hi guys. i've known of BitCoins for a while, but i've just started to really learn about them this past week. nobody i know knows anything about them, so i'm trying to just teach myself from the internet. i started by reading a ton of start off guides and whatnot. i have the bitcoin-qt wallet to start off with. next, since pool mining is my main interest, i followed this guide after the wallet, i downloaded rpcminer for my mac. next, i set up an account on slush's pool and finished the instructions. i think i did everything right, but when i run rpcminer i get
"Starting RPCminer (CPU)...
Client will start 4 miner threads Work will be refreshed every 4000 ms Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 Could not retrieve work from RPC server. CURL return value = 7 No blocks are being hashed right now. This can happen if the application is still starting up, you supplied incorrect parameters, or there is a communications error connecting to the RPC server. Could not retrieve work from RPC server." any help would be greatly appreciated! how can i fix this error? or are the different mining softwares or mining pools that work better? i've tried really hard to get this working myself but i seem to be stuck. i'd really appreciate any hands-on help i can get from people who know their stuff. i have a macboook air with a 1.8GHz intel core i5 ivy bridge processor, and the integrated intel HD Graphics 4000 512 MB. if you need any more information i didn't include to help me, please say so i can fill you in. thanks a ton for looking! Edit- thanks everybody for all the help! Its greatly appreciated. I never thought about overheating it. I'll just consider other options if i do decide to get somewhat serious into mining, like an asic jalepeno or something edit 2- i've found a computer i can use, with an amd fx-8350 inside of it. i'm trying to figure out how many bitcoins i can mine if i start using it soon. i've googled around a lot, but i can't seem to find the hash rate for this GPU. i'm probably going to start mining on it this weekend, but having some sort of a clue of what i can mine would be nice. i'm not looking for a get rich quick sort of thing, i'm just looking to get into mining as more of a hobby. i'd rather not buy a dedicated miner, and i think i can mine a fair amount of bitcoins with the 8350 before all the new ASICs arrive. thanks if anybody knows the hash rate on the 8350!
New miner here. Need some help with RPCMiner and CUDA.
So here goes... I went and set up a new PC because I happened to win a GTX Titan in a lucky draw back in February. There were some issues with the motherboard that I bought and the rig was out of action for about a month. Now that everything is up and running I decided to do a spot of bitcoin mining to test out the system and to make sure everything runs fine. I downloaded GUIMiner and fiddled around with it a bit, then I downloaded RPCMiner as well as Ufasoft. Ufasoft's CPU and GPU mining programs work fine but they don't do CUDA. Thus, I tried to get the CUDA RPCMiner to work but I ran into some problems: C:\guiminer\miners\RPCMiner>rpcminer-cuda.exe -url=http://api2.bitcoin.cz:8332 -user=herp -password=derp -threads=1 -aggression=12 -gpu=0 Client will start 1 miner threads Work will be refreshed every 4000 ms 1 CUDA GPU devices found Setting CUDA device to device 0 Loading module bitcoinminercuda_11.cubin Unable to load CUDA module I've tried googling, it seems that people have this problem but nobody has posted any solutions. Can anyone here help? Much thanks in advance.
I know this is an old question but recently I got a similar server. I've tested rpcminer, GUI Miner (Which is actually UFASoft miner).. Personally the best I've found is CPUMiner.With a hash rate of about 75MH/s, it takes a bit of setting up as CPUMiner is normally used for Litecoin mining. CPUMiner gave me about 10%-20% more than the closest rival, which was rpcminer. How to mine Bitcoins using your CPU (processor) on Windows (This works on all versions of windows, XP, Vista, 7, 8) using rpcminer. You can also use guiminer or bitmoose or a few other programs, but I have found the CPU mining on those to be unusually difficult sometimes, rpcminer is the only one that consistently works. Bitcoind – a daemon program that implements the Bitcoin protocol, is controlled through the command line. It is one of the main components of the Bitcoin network node software. Bitcoin software exists in two forms: a GUI application and a background application (daemon on Unix, service on Windows). Download RPCMiner 2013 for free. Bitcoin miner for nVidia GPUs. This is application for Bitcoin (BTC) mining with CUDA-capable videocards. This project is actually a mod of puddinpop's original RPCMiner. Download cpuminer for free. A CPU miner for Litecoin, Bitcoin, and other cryptocurrencies. cpuminer is a multi-threaded, highly optimized CPU miner for Litecoin, Bitcoin, and other cryptocurrencies. Currently supported algorithms are SHA-256d and scrypt(N, 1, 1).
