Oops, I was running bfgminer without the “–scrypt” flag. Like I said, this miner isn’t getting me credit in the pool. At a rate of 1000 Doge = $1.17, I could make $0.62 / day mining Dogecoin at a cost of $0.33 in electricity.If my best rate is 150 khash/sec, that would be about 530 doge/day.The pool tells me a rate of 21 khash/sec is worth 74 doge/day.Turns out I wasn’t setting the –scrypt flag see below. Update: yeah, bfgminer is not getting my credit with the pool and is reporting weird hash/sec speeds. Maybe it’s just not posting work credit correctly. The fact bfgminer is not checking passwords also makes me suspicious. The display literally reads “150 MH/s”, which I was interpreting as a sane kH/s. And the displayed hash/sec values don’t really make sense, or rather the units don’t. bfgminer with just the GPU running never got me any credit in my pool. Nothing seems to check the worker password I set on bfgminer.Those 8 CPUs are only generating 45 kh/s, so it’s better to run GPU only. There’s contention between the GPU and CPU client.The GPU miner costs about 100W to run, or about $0.33 cents a day.It appears to work, yields about 150khash/second.īfgminer -S opencl:auto -o :3002 -u workername -p password I was able to run the MacMiner’s version of bgfminer by hand from the command line.I had about 4 hanging around before I figured out why my Mac was so slow even though I’d shut off all the doges. When the MacMiner GPU client crashes, the whole applications crashes but it manages to leave behind a running bfgminer process that is consuming resources somehow.In MacMiner I tried using these command line flags I found on the 6970M stats page and it still crashes.(it’s an EXC_BAD_ACCESS, KERN_INVALID_ADDRESS, on the main thread). There are some flags to tune the GPU usage settings but I have them all set to defaults. The MacMiner GPU client crashes on my iMac soon after starting to run.I wonder how the pool average is 1400? Surely no one is building Dogecoin mining rigs. According to that list very few GPUs push 1000 khash/second.That’s about 5x what my CPUs can do a significant improvement, but not ridiculously so. According to this litecoin site my AMD 6970M GPU should get about 210khash / second.Temperature isn’t so bad, the fans aren’t making noise. My Mac is using about 140W running the CPU miner, or about $1 / day at PG&Es outrageously high price for electricity.I’m not sure, but I suspect “worker” means “single computer” in the pool, so this is a fair comparison. So my worker is about 3% of the average worker. The pool as a whole is doing 8.2G Hash/sec with 5891 worker, or an average of 1400 khash/second for a worker.I have 8 CPUs, so I’m doing about 45 khash/second. Each CPU (i7 at 3.4GHz) is giving me about 5.7 khash/second. It’s basically a GUI wrapper for command line tools, including bfgminer. cgminer recommends Asteroid, which hung for 1+ minutes with no UI feedback. I tried several miners. fast-pool recommends cgminer, which is an awkward command line program and lacks the –scrypt flag they try.The mining pool I picked is fast-coin.(Or do: is it encrypted adequately in the backup?) Have to exclude both the “blocks” and “chainstate” directories but then don’t exclude wallet.dat from the backup! That’d be dumb. Or use an alternate client that doesn’t require the whole blockchain: maybe MultiBit maybe something from Crashplan will try to back up the Dogecoin state, including gigabytes of blockchain data. Apparently the initial sync can be made faster by download a file separately. That is still very big, gigabytes I think.
