    Lightbulb !!!WORD NERDS!! Back with a vengeance

    E5fYW4p.jpgaipNUGH.jpg

    Hi guys im back ive been in the world of crypto the past year.
    Its been a rather crazy ride to say the least.
    I see the team is doing some mining?
    I have been dealing with asics for over a year now and am more then happy to help.
    if you have any question I can at least point you in the right direction if not answer them directly.
    Im going to look more into just what we as a team are crunching with them shortly .
    I just wanted to stop in and say hi while i had a moment ...HI
    I also have extensive extensive experience getting 6 gpus to work under windows 7.
    Dual power supply layouts PCIE risers ect.
    when i left i stated i hoped to return with knowledge that would make me a better cruncher.
    and i feel i have defiantly learned allot while i was gone.
    Made some money lost some money I was running 16 GPUs at my peak.
    Now that ive started migrating over to asics to farm my coins
    Ill be migrating some gpus back over to the team.
    currently running 4 in one rig dedicated to the team.
    seems to be doing nicely the rig was set up for 6 but running
    6 gpus off the same board is no little task....
    ive pulled 2 from it so i could eliminate one psu
    . any help i can offer ANYONE to save you some headaches please don't hesitate


    this is a pic of my very first farm before i learned A LOT of hard lessons
    Blew up A LOT of equipment
    Started a few small fires
    Ill get some pics of the big Riggs shortly

    Super glad to be back

    Hi NerdLifeAMD,

    I bought my Asus FM2A85-V Pro mobo from an ex-miner (it was beginning to cost him money to run it with 3 GPUs).
    Prices of electricity over here are so high that even older generation ASICs get dumped (everything below 5 Giga Hash USB sticks; 300 Watt S1 Ant miners; Butterfly Labs Jalapeno's: you name it).

    Butterfly Labs hmmmm i have very mixed feelings about them.

    I bought a 10Gh blade which came with
    NO Instructions .
    NO Pigtails.
    NO Pinout
    NO Cooling

    It took me three days to get it up and running

    1 moth later when bitcoin hit 1000 usd
    I sold it for just under twice what i paid for it

    As far as gpu mining with xll and x 13 power consumption is around 60 % less
    and hash rates are 300 Percent higher . even more if your savy
    put it this way regular script mining I could tweek my config to hit
    330khz 72 C and on x11 i can hit 1.4 MH at 68 C
    soo more like 450% hash rate

    as far as asics you guys and gals need to shop around if you are still using power hungry miners
    for Bit-coin or regular script mining

    please look into https://zeusminer.com/ before you buy any asics for script
    if you read the stats there smaller miners pull less power then a laptop
    and by smaller I mean a miner to replace 2-4 gpus depending on what cards you have
    is under 200 bucks usd and takes as much power as a laptop
    there lager miner 20MH use 1 standard computer power supply
    regular firmware updates and expansion boards
    they are really on top of things and faster and cheaper then gridseed



    but anyway enough of that for now
    I DO HAVE A QUESTION

    I have gotten good at bending my gpus to my will to get as much from them as i can see pic

    That is one of my config files for mining I wrote it myself I know what every line of code is for

    I DID make a config file when i downloaded boinc to get it to use all my cards
    It only wanted to use the one at first

    Are there any setting i can manipulate in bonic
    to adjust my GPU, CPU, FAN SPEEDS, SHADERS, ECT I know these cards run way faster then
    Boinc Is running them
    They are reference cards they are dramatically Underclocked
    I know I could use CCC but shmmmmm
    rather not install it if i dont have to sometimes it wont play nice with all the gpus

    farther more if tweaking does exist

    is there a way for me to get any real info from a benchmark after i make changes ????

    thanks in advance later

    one more thing im off tomorrow i have 4 6870s that have broken fans im going to try and put some new ones on them
    all Frankenstein hopefully have them crunching for the team in 36hrs

    One other thought ...... asics the smaller ones 5mh and lower typically run 12 volt ac adapters its not hard to generate 12 volts on the cheap
    if you are really into it .. newer small asics have be tempered for overclocking which we do
    point im trying to make is they are fine on dirty power from a solar cell and a battery
    sice they regulate amperage internally

    The HD 6xxx series seems to benefit from GPU_MAX_HEAP_SIZE=100.
    do you the the following in your start up script?

    export DISPLAY=:0
    export GPU_USE_SYNC_OBJECTS=1
    export GPU_MAX_ALLOC_PERCENT=100
    export GPU_MAX_HEAP_SIZE=100

    You can also use water cooling for the HD 6870s, might be more efficient and less loud.

    AFAIK there are no settings for you GPU in BOINC, but -to make better use of the GPU- you can try to run more than one WU (two or even three) at a time on the higher end GPUs,
    specifying that in the app_config.xml for the application (to be found/made in that application's directory).

    Different settings per project, but in general
    <app_config>
    [<app>
    <name>uppercase</name>
    <max_concurrent>1</max_concurrent>
    [<fraction_done_exact/>]
    <gpu_versions>
    <gpu_usage>.5</gpu_usage>
    <cpu_usage>.4</cpu_usage>
    </gpu_versions>
    </app>]
    ...
    [<app_version>
    <app_name>uppercase</app_name>
    [<plan_class>mt</plan_class>]
    [<avg_ncpus>x</avg_ncpus>]
    [<ngpus>x</ngpus>]
    [<cmdline>--nthreads 7</cmdline>]
    </app_version>]
    ...
    </app_config>

    BOINC client needs to higher than 7.0.40

    Im going to dig around myself but
    do you know if there is a good explanation of all those switches
    Mainly asking because i want to know what is a system wide setting and
    where each gpu has to be configured

    as far as water cooling the blocks probably cost more then the cards at this point
    when i dumped my cards i saw some as low as 50 USD ( Not ATI BRANDED )
    MSI Saphire XFX ect . These particular cards are extremely stable
    heat has not been an issue with bonic anyway
    sitting at 20% fan speed 73 C
    at 100% the fans are 4500 rpm squirrel style cooler
    they are also in there own room so that helps

    i have found that at 78 C all of the 6870 and 6850 i played with
    ran into a positive feedback with the heat that simply was unrecoverable
    without a cold restart
    the whole omes resistants law
    5 cards hit the target temp
    if they have to they will spin the fans 100%
    ive seen them hit just over 4500
    they in turn pull more amps
    heating the power supply then heating the room
    before you know it it sounds like a jet plane and the room is 85 F even with it own ac
    what i finally had to do was build a shroud for a gpu rack
    And pull the heat directly off the cards and suck it directly outside
