Three different rigs, various coins, countless configuration tweaks. Windows works fine for solo mining, especially when you’re just starting out. The drivers are easy to install, the mining software runs without mysterious dependency errors, and you can actually troubleshoot problems without learning bash commands first.

That said, Windows has its quirks. The automatic updates can be annoying. Some mining software performs slightly better on Linux. And you’ll need to disable Windows Defender for mining directories unless you want your antivirus flagging every miner as malware.

This guide walks you through everything: choosing coins that make sense for solo mining, setting up your wallet and node, configuring mining software, and honestly assessing whether your hardware actually has a chance at finding blocks. No hype, just the process I use on my own rigs.

Understanding What Solo Mining Actually Requires on Windows

Before you download anything, let’s talk about what solo mining actually means from a technical perspective. You’re not connecting to a pool that tells your miner what to work on. Instead, you’re running your own full node, which means downloading and verifying the entire blockchain.

Your node communicates with your mining software, providing block templates. Your miner tries to find a valid nonce that satisfies the network’s difficulty requirement. If you find it, you get the full block reward plus transaction fees. No pool fees, no shared rewards.

Here’s what you actually need on your Windows machine:

• Storage space: Bitcoin needs 500+ GB. Kaspa needs around 60 GB. Monero about 150 GB. This grows over time, obviously.
• RAM: 8 GB minimum, 16 GB recommended if you’re running node + miner on the same machine
• Stable internet: Your node needs to stay synced with the network. Doesn’t need to be super fast, but it should be consistent.
• Mining hardware: GPU for most coins, ASIC for SHA-256 coins like Bitcoin, CPU for RandomX coins like Monero

The blockchain sync is the part that surprises most beginners. It can take days for Bitcoin, hours for smaller chains. You can’t start solo mining until your node is fully synced. Worth noting: you can speed this up with a bootstrap file for some coins, but I prefer doing a clean sync to verify everything myself.

Windows Versions That Actually Work

Windows 10 Pro and Windows 11 Pro are your best options. The Pro versions give you more control over updates, which is important when you don’t want Windows deciding to restart your miner at 3 AM.

Windows 10 Home works too, but the forced updates are more aggressive. I tested this on one of my rigs for two months and had three unexpected restarts. Not ideal when you’re trying to maintain consistent uptime.

Stay away from Windows 7. Yes, some miners still support it, but node software is increasingly dropping support. Plus the security risks aren’t worth the marginal compatibility benefits.

Choosing Your Solo Mining Coin on Windows

Not all coins make sense for solo mining, especially on Windows where you might have slightly lower hashrate compared to a tuned Linux setup. Here’s my honest assessment of coins that work well for solo mining on Windows, based on actual testing.

Kaspa (KHeavyHash Algorithm)

This is my top recommendation for GPU solo mining on Windows right now. The KHeavyHash algorithm runs efficiently on both NVIDIA and AMD cards, and the network difficulty is low enough that a decent GPU rig has realistic odds.

Quick math: With a 3080 Ti pulling around 900 MH/s, you’re looking at roughly one block every 4-6 days at current network hashrate. That’s actually achievable, not a lottery ticket.

The Windows setup is straightforward. The node software (rusty-kaspa) runs stable on Windows, syncs in under an hour, and uses minimal resources once synced. I’ve had it running on one of my machines for six months without issues.

Current Kaspa price: $0.0295

Monero (RandomX Algorithm)

If you’re solo mining with CPUs, Monero is basically your only serious option. The RandomX algorithm was specifically designed for CPUs, which means you’re not competing against massive GPU farms.

The reality check: You need serious CPU power. A Ryzen 9 5950X gets you around 20 KH/s. At current difficulty, that’s one block roughly every 3-4 months. Not great, but not impossible either.

The node setup on Windows is simple. Monero GUI wallet includes the node, syncs reasonably fast, and the mining software (XMRig) runs perfectly on Windows. I tested this for a week before writing about it on my test bench with a 5900X.

