I just got started today and i have a few questions on running my systems.
i am sitting on a bunch of servers(at data centers) and a bunch of boxes at home. my main has a radeon hd 5770 with an i7 that has 12 threads and currently running under 80c for the GUP is that bad? im getting 180 mhash/s.
Do you mean GPU? GPU's aren't efficient enough to make a profit mining; the cost of electricity is greater than the value of the bitcoins earned. It would be more cost effective and easier to buy some bitcoins.
if i want to add more machines to GUIMiner what do i need to install to all the other machines to tie them all together it all goes to my bitcoin address.
Are you mining solo or on a pool? Either way you will need to install guiminer on every machine you plan to mine with. Then, if your mining in a pool, configure all of them to mine on your pool account. Or, if you are mining solo, point all of them towards your bitcoin client (you only need to run this on one computer).
how are bitcoin addresses assigned? is it by computer? do you have to sign up somewhere to get one? is it the one under recieve coins?
I'm going to assume you are using the "official" bitcoin client (Bitcoin-QT). Bitcoin addresses are not assigned and they are complete independent of the computer. Bitcoin addresses are "generated" by the bitcoin client. You can create as many bitcoin addresses as you want and each address is independent of all the others. Yes you can create more bitcoin addresses under the recieve coins tab, I believe the button is labeled "create new receiving address".
I hope this answers your questions, feel free to post if you any other questions, but most questions should be easily answered by searching the forum.
