New Miner Needing Help with HD7870 settings on NSGminer?

wrapper

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.

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?

greenuser

@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

greenuser

@wrapper, I got loads of CPU and Ram free

You are running windows?

greenuser

@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The guide for virtual box is a out of date and needs some further fixes from the transfer to the ne NodeBB forum.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)

wrapper

@Wellenreiter That was not the point of the analysis, we measured the time from each computer to a common site/point in Germany!

The data still told us if the person being supported had a worse connection than me, by linking to the same site. I tried pinging to the actual site first but that seemed blocked.

My rig failed-over to https://give-me-coins.com at just past midnight last night. I’m looking at it hashing now and have received 30ftc in 12 hours, is that good?
651 KH/s for 12 hours with 0% invalid shares.

It should have failed back again when http://p2pool.neoscrypt.de:19327/static/ came good.
Maybe the software takes the better pool for my settings. p2pool.neoscrypt.de is still my prioraty pool.

Your earning seemed OK for the time mining, you loose stratum changing pools though.

I had trouble with failing back (on one of my miners), it may be a bug / incompatibility to the particular driver.

… which is why I went to my own local p2pool, which is a buffer to connection issues. Local p2pool has been rock stable, no failovers since.
