I'm having a strange behavior under linux
Using the silentarmy kernel, with 2 470 8gb cards, 4 threads, 15 sol/s/thread
Using 3 cards, it goes down to 12 sol/s/thread
Using 4 cards, it goes down to 9 sol/s/thread
The cards have edited bios with 1750 timings copied to the 2000mhz strap
What may be happening here?
I'm using ubuntu 16.04, last 4.4 kernel, amd gpu pro 16.40, sempron 140, 8gb ddr3
Best regards!

mostly stable for me  RX 480 8gb reff Rx 470 4gb nitro Care to share the nitro bios and polaris/wattman screen? Thanks mate, very nice results, do you know what is your consumption@wall? I'm using this bios to get around 28 mh/s also https://forum.ethereum.org/discussion/9533/28mh-470oc-nitro-4gb-boysie-rom-dual-mining/p1Works pretty well but you have to set the dcri to a specific value to really get that numbers. I managed to get 29.2 mhs + 450 decred/sia getting the mem to 2060@1.15 and core to 1260@1100 trying to use your setting but i get the blue screen, seem imposible, are you increase the voltage? power limit + ? Your mileage may vary, after a while my setting wasn't stable enough anyways, depended too much on the power limit, etc. etc., i'm currently on 1300@default voltage clock and 2000@default voltage mem and it's pretty stable on 27.5, i'll wait until i find some way to correctly manage voltages under linux and the fine tune to see if i can get 28 stable, i don't have power consumption issues so i prefer better speeds. |

I managed to get 29.2 mhs + 450 decred/sia getting the mem to 2060@1.15 and core to 1260@1100 OC nitro? Is that just the same as the nitro or are there two different nitro's?  Oh yea, and as i understand it is better to save stock bios with polaris bios editor than gpu-z? And i can use atiwinflash while using integrated graphics, right? Sapphire RX 470 Nitro+ 4gb i always use atiflash from the command line, the only time i tried to use the ui version atiwinflash it hanged up and i had to unbrick the card flashing the bios using another card as primary to be able to boot. If your itegrated graphics allows you to have another graphics card working it'd be excelent, on this old p5qm-em the igd doesn't work very well when last gen video hardware is attached to the pciex, so i had to use another card on the 16x pciex port and the bricked one with a riser on one of the 1x  . Glad it worked, when playing around with bios flashing you're always risking bricking the card for good, so be careful and be warned! |

afaik the rated voltage for eg. samsung memory at 2000mhz is 1.35 volt.
Older gddr5 chips were normally 1.5 or even 1.6 volt.
So setting it to 800mv without crashing is a sure sign it doesn't work.
Which is a pitty because most performance could probably be squeezed by upping mvdd. (not vddci)
Yeah, I tested myself and I do believe you're correct. It does seem to work on Fiji, IIRC, but probably because HBM. Mentioned this a few times already, but i'll do it again  Fiji and Those Lightning cards are the only ones capable of directly modifying the memory voltage (MVDDC or how it has been referred here "MVDD"). For every other card out there (i could have missed one or two) you can only raise or reduce the voltage given to the controller (VDDCI/AUX). This isn't even stock, to be able to do this, you'll need to add the needed offsets in the rom, therefor also needing to remove extra whitespace in the rom to get the exact same size again. Not only that, the tables in the rom have to be modified as well. i2cdump ... So basically, at this point, by opening polariseditor or wattman or whatever, and changing the voltage value next to the memory is not going to apply directly to the memory, but to the controller, so basically, giving that controller extra voltage does not affect your memory directly as that memory isn't getting extra voltage. Could we just change vddci in Linux using pp_table? After parsing it seems vddci is there: Container: ucRevId = 0 ucNumEntries = 2 ATOM_MCLK_ENTRY = [ Container: ucVddcInd = 0 usVddci = 850 usVddgfxOffset = 0 usMvdd = 1000 ulMclk = 30000 usReserved = 0 Container: ucVddcInd = 15 usVddci = 950 usVddgfxOffset = 0 usMvdd = 1000 ulMclk = 220000 usReserved = 0 ] This is only for the controller, and other shit (AUX voltage.) Tested setting values for vddci other than 950 for mclk 2200MHz. Immediate crash. I'm finishing up testing on my tool for this, and it will do 900 - 1000 for me, but 1025 is too much (NSFW): https://ottrbutt.com/tmp/wolfamdctrl-v1-testing.pngCare to share src? I've been playing with pp_mclk_od and pp sclk_od, but setting up voltages would be awesome! How do voltage mod work with normal amdgpu-pro drivers on a 4.4 kernel? Thx! |

Wonderful!! Well we have some good news.
PressTab is now available to do our work.
This is extremely good news.
PressTab was our preferred option by far - for many reasons.
Will report back as news comes to hand - I will advise the community the scope of work, cost and delivery.
We can discuss then.
Cheers - usukan