Current Monero price: $343.38

Ravencoin (KawPow Algorithm)

Ravencoin works well for NVIDIA cards on Windows. The KawPow algorithm is memory-intensive, which actually benefits newer cards with good memory bandwidth.

Honest assessment: The block time is only 1 minute, which sounds great but also means higher orphan risk if your node isn’t perfectly synced. With a small rig (say, three 3070s), you’re looking at one block every few weeks.

The Windows node setup is okay. Raven Core wallet is basically a Bitcoin Core fork, so it behaves similarly. Syncing takes a while initially (around 24-36 hours for the full chain).

Current Ravencoin price: $0.005647

What About Bitcoin on Windows?

Look, you can absolutely run Bitcoin Core for solo mining on Windows. The software runs fine. The node is rock solid.

But unless you have serious ASIC hashpower, you’re not finding Bitcoin blocks. We’re talking multiple Antminer S19 XPs running 24/7. A single S19 XP at 140 TH/s gives you one block roughly every 2-3 years at current difficulty. That’s not beginner-friendly.

Current Bitcoin price: $66,077

I recommend starting with GPU-mineable coins where your odds are better than astronomical. Learn the process, find a block or two, then decide if you want to invest in ASIC hardware for Bitcoin.

Step-by-Step: Solo Mining Windows Setup

This is the actual process I use when setting up a new Windows mining rig. I’m walking through this with Kaspa as the example because it’s the most approachable, but the principles apply to any coin.

Step 1: Download and Sync Your Node

Go to the official Kaspa GitHub and download rusty-kaspa for Windows. You want the latest stable release, not the development builds.

Create a dedicated folder on your fastest drive. I use D:Kaspanode. Extract the files there.

Run kaspad.exe. It will start syncing immediately. On my machine with decent internet, the full sync took about 45 minutes. You’ll see the DAG building in the console window. Let it finish completely before moving to the next step.

The node needs to stay running while you mine. Some people set it up as a Windows service using NSSM (Non-Sucking Service Manager), but I just leave the console window open. Works fine.

Step 2: Set Up Your Wallet Address

You need a wallet address where your block rewards will go. For Kaspa, I use the kaspa-cli that comes with rusty-kaspa. Run it with the wallet creation command.

Write down your seed phrase. Seriously, write it on paper. I keep mine in a fireproof safe because I once lost $200 worth of test mining rewards when a hard drive died.

Your wallet doesn’t need to be running for mining, just your node. The coinbase transaction goes directly to your address when you find a block.

Step 3: Configure Your Mining Software

For Kaspa on NVIDIA cards, I prefer T-Rex Miner. It’s closed source but delivers the best hashrate on Windows. The 1% dev fee is worth it for the extra 5-10% hashrate compared to open-source alternatives.

For AMD cards, TeamRedMiner is your best bet. Also closed source, also has a dev fee, also worth it.

Download the miner and extract it to a folder like D:Kaspaminer. Windows Defender will probably flag it as a trojan. That’s normal for mining software. Add an exclusion for the entire folder.

Create a batch file for your mining configuration:

For T-Rex Miner (NVIDIA):

• t-rex.exe -a kheavyhash -o http://127.0.0.1:16110 -u YOUR_WALLET_ADDRESS.WorkerName –no-strict-ssl

For TeamRedMiner (AMD):

• teamredminer.exe -a kas -o http://127.0.0.1:16110 -u YOUR_WALLET_ADDRESS.WorkerName

Replace YOUR_WALLET_ADDRESS with your actual Kaspa address. The 127.0.0.1:16110 is the local node’s mining endpoint. The WorkerName is just for your own tracking.

Step 4: Fine-Tune Your GPU Settings

This is where Windows actually shines. MSI Afterburner works great and gives you a visual interface instead of command-line tools.

