What mining software to put on 3 old laptops

[kelvinhall05]

I have 3 old laptops, 2 of them with Celerons and 4gb of RAM, the 3rd with some AMD A6 CPU. What mining software would be most profitable to run on these machines? Thanks!

Pretty sure none will work well

You'll be wasting more electricity for nothing... so, F@H would be best choice.

Bro trust me on this. I had a first gen i5 laptop and I got the crypto bug. Tried bitcoin, litecoin, dogecoin, etc. Ran it for weeks and only ended up wearing out my laptop. To be fair the first gen i series were notorious for running hotter than they should but the point remains. I got basically nil results. Don't waste your time and electricity.

It doesn't really matter what kind of laptop you have - none will produce a profit when you're paying for the electricity (or they will, but the laptop will get so hot it'll wear out in a few months). Especially not CPU mining.

CPU mining is WORTHLESS, it costs more in electricity for the day then you would earn in like a year of CPU mining, you need a dedicated GPU to do any mining, for example an 860m laptop GPU is like a 1,000 times higher hash rate then an i7 4700HQ and will make like 50-60 cents a day (if you mine the right currencies) at best after electricity costs are factored in.

not worth it

Mining on a laptop is useless, not only because they have no significant power, but you would just overheat them and fry them.

another frame of reference, the 4700HQ CPU mines XMR (Monero) at the rate of about 30-35 cents a day, the laptop draws like 50ish watts so like half the profit is going to electrical costs earning you like 15-20 cents a day, just not worth.

 

heck this whole laptop (ROG G750JM-DS71) running a 4700HQ CPU and an 860m earns maybe a dollar a day mining but costs like 20ish cents a day in electricity.

 

here is a good website, once you learn how much hashing power you have for a given currency you can select that currency, plug in your hashrate, power usage of the laptop and cost per kilowatt for your electricity and it will tell you how much you would earn or lose per day/week/month/year

One thing you can check out is HDD mining though if the laptops have reasonable sized drives. You will still only make a dollar or 2 a month though. https://www.burst-team.us/

so it scales based on hard drive capacity? I have a bunch of old hard drives I could use. do you have control over what drives it uses, like I wouldn't want it writing to my SSD a bunch.

It's not writing. It writes once and then reads from the precomputed hashes depending on the job it's confirming. It's basically like rainbow tables for cryptographic hashes.