Such a nice community! Lets get this thing over 1000 satoshi  I bought part of my current investment over 1500 satoshi's... i don't remember anymore but i think even 3000 I would not sell it under 10000 satoshis, period. Let's see what the price may be! |

I couldn't find any way to correctly mine yacoin with current radeon drivers, maybe older drivers work better, but with crimson ones it's not working or it works only very slow.
May be it's time to update yacminer?
I don't have a problem. What are your settings, hash/s. Who are you talking to? Nobody in particular, just saw someone with a similar problem as me in the previous posts and just stopped by I tried the same settings with the same card and obtained the same hashrate, but i have gtx 970's giving around 400h/s each, how can a r9 290 give just 20, and there are 2 problems, 1) we can't set the full 4gb of the card with the --buffer-size param, it just won't alow us to set up more than around 2800 mb, so that reduces the amount of lookup tables that the kernel can use to speed up calculation, and that leads to 2) superslow hashrate with every setting we try that works. One technique with high shader cards is to setup a very high lookup gap so the shaders can be used for calculations and some times that rises hashrate in opossition to trying to use the maximum amount of memory for lookup tables. That is not giving good results, however i remember having done that with 13 and 14 versions of the radeon drivers. Best regards! |

Is there anyone willing to ask Bter.com to fix the YAC deposit problem? I think currently Bter.com is reliable for they are running the service for a long time after the previous attack.
I have, their response has not been very helpful Dear Sir,
I am so sorry for the inconvenience caused.
The YAC wallet doesn't work well currently. We are working on it
The address will show as soon as it works well again
Thanks for your patience

So strange to see as bagholder, i have arround 997.000 UTC in my wallet and it has now no more value as arround 4,2 BTC  
Does have the UTC management team or some serious community members a vision for 2016 about the potential development of value of UTC ?I second this, i just can't buy utc anymore as everytime i buy some, the price drops again, and again, so... i think that utc value should be improved somehow... |

Not yet, but the hour difference is way too high, let's see how the net works on this situation (really a nice net test ) 1k thanx, i'm gathering a small utc fortune bit by bit, let's see if the waiting pays off Best regards! It's pending, but the net is being slow at the moment. It's really bouncing too much, the amplitude goes from very low (and exploitable by opportunists) to very high (and discouraging the normal miners) I think the adjustment should be faster if the difference between the needed block time and the real block time is way too high, and slow if the different is minor. |

Well, as it seems, the diff bounces with too much amplitude.

it appears that in another 60-80 blocks the difficulty will return to normal the shape of the graph for decrease continues to be a mirror image so far of the increase in difficulty http://imgur.com/Z6YiSCNbe aware the timescale (block number) runs from right to left (left is most recent). staking is now working again just fine too FrickChick, argencoin and meebo (on alenavaa's pool) - if you post a deposit address I will send (at least try to send - good test of the network) you a 1000 UTC each as a token of the community's appreciation. Cheers - usukan Yeah its a prick to have your miners hashing for bugger all - brings me out in cold sweat whenever it happens. Those who supported the mining in the darkest hour - I really take my hat off to you. Offer still stands - just post your deposit address FrickChick, argencoin and meebo (on alenavaa's pool) - if you post a deposit address I will send (at least try to send - good test of the network) you a 1000 UTC each as a token of the community's appreciation. On and up and down and UP!  UaudboCoV45anf7uXXDyBdh8etw8e7V7vu I'll buy a cheap NF14 only rig next month just to mine utc (4x r7-240) Best regards! |

0.28! Go speed racer go! |

Would be nice to set the stratum diff back to normal, 4 is a lot and right now would be the same as there will be blocks every hours not minutes, but with a high diff there is a lot of gpu power wasted on restarting works everytime a new block is found.

Im turning back my rigs to pool.
I hope some other guys can do same and we help to adjust diff sooner and we will get back to normal.
Lets mine guys!!!
Ok, here i go too. Don't know why i'm doing this, UTC has been steadily dropping for a long time now without any real development, but oh well, i like this "rescue" moves All systems operational and mining utc. |

The difficulty is still increasing even after 17 hours between the last two blocks.
If you graph the difficulty - its still heading towards the stars but on the bright side the increase is linear - not in an exponential phase in other words the rate of increase is constant - not accelerating It was exponential until about block 1600280 Good news! Difficulty has turned the corner and is decreasing............ Just how fast it will come down is the question? - and will it over-correct at the bottom? Last 50 Blocks Found Block Validity Finder Time Difficulty 1600294 548 left meebo 11/12/2015 00:50:45 0.3768 1600292 546 left anonymous 11/11/2015 17:17:32 0.4081 1600290 544 left meebo 11/10/2015 23:51:53 0.3663 1600288 542 left yacoinben 11/10/2015 20:19:21 0.3223 1600286 540 left yacoinben 11/10/2015 18:37:10 0.2836 1600284 538 left yacoinben 11/10/2015 17:21:43 0.2496 We'll have to see how it behaves after dropping to normal levels, but it's wonderfully happy that diff is already decreasing! |
