New Miner Needing Help with HD7870 settings on NSGminer?
-
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. :weary:
-
@greenuser Look at the system log. It could be hardware related or pool issues.
-
@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.:angry:
-
@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. :grin: 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…

Your memory is not that good though. I was one of the few female miners on the forum.
Don’t worry, demmographics in crypto and peoples mind set…, it’s the 21st century and we are still under represented in many areas… and yes, i have enough switch mode PSUs to start a V8 :smile:
So you left the Banking Establishment’s crypto foot-in-the door, coin to mine ftc? :smirk:@ghostlander thank you, things have settled now. One card had differing results from the other three in NSGminer. I dumped a .conf file while running and went in to have a look.
All values looked the same for each card (i did however trim my fan speeds to get all the cards at ~ the same temp) so i then looked at my AMD settings and one card was slightly overclocked in frequency for some reason. Driver seems ok now.
I note your recommendations and will try if i have further difficulties, can i just add them to the list in the .conf file of NSGminer?All running sweet now fingers X

Of course I remember you’re a lady, sheesh! :blush: My 50-ish brain hasn’t melted yet, (though my kids are always trying to turn up the heat). And I think you already posted a pic over there, it was sitting on a table in your dining room or near your kitchen if I recall…
I’ve mined FTC for a couple years on and off now with some others inbetween. ETH was a quick buck for me; got in in January and quit in April, bought my kids new PC’s with the proceeds without having invested anything in “mining equipment” (game boxes I’ve owned for years). I just love the blowhards over there who call themselves “professional miners” — a true deprecation of the p-word. :disappointed:
Too many people think fintech is actually going to use one of these public cryptos for something, causing its price to do a moonshot. :rolleyes: <— (we need this emoji!) Sure, some blockchain variant will get cred and “affirmation” if it’s used (only in their backroom transaction services, eliminating jobs of course), but crypto as a true form of payments are still a long, long way from critical mass public adoption. Especially when it takes a wallet hours to sync a few weeks worth of blocks (looking at you, bitcoin).
Oh well, nice chatting, time to put the boys to bed… :family:

@bluebox I am convinced that ethereum is the banking establishments secret weapon to try dominate crypto. They want to discredit public blockchains in favour of private banking blockchains. It will all come out soon that eth has been adopted by the same banks that crashed the economy.
People will lose their shirt in eth, already being asked to double down the dao and the word “Ponzi” was in my head from day one. Anyhow, I love a good Ponzi, early adopters make the coin. You just need to remember to get out when asked to double down. I did ok though, but it is a changing world, and there is a need to stay ahead of the curve.Feathercoin attracted me because of the ASIC resistant algo, slightly better encryption and the attitude of the dev team and community. I watched the vid on the feathercoin web page and compared it to the vids I remember from the ethereum and the slockit dev teams. Go look for yourself. It looks more “bottom up” here (ftc) and more “top down” over there (eth). I also think feathercoin is undervalued in the markets and could be a good hedge against Brexit fuelled GBP (£) losses. It need better suport from the exchanges though.
Anyhow, back to work,
NSGminer stopped in the night last night. The application did not crash. I looked this morning and the column after the fan speed figures had displayed the word “WAIT”, I restarted and it is hashing now. I may do ghostlander’s idea of reducing GPU and/or memory clocks (–gpu-engine, --gpu-memclock) in .conf… If I get time today that is… We are getting drunk ATM, celebrating the first British Independence Day -

A .bat file like this will not run
nsgminer --neoscrypt --gpu-engine --gpu-memclock -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap

OK i am mining on ethereum nanopool at the moment.
It will mine for about 2 min on feathercoin and then it tells me to WAIT!PLEASE SOMEONE HELP ME GET FEATHERCOIN WORKING.

try this
nsgminer --neoscrypt -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap -
@aciddude yes, that is the line i used to get it running (and then I dumped the conf file as above) but it stops after a couple of hours. Can i edit the conf in any way to keep it running?
-
Have you tried different drivers or reinstalling your current ones? Have you tried with a fresh nsgminer and config? Have you checked GPU memory usage while mining? There are so many things is could be, you are going to have to try a bunch of stuff to find out whats going wrong. Welcome to being a miner!
I have seen so many crazy bugs over the last 3+ years of building and tearing rigs down, once you get beyond simple config issues I find it best to nuke it and rebuild from scratch.
-
@RIPPEDDRAGON Thank you, I will have a play tommorrow, I am looking at it hash away now mining ethereum. It works perfect for days, totaly unattended.
AMD Catalyst 15.12 drivers are the best for mining eth, Later drivers yeald lower hasrates. I will try a driver update tommorrow while nursing my hangover. :smirk:These are hard faults to find. It will hash away all night on feathercoin and then just stop and display “wait”. It has mined 127 ftc over the last two days but it’s no good to me if i have to reset it every few hours.
As i say, i used to have an Antminer U3 like this. It would work for days and then just go “ZOMBIE”. I guess “WAIT” in NSGminer is the same as “ZOMBIE” cgminer!
I was so glad to see the back of those ASICs -
@greenuser --gpu-engine and --gpu-memclock require arguments. For example, --gpu-engine 1000 --gpu-memclock 1500 set the GPU core to 1000MHz and GPU memory to 1500MHz (6000MHz effective).
Don’t set --gpu-vddc to zero. It’s no good.
WAIT happens when the miner waits for work supplied by the pool. SICK, DEAD and HW errors are signs of GPU issues.
-
@ghostlander Thanks, will try tommorow and post results. What value should i set --gpu-vddc ? or should i remove that line from the conf
-
@greenuser You better remove it to keep the defaults.
-
@ghostlander i asume it is the default value. All i did was put this line in a bat file
nsgminer --neoscrypt - -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap
I then ran the bat file and then once running hit [S]ettings then [W]rite to make a config file.
The above post “My current nsgminer.conf file for 4 off HD7870 looks like this…”
is the un-edited conf. I just changed fan speeds to make all cards run at the same temp (cards in the middle of the rack run hotter than the outside ones)
The --gpu-vddc value is what is set as default. -
@greenuser -I 13 or --intensity 13 are both correct. Note the number of hyphens.
