I'm a bit disappointed by my S3's on P2Pool. After 1 day mining:

The top one got a lot of hardware errors so I just run it at stock, the bottom one overclocked quite well to 250...started off well on P2Pool, but reported hashrate is pretty bad on both. Note: the node is not close to me, but it shouldn't show this much difference - my old S1's did fine with it.

EDIT: anyone know what the discarded shows? Mine seems pretty high.

[IM]http://i.imgur.com/tCkQfJN.jpg[/img]

Your error rates look great, both well under 1%, have you tried another pool to see how they preform?

jonnybravo0311 seemed to get the best results running them at stock clocks....

Edit: Ant error rate calculator: http://www.coincadence.com/antminer-s1-hardware-error/

(was built for S1, but works the same for S3...)
So far, yes, I've seen the best results on stock clocks.  One thing I have noticed is that one of my S3's performance slowly degrades.  It hashes at 440GH/s for a while... then slows down to 430 and 420.  Rebooting it sometimes helped, but a lot of times on reboot, I'd notice one of the ASIC would show a status of "-" instead of "o".

So, this morning I completely stripped the thing.  When I pulled off the heatsinks, I saw thermal paste everywhere.  It was on the chips, on the PCB, on everything.  So, I cleaned it all up and re-applied to the chips.  Everything is put back together and it's up and hashing again.  Hopefully, it will stay consistent now.  We'll see Smiley.

I'm probably going to do the same to my other one as well.  Then, I'll retry over clocking them both.  Some people have reported amazing success.  For example, Goxed has his happily hashing away at 504GH/s (250 clock).  Now that would be nice!

One of them is actually running at stock, with the same degredation over time. When I started them, they were running at 440Gh/s and 504 Gh/s respectively, then over a day went down to 410 and 440. Now they seem stable at those rates. Haven't tried them on another pool, yet.

You should at least forward the p2pool port.  That'll get you more connections and make you more likely to win the share race.  Same for the Bitcoin port.  But technically you don't need to.

M
Ok, can you explain a little more the bold part?  Not sure I follow why letting other connections in helps.

I would have thought that the server running bitcoind would be just pulling down shares and feeding them to my miners, then putting them back up when solved to whatever peer it connected to get them from in the first place.

I think he means that there is a better chance that your p2pool shares do not get orphaned if more nodes are notified the moment you find your shares. It is a known fact that a p2pool node with poor connectivity to other p2pool nodes would end up having more orphaned shares, and you don't get credit for them. Forwarding your p2pool port means that you have total connectivity from both outgoing as well as incoming connections. If you don't port forward then you don't have incoming connections and have to rely solely on your outgoing connections to broadcast your shares.

@windpath: Here it is Payout address  1CpWdpMT3ygMUxJKrspF8ax4EDPmyTZ3m8

I can see the gaps in your payouts now, whats your average expected time to share?

Have you tried taking a look at BFGminers pool management console while you think this may be occurring (press P to access pool management in the console)?


Currently Expected time to share: 2.6 days. I would say the average is about 2 days. What should I look for when I press P? I really do not know what is going on.

Ahh ok, that makes enough sense, thank you.  That being the case, looks like I'm going to want to open inbound connections then.

If you are really concerned about it here is something I do.  I am not sure it helps but it makes sure my node is fully connected.  On my p2pool node I just leave maxconnections alone BUT I have a full node on my windows machine (to play games with) that I bump maxconnections up to 80.

I then addnode=10.1.1.5:8333 from my p2pool to my games machine.

I cannot say it really makes a difference because I have never really thought of a good way to test it, just the simple maths of 87*n (87 being the outside connections and n being the total connections of my pairs) makes me think that I should have a fairly decent "2 hop" reach.

Of course, it only matters when you are the person that finds the block, and in all my years of mining that has been 5 Wink

That's an interesting thought... adding your machine running the bitcoind.  I'm a bit confused, though.  Are you running the bitcoin daemon on both your games machine and your p2pool one, or are you using
Code:
--bitcoind-address ip.of.gaming.box
when you start up your p2pool node?

