New Miner Needing Help with HD7870 settings on NSGminer?
-
yes for sure. Once a basic bat file has been made and exicuted and… you have created a conf file by hitting [S]ettings then [W]rite while running, you no longer need the bat file. You can get rid of it.
You can then just run the nsgminer.exe to start mining and arguments will be read from the conf. This way i get to see all the defaults and make changes as needed.
Tommorrow i will edit the “nsgminer.conf” file with the GPU core 1000MHz and GPU memory 1500MHz arguments and post results.
Thank you for the arguments values :pray:
-
I will edit the conf like this

Ok this rig has run fine mining Ethereum for the last 4 days
Today i tried to mine ftci tryed these bat files commands
nsgminer --neoscrypt -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap
Then:
nsgminer --neoscrypt -I 12 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap
Then:
nsgminer --neoscrypt –-gpu-engine 1000 --gpu-memclock 1500 -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap
Then:
nsgminer --neoscrypt –-gpu-engine 1000 --gpu-memclock 1500 -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap
The command window opend on each time and i saw some writing but it went blue screen with white vertical stripes before i could read anything. Had to reboot to get rid of the stripes
So then i tried sgminer 5 with
sgminer -o http://p2pool.neoscrypt.de:19327 -O 6gTcFMDZeJRL4tgJbnHQDjXZe8Gm7kKaT8
and got the same blue screen with white vertical stripes, again needed to boot to get out.
Currently mining Ethereum again.

Ok its working!
I reinstalled all GPU drivers and noted clock and core values in GPU-Z while mining Ethereum
Core 1000Mhz
Clock 1200Mhznsgminer --neoscrypt –-gpu-engine 1000 --gpu-memclock 1200 -I 13 -o http://p2pool.neoscrypt.de:19327 -O 6wTKzQovBDnMrhxtcR44KyLz3xWAPx15Ap

Are you using this address: 6gTcFMDZeJRL4tgJbnHQDjXZe8Gm7kKaT8?
After about 3 hours of mining our stale rate went up and is at about 84% at the moment.
Looks like you set your GPU parameters a bit to aggressive -
@greenuser Did you try nsgminer with no setting? I’d be interested to see what Engine settings NSGminer sets on it’s own. It poles the GPU for it what it thinks its settings are.
Also, I found one of my cards would not run stable over Engine 980 it might be worth trying 990. You can check by optimizing the engine speed to reduce the number of rejects.
Sometimes a lower engine can give the highest hash, as its a complex relation between memory and speed which is different for every hashing algorithm. Also, the highest hash is not necessary the most energy efficient.
-
I get the same results with no settings, when i reduce values, hashpower goes down.
But now that i am hashing, why do i get 50%+ stale hashrate?
shutting down as i am using power but not making coin. -

Others here seem to have Stale hashrate 20%+ too. 6f1q2U6TuR8FijX96na9dHDko4HYAu3XPr

}So i turned up Mem clock to 1300 and turned down Core clock to 970.
Mem Clock shows correct values in GPU-Z but Core clock (gpu-engine) still reads 1000Mhz although set at 970Mhz, not sure why.
Ints set down at 11I will watch for Stale Shares

shutting down as i am using power but not making coin.The fact that other miners are suffering, means it is with the server or communications to it. There is trouble with connections the further you are away, for instance.
Not having a good pool connection : it’s one good thing about running a local p2pool node, it acts as a buffer, collecting your shares then passing them round the network.
Also, it would be interesting to save a ping in a 5 min chron script and do a chart of connection variability from the output.
-
So i need to find a closer pool to me here in Cornwall UK?
-
@greenuser stales can be due to connections
I say you need to run a p2pool node like me, it’s pretty easy and low power. ie there are few in UK on about cornwall
How much are the cpus doing now on your miner?
-
@wrapper Low on hard drive space, how big are the files?
Relatively small, it clears over a day as stratum is reached and block go by. I think it is python, I’ll see if I can see
-
@wrapper, I got loads of CPU and Ram free
-
You are running windows?
-
@wrapper yep
-
Looks like a windows build is possible. Or try Ubuntu Bash on windows and compile it in there.
It isn’t a simple download / release yet as far as I can see.
I’m sure Wellenreiter could do one, when he can get time, we’re a bit over run building and test a couple of new releases.
There are other members about that have helped with windows builds, who might see the thread and help.

The guide for virtual box is a out of date and needs some further fixes from the transfer to the ne NodeBB forum. So, I’ve done an emergency fix, but that guide needs replacing updating now…

I’d be intersted to see your ping, I’ll do it from here for comparison : ping neoscrypt.de

Well neoscrypt.de is not the p2pool host, probably not even in the same data center, as I can see from the IP Address returned.
The p2pool node is p2pool.neoscrypt.de (ip 46.4.0.101)
