hmm..
I have problem with 4.1 version
I have 4 cards on one of my rigs
r9 280x
r9 280x
7970
r9 390x
i adjust core clock for each card in msi afterburner, but when i start miner 390x downclocks to around 950 MHz, this is not throttling because temp is blow 70C for all cards!
In my rigs, using 270x and 7950, every time I use Afterburner to change some settings I always restart the system before starting the miner. This way, I make sure the settings are permanent because I double check they are in effect before firing up the miner. It works for me  |

Miner shows GPU temps and fan speed every 30 seconds if you specified "-tt" parameter to manage fans.
I will add "-tt 1" that will not manage fans but will show temps and fan speeds.
As it is now the -tt parameter works perfectly! |

Version 4.1, like all previous ones, still uses a weird ID scheme and it can be a bit confusing when the miner's GPU 0 is Afterburner's GPU 3 or something like that.
Check my explanations: https://bitcointalk.org/index.php?topic=1433925.msg14659010;topicseen#msg14659010So there is no way to fix GPUs order automatically, thanks to AMD devs. But you can do it manually. For example, if you have two cards, you can change their order by adding "-di 10". Another example, reverse order for six cards: "-di 543210". Ok, not a big deal. But like I said, it can be a bit confusing on a 6 card rig Guys, whats is the highest value for -ethi that gets you optimum results?
I'm currently using -ethi 16 and I can see a slight increase from the default value (-ethi 8 ). However, when using -ethi 32 or -ethi 64 the miner will report the same total speed, apparently not getting better results.
Any ideas?
check the log. 16 is the highest value, Really? Ok, thanks! |

On my R9-390 - - dcri 60 got me 870 MHs, and I took out settings for -ethi to none (leave it to CDM to manage), that got me to 29.2 MHs (with -esm 1 settings). The R9-390 has OC settings of -100Mv, 1020Mhz and 1500Mhz for core and memory respectively, using Afterburner utility, Catalyst 16.5.1 Thanks for your reply but I'm just interested in -ethi settings. Concerning DCR, I'm using -dcri 30 and everything is fine but ETH is my priority |

Voted! TEK now leading |

I've been using this miner, testing all versions as soon as they are released and I'm very happy with it. My wish list: - Power control/limitThis would be a very handy feature for those who have to pay electricity bills  - Proper GPU IDVersion 4.1, like all previous ones, still uses a weird ID scheme and it can be a bit confusing when the miner's GPU 0 is Afterburner's GPU 3 or something like that. Anyway, keep up the good work Claymore! |

So, I''m not sure if anybody else has experienced this, but I have noticed a rather large difference in hashrate when using -allcoins 1. Before, on my single 270x sapphire, I was running ~12.5-13 Mhs for Eth and ~180-195 Mhs for Dcr. After deciding to give EXP+DCR a go, I had to enable -allcoins 1. Now suddenly I have 16.69 Mhs for Eth/Exp and 250 Mhs dcr... both absolutely stable.
Obviously I'm not complaining about the gain, just confused as to why? My current theory:
When using allcoins, the DEVFEE is taken from the default pool list in the included txt file. These are pools the dev already uses, and therefor withdrawls would happen more often, making the fee more liquid to the dev and making min withdrawl easier to reach. I assume because of this we get an extra boost to speed?
You are mining ETH at 16.69 MHs with a 270x? Can please elaborate a bit on that? I have six of those and only one goes above 15 MHs, the rest runs at ~13 MHs |

another maybe stupid question, which is the recommended -dcri value for one 7970?
There are no magic rules; you have to adjust your value to your pool and find the settings that will produces less rejects. I use -dcri 20 for my 270x and 7950 rigs on suprnova and I'm getting less than 1% rejects. |

With v.4.0 DAG creation is fast and stable, well done! same speed for me, is a real gain using -ethi 8?
I'm using -ethi 16 and it improves my speed a little bit |
|
|

If you are still sure that v4.0 is slower with "-ethi 16" option on epoch #47 than previous versions on same epoch - PM me logs for both versions so I can check the reason.
v4 is working flawlessly on my rigs and on my PC |

After six hours. Still working rock solid, in the cold systems room. Many thanks Trimegistus...  Good news! You're welcome |

BTW this CRC check is way harder for low-end CPUs, while creating DAG mining is almost at zero hashrate(95-99% less than full speed), with previous versions it was mining with 30% less hashrate.
Yep, this is my only complain about this new version. My rigs use Celerons G1840 and they have a hard time computing the new DAG, reducing the hashrate almost to zero  But once the DAG is complete... my rigs don't freeze, don't complain, don't moan...they just mine! |

With ethminer system is working without PC restarting, using Dual Miner is heating up the cards more ? because it's dual mining ?
May be I missed if somebody already mentioned this?
Dual mining significantly increases the workload on your video cards, therefore they will generate a lot more heat. |

Hi,
first, thank you very much for this wonderful miner.
This is being one of the best miners...
I have a 5 card rig and individual pcs with single cards inside arround.
I have no problem with single gpu card pcs. They mine wonderfull.
The problematic 5 card rig,
PC mem was 4Gigabytes. Now 8. and I moded to enable 5th GPU.
the 5 card rig, with 3.2 miner, PC RESTARTS after dag file generation and approximately after 10 minutes of hashing.
Now I'm trying the 3.3 version. Hope it's not the low memory (8GB).
With Ethminer system works just fine. without crashing.

Is there any way you can program if the gpu temp reaches let's say 80 degrees celcius, slows hashing to keep the temp at 80
I have card 86 degrees fan is %100
Claymore you are doing a good job
Thanks in advance
I have two 6 card rigs mining flawlessly with Win7 x64 8Gb system RAM. Your problem has nothing to do with low memory but with excess heat. If your cards are at 86º and fan already at 100% you have to improve your cooling. Try adding extra fans. I use a small USB fan to push fresh air from bellow and two 120mm fans (connected to the motherboard as case fans) to pull the hot air from above. I use the -tt 75 parameter and my cards are always around 72º with fans ~60%. |

I'm mining at 1600mh in the miner console... but decred pool keeps showing lower hashrate and lower payments. according to calc i should be making: 1.26. i'm making around 0.9x ... should i just move pool or could it be something with the miner? thx
I've been getting accurate results in suprnova  |

I used to mine with Ethos, now claymore seems to be available only on windows. Does anybody have any idea on how much RAM I need per card ? Most of my rigs are with 390s. The good thing about Ethos was that it was running fine with only 4Gb of RAM for a 6 card rig and not even consuming all 4.
To mine ETH you need a minimum 2 Gb RAM per card, otherwise the DAG won't load into the cards's memory That is actually incorrect with ethos my rigs of six 390s run perfectly fine with only 4Gb of RAM on the system. About 2.9 is actually used. Ethos is really striped down Ubuntu distribution with anything not needed for mining removed. Great job by developers btw. I meant 2 Gb memory in each card, not in the system. Yes, you can mine with 6 video cards having only 4 Gb system RAM if you use one of those special Linux flavors. Under normal conditions, even with Ubuntu, I believe 8 Gb system RAM would be a safer choice. But every card must have a minimum 2 Gb video RAM! |

is this normal or should i try the -esm 0 command? thx
From the OP: -esm Ethereum Stratum mode. 0 - eth-proxy mode (for example, dwarpool.com), 1 - qtminer mode (for example, ethpool.org), 2 - miner-proxy mode (for example, coinotron.com). 0 is default. If you are not using the -esm parameter, you are already in -esm 0 mode. |
