anyone using Sapphire 280x vapor? im getting only like 19Mh on those aint that to low?
mine is ~20MH ETH and ~300MH DCR 1100 cclock and 1375 mclock don't forget this on your .bat GPU_FORCE_64BIT_PTR 0 GPU_MAX_HEAP_SIZE 100 GPU_USE_SYNC_OBJECTS 1 GPU_MAX_ALLOC_PERCENT 100 GPU_SINGLE_ALLOC_PERCENT 100 I didnt forget it, altho i was running it on stock settings that is 1070 cclock and 1550 mclock or your 280x had elpida RAMS, read about the performance issue with that compared to 280x with hynix RAMS many months ago. mine is hynix BTW. that would explain it, i have elpida on them altho i changed clocks now to 1100/1375 as You suggested and its pulling 20mh now, thanks! read sometime ago that the hynix and elpida issue is a non-issue for ethereum mining, that would explain the 20mhs on both our cards, i think.. |

So I had to post up here and brag on Finksy. Even after offering bounties (which I still have to pay and will) by FAR he was the most helpful in getting me up and running using just the server PSU's for GPU mining. They are loud but I have FAR less trouble out of them than consumer PSU's. Also if you want to make them quieter it's pretty easy to build a box with mattress padding to cover the front (leaving the back open and not suffocating the fans). After making my own wiring harnesses it runs like a charm, they stay cool and the 12v wires are extremely substantial (I'm delivering 200w per wire and running 2400 to 2600w per PSU). You won't regret dealing with this guy.  what wire did you use to extend your GPU power cables? i guess it is modded using stranded wire? |

my 390s rig does not show in suprnova for a while now..only DCR hashes in the miner are there... no "DCR share found" or DCR share accepted"
while the 280x rig is okay.
PM me zipped log file please. will mine for about 30mins again in dual..and send you the a fresh log..(because i switched to ETH only, got lost in a lot of log files) off topic: you might want to take a peek at equihash POW you can't be late for this https://bitcointalk.org/index.php?topic=1438066.new#new |

There is no publicly available optimized code for Equihash, so we don't really know to what extent it is bandwidth or latency bound. There may be subtle trade offs between the two. We really need to see the memory behaviour of actual running optimized code. Even once zcash gets around to publishing more optimized cpu and gpu code, it won't be clear for a while whether further optimizations are possible, considering that the mining algorithm is rather nontrivial. I'm somewhat worried by this statement on their optimization page at https://github.com/zcash/zcash/issues/857We don't have to do every possible optimization, but enough that it's feasible to run a miner with the right parameters.
Leaving optimizations on the table means that some miners will be able to run more efficiently than others.  |

after running v2 for whole day...
I noticed my GPU temp shot up to the normal mid-70s to 95c!
is this normal?
check your GPU thermal paste and GPU fan for problems..mining DCR adds more to GPU core temps..thermal paste tends to dry faster under this situation. my temps didn't change much here |

watching my rig mining in dual mode..it seems that DCR shares are getting fewer, almost none in my other rig (only at the beginning of mining DCR shares appeared)...watching in suprnova dashboard my rig with almost no DCR share (with shares at the beginning of mining) is gone (not submitting shares)
it seems my 5870 ~800Mhs solo mining with sgminer is outperforming the DCR dual mode that generates 1300 to 1700 Mhs for DCR mining.
the rig with 3x r9 390 and 1 390x stopped submitting shares while the rig with 4x 280x is okay i think..
that's why I asked about dual mining earlier with coinotron (ETH) and suprnova (DCR).. the rig with 390s have hashes but not submitting shares
EDIT: my rig with 390s with ~1700 Mhs submitted shares shows up on suprnova with 7300 Mhs after being gone for a while...will observe more for a longer period of time...