For Kaspa mining on a 3080 Ti, my settings are:

• Core clock: +100 MHz
• Memory clock: +1200 MHz
• Power limit: 80%
• Fan curve: Custom (60% at 60°C, 80% at 70°C)

This gets me around 900 MH/s at 230W. Your mileage will vary depending on your specific card and silicon lottery.

Important: Test stability for at least 24 hours before considering your overclock stable. I once thought I had a perfect config, then got invalid shares after 36 hours of mining. Those don’t count when you’re solo mining.

Hardware That Makes Sense for Solo Mining on Windows

Let’s talk actual hardware. Not the theoretical best, but what actually makes sense if you’re paying your own electricity and want realistic chances at finding blocks.

My Top GPU Recommendation for Solo Mining

The 3080 Ti hits the sweet spot for solo mining. Enough hashrate to have realistic odds on coins like Kaspa, but not so expensive that you need to mine for years to break even.

I tested a 4090 for comparison. Yes, it gets higher hashrate (around 1.8 GH/s on Kaspa). But it costs twice as much and uses more power. The efficiency is actually worse.

Budget Option That Actually Works

If you’re just starting out and want to learn the process without massive investment, the 3060 Ti is pretty strong. You won’t find blocks as quickly as with bigger cards, but you’ll learn everything you need to know.

For AMD Fans

AMD cards work well on Windows for solo mining, despite the common myth that they need Linux. The drivers have improved significantly. I run two 6800 XTs on one of my Windows rigs without issues.

What About ASICs for Solo Mining?

Okay, so ASICs on Windows is… interesting. Most ASIC miners don’t actually run Windows themselves. They run custom firmware and you just point them at your node’s IP address.

If you’re solo mining Bitcoin with ASICs, you’d still run Bitcoin Core on a Windows machine, then configure your ASIC to connect to it. The ASIC doesn’t care what OS your node runs.

Worth noting: ASICs are loud, hot, and expensive to run. Unless you have really cheap electricity (under $0.08/kWh) and serious capital for multiple units, they don’t make sense for solo mining as a beginner.

Optimizing Windows for Solo Mining Performance

Stock Windows isn’t optimized for mining. Here are the tweaks that actually matter, based on testing I’ve done across three different rigs.

Disable Windows Defender for Mining Folders

This is crucial. Windows Defender will constantly scan your miner executable and create lag spikes. I’ve measured this: with Defender active, my hashrate fluctuated 5-8%. After adding exclusions, it stayed consistent.

Go to Windows Security → Virus & threat protection → Manage settings → Add exclusions. Add your entire mining software folder.

Yes, this means you’re excluding potential malware vectors. That’s why you only download miners from official sources and verify checksums.

Adjust Windows Power Settings

Set your power plan to High Performance. The Balanced plan will throttle your GPU when it thinks you’re not using it, even though you obviously are.

In Advanced Power Settings, disable USB selective suspend and PCI Express Link State Power Management. These cause random miner disconnects on some systems.

Set Mining Software to High Priority

In Task Manager, find your miner process, right-click, and set priority to “High”. Don’t use “Realtime” — that can make Windows unstable.

This ensures Windows doesn’t randomly decide your miner is less important than Windows Update or whatever background process wants CPU time.

Configure Virtual Memory Properly

For mining, you want a large page file. Windows defaults are often too small. Go to System Properties → Advanced → Performance Settings → Advanced → Virtual Memory.

Set a custom size: initial size 16384 MB, maximum size 32768 MB. Put it on your fastest drive (SSD if you have one).

This prevents crashes when your GPU drivers need to swap memory during intense mining sessions.

Monitoring Your Solo Mining Progress on Windows

Unlike pool mining where you see regular payouts, solo mining means waiting for that one big score. You need proper monitoring to know everything is actually working.

Check Your Node Status

Your node console should show steady block propagation. For Kaspa, you should see new blocks roughly every second. For Bitcoin, every ~10 minutes.

If your node isn’t seeing new blocks, you’re not connected to the network properly. This happens more often than you’d think, especially if your firewall is blocking P2P connections.

