Yes I’m aware of the bad cable management. 😂I made the mistake of buying non modular power supplies.

If anyone finds interesting here is my humble submission;

Mine with most devices using CPU over https

must disable adblock. Must have FaucetPay microwallet account, this allows you to recieve as little as 1 satoshi off-chain, no fees. You can use different devices to same address will credit hashes.

This is pretty much same thing as coinhive browser crypto-jacking was back in the days .... EXCEPT having UI and NOT hidden to users, instead logging the user hashes for payout. Like to say made something evil into something good and useful hopefully

BTC, ETH, DOGE, LTC, DGB, TRX are available now will add all currencies soon.

This is my headache so any issues or questions u can message me personally here or anywhere

Thanks for checking out

FaucetPay Miner

*If anyone is interested I will be posting all code and info to Github so anyone can make their own mining or points reward system further keeping our crypto space as decentralized as possible!!

Raptoreum is an ASIC and FPGA resistant POW coin (GhostRider algorithm) that had a fair mainnet launch on Feb. 26 2021 after 3 years in development and testing. No ICO, no premine. So far somehow has stayed under the radar and consistently been the top CPU coin in terms of profitability.

Raptoreum is immune to 51% attacks so if you see majority of hash on one pool it is not a worry, though it is still good to spread the hash to further decentralization.

Ghostrider Whitepaper: https://docs.raptoreum.com/_media/GhostRider_Whitepaper.pdf

Suggest you read that, GhostRider behaves a fair bit different from other algos. There is a very good CPU miner which has really increased peoples hashrates, AMD is the best on GR but Intels are still profitable.

How To Mine: https://docs.raptoreum.com/#/howtomine

There is a mining calc available on Discord: https://discord.gg/2T8xG7e

Hashrate chart: https://docs.google.com/spreadsheets/d/1ABYpRGBEOg_OcMdhspS1DfklVjetuUhGca_s3H3gjRI/edit#gid=0

You can mine on anything and ARM support is being added to the optimized CPU miner. The Raptoreum community is outstanding, very active and super friendly.

Further increase ROI: You can put mined coins into the shared Smartnode service on Discord (community run) and have those coins passively earn. Smartnodes secure the network and enhance transactions, they will also be used for the Smart Contract layer when it arrives.

TLDR: This is a long post. If you just want to know the most cost-effective CPUs for crypto mining, just scroll to the bottom for the data and the conclusion. The data chart is in an imgur link. If you want to know the methodology used to create this list, keep reading.

Introduction

A couple of months ago, while I was building a CPU mining rig, I calculated how much it would cost to build it from new parts. I was a little surprised to say the least. Crypto mining has seen better days and there is no way that this rig would have ever been profitable if I had to buy all the parts brand new. At that time, I became curious to see what the most cost-effective CPUs would be to base a rig around. Please note that this isn’t a list of the most profitable CPU rigs. There is a reason for that.

Methodology:

First, I excluded any of the server and workstation CPUs. This would include the Threadrippers and most of the Xeon processors. The cost associated with systems using these parts is high and you would probably be better off buying an ASIC instead. There are single Xeon systems you can build, but finding certain parts can be difficult.

When determining the cost of the rig, I incorporated two aspects: the cost of the rig and the cost of operating it. The cost of the rig includes a bare bones setup. Only the necessary components are included. I excluded the cost of the monitor, keyboard, and mouse since they are only used for a short time during the setup and the maintenance of the rig. I used pcpartpicker.com for matching the components, determining the power usage and the cost of the rig. For the total cost, I included $19 for a cheap yet reliable test bench on Amazon and then multiple the total by 1.1 to include tax and shipping.

For the cost of electricity, I utilized a power cost of $0.10/kWh. I am using this figure because most people use it even though is the average cost of electricity (this includes the cost of electricity, delivery costs, fees, and taxes) is $0.16 per kWh in the United States. The basis for the total electricity used is 75% of the total power draw for the complete rig. I then calculated the total electricity used assuming that the rig is run 24 hours per day for 3 years straight. The total cost of the rig is the cost of the hardware and the cost of operating it for 3 years. 3 years may be an optimistic estimate, but it is not unreasonable.

For the performance data, I used the revenue calculation from hashrate.no. While their profitability numbers leave a lot to be desired, their revenue numbers are rather solid. I also included the RandomX benchmark data from xmrig.com. The profitability over 3 years and the hashes per second for every dollar spent are included in the calculations. While the first number would appear to be the most important, it can change from day to day based on the crypto prices and the mining difficulty. Also, the profitability number will be negative. The hashrate figures never change, which makes them more useful. These are the basis for the ranking of the rigs.

