I know a lot of people say you need a decent amount of memory for scrypt mining but I still don't understand why. If I look in taskmgr I see cgminer taking up ~55MB. I am using two 290's. Thoughts?
A lot of people are clueless. I have 5x 290s per mobo with 4GB of ram, and never had an issue. 2GB of ram should be more then enough for a linux miner. That said, the distros like bamt are messed and seem to eat RAM, but my gentoo installs have 90% free memory no matter how many cards are installed. The Asrock BTC boards will run 5 or 6 R9 290s no problem. I am curious on your 5 card rig what are you getting per card? Do you ahve the 290 or the 290x's? What model card? Right now I have 3x 5 card rigs, all with R9 290 (non-X). I get 900KH/s/card consistently (899-901KH always). I also have a 4 card rig with Sapphire R9 290 Tri-x cards, which all get 945KH/s/card consistently except for one card that won't take the memory overclock and runs at 905KH/s. |

Lowering your intensity is unlikely to significantly reduce your stales (most common rejects you will get on say middlecoin) on wafflepool, because wafflepool still accepts shares that are 1 block behind (just not 2 blocks behind). Stop assuming stuff guys...
Also, stop using the old intensity system... xintensity will give you much more granularity and probably increase your hashrate a bit too.

You dont need plugs any more. Multiple MBs all with dif configs, and they mine just fine without the plugs.
Agreed. Dummy plugs are unnecessary. |

Have you got 5x 290 Tri-x setup yet?
Interested to see if they are stable, as the R9 290's are hit and miss with more than 3.
bump I have 4 running stable paired with 4GB of ram and the cheapest LGA1150 CPU. Pulling a consistent 945KH/s+ on 3 cards, and over 900KH/s on 1 card (which won't take the memory overclock... yet), straight out of the box with no burn-in. I see no reason I couldn't add a fifth (other then that I can get other 290 cards for cheaper, so I won't bother)  (Rejects are almost entirely because of vardiff causing Share below target) |

what are your settings phzi? i cant pull much more than 912 on both of mine.
Right now I have stabilized to: "gpu-threads" : "1",
"xintensity" : "1100",
"thread-concurrency" : "25601",
"worksize" : "512",
"lookup-gap" : "2",
"gpu-fan" : "80",
"gpu-powertune" : "20",
"gpu-memclock" : "1499,1499,1499,1250",
"gpu-engine" : "1060,1060,1060,1020" This yields consistently over 945KH/s (945-948) and over 900KH/s (901-905). Reject rates are down around 0.3% (almost all my rejects are because of vardiff causing Share above target), and WU is consistent with hashrate. The 1250/1020 card faults after about an hour if I push it beyond 1040, so I pulled it back to 1020 as seems to be stable so far.

My cards are running 875 with a power consumption of 315 watts.
Ratio 2.77.
Cany anyone beat this? Power consumption really doesn't matter at current mining profitability, unless you are paying a lot for power. Tuning power consumption might be relevant later to extend the life of equipment, but right now you should be optimizing output not power consumption. My rigs pay off their monthly power consumption in 1-2 days of mining, bringing that down slightly and losing a big chunk of income makes no sense. I have 3x R9 290 Tri-X OC running at over 945KH/s, and 1x running at 930KH/s. (The 930KH/s won't take the memory overclock, so it runs at 1250). Max temp is 75 degrees at 80% fan. -- Regarding RAM... WTF are you guys talking about? I have my 4 cards running with 4GB of whatever-was-cheapest DDR3 RAM. If you need more RAM for mining, you're doing something wrong. |

I am loving my Tri-X OCs so far. Easiest R9 290s I have tuned by far.
Straight out of the box, with no burn in, I have 4x Sapphire R9 290 Tri-X OC running at 945KH/s, 945KH/s, 945KH/s, and 927KH/s.
The 927KH/s card crashes at 1499 memclock, so I bumped it down to 1250. Hopefully the 4th card will take the memory overclock after some burn in.

around 800
You need to learn how to tune... I have 4x Sapphire R9 290 (NON-X) Tri-X OC cards running at 945KH/s and 900KH/s (for a card that won't take the memory OC). Rig Specs: Gigabyte Z87X-UD3H 4GB DDR3 RAM (cheap stuff) Cheapest LGA1155 CPU Available 4x Sapphire R9 290 Tri-X OC SGMiner Config: "gpu-threads" : "1",
"xintensity" : "1100",
"thread-concurrency" : "25601",
"worksize" : "512",
"lookup-gap" : "2",
"gpu-powertune" : "20",
"gpu-memclock" : "1499,1499,1499,1250",
"gpu-engine" : "1040,1040,1040,1020"
"gpu-fan" : "80"
Key points: if your card won't overclock to 1499,1500, then downclock it to 1250 to see some performance gain. Every tri-x OC card should be able to do 900KH/s+ straight out of the box, with no burn in. |

if theyre testing a bunch of chips it would make sense that they might be changing the clockspeeds/monitoring cooling and looking at all sorts of metrics, as well as possibly testing drivers and programs because the other asics came online with cgminer supporting them... that wont be the case for scrypt asic
It's bloody ASICs in china guys... Do your research. |
|
|