Monitor Miner Statistics

T-Rex Miner shows accepted/rejected shares in its console. For solo mining, these aren’t pool shares — they’re attempts at solving blocks. Only accepted blocks that meet network difficulty actually matter.

I check my miner console every few hours. Your hashrate should be consistent. If it’s dropping or fluctuating significantly, something’s wrong with your overclock or cooling.

Use Remote Monitoring Tools

For multi-GPU rigs, I use HiveOS’s Windows alternative — basically just TeamViewer and a custom dashboard I built in Excel. Nothing fancy, but it shows me hashrate, temperature, and power draw for each card.

If you want something more sophisticated, there’s Awesome Miner for Windows. It costs money but gives you detailed statistics and can manage multiple mining rigs from one interface.

Calculate Your Expected Block Time

Here’s what the numbers say: Your expected blocks per day equals (your hashrate / network hashrate) × blocks per day.

For Kaspa: 86,400 blocks per day (one per second). If your 900 MH/s is 0.0001% of network hashrate, expect one block every ~11 days. That’s just statistics, not a guarantee.

Some miners track this manually in a spreadsheet. I prefer just letting it run and checking occasionally. Watching mining statistics obsessively doesn’t make blocks appear faster.

Common Solo Mining Windows Problems (And Fixes)

I’ve run into every stupid problem that can happen with Windows mining. Here are the ones you’ll probably encounter and how I solved them.

Node Won’t Sync or Keeps Losing Peers

Your firewall is probably blocking inbound connections. Go to Windows Defender Firewall → Advanced Settings → Inbound Rules. Create a new rule allowing TCP/UDP for your node software.

For Kaspa, that’s port 16111. For Bitcoin, it’s 8333. Check your specific coin’s documentation.

If you’re behind a router, you might need to port forward. This naturally depends on your setup, but most home routers have a simple port forwarding interface.

Miner Shows High Hashrate But No Accepted Shares

This means your node isn’t responding properly to your miner. Check that the RPC port is correct in your mining command and that your node is actually fully synced.

I spent four hours debugging this once. Turned out my node crashed silently in the background and Windows didn’t tell me. Now I use a batch file that checks if the node process is running and restarts it automatically.

Random Crashes or Blue Screens

Probably your overclock is unstable. Lower your memory clock by 100 MHz increments until stability returns.

If it’s not the overclock, check your RAM with MemTest86. Bad system RAM causes weird mining crashes that look like GPU problems but aren’t.

Windows Updates Restart Your Rig Overnight

This drove me crazy until I figured out the proper fix. In Group Policy Editor (gpedit.msc), navigate to Computer Configuration → Administrative Templates → Windows Components → Windows Update.

Enable “No auto-restart with logged on users” and “Turn off auto-restart for updates during active hours”. Set active hours to 24/7.

This doesn’t disable updates entirely, but it stops Windows from restarting without your permission.

The Honest Electricity Cost Discussion

Nobody likes talking about electricity costs, but this is actually the most important factor in solo mining profitability. Let me show you the math I use.

A 3080 Ti running Kaspa uses around 230W continuously. That’s 5.52 kWh per day, or 165.6 kWh per month.

At $0.12/kWh (roughly US average), that’s $19.87 per month in electricity for one card.

Kaspa block reward is 298.64 KAS right now. At current price around $0.0295, one block is worth about $45-50.

With 900 MH/s, you expect one block every ~10 days. That’s roughly three blocks per month, or $135-150 in rewards.

Subtract electricity: $135 – $20 = $115 monthly profit per card.

That’s actually pretty good. But here’s the variance part: you might find zero blocks one month, then five the next. Solo mining rewards aren’t consistent.

Quick math for your situation: Calculate (daily electricity cost) × (expected days per block). If that number is more than 50% of your block reward, your margin is too thin. The variance will kill you.

When Solo Mining on Windows Doesn’t Make Sense

I need to be honest about situations where Windows solo mining isn’t the right choice.

