Thanks for the info. I get similar reject rates that you report on waffle.
It's interesting to see all the new multi-scrypt coin pool popping up. So far I can't see any clear reason to choose one over another. The margins are all pretty close and fluctuate by what appears to be luck mixed in with some trading luck/timing as well. Although it does seem like MC has more bad days lately. I think that pool's strategy relied more on luck which is better with more hash power.. just my educated guess though.
edit: I was on MC for about a month and more recently have been trying Waffle while watching new pools with great interest.
I personally am at CM and have been for about 2 weeks (since MC sunk in profitability), minus a few days testing other pools. It has the highest profitability average so far, has informative website and the owner communicates really well with the community (unlike h2o). Obviously, the most important part (for me anyway) is the profitability. SG is really close, if they can increase profitability and / or reduce the reject than it might be worth a shot. Although gotta keep in mind that the fee here is quite high, 2% base + 1.3% for exchanging (from my understanding, correct me if I'm wrong). 3.3% fee is the 2nd highest among switching pools and for the end user has the same affect as rejects. |

So what's the average btc to mh/s here?
Well, I tried it yesterday for 8 hours, waited a day (for unexchanged, immature and such - although I might need to wait longer, not sure) and I got 0.0062 with 2.6 MH/s, which equates to 0.00715 BTC / MHs / Day. Since earnings per day fluctuates, what I did was to compare ScryptGuilds performance to the other pools performance in the same day. In that case ScryptGuild did better than Waffle, MC and possibly Hashcows (can't say for sure here) but was under CM. I did include in my calculation the reject rate I got here and what I usually get on other pools (in CM and SG I get 5%~ reject with -i 18, 3%~ on hashcows and MC and 0-0.3% on Waffle). |

I'm sorry to say the experiment has already gone awry. All four rigs have been hashing stable for weeks, but unfortunately two of the rigs became unstable right after I switched the pool management. The dedicated Middlecoin rig and the load balancing rig are both hashing fine, but the Clevermining and Wafflepool rigs each had one video card go dead. I think it may be a heat issue since this is the hottest day I have seen with this setup to date and the middle two rigs are the ones that had a card go down. The two rigs hashing away fine are on the "outside" of the lineup like bookends.
What is strange is cgminer is unresponsive/not updating, but according to the pools, both rigs are still sending shares minus the two dead cards. Instead of listing the cards as dead cgminer shows the fan speed as zero and the temp as 511 degrees. I'm guessing they hit some kind of thermal cut off. I'm going to restart them now that it's cooler and see what happens, but it threw a wrench in the numbers right from the start. : (

If you wanna make a proper test, you should also (in addition of what Kalroth said) make 3 new BTC addresses and aim each rig to a separated address, that way you avoid dust adding to your balance and affecting your results (I know you said you removed first day of payment from MC to do so, but that's not enough. I got dust payment from MC a week after I stopped mining there and it was pretty big payment too). |

and yes i have those at the top of my BAT... this is why i am so confused - everything appears to be ok, just shed loads of HW errors.... maybe i will stick to 280x for the next rig... these i can build and have running within an hour  Try increasing your TC value before you go to sleep. With 6GB you should be able to run higher TC than what I wrote. When i tried to use what appears to be the standard 290 TC CGminer would not boot - buffer problems.... think it was 32765 or something in this order I had since put another 2gb in so running 8gb now.... worked fine using the TC in your setup - but will try boosting it in the morning now... Time to be nice to the mrs and daughter and explain what i have been doing all day is worth while and super productive... Its hard enough to explain why i spend so much money on the "ROOM HEATERS" ^^ My system has only 4GB though... RAM isn't your issue. |

Could be -xI , not sure if it's case sensitive or not. Anyway, I'm not sure it's -xI at all , since I'm using a cfg file to run my miner (easier for me to see all the settings) and there aren't any short keys there.
What memory type do you have? You might need to change to clock speeds since mine are based off HynixAFR.
Also, you might wanna try and delete your bin files.
Edit: Forgot to mention that most HW errors are caused due to to low TC value, do you have "setx GPU_MAX_ALLOC_PERCENT 100" "setx GPU_USE_SYNC_OBJECTS 1" ?

thanks for this buddy - just changed up to 8gb ram to see if that helps - and sods law both the pools i use are down for work... so i will wait half an hour before i try this.
quick question though how do i input the xintensity... i use BAT files so ordinarily i would simply do -I 20 ... and for Xintensity???
-xi 400 |

I am running 3x R9 290 and using SGminer 4.1.0
"xintensity" : "111,111,111",
"worksize" : "256,256,256",
"kernel" : "zuikkis,zuikkis,zuikkis",
"lookup-gap" : "2,2,2",
"thread-concurrency" : "20481,20481,20481",
"gpu-memclock" : "1250,1250,1250",
"gpu-engine" : "1015,1015,1015",
"gpu-threads" : "1,1,1",
"expiry" : "10",
"scan-time" : "5",
"queue" : "0",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"log" : "5",
"no-pool-disable" : true,
"temp-overheat" : "85,85,85",
"temp-cutoff" : "90,90,90",
"gpu-powertune" : "20,20,20",
"kernel-path" : "/usr/local/bin"
xintensity 111 equates to -i 18~ so depending on the pool you're mining at, feel free to change it, for example: xint 400 equates to -i 20~.
Also, depending on which memory type you have you might need to change your clocks speeds to get optimal speeds.

