Your electricity bill would change, since browsing the internet does not put your card at full load. Just to give you an idea, my 660Ti rig drew 140ish watts when idling (i.e. browsing internet, very light usage) and up to 320ish if i remember correctly when mining. At least where I live, that's almost 2 cents more per hourWith the 660Ti, I was able to get about 55kh/s, so you could probably pull a little more from the 670. I'd say if you have free energy, you might as well, but otherwise the earnings after energy cost would probably not be worth it.Do what I did: sell your nvidia and buy a radeon (i went from 660ti (55kh) to 7950 (500kh, could go higher but i'm hitting temperature issues))
Let's see....if you had mined with that card for the past year...and in the last month the price jumped from 0.06 to 5.80 how much money would you have made? Lots. Go ahead and mine; although once your hooked you might find yourself buying a card designed for mining.Was the pool you were trying to mine on using Stratum? I'm not sure if that works with reaper (reaper users if I'm wrong please tell op) without a proxy. Try to connecting to Burnsides or NuKings which use's different protocol.
I was trying to solo mine, I just right now read this guide: https://bitcointalk.org/index.php?topic=83371.0and I retraced my steps and this time reaper no longer crashes, however I get this error: http://i.imgur.com/M4yHAv5.png
You can just join it. www.coinotron.com is my preferred pool so far.Don't bother solo mining with an nvidia, it is pretty unlikely for you to find a block anytime soon.I haven't used reaper, but cgminer was not difficult to set up. From what I've heard, reaper seems a little unstable. If you feel like switching to cgminer, i can help you with that.
Go to http://ck.kolivas.org/apps/cgminer/ and download the "cgminer-2.11.3-win32.zip" and extract it.Open notepad++ or notepad, whichever you prefer, and just have this one line in it (this is assuming you will use coinotron, but you can adjust for whatever pool you choose):cgminer.exe -o stratum+tcp://coinotron.com:3334 -u UserName.1 -p x --shaders 1344 --intensity 11 --worksize 256 --scryptSave this file as ***.bat (whatever you feel like calling it, I call mine ltc.bat) inside the folder that cgminer.exe is in.This is what worked best for me on the 660Ti. Increasing the intensity further just caused desktop lag with no noticeable increase in hashrate.Now double click the .bat or run it from a command prompt and you should be mining. let me know if you have any issues!
Well I'm able to overclock both GPU and memory with the lower voltage. I lowered watts by 60 to 70 per card. And reduced temperature significantly which increases the life cycle of my video card. If that doesn't sound appealing suit yourselves.Here's my stability after 36 hours run time. At 1.049V and memory at 1.524 down from 1.125 and 1.550 on my 7950.Keep in mind this is also the result of my first attempt at configuring the new version of cgminer. Based on my experiments so far I believe I've maxed out or am close to it for GPU 1 (maybe a slight increase in voltage will allow a faster hash rate there). With GPU 0 and 2 I think I can get another 30 to 60 kh/s. Next weekend when I have some time I'll try pushing them a little further.I'm very thankful for all the individuals who have made it possible for me to make money out of nothing more than a hobby. The providers of all this open source software have generously made this possible. I support them by donations. Even more so I support them by trying my best to provide accurate and honest information to others. In the spirit of the open source concept.