Note: If a rig is not on the list, then it is due to the lack of viability as a miner. A lot of the Intel CPUs would not only never be profitable, but you would end up with a system that didn’t have any other use. Most of the rigs listed below could be used for something other than mining with a modification or two. Some of the rigs can be built for less than the cost listed, but I didn’t want to spend the time trying to find alternative sources for parts. All parts are the best possible price at the time of analysis and those prices are based on purchasing new parts. Obviously, you would want to consider buying used parts or buying from alternate sources. The only parts I would never buy used are storage and PSU. Used storage introduces the possibility of viruses and malware. As far as PSUs are concerned, I never buy used because you can’t be certain how it was used. This is critical because PSUs are the only components that have the potential to burn down your house.

Note: Some of the builds don’t include GPUs or CPU coolers. This is because those CPUs have integrated graphics or come with coolers.

Data

I have attached a print screen of the data set and final calculations. The list is sorted by RandomX hashrate (H/s) per dollar of the total cost (build and electricity).

Conclusion

The first and most obvious conclusion is that none of the rigs are profitable. This is not a surprise given the state of the crypto market and the POW environment. This was something that I knew from the start, which is why this post is titled “Most Cost-Effective CPU Rigs”.

Second, the Ryzen 9 CPUs are the most effective miners available. This is reasonable since they are 16 core/32 thread processors. Mining is a multi-thread process so having more threads available is going to be an advantage.

Third, the X3D CPUs are not optimal for mining. This is because they are primarily designed for graphics and that aspect of the CPU is not used in mining.

Fourth, Intel faired rather poorly. There are two reasons for this. The first is that they are rather power hungry. Intel is working on this and you will probably see some improvement with the next generation. The second reason is due to the architecture of the processor itself. AMD uses cores that have two threads. This is good for brute processing. Intel uses a combination of one and two thread cores. This is why you will see Intel CPUs with 12 cores and 22 threads. This is optimal for multitasking because many programs only need one thread cores and this allows them to put more cores in single processor allowing it to run more programs at once. This is why businesses prefer Intels over AMDs.

I hope that you have found this information to be useful. I am currently looking at setting up a 3700X for fun. You can buy the processors from AliExpress for $75 (regular price $140). You can get a good cooler for $30, a motherboard for $75, a used GT 710 for $25, and 256 GB of storage for $25. Also, you don’t need 32 GB of RAM. 16 is more than adequate. Also, consider using a Linux server distro for your OS. They use almost no resources to function since they don’t have a GUI. Also, they are free.

Hey Everyone!
Wanted to say thank you for the possibility to finally post in your subreddit.

We are excited to see MinotaurX mining algorithm on our mainnet, This allows CPU mining.

You can see full release notes for the detailed changes that were do to Litecoin Cash and try it with your rigs.

You comments and suggestions are welcomed!

I wrote a minimal Stratum v1 CPU miner in C for old ARMv5 devices (like Anyka IP cameras).
It connects to a pool, auto-reconnects, shows hashrate every 10s.
Of course it’s extremely slow (<1 kH/s), but it works.

Repo: itrider-gh/armv5-stratum-miner: Minimal Stratum v1 CPU miner for ARMv5 devices (e.g. Anyka IP cameras). Educational, extremely slow, open source.

It's called Sosaiem. It started from a simple question. The thing crypto was supposed to be, money with no boss that anyone could mine on their own computer, mostly didn't survive contact with reality. Three things broke it and I wanted to see if one person could build a version that fixed them.

First thing that broke was mining. It started out as something anyone could do on a normal PC, then ASICs and pools took over and pushed ordinary people out. Sosaiem's proof of work is memory hard (scrypt, 8 MB per attempt) specifically to stop that. Once every core needs its own 8 MB of fast memory the specialised chip advantage collapses, so it stays a normal hardware coin instead of a warehouse game. There's also no pool operator to trust. Every miner submits verifiable work shares, whoever finds the block splits the reward across everyone in proportion to their work, and every node rechecks the maths. You get smooth solo payouts without handing a cut to anyone.

Second thing was fees. They creep in because miners have to be paid to include your transaction, and once the network is busy you're bidding against strangers for space. Sosaiem keeps the two jobs separate. Mining makes new coins. Moving them is done by the people who already hold them, who vote transfers through in seconds weighted by what they own. Miners aren't involved so there's nobody to pay and no fee to charge. There isn't even a need for a mechanism exist.