I've switched to http://www.coinmine.pw for the time being until things pick back up for clevermining and the other pools. I like that coinmine.pw actualy supports vardiff too  Something clevermining use to support once a upon a time. Do they have the auto-payout in BTC feature? Or is it just another multipool?  No autosell, you have to trade the coins manually/yourself. It's easy to claim high profitability if you don't exchange to BTC and don't deliver BTC. Guess what. There's a coin which can give 180% LTC theoretical profitability. The only problem is that it's only on some very niche exchanges and its trading volume is 1 BTC/day and orders depth is for 0.1 BTC. The 180% LTC is purely theoretical. You can have it for 0.1 BTC worth of coins and then you need to go back to less profitable coins for the other 99.9 BTC. CleverMining is about real profits, not theoretical speculation. I'm not going to leave you with bunch of niche coins which you won't know what to do with. Mining coins is only part of the equation. You need to actually sell them to get your profits. It's worthless to make profitability stats based on coins which you won't be able to sell. The altcoins market is really bad these days but I'm working very hard to deliver the best profitability among coin-switching pools. What I've been working on for the whole night I think is working well, as we're back to 127% LTC profitability from 100% yesterday, while other pools are still down (Waffle stats page show today 0.0059 which is 90% LTC). But you have the option to hold on to the coins you mined to next week or so, by then the price is up and the revenue for this days mining is higher then exchanging right away. Just set selling price 20 percent higher as current prices, and your mining returns are 20 percent higher It this... is this kid for real? I mean, you for real?  |

Post your config here.
But regardless, since you used to handle 280x I'd venture to guess you're using -g 2 ? If that's the case than R9 290 are using -g 1 and with that you can also increase the TC (20481, 24500, 32765 works for most pretty well).
Hi, thanks for the reply. I have actually stripped back the entire config to realise it was the intensity causing the issues... but i had already changed the -g 1 after spending the last few hours on google trying to fix this before posting here... my config is purely stock right now - its simply when i change the intensity it goes crazy - stock intensity is 8 - even trying the 280x "normal" of 13 causes issues so you can imagine what happens when i go -I 20  Intensity isn't the cause but rather the symptom, so it has to be something else. Try SGminer (4 or 4.1) and see if it's working well there. I remember when I got my first R9 290 I couldn't get it to hash properly using cgminer (wouldn be stuck at 500~) and when I switched to sgminer (with exact same settings) everything worked just fine. |

my friend has a sapphire r9 290 in but its only getting 558kh
no errors, but isnt this card supposed to do 750-800kh??
here are the settings
using the newest multiminer
--scrypt -I 13 -g 2 -w 256 --thread-concurrency 8192 --auto-fan --auto-gpu --gpu-engine 1070 --gpu-memclock 1400
what is doing wrong? if i try to push the I to 14 i get 100% errors
help me obi wai, your my only hope
R9 290 uses 1 gpu thread, so: -g1 and --thread-concurrency 20481 (although this value will vary depending on how much RAM you system has), after you change both of these you should be able to increase -i and not see any hw errors. After that, play around with your core clock and mem clock speeds. |

Teamviewer - It just lets you remotely control the entire PC, so I use it in conjunction with CGwatcher.
TeamViewer reduces the hashrate. It doesn't. At least, didn't for me. |

Mining there since March 1st with 3.6 Mh and one payout of .03. Nothing else even showing in my account, and payouts have tanked. At this point I don't expect to ever see those missing coins. Whether this is actually a scam pool or not, its lack of transparency has the same effect as if it were one.
You will see those coins, just give it some more time, keep checking your account once a day and you'll see. Just go read previous posts and you'll see lots of other miners stating the same (me included) and a few days later report that they received their coins, in full. I do agree that the pool lack of stats is a major issue, but from there to hashcows being a scam is an overstep. |

It can take days after a round is ended for the coin to mature and be traded. So you have to be patient. I suspect that it won't always be like this but for now it is what it is.
so why is hashcows so slow to do it ? when others arent even coinsolver a smaller pool converts the coins the same day. It's the coin, not hashcows. I was thinking the same about a week ago when I tried hashcows out, and a few days after I started getting payments for the days before when I mined. So don't worry, you'll get what you mined. |

I presume that the overall power usage would be 30-40 watts x 3, which is 90-120 watts.
Would that really be too much for the motherboard to handle?
Thanks
If that's the case, than no, it wouldn't be to much for the motherboard to handle and you can safely skip powered risers. I was thinking you'd wanna buy a lot more cards thus said with quite certainty that you'd need powered risers. |
