    My first Vega 64 or any Vega cards, I don't mine with Windows, so lots to learn.

    I want to keep a note of my journey to tweak and mine XMR with Vega 64 or 56.

    Open up the box from Newegg, install the new Vega 64 card in a fresh install Window host ( MSI Z87 gaming board with G1850 CPU , 4GB memory)
    Installed the new AMD beta block-chain driver, custom install , selected to install driver only.
    Windows power option: high performance , disable monitor sleep and computer sleep

    Download xmr-stak-amd window binary , config Windows host to use large-page memory.
    Here is my config.txt
    Code:
    "gpu_thread_num" : 2,
    "gpu_threads_conf" : [
       { "index" : 0, "intensity" : 1932, "worksize" : 8, "affine_to_cpu" : false },
       { "index" : 0, "intensity" : 1932, "worksize" : 8, "affine_to_cpu" : false },
    ],
    "platform_index" : 1,
    
    Start mining XMR , 2000 H/s ( very happy ) :) , unbelievable good hashrate with 1 hour of work

    Things to do:
    try another miner
    tweak memory , power setting , core speed of Vega card.
    check power consumption

    Buy more Vega 64 card when is onsale.

    I am SO wanting to get into Vega GPU mining.


    Edit: Thanks for posting the link to the guide.

    What does the power look like? 2KH/s = 4/day?

    For xmr? More than 50kh/s for 1/day

    Vega 64 with Windows 10 mining XMR stable overnight 12hours , no crash
    Shutdown window machine , hook up Kill-a-watt meter

    Hosting Windows 10 machine power use 50watt
    Vega 64 power use while mining XMR = 300w
    Total rig power use = 350w

    According to
    https://www.cryptocompare.com/mining/calculator/xmr?HashingPower=2000&HashingUnit=H/s&PowerConsumption=300&CostPerkWh=.18
    Using my power company base tier 1 rate $0.18 KWH , profit is $85 per month , $1K per year
    Using my tier 2 rate $0.28 KWH , profit is $60 per month , $728 per year

    EDIT: System been mining for 15 min, power usage actually went down to 340w for the mining rig

    Lower Vega card voltage mod.
    Follow this guide: Monero and Vega - the definitive guide • r/MoneroMining
    Soft Power Play Table at Windows Registry section

    modified 1100MHz HBM @ 905mV reg file to use /0001 folder , imported to Windows system , reboot

    XMR hashrate drop very slightly, from 2,000 H/s to 1994 H/s

    The big advantage is that now the whole rig is using 242w instead of 340w, fantastic payback.

    $0.18 KWH power cost , monthly profit is $89
    $0.28 KWH power cost, monthly profit is $72

    Has anyone had luck getting more than one vega mining at once? I had 1800 h/s on one vega 56, but a second one (using 1x pcie risers) both of them run really slow now (lucky to get 1800h/s -combined- with two cards now)

    From the blog site Vega Mining - A Consolidated Guide
    Mining rig have 2 x Vega 64 and 2 x Vega 56 cards.
    See the screenshot of the rig at the beginning of the post.

    Edit, may be after Black Friday, hopefully, I would scored more Vega cards.

    I do, Vega 56's flashed to 64 bios. I do NOT have them in risers. They are onboard right now. Getting 3500H/s

    24 hours later, system still mining stable.

    Disable windows auto update.
    Enable startmining.bat 30 seconds after system boot.

    Tested auto-start without any monitor or hdmi dummy plug in either VEGA card or Internal GPU port.

    Stick a fork in it, call it done. Start mining for real.
    Won't touch it for another 7 days.

    Todo:
    Power consumption may be still a bit high, according to the Reddit folks, my rigs may be 30w over ideal power usage.
    Since, I have a Powercolor VEGA 64 card, may not able to shave another 30w.

    Not tried on Linux yet.

    It is working so good with Windows , after reading all the Vega card mining issues and voodoo magic on Reddit,
    I am imposing self-control as is not messing it up.

    Black Friday is almost here, hopefully, I could score another cheap Vega to experiment with Linux.

    It seems that Vega hash/$ parameter will kill profitability on many CPUs :(

    With the new Vega card mining XMR, we will be facing much higher Difficulty in next couple of months.
    Enjoy the good time while we can.

    I used to like CPU mining, after experiencing my first Vega card mining, it changed my way of thinking.

    For comparison, I have a rig with a E5 v3 cpu mining XMR at 605 H/s ,
    2 x RX480 doing 1500 H/s , combined 2.1 K H/s , consumes 420w.

    The new Vega 64 took up one PCIe slot, the entire rig consumes 242w ( 50w for the hosting CPU + motherboard , 190w for the Vega 64 card ).

    Edit, Wish there are more Vega card deals.

    I was watching the last PowerColor Vega 64 sale on eBay and out of the 721 units they sold probably around 50%, if not more, went to miners (bought multiple cards). Many were also sold to new users with no prior feedback. So, those were likely new accounts created to circumvent the 3 unit limit.

    Yep that why I am not getting any more open compute servers.

    Damn... I was holding out for some Black Friday goodness on Vega 56, but Newegg is sold out today.