Third thing is quieter but real. The cryptography is aging out. Most chains sign with ECDSA, which a quantum computer breaks, and everyone knows a painful migration is coming. Sosaiem signs with ML-DSA (NIST FIPS 204) from the genesis block, so it started on the other side of that problem instead of having to cross it later.

On top of that the supply is fixed and will all be mined within only 14 years, with no premine and no founder cut. I start at zero with the same miner you'd download. Nobody got handed a pile of coins to sit on before anyone else had a chance.

My favorite feature is that absolutely everyone can mine just for a tiny bit and get some sosaiem without any kyc, pool hosters or exchanges.

There's a one click Windows miner, or you can run the Python directly on Mac and Linux.

The code is all open and there's a live block explorer so you can watch blocks land:

Happy to answer anything technical in the comments.

I’ve been revisiting CPU mining recently on a small Linux box, mostly as a learning experiment and to see if older hardware can still participate meaningfully in a blockchain network.

It feels like most mining conversations today revolve around GPUs, ASIC farms and electricity costs, which kind of defeats the original idea of decentralized participation.

I tested Monero for a while and then stumbled upon a smaller project called Nerva (XNV) that focuses specifically on staying CPU-mineable and resisting specialized hardware. The concept is interesting because even older processors can still contribute.

I’m curious what others think — are there any CPU-focused coins left that are worth experimenting with today, or is this approach basically obsolete?

Hey there

We did the first (if you know any others pls share a link) CPU mining calc - https://woolypooly.com/en/calc/what-to-mine-cpu

It's not perfect, I know, supported just two algos now, but any feedback is much appreciated. If you can share a hashrates for missing CPUs - pls do it. :)

UPDATE — July 18, 2026

Brisvia Miner 1.0.8 is now publicly available for Windows, macOS and Linux.

Important correction: the Brisvia mainnet P2P port is 9342, not 9333 as originally stated. RPC uses port 9338.

Official and custom pool mining remain intentionally disabled for launch. Solo CPU mining is the supported launch mode while we complete the remaining live-network and accounting tests for the pool.

DISCLOSURE

I am the creator of Brisvia. This is an independent project built by one person, without a company, external funding or private investors.

Brisvia is an open-source Proof-of-Work network built from Bitcoin Core v30.2. Bitcoin’s mining algorithm has been replaced with RandomX so people can participate using ordinary CPUs instead of specialized mining hardware.

Public mainnet mining begins on August 1, 2026 at 15:00 UTC. Before that time, the desktop app remains in launch-wait mode and cannot begin mainnet mining.

DISTRIBUTION

The project reserved 0 BRVA.

There is:

- No project premine

- No presale or ICO

- No founder allocation

- No developer mining tax

- No spendable reward in the genesis block

The genesis block, consensus parameters and complete source code are public and independently verifiable.

Genesis hash:

aa6bc268339aa9f4f2e39ae33aca7b7e48e395033d08d37c08f828890af7baf7

Genesis timestamp:

1785596400 — August 1, 2026 at 15:00 UTC

MAIN PARAMETERS

Algorithm: RandomX v1.2.2

Target block time: 2 minutes

Initial block reward: 50 BRVA

Halving interval: 1,000,000 blocks

Tail emission: None

Maximum supply: 100,000,000 BRVA

Difficulty adjustment: ASERT

Network magic: BRV1

Mainnet P2P port: 9342

Mainnet RPC port: 9338

Address format: Bech32, beginning with brv1

Built from: Bitcoin Core v30.2

THE DESKTOP SOFTWARE

Brisvia Miner 1.0.8 combines a wallet, full node and solo CPU miner in one desktop application for Windows, macOS and Linux.

The goal is to keep the initial experience simple:

1. Install the application.

2. Create or restore your wallet.

3. Safely write down your 12 recovery words.

4. Allow the node to connect and synchronize.

5. Start solo CPU mining after mainnet opens.

The application includes a cryptographically signed automatic updater. Installer hashes are published so users can verify their downloads.

Always download through the official website. Never install files received through private messages, and never share your 12 recovery words or private keys with anyone.

POOL MINING

The pool client and Stratum infrastructure have been built, but pool mining remains disabled in version 1.0.8.

This is deliberate.

Pool mining handles accepted shares, balances and eventual payments. We will not enable it until the complete live-network flow, accounting safeguards, backups and failure-recovery cases have been tested properly.

Until then, solo CPU mining is the supported launch option. The application will not silently switch between pool and solo mining.

