I plan on mining litecoins, but I'm somewhat late and new into the game. Would it be better for me to get a video card later, tight on budget?

I'm not sure how to do the math. There isn't any overhead costs; I just want to build and let it run. I can build three rigs, all with 2 x E5 2620 and 32 GB RAM. How much would I produce per day?

  • Can I mine...? Yes. How much...? Build one, see how it goes and multiply by three. – Greg Hewgill Jan 16 '14 at 1:30
  • But I don't know how the hash math thing works. If you can give me an answer for one. I can multiply by 3. :) – user12284 Jan 16 '14 at 1:31
  • See my answer. You will get horrible results. CPU are not made for mining I cannot even get my i7-3770 to mine. I have to have cgminer use my GPU. – Tom Stickel Jan 16 '14 at 3:25
  • The only coins you can mine nowadays using any CPU, no matter how fast, are those using algorithms specifically designed to be GPU- or ASIC- unfriendly, such as primecoin (search of primes), quarkcoin (several hashes in row), etc. Anything else, and you'd only lose money - unless you're doing it just for fun. – Joe Pineda Jan 16 '14 at 21:16

Using a CPU is a bad idea; a GPU is better. Good AMD... The best AMDs are hard to find or impossible to find, but the AMD R9 280x and 290x you can find (second-hand on eBay if you don't see them on Newegg, etc..) Sort the chart by GPU, or in your case CPU, search for your CPU...

I tried to play with mining with an i7-3770, and it wouldn't. I don't have any idea why. I had to tell CGMiner to use my GPU which is NOT an AMD, thus horrible. I could mine Coinye coins, but who cares about that.

The page Mining hardware comparison is great for your question.

  • If an i5 yields about 0.3 Primecoins a week, with an i7 I suspect you could get 50% more. Since you need the whole PC to be on so the GPU can work, the extra cost of putting the CPU at 100% instead of idle would be almost negligible. – Joe Pineda Jan 16 '14 at 21:18
  • i don't advise using CPU, and if a good GPU is being pushed... you NEED to have open rig with fans blowing on them. In a case, you will burn them up. – Tom Stickel Jan 17 '14 at 1:34
  • Primecoins are only mineable with CPU - some experimental GPU miners exist, but they're less productive (and thus, profitable) than CPUs. Quarkcoins are CPU-only mineable as well. My point is: having the CPU at 100% won't add much electric consumption or heat vs. what the GPU is already consuming, but do can add for the final profit. – Joe Pineda Jan 17 '14 at 3:13
  • My fault I didn't know that about Prime until now , thx Joe – Tom Stickel Jan 17 '14 at 6:08

Based on this hardware comparison

1 CPU ~ 50 KH/s

3 rigs x 2 CPU x 50 KH/s each ~ 300 KH/s

At the moment, according to the coinwars, you would mine $9.75 a month or $0.33 a day.

Better mine new alt coin and then convert them into litecoin that will be more convenient. Have a look on coinchoose.com to select a coin with less difficulty and which website is trading them.

  • He'd lose money mining any scrypt-based SHA-256-based coin. CPUs are only good for primecoin, quarkcoin, protoshares and a few others, no more. – Joe Pineda Jan 16 '14 at 21:20
  • Agree with mine new alt coin and convert to litecoin, but not with the OP CPU – Tom Stickel Jan 17 '14 at 1:32

    Khan: the original poster is asking specifically about mining with CPU only for he lacks a GPU and is tight on money to buy one. – Joe Pineda Jan 17 '14 at 19:31
