Hi, I have two Vega 64 cards with a R9 290. I was using the blockchain drivers previously and was obtaining 44Mhash/card at 130w by applying a registry tweak and OverdriveNT to lower the vcore of each card to 0.8125v. I just updated the driver to 17.10.2, and while I can easily obtain 44Mhash/card, I cannot get the voltage back down to that level.
I have fiddled around in Wattman. I have lowered the core clock from 1000mhz all the way down to 870 without getting the lower voltages. I have tried autovoltage and manual voltage combinations. For the manual voltage combinations I have tried changing the vcore voltage and the HBM voltage in many combinations, such as vcore/HBM 850/800, 800/850, 950/900, 900/950, etc. I have tried lowering the power limit. I have tried combinations of these changes and the best I can get is with lowering the power limit and vcore, I can get to 0.92vcore.
The registry tweak I used before makes my computer not boot into windows.
Anyone have any idea how to undervolt Vega64 to 0.8125v using the 17.10.2 drivers?
what too are u using to check if the voltages are correct ? I have three vega 56 with 64 bios seems they can do 1105 mem and 38 eth and 150 lbr or 40 eth solo the core voltage says .91-.96 in GPUZ , you were getting lower voltages ? I have the same drivers as you. Also on two cards only half the red lights are lit up but on the other one all the lights are lit up ? wtf ? |

Just scared of viruses , thanks I apreciate the link |

Hello everybody!
I have an issue, I can' t start the EthDcrMiner64.exe, it crashes and auto-delete, there is no way to run on User instead of Admin? it request for admin privileges
any solutions?
turn of windows smartscreen then add an exception for the claymore folder in the windows antivirus |

confirmed the wind 10 64 bit new drivers work for 10+ cards
... since I cannot set the voltages on this mortherboard
the ASUS 16 Slot one with MSI AB
Try OverDrivenTool you have a link? |

By longer you mean >3 years for eth?
They'd be long gone to PoS before 4GB cards aren't capable enough in mining ETH.
I don't sell my cards so i'm okay with 4GB.
theres other algos to mine though that will hit the 4GB limit in 2019 but i get what you are saying if u never sell cards |

works for me with 10 with new drivers atm

I have a 10 GPU rig running now, what I did find is uninstalling afterburner first helps
also with so many GPU it would also sometimes hang on when u run claymore, I fixed this by using -gser 2 option
It still hangs when i try and dual mine so I need to do more tweaking.
ALso AMD settings and MSI after burner do not play nice togther, I decided to roll with wattman since I cannot set the voltages on this mortherboard

WoW! Prices have certainly dropped on the RX580's looks like the mining bubble is starting to show signs of deflating. Hope these are in stock and not just on back order. That’s a good price. But if a Gaming X or Nitro+ is available too with a slight price difference, i’d take these rather than the Power Color ones, as they have poor cooling. I got 4gb Rx580 Nitros last week in Newegg as well for only $302cad or $235usd. Eight of them 😆 I know 4gb cards are cheap but i prefer 8gb since they have better resale and can mine eth etc or ubiq longr |

but the driver is slower than blockchain driver?
because i put in on a computer 1x rx570 when blockchain driver won't run, no idea why, driver install correctly but miner close at start, looks like something is missing
i tried manually install driver, and a cleanup driver but something wrong
i have the same problem on my computer with an r9390 blockchain driver won't work
i put 17.10.2 but it s very slow 22.8mh only dual mining, lost 1mh compared to previous driver i had
i heard there is a setting on the new drivers under global where you have to flip a toggle for compute workloads so that is probbaly why you are seinf a low hash rate yup just tried it and one hour in the new drivers are good for now at least, only issue is u have to pick compute workloads for each and every card , one plus note is i can now change the voltage settings now using wattman , when it would not work in AB wierd |

whats goinng on with ATM chain ? no offical thread for it but its up 300% today
Just came on to ask about it, though I see that it's in the green 93%. I wonder what happened there. If all the coins were in circulation it would be in 17th place in market cap. yeah whats goin on with the coin release how much are they releaseing to the buyers , i dont think i got all the ATM i bought |

I loled  |

They have a poor rma policy . Do not admit you mine. I had the rx480s they had two models one was very good, Let me look. The red devil was the good one the red dragon was meh yeah i love the red devils |

Relase note mentions up to 12 GPU for compute workloads possible. I wonder if this includes HBCC My vegas are in the mail so cannot test myself yet. Win10 fresh install. After installing new drivers all cards remained as Basic display adapters in device manager.  So, installed 23aug blockchain drivers instead new ones. look for the 17.40 drivers they say beta but the work great on my 3 vega rig 40 eth 150 lbr with 1090 mem |

Someone have tested jet NEW AMD 17.40 drivers for vega? What about hasherate on eth?
Almost as good as BC driver. 0.5-0.8MH/s slower than with BC. But you can adjust clocks and voltages in the wattman. yup i tried these as well since with blockchain drivers i could not turn off crossfire which was throttiling the other vega card. I plan to update all my AMD rigs to this new driver |

careful buying this board btw on windows 10 you cant undervolt with this board, i have tow 8 card rx580
same issue on this board

Im not sure, 2 RX 570 its about 230W and this is 55 Mhs, what about Vega 56 ? 39-43Mhs and what about power consumpiton?
Vega 56 can do 44mhs eth @ 150watt (1220/1100@820mV) or 1940h/s XMR@150watt (1408/1100@875mV) or 43mhs eth + 200mhs lbry @ 210watt (1220/1100@820mV) 2 well tuned polaris cards are still better then 1 vega56 for ETH but vega is better in xmr and dual-mining how do you change the mv on polaris, i can get to 1100 mem on vega 56 but cant change the voltage to allow dual mining Did you mean Vega, not polaris? You can downvolt Vega with softpowerplay reg mod if you have aug23 blockchain drivers or with regular tools (overdriventool + afterburner) if you run recent amd drivers polaris cards have never had issues with downvolting, with my vegas in after burner with the lastest. blockchain drivers the voltage slider is disabled like it is for nvidia cards even after i enable voltage overclocking and underclocking like i have always done on m polaris rigs why would have to do a registry hack to undervolt ? Never had to do that on my polaris rigs on the AR 270 asus board |

1070 solo mining ahould be 181 mhs
eth mining speed is the same no matter if you mining solo or on the pool. Im saying a six gpu 1070 rig is 30 mhs per card or 180 i have 10 differnt brands and they all mine at 30 mhs unless im dual mining learn to read |
