I have a gt 640 on win 7 x64 and I am currently mining on a pool with it. In the interest of sharing information then asking for more. I will put down what I am currently doing so that others can use that and build off it.
Currently I am using cudaminer 2013-12-8 you can download that here
https://www.dropbox.com/s/siu1k70tx6v51gg/cudaminer-2013-12-18.zip I downloaded it from there and unzipped it, opening the x64 folder
I then opened notepad by right clicking-new-notepad and put in exactly this text below
cudaminer -o stratum+tcp://middlecoin.com:3333 -u 12L1CCD7JmgqM4SDei3dvEG4ZhdGYZm17i
I did not leave any spaces before the "c" in cudaminer or after the "i" in the last line of text.
I then chose "save as" and in the drop-box that says "Text document .txt" I changed that to "all files" and named the file RUN.bat I saved that file in the same folder (cudaminer-2013-12-8/x64) and double clicked the file I just made. it opened a command box (dos box) and started running. takes a few seconds to optimize. Keep a browser open, do not let your computer turn off the monitor, hard drive or graphics cards, set a blank screensaver and it should run overnight.
What that does is that my computer mines for alt-coins such as doge, BBQ coin, ANC, and many of the rest. It is in a pool with a fee for changing what is mined automatically and then converting what has been mined to Bitcoin, then after 0.001BTC has been reached, it pays out into my bitcoin address.
The last chunk of code is my bitcoin address if anyone wants to send a
very small tip (pm me and I can verify that it arrived) I am currently mining at around 63KHs
You should be able to use exactly that set-up if you have an nvidia card and an x64 windows 7 computer, just get rid of my bitcoin address and substitute your own. You can check to see if it is working by going to
www.middlecoin.com and ctrl-f and typing in a few digits of your bitcoin address (it should show up after about 20 minutes. If after you do not see anything after 20 minutes, you did something wrong.
NOW.
My question.
How do you start solo-mining? I would need instructions that are similar in detail to that above, and can give a very small tip.