If you go to the link and read the specs, you see it says Gridseed GC3355 X 5. Which means each USB device contains 5 chips. Each chip does around ~60 KH/s. So one of the USB devices will do ~300KH/s. They are selling them in batches of 10. So for the $1360 you get 10 of them. Basically totalling ~3.0 MH/s
Here's what is says in chinese:
品牌：Gridseed 格瑞思捷
芯片：Gridseed GC3355 X 5
You can see it says there are 5 chips in the device.
An actual chinese person that translated this stuff properly says it's basically $500 for ONE USB miner hashing at 360KH/s... so no, you're totally wrong and showing your stupidity again buddy. They were only sold in batches of 10 USB miners, to only 40 people. 360KH x 400 = 144MH/s total... hardly a big deal. The only benefit of scrypt asic so far is the power consumption - but that's not going to really matter to GPU miners for at least a few months. |

To all those worried about the payouts... Once I add up my additional unexchanged along with what I'll already be paid, it looks like the value per MH/s will be just under 0.01BTC
Today's value of your unexchanged doesn't mean much though, the conversion rate at the moment of exchange can be significantly different and result in less (or more) btc. For example a couple of days ago, a big piece of blue was converted to red for only +-70% of its stated value. Meh, just as often it ends up being worth more. It tends to average out over time. |

Hi!
The real question here is why H20 donīt reply on this topic, and OFC refute all the acusations being made here...
I still donīt get it...
It so hard to speak here? Put all our mind to ease?
I donīt think his a scammer (i donīt have the knoledge to know just looking the graphs), but all this silence we wonder... why?
And donīt say he donīt have the time...
Come on...
Best Regards,
LPC
Simple - H20 has better things to do. There isn't a single "accusation" in this thread worth a penny let along worth responding to. |

Tealover is a prime example of someone who jumped off a ship, swam to another ship, and is butthurt that he isn't making the same profits. If Tealover was actually mining on another pool and making great profits, you can be sure he wouldn't be trolling in this thread like a maniac. I would suggest that he's a shill for another up-coming auto-switching auto-trading pool, but I am pretty sure he doesn't have enough brains for that.
SimonG: LOLOLOLOLOL. You are very funny.
Tealover: seriously, newb... nobody cares if you have his contact information. Congratulations? What did you PM him anyway? A ransom demand, huh? Why are you so butt hurt?
I'm pretty sure you have him pegged lol trying to blackmail. I've been paid my dues from this pool several times and don't really care who h20 is as long as I get paid. If I don't get paid its simple just stop mining at the pool. I'm not saying he's going to take 1 big scam run and stop paying. I'm saying he is definitely taking more than the 3.4% fee he says. More like 8-10% fee. Small enough for you to not really notice, but big enough for him to go from $4,000/day profit to $10,000/day profit. 1. You have no proof, so STFU 2. What are you expecting him to say to you? You said if he didn't meet your demand within a day, you'd release his info... so: 3. Are you trying to blackmail him? |

And stats are back... looks like that incline outpaces the prior part of the day too. Woot Woot.

And PS, if I was the pool owner, and got 3,xxx% pool fee, I would have bought a decent monitoring tool, that wakes me up in the middle of the night if something is terribly wrong.
Stats not showing up for half a day isn't something I would consider "terribly wrong". Annoying, maybe. But if doesn't affect payouts, who cares? tealover: just shut up already you wanker... |

Seriously concerned about the flatlined statistics for the last several hours! How are we to account for whether some percentage did not magically disappear during the earnings from this time period? Absolutely need more feedback and transparency with the way things are going on?
Chill out... You want transparency, go somewhere else. You want to get paid every night in BTC, mine here. Worst case you're going to lose 1 day of mining revenue. Almost certainly the front end lost connectivity with the backend, and stats are simply not being updated. Give it a bit everyone, it is the weekend afterall. (Or please leave, I wouldn't complain about middlecoin becoming a bit smaller again). Are you 5 years old or f'ing insane? Is this the inner workings of the mafia or a top secret research facility we are talking about that we can't question? If the operator is charging a fee for this service, I have the right to ask for things to be improved. H20 himself has not posted to tell people to go somewhere else if they do not like it, where you do get off taking on that responsibility kissing his a$$? I understand how much custom code and work is involved in middlecoin, and I am mature enough (unlike you it seems) to not freak out if H2O is sleeping in today and hasn't fixed a display bug... If I don't get a payout one night, I will move to another pool. Until then, middlecoin is the most profitable/easiest place to mine. This pool is designed around a LACK of transparency. It says so all over the FAQ. So, I say again, don't like it, mine somewhere else. And please feel free to suggest another pool with middlecoin's features and track record... Besides, all you people complaining about mining Doge and LTC... When you actually consider market depth and stability a little bit, they are likely the most profitable coins to be mining. But please, go mine Norbits or whatever is at the top of CoinWarz (which doesn't consider market depth, so is nearly useless), and let us know how that compares to middlecoin. |

Amazing that people stays here.
Show us a pool that compares... Oh wait, you are keeping your newly discovered pool a 'secret'... <heavy sarcasm> right... </sarcasm> |
