New Miner Needing Help with HD7870 settings on NSGminer?

  • | Tip greenuser

    Hi, i am trying to get a rig mining FTC.
    Up until recently it mined ethereum with this setup.

    I use windows 7 -64bit, HP ProLiant DL380 G5 Server with four Sapphire AMD Radeon HD 7870 Dual-X 2GB GDDR5 (11199-16-20G) GPU cards and AMD Catalyst 15.12 drivers.

    I have an old account at Give-me-Coin from BTC mining so i got the URL from them and set up a worker and added a LTC address.
    i got nsgminer from https://github.com/ghostlander/nsgminer/releases
    and unziped it.
    I put a bat file in the same folder like this,

    nsgminer --neoscrypt -g 1 -w 128 -I 16 --gpu-engine 1000 --gpu-memclock 1500 -o stratum+tcp://ftc-neo.give-me-coins.com:3336 -o greenuser.1:12345

    ftc-neo.give-me-coins.com = url
    3336 = port
    greenuser.1 = workername
    12345 = password

    Now waiting on a system restore!

    will try with lower Intensity.

    Any ideas welcome i am still waiding through http://forum.feathercoin.com/topic/8235/nsgminer-v0-9-2-the-fastest-feathercoin-neoscrypt-gpu-miner

    Thanks in advance.

    PS: if eth continues to go the way it is going, I can see more coming here.
    FTC was top of the chart yesterday on https://www.whattomine.com/
    So a good fool proof How-to-mine would be cool.

    Warm wishes

    nsgminer --neoscrypt - -I 13 -o http://p2pool.neoscrypt.de:19327 -O FTC address

    Try this.

    NSGminer sets it’self up fine, you can try adjusting once your in.

    We can see if its conecting on http://p2pool.neoscrypt.de:19327/static

    Re :

    Unfortunately, technology and software changes with ASICS and such. NSGminer has recently been updated and simplified.

    The correct place to have a good set-up guide is on Github with the software documentation, if possible… 🙂

    @wrapper Thank you
    Well im hashing at somthing…

    All the GPUs are same make and model but differ in Kh/s 😕
    Power load “at the wall” is as i expected. However,i was hoping for ~800KH/s for four HD7870s
    Can i map my cards with commands like…
    setx GPU_FORCE_64BIT_PTR 0
    setx GPU_MAX_HEAP_SIZE 100
    Also, how do i check my my stats at the pool? http://p2pool.neoscrypt.de:19327/static is network stats.

    If you go to the bottom of the page, click Additional graphs, and scroll down till you see you Address.

    The p2pool is a distributed pool where you mine for shares, you will see the proportion of the 80 FTC block fee you will share with other miners on “Global” p2pool. p2pool.neoscrypt.de is just on a server, there are lots of other instances, not just one server.

    This means you can failover to another p2pool server (with same version) and keep your shares and any stratum you’ve built up.

    Re : set GPU_MAX_ALLOC_PERCENT=100 etc

    You can try them but I don’t think they are needed and the crashed my PC when I tried them, so be prepared to reboot.

    Re: P2Pool additional graphs.

    You can now see you “earnings going up” that is the current percentage of the next p2pool payout, it is the amount you would get if p2pool found the block now.

    The amount you get will go up and down depending on the Global pool rate. When the next block is found will also depend on the pool rate, If the rate is high you will get more blocks but lower percentage and vica verca.

    As for the card settings if you press [G] the [ I ] on NSGminer you cant start gradually increasing the Intensity, as you first step into mining optimization. You may get back to I 16 if the xSet commands caused the blue screen!

    Note : I’ve edited the title so any one who has a HD7870 might have some better settings… I have a R9 290.

  • Moderators | Tip wrapper

    P2Pool just got a block 5 minutes ago, so you got a 6 FTC share, should be in your wallet now

    You can see who else was on the p2pool group on blockchain explorer :

    thanks wrapper, your cool. thanks for changing thread title.
    I’m just going to let it run for a while, as I have loads of washing to do and get dry.
    Mining is ideal for that.

    I had to restore my machine to the last restore point so when i got it back, my newley installed wallet was gone. So downloaded and ran the wallet again and it now has to reindex (2 yeas & 25 weeks behind).

    The address is the same as before so it must have picked up the keystore file ok.
    So i got a wait to see my FTC. 😀

    So i get a payout when we find a block?

    I may bring you luck

    Warm wishes

    Re : Mining result, you have a reasonable rig at the moment so should see regular payouts for a while, even if Global hash rates double. Difficulty is now averaging 15, whereas it has been steady at about 7 for months, so you missed out there!

    No problem,

    My NSGminer stop working ~16:00h, restarted, now ok, i might disable “Areo” theme in Windows.

    The blip before midday was a windows update i had been putting off.

    Also, last night i was mining on the node and saw high stale hashrate, i closed NSGminer, restarted then all ok. Any ideas?

    I need to keep an eye on this rig, eth mining was very stable for me.

    Also; I will be updating my address in a day or so when my laptop wallet has synched.

    Do we have a place on this forum where node users can all communicate?

    Warm wishes

    @wrapper It isn’t possible to increase intensity past the initial. It may be reduced and increased back to the initial. Memory allocation depends on intensity. It’s performed only once on start-up.

  • Moderators | Tip wrapper

    Yes, she started it on I 16 - it crashed and blue screened te PC, see the “new members” part of post ,

    I explained that NSGminer does a lot of auto settings…

  • | Tip greenuser

    yes, HD7870 max intensity is 13,
    Getting stability takes time. It will come!

    @wrapper, i think the bit i wrote about it going blue screen was on the Newbie thread as you said. look…

  • | Tip greenuser

    Any ideas why NSGminer mines well for hours… but just decides to stop working and shuts down? i run the bat and its fine again…, for a while anyhow! I used to have an Antminer U3 like this, hmmm… doesn’t take long to get fed up with resetting. 😩

  • Regular Member | Tip ghostlander

    @greenuser Look at the system log. It could be hardware related or pool issues.

  • | Tip greenuser

    @ghostlander , Application error! according to event viewer. A driver failed and then recovered just before. I’m having to reset every 2 hours. This is doing my head in, just haven’t got the time for all this, too many cloths to dry. I might go back to mining ethereum as its heat from the GPUs i’m after, the crypto coin is just a by-product, and I just don’t have the time to spend tweeking.😠

  • Regular Member | Tip ghostlander

    @greenuser If there was a driver recovery, reduce GPU and/or memory clocks (–gpu-engine, --gpu-memclock).

    Ha, I remember seeing you on the ethereum forums. I posted a pic of our aging but useful DL380’s in our data center. 😁 I do remember you, the guy who had the miraculously left behind Tesla K80, and another with a near-useless M2090 (that I helped anyway).

    Man, that must be close with max power draw; 2x4-core xeons + 4 7870’s, 1600Wpsu’s if I recall…