Claymore, I'm a little curious as to how the developer fee is applied in a rig with multiple cards with some GPUs restricted to mining Ethereum only and was wondering if they were taxed 2% just like those mining Ethereum as well as Decred.
Thanks!
from OP This miner is free-to-use, however, current developer fee is 1% for Ethereum-only mining mode (-mode 1) and 2% for Ethereum+Decred mining mode (-mode 0), every hour the miner mines for 36 or 72 seconds for developer.
Decred is mined without developer fee.
If you don't agree with the dev fee - don't use this miner. |

@arielbit Yes, Dual stratum: EthDcrMiner64.exe -epool coinotron.com:3344 -ewal user.worker -esm 2 -epsw x -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal user.worker -dpsw x -allpools 1 thanks... played with the syntax earlier..it run but the DCR hashes didn't show on suprnova... will continue testing here. EDIT: WORKS!  |

is coinotron and (stratum DCR) suprnova supported in dual mining?

lol so you thought the molex and usb slots on the riser board were for whatever option you felt like using? |facepalm|  glad you sorted this one out. that does sound like a low hashrate for your card configuration  well, the board has 2 4pin molex on it which I have connected to the PSU. Plus, those cards also have dedicated power from the PSU, so I figured connecting the power on the risers wouldn't really be needed. Owell, lessons learned. lol, 16x slots have more power because some lanes in the 16 lanes are power source, that's why those 1x to 16x adapters needed an external power source going through that sata adapter. maybe you can try claymore's dual ETH, DCR miner..i think you might like it |

decred.... what's going on?  ? You mean because the price is falling? Have you ever seen a stock that only rises but never falls? New DCR are being produced through PoS and PoW and nothing new is happening yet, so of course the price will slowly decrease. Once the GUI wallet is finalized and the coin is listed on more exchanges (like Poloniex) the price will go up by a lot ( IMO). Now is the best time to buy. Blablablabla GUI wallet is something new in crypto world? Something that makes you screamin WOOWW! I know many people waiting for GUI wallet only to dump easly their airdrop. So maybe, a GUI wallet will maked dcr decrease and dead even more. Poloniex? Eth was listed on poloniex after 2 days from launch. Decred after 2 months not. So, maybe they are not interested. The rest is only hype. Don't get me wrong. i have decred,but at launch i saw team much more enrolled with the coin. twitter advocate,promotions,crypto article,facebook advertising. Now they seems doing nothing....just fixing stuff on code. So, why they begin making all that hype and now they say "we don't invest in marketing?" Explain please... Your coin mister decread team have much selle pressure then buy pressure. So,you have to take care of your coin and price. you just cannot say: we're working on code, we don't give a shit about price. Your product have a value that is slowly decreas,you have the right to take care of it and recover quick. It's also in your interest..... Don't forget that lisk,slock,zcash and other project are coming. So,you need to be competitive to not lose interest. The worst thing Decred could do right now is bring a ton of hype to something few people can use.
ETH price increased when people felt they will have use because DAPPS are being developed etc. in my opinion it is better to speculate in what is the lowest entry price you can get.. until decred delivers something new or innovative or something we think will have a use, that will be the time where we can see a real price increase.. the higher the risk, the higher the return. until then just educate ourselves, do research, develop our instinct so we can lower the risk using our brains. good luck there |

HI I am a new to dashcoin, and i just install my wallet and want to make transaction and i am confused what to do with id payment, can anyone explain to me how can i know what is my id payment or how to find it please thank u you can send coins without using payment id, if you will send coins to poloniex exchange, payment id is required though.. haven't generated payment id for myself...anybody who can teach how? If you mean a new payment ID in poloniex, they have disable that possibility. no, I mean generating payment ID from my PC, using our dashcoin wallet...I believe this is what NEKOGAMI is asking. It's just a random hex string (well, doesn't have to be random, but it is a 64 character hex string). You can do it in a one-line function with python like: # Generate random hex strings for payment id
def gen_paymentid():
return ''.join([random.choice('0123456789ABCDEF') for x in range(64)]) Or you can use this website: https://www.randomlists.com/random-hexthanks..I've read that using payment ID is useful to prove a transaction came from whom, that's why poloniex required the use of this. I think it would be useful for the GUI wallet to have a 64 hex character string generator and in the address book too for record keeping. @ NEKOGAMI there is your answer. |

