Just to clarify, the multiple pool arguments are accepted but the miner doesn't actually failover. I don't think readme / help is updated with the failover yet, wasn't when I looked, but will double check tonight.

Thanks guys. I will have a root around in the previous pages. I follow the thread and don't recall seeing it. I was using the usual -o pool1details -o pool2details, which I had read elsewhere was correct for Cudaminer
As for guides, that's pretty key - a lot of stuff gets lost or is asked many times in this monster thread. There are quite a few up now at Cudaminers.net but because of Christian posting here (esp. release details) and the collective wisdom in this thread, they don't have much traction. If Christian moves over there then I expect we can organise things like those key guides in to stickies.

Anyone succesfully using the failover on Cudaminer master from Git? I tried using it to run on NiceHash with Clevermining backup (to take advantage of this Whitecoin business) but it wouldn't switch over. I then ran a few tests with e.g. a wrong stratum address etc. and I still didn't seem to switch between pools.

Everyone running Windows? :/
Win7 x64 with 6x 750 ti Seems like windows is preferred, and certainly a lot easier to handle (particularly if you are a complete Linux novice like me...). I will report back on any attempts at Linux overclocking, for anyone that does happen to use it! Very easy to start and handle with Linux is to use KopiemTu "out-of-box" Linux solution, verified 6xGPU: https://litecointalk.org/index.php?topic=16800.msg159161#msg159161 btw, there is such question in this thread: "With screen -r invoking the cudaminer display (all those yay!! rolling by...) is there a list of commands to use on that display? The only one I am aware of is Ctrl-C to quit. More helpful would be something to, say, show the gpu settings. Or, something to adjust the mining operation."Thank you JK. I had seen Kopie and it looks great. The reason I use Linux is because my cards are in my media server/backup box so I couldn't switch. |

On the latest nvidia driver for linux 337.12. with cuda 6 Unfortunately i cant tell what options are in the nvidia-settings as my monitor is plugged into the intel video. From the cli tho everything looks fine. ccminer works well, i think there is a slight increase, but could be placebo. +------------------------------------------------------+

Great. Will give the drivers and overclocking a go when I get a chance. Benchmarks for gaming elsewhere suggest it may not be working properly. How are you overclocking in the BIOS, I thought you could only set power target in there which is not worth it? |

Just wondering, has anyone tried the latest beta linux drivers that enable overclocking? I'm using my 750Tis in my media/backup server, so it's running linux. Would be good to boost the hashrate a little!
Also, any documentation yet for the latest commits on Git? I was wondering how the failover works i.e. does it return to the original pool when it comes back up? I'm not using it yet as an mining YAC and I believe the latest don't do jane yet?

something I don't understand... bitcoin is going down and the altcoins are also going down... If there was some logic, they should go up (as the logic is to assume that nobody will sell their hard mined coin for nothing...) It's because trading pairs for most alts are to Bitcoin. There aren't many altcoins which have trading pairs to any fiat currencies. If the price of BTC in USD goes down, the price of altcoins in USD goes down. However, this doesn't necessarily mean that the Altcoin price in BTC has gone down, so provided the alt to BTC price hasn't changed, you'll still get the same amount of BTC for your altcoins. Coinmarketcap is just doing an extra conversion of alt->btc->usd, which is why the USD price is actually dropping. If you sort coinmarketcap by Change (24h) then usually you can see a handful of coins going up even though BTC is going down, which means that not only has the alt-btc price gone up by however much percentage, it has gone up by even more than that due to btc also going down. The issue is that many usual-suspect mining coins are also going down vs BTC. Essentially losing value twice. They are not holding at the same coin/BTC rate. |

I have to say Christian, your efforts here + those of the other Christian are pretty heroic! I've not yet tried HVC, but my sense is that it's less profitable than scrypt jane coins even though it has lower power consumption. Am I incorrect, or is everyone going long on HVC? Does anyone have a good site to compare the various coins in a single place, and account for power etc.? At the moment things like HVC aren't on the usual Coinwarz etc. so need to visit many sites. http://cryptoage.com/ does seem to be a decent comparison, but lacks the power piece. Though I suppose I am being slightly lazy, as that is pretty easy to calculate and subtract.... As an aside, have you shelved plans to add failover support to Cudaminer or ccminer Christian? This would be really handy! If people are interested I have a Linux script I use that I think covers it (kindly written by a friend), switching to a failover pool and then rechecking the main pool after a defined period of time. |

Thank you, got me 15% more hash rate! Donations accepted: UTC: UWDDqaFU4pqiCeDs4Ypkxs5mTQcZ1E82if  Only just started mining, but will drop you something when I get a payout Sending a few coins your way for the trouble, not much but still wanted to say thanks! |

Ok ty guys , im now on http://utc.greekpool.eu/ , with 150 khs ( my 2 Nvidia gtx 750ti ) im make 27 UTC day , its good or bad ? . Sounds nice! How are you getting such a high hashrate from the 750tis? I'm pulling about 50kh. What settings are you using? -l T5x24 -m 1 -H 2 -L 2 here. |

Thank you to bumface and TheStuhlman for working to address the challenges with hash distribution

Quite new to the coin, but sad to see this situation with Nitro. Mining on Leet and we're getting 30%+ orphans. Makes for depressing mining. Is something going to be done? Not really viable long term if one pool has all the hash, killing things  |

If anyone has or is mining Ultra Coin with a 750ti, does 55 kh/s sound about right?
I would be interested to know. What settings are you using? I tried very briefly this weekend and only got 35! cudaminer -a scrypt-jane:UltraCoin -d 2 -l T5x24 -i 0 -m 1 -L 2 -H 2 Have the Core overclocked to 1186 and memory at 1513. Also on newest driver 335.23 Thanks! Now just trying to get my 670 to work, but that's terrible... cudaminer.exe -a scrypt-jane:UltraCoin -d 0 -C 1 -i 1 -H 2 -l K5x14 -L 1 This is what I use for my 670 for UltrCoin. If I remember correct the 750ti beats my 670. But I do not overclock my 670 as it is on my main rig with the 750ti's. I have all 3 of my monitors plugged into the 670 so I don't try and bog my rig down by overclocking. Thank you. Seems like it's not worth it for the power usage compared to the ti. Especially as so many orphan blocks with ultra due to nitro |

Is it possible to set up two pools in one config with CUDAMiner? I'm looking to rent out my rig at Betarigs, and to do that I'd need to use two pool addresses and logins in my config.
Unfortunately there is no failover pool function for CUDAMiner yet. Would be very interested in this too. I am keen to give Betarigs a go wondering if it's possible to write a script that will switch off the backup miner when the machine is rented, and switch it back on once Betarig rental is done. |