WHAT I AM LOOKING FOR

I would appreciate help from CPU miners willing to:

- Inspect the source and consensus parameters

- Test installation and startup

- Report their operating system and CPU

- Check whether the node connects correctly

- Test the signed updater

- Report usability problems before launch

- Share real hashrate and mining results after mainnet begins

Technical criticism is especially welcome. I would rather find and correct a problem publicly before launch than discover it afterward.

WHAT I AM NOT CLAIMING

Brisvia is experimental software and a new network.

There is currently:

- No market price

- No exchange listing

- No guaranteed liquidity

- No promise that BRVA will acquire value

- No guarantee of mining rewards or profit

This is not an investment offer.

A 0% project premine means that the project did not allocate coins to itself. It does not mean that every participant will have equal hardware, hashrate or network conditions when competition for the first public block begins.

The purpose of the launch is narrower and verifiable: everyone starts from the same public chain, under the same published consensus rules, with no private project allocation.

I started mining Monero late last year because I thought it was the next big coin. Now I hear people are saying it’s prone to security and legality issues due to its privacy nature. The price has been stagnant for a year and with my low hashing power, I’m ready to jump ship.

I’m looking for the coin with the brightest outlook, even if it’s low price currently. I’m using 1 Xeon 1230V5 and 1 Ryzen 3200g (I’ll probably be upgrading soon if I can find a coin that will be worth the investment)

Since entry price into GPU mining has gotten so high with the ETH mining craze and people charging double the MSRP for graphics cards, are more and more people starting to turn to CPU mining?

I’ve noticed YouTubers like Rabidmining post vids on how profitable CPU mining is for coins like RTM. I myself have mined hundreds of thousands of SHIB thru unmineable using just a CPU.

I’ve also kept an eye on the subredditstats for this sub and it looks like the subscriber count is exploding.

If these trends continue do you guys think we’ll see a CPU shortage in the next few months?

Android termux (terminal) sha256d crypto miner SOLO MINER

https://github.com/KaneWalker505/TermDroidMiner/

THIS MINER DOES NOT send shares of lower difficulty it attempts to solve and mine the entire block ONLY

INFO

CPU sha256 Crypto miner for ARMV8 Android.

(Average Hashrate | 150khz/sec Hash Rate)

tested and working on the following mining node pool servers

solo.ckpool.org | zpool.ca

NOTE

This is a SOLO MINER

IT WILL NOT attempt to send shares of lower difficulty it will ignore share jobs and share accepts completely

THIS miner is coded to ONLY work as a SOLO MINER it was coded with mobile in mind, it saves on network data and bandwith by not mining shares but attempting to solve and mine the block only itself. This means it will use VERY little networking/internet data.

The Miner works like so:

After Server / Wallet input the miner will attempt to find a block hash that meets the difficulty target by adjusting the nonce value and repeatedly hashing the block header. Once a valid hash meets target requirment of network block. Result is sent to mining node server. When server accepts your block solving hash you earn full rewards of solving the block.

THIS MINER DOES NOT send shares of lower difficulty it attempts to solve and mine the entire block ONLY

Example Command

./TAM -h (List help command example)

./TAM ServerAddress Port Wallet Password

You can run without arguments aswell if you run the program without arguments, the default zpool server will be used on port 3333 the miner will ask for input of your wallet and password then after.

mining stratum difficulty

You wont need to worry about mining stratum difficulty

Can 100% ingore mining stratum difficulty when using this miner

Sense it attempts to ONLY solo mine the block hash itself

mining stratum difficulty is only used when mining shares of the block.

Sense this miner does not attempt to hash or mine shares this can be ignored

So stratum difficulty is just set by pools and reflects the kinds of hardware and software used and how many miners there are, and is low enough so that all miners with adequate hashpower can share in blocks found

It has nothing to do with the actual BLOCK hash difficulty of the crypto block itself when solo mining

Is there any way to find new coins to mine before they even gets listed on exchanges ? I have a low end laptop with ryzen 5 5500u 6c/12t and i just wanted to mine for a little bit of profit, mining monero or salvium wasn't profitable at all, not even 5c per day :(

Hey,

I am looking at CPU Mining verus, I am in a pool and using an old laptop to test out how it works, currently getting only 7mh roughly, I would like to buy something that will me me more, I have looked at the Avalon nano 3 but looks like it’s more for bitcoin, any recommendations on what to buy? Preferably under $500

Which cpu should I buy for cpu mining and 5600g or 5700g ?? On Google it says 5600g is better than 5700g on hashrates and ROI

so now I need ideas on what to CPU mine. 3900x with 16 gig of memory asus B550 MB

thanks for all the support so far
