Generally, it's not worth your time and effort to mine at home! (Some exceptions may apply.) Age of ASIC mining CPU mining has been unprofitable since 2011, GPU mining just slightly later. Today, ASICs rule mining. The Bitcoin network has more than 1.7 Ehash/s (Oct 2016) now which is 1,700,000,000,000 Mhash/s. Your graphics card will be running full ...

Javascript has access to OpenGL ES, including shaders, so it has access to programmable parts of the GPU at nearly native speeds. I think that a smart kid might be able to build a fragment shader that does SHA256 hashing, which outputs to the stencil buffer, so that Javascript has a 2-way communication channel with the GPU. So yeah, you could probably use ...

You're using the wrong hash algorithm for Bitcoin mining. Bitcoin uses SHA256d (d = double), but cpuminer (at least the version 2.3.2 on my system) defaults to scrypt (for Litecoin) instead: -a, --algo=ALGO specify the algorithm to use scrypt scrypt(1024, 1, 1) (default) sha256d SHA-256d Slush's pool ...

There are several options for Mining Bitcoins some of these are no longer profitable, but for the sake of being thorough here they are in order of efficiency lowest to highest: Methods CPU Mining (minerd) GPU Mining (cgminer, bfgminer) FPGA Mining (Custom software - https://github.com/fpgaminer/Open-Source-FPGA-Bitcoin-Miner) ASIC Mining (cgminer, bfgminer,...

Any CPU can still be used to mine Litecoin, although much less effectively as a modern AMD GPU could. Mining with a CPU gives you very bad hashrate therefore I wouldn't recommend it. Even a high end CPU will not give you the hashrate of a mid range GPU. You should use a graphics card (GPU) to mine litecoins or switch to another coin Additional Information:...

It's definitely not against the law. It might be breaking the terms of service (ToS) but there's really no reason why any dedicated server hosting provider wouldn't allow you to max out the CPU. I wouldn't do business with them if they limited that. However, you need to read your hosting provider's ToS. They might forbid certain applications like IRC servers,...

Have you tried understanding why you have that desire? It might help you understand more about what makes you tick. You might like to try mining Litecoins, or even on the Bitcoin Testnet. Or, you could try some Bitcoin mining with the Eligius pool, which from memory will pay out any amount after 2 weeks (whereas most pools have a minimum payout). If you can ...

Can i do mining with a normal PC? Yes, you can. I don't have too many expectations. Maybe 0,1 in one week? No, not possible. You will effectively compete against all computational resources on Earth, that are now cracking this nut. If I can estimate, a humble home PC will produce around 1 - 100 MH/s, based on CPU or GPU mining stats. This range covers ...

I wouldn't suggest to mine with your laptop further more I wouldn't mine with a CPU any more. Your laptop can damage quite fast, because mining is very hardware intensive and it can overheat your components. After some time they will get damaged because they are not build to hold that power over a long period of time. Your hashrate is quite low. With ...

The bitcoin community would have to decide that they don't particularly care about having significant security anymore. ASIC-resistance weakens the security of proof of work chains because it eliminates the need to invest in a chain in order to attack it. Someone who owns lots of expensive ASICs will not want to let them be used to attack the chain they are ...

It would not at all be useful for Bitcoin mining. However, it may be useful for other digital cryptocurrencies, such as Litecoin or PPCoin.

http://blog.brycekerley.net/post/5338746136/bitcoin-mining-on-amazon-ec2 Here its explained at best, that it is NOT profitable even on the GPU servers ;)

Here, a nice explanation (even if the post is old) http://www.righto.com/2014/02/bitcoin-mining-hard-way-algorithms.html

It is likely that neither is profitable for you, because ASIC miners are alot more effective than any GPU mining, which in turn is alot faster than CPU mining. But don't take my word for it. This hardware comparison wiki is a good source to make an initial estimate. There is one entry listing the combination of an A10 and a HD7660G GPU, claiming to get 105 ...

Litecoin is the 2nd most popular currency in the same family as Bitcoin, and: It is based on the Bitcoin protocol but differs from Bitcoin in that it can be efficiently mined with consumer-grade hardware. Litecoin provides faster transaction confirmations (2.5 minutes on average) and uses a memory-hard, scrypt-based mining proof-of-work algorithm to ...

