Hello, I'm crossposting here from the sph sgminer thread, I know I shouldn't but nobody answers me there:
I have a sapphire r9 290 which doesn't want to move the memory clock from 150 when mining darkcoins, leading to 1/10 of the available hashrate. All other cards are fine, and the card mines fine with other miners (engine clock can be changed instead).
Please help!

This fork for cpu mining only?
there are gpu miners, but not very convenient. an r9 290 does about 2x a big cpu. |
|
|
|
|
I can't get a decent darkcoin hashrate with my sapphire r9 290, while the other cards are ok.
It looks like the memory clock stays at 150 no matter what I do.
Any advice?
EDIT: if I run another miner after this one, the problem persists even there, until I reboot.

I have an idea which would be uber-cool and most probably not TOO hard to implement: "Pay-out and switch pool" (short POASP).
With POASP, my account settings would have a limit for the currently mined currency and a select box with the available pools (like you already have for pool-switching.
I would enter a limit, the pool to switch to, and once the limit is reached the system would do a (complete) payout for this currency and switch to this preselected pool.
And because POASP would be a currency/pool-dependent setting I could do this for other currencies as well.
Choosing a fixed pool to switch to doesn't make sense. It would need to be an automatic choice based on difficulty, block reward and maybe something else. So first make automatic switch; then different trigger conditions (including payout threshold) can be implemented. |

I believe there are a couple big botnets mining different coins based on their difficulty: they jump to securecoin when diff is low and bring it up, then jump away. |

Please point some hashing power to a Scrypt-N coin as it seems to be beating all of the plain scrypt coins right now. I just jumped ship from middlecoin, hascows, multipool.us etc. over to Trademybit - https://pool.trademybit.com/home/. I believe they are the first site to have PANDA and VTC on a switching Scrypt-N pool. Your card will get about 45-50% less hashing power doing Scrypt-N compared to normal scrypt coins With right around 500K (So 1Mhash on plain Scrypt) I am easily doing over .020BTC per 24 hours for the last few days You could get autopay in BTC but that costs you 2% in fees, so I just setup an autopay out to Mintpal and Crypsty Interesting, I was looking for non-scrypt-non-sha256 multipools and this is the first. What mining software are you using? A modified cgminer for scrypt-N? |

Try putting a fan (at least 12cm) right at r290(x) side (near the card fan, 90 degrees to the mainboard), blowing in the card direction. Helped me reducing the noise greatly (it also reduced power consumption, the r290 fan sucks a lot of electricity when turning fast).
Not enough room to do that on my rig. It's not on a tabletop, rather in a desktop tower case. The 290X is on the first (physically, the upper) pci-e slot and the 260X sits below it on the second pci-e slot. Out from the end of the 290X, the hard disk carrier occupies the rest of the space to the front of the case. I point a fan at the side of the tower case. So the fan is parallel with the motherboard blowing fresh outside air at the top of the cards and their fans suck that in. I think that might be what he meant, putting an extra fan blowing in to the existing card's fan doesn't make any sense. I think he meant putting a fan near the front of the case, blowing across the top (side without a fan) of the 290X. But in my tower case there just isn't room. I have an 80 mm fan arranged as you suggest, blowing across the short dimension of the cards onto the motherboard (the side case cover is off). Exactly. The other configuration (parallel to the mainboard) has proven to be much less effective (at least in my case... And in my case he he ;-) ) |

to turn the 290X's fan down from jet-taking-off to kitchen-stove-fan, so I can hear myself think. This brings hash rate down to 520 or so. And then when I go away
aticonfig --odsc 1000,850
for normal speed of 600-640 MH/s.

Ehmm.. any info about the smalltime miner maxcoin pool?
No idea. Pools seem to be accessible at 162.243.123.200. I wish I could connect to max.smalltimeminer.com with this ip, but I don't know how to do it. edit your hosts file (google it where to find this file on your computer) and add the line 162.243.123.200 max.smalltimeminer.com this overrules DNS and always points max.smalltimeminer.com to 162.243.123.200 from your pc. but dont forget to delete this line after they fixed their issue, or you might get problems accessing max.smalltimeminer.com in the future! this will not fix their web server... if it's not accessible by the ip, it will not be by the name, this way. |

why clever mining says 0.01247 per mh but waffle only 0.00951912 per mh  ? maybe clever is doing better now (but what counts is a longer period), maybe they are calculated differently... doing your own comparison and math is always the best way. |

If it's set as a name-based virtualhost, then you're out of luck. Unless it's available as a subdirectory of the main web space: try to look into your web history in order to find clues. I never used it so I can't do it myself. |

Thank you, great support!

erebor (MAX) is going up and down repeatedly.
The servers are always online, cgminer works without interruptions. Meanwhile ascertained, there is a problem with win version downloaded from 1gh. This is NOT the server problem, but false client. Our windows client will be ready soon. I'm on Linux and compiled cgminer myself, works fine on 1gh. Maybe there is something specific I should do when compiling it for this pool? |

was curious about the diff as well. i run 280x cards. what should it be set to?
It depends on the total hashrate of the rig, not the single cards. And it actually matters very little in the long run; I'd stay with 256 or 512 if more than 5 Mh/s. |

0.011 a day for 800 Kh/s is very good! O_o |

Hello!
Sorry if this has been asked before, but is there a way (or is it planned) to set a different payout threshold? I mean something like using WALLETID_payout as username.
At the number of payments we are currently making, we cannot make it lower than 0.5 MAX (or our transactions would not fit in blocks and would be lagging behind more and more). Increasing it probably does not make sense either. What is your usecase for changing the amount? When I can't exchange manually for some reason (like when on holiday), it's useful to have auto-sell, but it requires a minimum deposit of 1 coin. Is it that 0.5 transaction is not credited to your account instantly or that it is not autoselled until the account reaches 1 coin? Because in the latter case it would be autoselled as soon as another 0.5 transaction comes in, or is it not true? unfortunately the single deposit transaction must be greater or equal to 1 coin. |
