That's great

Thank you for that and for your great work!

Hi!

Thank you very much for CoinMap it is a great idea .
But I have a question for you, do you have data about number of new locacion added each day or weak since the beggining?
I am working on my master thesis, where I am going to explain the idea of bitcoin and source of it's value. Probably number of places where you can use it physically is one of the important factor. If you have such data it will be really healpfull for me.

Than you in advance

Thank's for answer. You are rigth MSI is much cooler than Gigabyte .

But there is something strange with all my rigs (they are 2 cards per mobo) - one card is cool, and the other one is overheating.

I can't see any cause of that, both cards has same conditions. Anyone has that problem and know what to do? I heard something about dummy plug, tried this but it doesn't change anything.


Software:
AMD 12.8
SDK 2.7
Cgminer 3.3.0
It seems to be the most stable combination

Hardware:
Asrock Extreme 4 Z77
2 x MSI 7950 TwinFrozr III
4 GB Ram
650 Gold PSU

@fcmatt
I totaly agree what it is slow (I think 20-30 khash/sec is realistic), you should always buy stable components too .
But talking to the point:

1)You buy cheaper components (as I show examples)
2)You aren't forced to mine on APU, you do it only if you want to (I think extra 40 W (?) is worth it, I know it is less efficient that 7950 but it's extra )

So why not buy such a changed rig? Are AMD motherboard chipset or CPU not stable? Or are they really immpossible to configurate well?

Thanks for your answer.

P.S. What about USB instead of HDD, and Gigabyte 7950 instead of MSI Frozen ?

I'm quite new here so first of all I want to say hello

Second thank's for great tutorial Tacotime !

But I'm wondering, is it the most cost effective way to mine litecon?
Why don't change:
1)motherboard to
http://www.newegg.ca/Product/Product.aspx?Item=N82E16813157339&Tpk=fm2a85x%20extreme6&IsVirtualParent=1
(ASRock FM2A85X Extreme6)
2)processor to http://www.newegg.ca/Product/Product.aspx?Item=N82E16819113343
(ATI APU A4-4000)
3)hdd to http://www.newegg.ca/Product/Product.aspx?Item=N82E16820239405
(Kingston DataTraveler 111 32GB USB 3.0)
4)graphic card to
http://www.newegg.ca/Product/Product.aspx?Item=N82E16814125414&Tpk=gigabyte%207950&IsVirtualParent=1
(Gigabyte 7950 - it's cheaper and it has 3 fans instead of 2)

As you can see all those parts are cheaper than suggested by Tacotime.
Futhermore with ati processor we can (theoretically?) mine litecoin on extra graphic
card built-in processor

So I have three questions:
1)What do you thing about those changes in configuration? (I read something that using ATI CPU decrease efficiency of GPU's but I didn't find any approval of that information)
2)Is it hard/possible to configure that stuff (3 x 7950 + APU) + installation on USB (Ubuntu).
3)Will Gigabyte cards be cooler - each has 3 fan's.

Thank's very much for your reply

P.S. A month ago I built something like Tacotime rig to check if I can mine and it's quite OK. But I am going to enhance my mining power and now it must be as cost efficient as it is possible ;] Maybe I should put my mining rig in China, i heard that they have cheap eletric power .

I can't help with wind, but about solar:

Sunny hours are not sufficient, you need to know your Insolation. Some approximation can be made of this graph http://en.wikipedia.org/wiki/File:SolarGIS-Solar-map-Europe-en.png
Total photovoltaic pharm efficiency is about 15%, so if you have the insolation (on m2) multiply it by 0,15 and you have power which can be made by your solar system within 1 year, using 1 m2.
The problem is - mining any crypto need stable energy, so you can't use solar energy (what about nigh?).

So in my opinion producing electric power from "green" energy is a topic for some other forum (which is specifically about that), because it isn't really connected with mining.
You can easily mine without using green energy and produce green energy without mining .

Ok, sorry.
I will search closely next time...

It's my first topic so i want to say hello

I found interesting project - http://lifeonbitcoin.com/ two people will buy only for BTC for 90 days.
I think it's really nice, first of all we'll see if it's possible , second more people will know about cryptocurrency's and the last but not least they should make quite nice list of placec which accepted BTC.

What do you think about it ?

Why ? What's wrong. Theoretically it is only an extra GPU. What system do you use?