To be honest, you came in a little too late. Mining is now done by ASIC's (Application Specific Integrated Circuit). These are chips (like the ones Intel and AMD make) that are only capable of hashing SHA-256. These chips are very limited (they can't run any other software), but can do what they were made to do extremely fast. An Intel 'universal' CPU can ...

Yes Erik, the mining feature is still built-in and you can check how many hashes your CPU can perform. Although it's pointless and you cannot earn anything, it is still a fun experiment that people like to try. If you have a bitcoin core installed and synced with the network, you can just simply open the command console and type in and enter: setgenerate ...

The official bitcoin client from bitcoin.org has a CPU mining option. Add a file named bitcoin.conf to the bitcoin data directory, with the contents gen=1 https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File


5

You can always try the testnet it is really easy to mine on it since difficulty gets reseted to difficulty one. Just start your bitcoin client with the -testnet parameter (and -gen if you want to CPU mine)

CPU mining is DEAD. GPU mining is DEAD. Even FPGA mining is DEAD ! ASIC's ? Yes them still can be profitable. But..... ONLY if you can get your ASIC cheap. Here are the maximum prices you can pay for ASIC, and still have some hopes to get ROI in 3-4 month: 40+ GHs for 1BTC - if you get your machine TODAY 75+ GH/BTC - if ASIC delivered within 1 month 160+...

If you are after bitcoins I wouldn't even spend time on CPU or GPU. It is now difficult with specialized hardware (butterfly labs, kncminer ... ). You can have a look at cloud mining (cexio) as well it is expensive and you have to have bitcoins already but you can buy and sell GH/s and you can actually make more from trading than mining.

I know this is an old question but recently I got a similar server. I've tested rpcminer, GUI Miner (Which is actually UFASoft miner). Personally the best I've found is CPUMiner. With a hash rate of about 75MH/s, it takes a bit of setting up as CPUMiner is normally used for Litecoin mining. CPUMiner gave me about 10%-20% more than the closest rival, which ...

Yep there are three good options for CPU mining that I know of: XPM: PrimeCoin QRK: Quark PTS: Protoshare - very very new and exactly what you described. Google search those and you'll find plenty of info. Seems like there was a fourth but I can't remember it off the top of my head.

I would highly recommend using Ubuntu Server for this, as long as you know what you are doing without a GUI. Not having a GUI at all means smaller OS size and much less OS tasks. This translates into more power savings. If you are using graphics cards, a non-GUI OS will improve your mining performance. If using an ASIC/etc. you probably will not see ...

Assuming that IsraCoin uses the Scrypt-Hashing algorithm as suggested in the comments on the question, I found this hardware overview table on Litecoin (which also uses Scrypt). The table lists a number of Intel Core i5 processors ranging in hashrate from 12 to 55 kHash/s. I.e. depending on what processor you have exactly and whether IsraCoin uses the same ...

Even on testnet the difficulty is sufficiently high that it will take you a long time to mine anything using cpu. (Lots of people testing ASICs, presumably.) Your best bet is probably Testnet in a box. Then you can cpu mine just by using ´setgenerate true´ in Bitcoin Core.


3

It is possible, but not profitable. Even if you consider the server as already paid for you will not generate nearly enough of a hashrate to earn more than a few cents a month.


3

It's pointless. With that kind of hardware, it would take you on the order of a month to mine a dollar's worth of Bitcoins, and the electricity used would cost you many times that.


3

The original question was [sic] "What is the fastest CPU miner that I could use". Based on the answers, it seems, that everyone by default went to cpuminer/minerd. I use it also. However... bfgminer (all except the latest version) has the ability to be used as a cpu miner. I have not been able to optimize mine yet but I do know that it is an incredibly ...

If you could get recent GPUs (Radeon HD 6850 or newer) for very, very cheap, you might be able to make a couple of Bitcoin per month. It may not be worth it, depending your electricity costs. Use these tools to help guide you to an informed decision: P3 Kill A Watt power meter, to find your actual power consumption Mining hardware comparison, to find a GPU ...