Ok, thanks for the confirmation. I first tested it out with just one 390x connected via 16x riser, and that worked great. Then, I installed TeamViewer, shut down, connected the other GPUs via 1x-16x risers, and restarted (without a monitor plugged in. I thought I could just then use TeamViewer to connect and start up the mining software). After work, I'll try restarting again but with a monitor connected during bootup to see if the other GPUs get started.
I've got 2x 1000w platinum PSUs to power the 6 gpus. Should be enough. While testing though, I've only got the 3 connected with 1 of the PSU. I think 1000w is enough to power those 3 cards though...
No Prob. The 390x's shoudl draw stock about 250watts each, the 280x's about 230watts or so. (as long as they are good quality cards). 'Most' 390x's you can undervolt and get back about 10-20% wattage, some more, some less. I run all my 390's (non 'x') at 100mv undervolt, 1100/1500 settings (stock is 1015/1500) and they use 200-210watts each while getting around 29MH+ now. Solo mining has been earning me 50% more than pool mining for the past week so I'm sticking to it. Some days I get 1, some days I get 5 blocks. Well shit. So I got home, plugged in the monitor (with all 3 gpu's connected, 2 via 1x-16x risers), and booted. Still, only the one connected to the 16x pci slot powers on and is recognized. I've got the molex power connector on the mb plugged in, and all 3 gpus have dedicated power which I made sure what all connected. My PSU is an evga "supernova", so no issues with psu quality I think. I know it's not the gpu's because I swapped out one of the ones connected via the 1x-16x riser to the 16x-16x riser, and that one powers up just fine. Only the ones connected via 1x-16x. Anyone have tips for how to troubleshoot this? Edit: MB is an ASROCK H81 pro btc, 2x 280x are both Sapphire, 4x 390x are all MSI. i'm using windows 7 64bit 1x to 16x risers old 80gb hdd's , 2gb ddr2 RAMs good old socket 775 cpu's and motherboards @ 4 cards each. all fine, i'm using only one monitor that i plug if remote access troubleshooting is not possible. sometimes it is better to have at least two rigs, a few extra risers and a spare PSU that you are very sure that is 100% working. swapping components to compare and check to know what component have trouble. from experience i've seen motherboards that cannot detect more than two or three GPU's (know that i'm using cheap old boards), there are two 1x to 16x risers here that makes my gpu's undetectable (this have been used for quite a while). it is also good to have a GPU temperature monitoring software around. to know what card is heating more etc. last day one of my miner hanged twice, unplugged my hottest card, found out the my high speed hydraulic fan is not smooth anymore (rotating) (from modded old sapphire 280x), removed the cover underneath the sticker, put some compressor oil (just lying around here) returned the cover, seal it with a piece of masking tape (fan fixed-smooth again)...... and reapply thermal paste to the card because it was already dry.. and the rig was fixed and mining again Ok, I'll try swapping out the risers. The ones I bought are here: http://gpushack.com/collections/gpushack/products/gpushack-1x-16x-usb-riserOtherwise, I know that my MB is a common one used for mining. It's part of the mining series ("Pro BTC") mb's from ASROCK. I guess I'll also try different pci slots to see if that makes a difference. check the review at newegg of your "pro BTC" board , i think someone there have the same issues like yours http://www.newegg.com/Product/Product.aspx?Item=N82E16813157471&cm_re=Pro_BTC-_-13-157-471-_-Producti don't like the design of your riser, the riser should be molex compatible, extension-adaptor wire can sometimes be a point of failure, and the usb wire is kind of short in length. here is one of my rig. the motherboard is mining for me for about 2years now  newegg review or my board  a spare riser..  |