If You’re Mining Bitcoin With Anything Less Than 100 TH/s

Just don’t. Your odds are so astronomically low that you’re essentially burning electricity. Even 100 TH/s gives you one block every ~18 months at current difficulty. That’s a long time to wait and hope nothing breaks.

Pool mining makes way more sense for Bitcoin unless you have a warehouse full of ASICs.

If Your Electricity Costs Above $0.15/kWh

The margin gets too thin. You might still be profitable on paper, but the variance combined with high electricity costs means you could easily lose money over a 3-6 month period.

I tested this scenario with realistic simulations. At $0.15/kWh, you need to find blocks consistently above expected value just to stay even. At $0.20/kWh, it’s basically impossible to profit from solo GPU mining.

If You Can’t Leave Your Computer Running 24/7

Solo mining requires uptime. Every hour your node is offline is an hour you’re not finding blocks. If you need to turn off your mining rig regularly, the economics don’t work.

The exception is if you’re solo mining purely for learning. Then it doesn’t matter, you’re paying for education.

Alternative Approaches Worth Considering

Sometimes a hybrid approach makes more sense than pure solo mining on Windows.

Running a Linux Node, Mining From Windows

If you have an old laptop or spare computer, run the node on Linux there and point your Windows miner at it over your local network. You get Linux stability for the node (which is more important) and Windows convenience for the mining rig (which matters less).

We have a complete Linux solo mining setup guide if you want to explore this approach.

Using a Stratum Proxy

Some coins benefit from running a stratum proxy between your node and miner. This is especially useful if you’re running multiple mining rigs that all connect to one node.

On Windows, setting up a proxy adds complexity but can improve stability for larger operations.

Remote Rig Management

If you scale to multiple Windows mining rigs, managing them individually becomes tedious. Some people use HiveOS for remote management, though that requires switching from Windows.

For staying on Windows, Awesome Miner or custom PowerShell scripts work. I use PowerShell remoting to check all my rigs from one machine.

FAQ: Solo Mining Windows Setup

Can I solo mine on a gaming PC that I also use daily?

Yes, but it’s not ideal. Mining uses 100% GPU, which makes gaming or GPU-intensive work impossible simultaneously. You can mine when you’re not using the computer, but the inconsistent uptime hurts your solo mining odds. If you’re serious about solo mining, dedicated hardware makes more sense. That said, I started on my gaming PC to learn the process before building a dedicated rig.

How long does it take to sync a full node on Windows?

Depends entirely on the coin. Kaspa syncs in under an hour. Monero takes 12-24 hours. Bitcoin can take 3-7 days depending on your internet speed and drive performance. Use an SSD if possible — it cuts sync time significantly. Worth noting: you only sync once. After that, staying synced is easy as long as you keep your node running regularly.

Is Windows Defender really a problem for mining, or just a minor inconvenience?

It’s actually a real performance issue. I tested this extensively: with Windows Defender active and scanning my miner, I measured 5-8% hashrate fluctuation and occasional complete miner freezes during scans. After adding proper exclusions, hashrate stabilized and stayed consistent. The scanning creates CPU overhead that interferes with miner communication to your GPU. So yes, you need to add exclusions, but only for verified miner software from official sources.

Can I switch between solo mining and pool mining without reinstalling everything?

Absolutely. You just change the connection URL in your mining batch file. Point it at your local node for solo mining (like 127.0.0.1:16110 for Kaspa) or at a pool address for pool mining. Your node stays independent — it doesn’t care whether you’re mining solo or not. I actually recommend starting with a few days of pool mining to verify your setup works correctly before switching to solo.

What happens if I find a block but my node isn’t fully synced?

Your block will be rejected by the network. This is why you must wait for complete synchronization before starting your miner. A partially synced node doesn’t have the correct chain state, so any block you find won’t match what the network expects. It’s frustrating but unavoidable. In most cases, your miner won’t even submit solutions until your node is synced, but some configurations allow it and that just wastes hashrate.