@kgb2mining, another option to consider is ensuring you have connections to nodes that are close to you.  There is a command that you can pass when you start your node:
Code:
--p2pool-node http://some.close.node:port
This forces your node to connect to this particular in addition to the ones it will randomly connect to on startup.  Remember, the orphan race completely depends on which share chain is longer and gets broadcast across the network first.  If you're broadcasting your own version of the chain to a node that's 500ms away, and I'm broadcasting my chain to that same node, but it's only 50ms from me, I win the race.

Sorry, that was not totaly clear was it?

Yes, bitcoind on both machines and edit the bitcoin.conf on both, adding;-

addnode=IP.OF.GAMES.MACHIENE

To the bitcoin.conf of the p2pool machine and;-

maxconnections=80

On my games machine.

In theory it may help in 2 ways;-

1. Less open connections on your p2pool. (saving resources)

3. When you find a block it is propagated quicker (less orphans of blockchain blocks YOU find).

It is all theory of coarse but it is an easy way to reduce the resource load on your p2pool server if you are worried about it.

You can also do a manual addnode to bluematts backbone network
Code:

> To peer with the public relay nodes, simply select the closest region
> out of us-west (West Coast US), us-east (East Coast US), eu (Western
> Europe), au (Australia), or jpy (Japan) and add
> public.REGION.relay.mattcorallo.com to your addnode list. Note that
> since all of the relay nodes will relay between each other, you gain no
> latency advantage by peering with more than the closest node to you (and
> currently all the regions map to one node, so there they're redundant
> anyway).
>
> For each relay node, you can connect to either port 8334 or 8335.
> Connecting on port 8334 will relay only blocks, and port 8335 will relay
> both blocks and transactions. The relay nodes will request any
> transactions which appear in your invs no matter which port you connect to.

Hi,

Looking to start a Razor coin p2pool, does anyone have the detail for the networks.py file?

Or point me in the right direction where to get it all?



Thanks

Razor has already P2pool up and running (according to coin OP).
Ask in proper thread. It is simple LTC clone https://bitcointalk.org/index.php?topic=644498.0

Anybody notice a drop in shares?Huh
With no changes in setup or machines....
My shares stopped late last night...
So today, I rebooted my computer and reset the system and started everything fresh even the bitcore....
Now running 4 hours at 4 TH and 0.0 shares...
Thats very unusual as I usually get about 2 an hour on average...
Just wondering if its only me?Huh

That's variance for you.  Now... that's some pretty crappy luck, but, it happens.  Sometimes when that happens to me, I give my miners a little pep talk.  Positive words of encouragement like, "I'm going to trade you in" and "Do you want to end up on eBay, too?".  Then, a lot of times if that doesn't do the trick, I'll threaten them with unplugging them and not plugging them back in or forcing them to work on the same block over and over until they get it right.  In extreme cases I'll reboot everything repeatedly, just so they know who is in control.

The share difficulty keeps increasing.  I saw it almost at 4m earlier today.  That's going to mean less shares, but theoretically more blocks.

There's a magic word I use frequently to get computers and electronic equipment in line.  It works wonders.  Just get close to the misbehaving gizmo, stare deep into its innards (or its case, if it's sealed), and quietly whisper, "Defenestration!"  It means to throw out of a window, preferably from a very tall building.

To be fair, it may not always work ... but it's certainly therapeutic for me!

I'm seeing basically the reverse.  My number of shares is about the same as it was before (maybe a 20% drop or so; that's normal for me), but my payout has dropped to 1/10th of what it was yesterday.  I'm puzzled at how huge a change that is in such a short period. I know variance can be a pain, but this is different.  It suggests a massive influx of hashing power to the network over the last day or two.

It's been quite solid the last couple of days, and you can see the pool has been growing all month:

My payouts has show a complete 50% drop during this time.
BUT - As many of the people on this forum have said.....
I see more blocks and I am getting the same payout if not actually a bit more $$$ in the long run....
Just hope that this holds true as we move forward......
My shares stared to return, not at 2 per hour but.... they are starting to come in again.
