How to mine CPU coins for free

[MrGaSp]

You guys do understand that you only get so much processor time/power per month under that free account. After the limit is passed, you will start getting billed.

LOL that was not mentioned in OP...

I've started to use my VPS for mining after reading this thread, its getting 1KH/s on one core, i have 4 available.  I am limited by the machines unused cpu power down to a guaranteed share.  I think it'll get faster at night.  

[Remember remember the 5th of November]

Has anyone done the math to see if mining Litecoin would be profitable on an Amazon EC2 High-CPU Extra Large (8 cores)?  On-demand pricing is $0.68/hr and and spot pricing is $0.216/hr.

I've tried it. It says it has 8 cores, it had only 3...no really, just 3 cores. The Cluster Compute Quadruple Extra Large however has 8 real physical cores, not limited, however it's priced at 1.60 per hour.

Calculations for the free EC2, assuming a generous speed of 1.5 khash/s:

Using http://allchains.info/calc.html tells me that you get 3.961 coins per day, or if you use 750 hours, 750*3.961/24 = 123.78125 LTC
At the current exchange rate (~0.01 BTC/LTC) that gives 1.237 BTC, or (3.25 USD/BTC) about 4 dollars. In total.

Obviously, if you get the more expensive EC2, even with 8 cores, it's not worth the money, as you get about 4/750 = 0.0053 dollar per core per hour. The LTC/difficulty ratio would need to increase ~5 times for this to be beneficial, assuming you actually get 8 cores at $0.216/hr.

You'd have to get 56 Coins an hour to pay for it... or about 0.5MH/s.. oO

Damn damn double damn.  Time to build a server at home with hexacores in it or something.

We need a wiki page for CPU hash rates on scrypt

100% agree with this. Maybe on Litecoin wiki if that exists etc. !?

Theres this: https://github.com/coblee/litecoin/wiki but thats nothing much

Just made the page: https://github.com/coblee/litecoin/wiki/Mining-hardware-comparison
I think you need a github account to edit? I'm not sure. Try and see.

has anyone tried this?

how much did you get out?
and how much is the equivalent in BTC?

cheers

I indeed launched a so called "free" micro instance, and it seems to be to be billed in my account activity report... until I see the real bill at the end of the month, I'm not running this again. Luckily I had some issue with putty and the key so didn't actually run the instance for more than an hour.

you do need a github account yep
Here is my cpu info for someone to add
1055t @ 3.7ghz/2.6ghz nb. 3.88 kh/s per core (23.3kh/s per cpu), tenebrix miner/cpuminer, k10 flags on gcc4.1.6. Os is ubuntu, power usage is 225w.

What do you need a Github acct for?

I've been mining on the micro instance for a couple days now.  I'm not getting much out of it.  The speed fluctuates wildly.
