[ANN] profit switching auto-exchanging pool - www.middlecoin.com

[atp1916]

[snip]

About queue, expiry, scantime: Keep them default.  I don't touch them and i have 0 issues with connectivity.

About worksize: Keep this @ 256.  It has nothing to do with the pool difficulty, but rather GPU work unit.  HD 7xxxx series cards appear optimized for -w 256.

About gpu threads: 7950s love gpu thread @ 1, with a high(er) Thread Concurrency number.   7950s appear optimized to run with 1 gpu thread and a high concurrency.  Ensure that your thread_concurrency number is a multiple of 2 (2^n). 

About vector: Unused, good for delete as you already have.


Your primary GPU related settings are: intensity, thread_concurrency, worksize, and gpu_threads.  When you're using the config file format, tune those and leave everything else at default (unless a pressing need presents itself.)

I would also recommend setting your GPU fan to a constant 80-90%.

Hmm, just doing math, with Bitcoin at $440/coin (which it really isnt at yet) and based on last nights payouts (.0092 .0077). My 6 7950s (in 2 rigs, 3 7950s per rig) are basically breaking even with power costs. (.105/kWh).

Crappy.  So if bitcoin continues this crazy rise then it is worth it, but now I am speculating my power costs plus my rigs have not yet paid for themselves.   Time to unplug?

Don't get discouraged yet.  I thought the same when I first started.  I seen low payouts for the first 2 days then I realized that some of the coins that get mined takes a few days to mature.  I have 2 7970's, 1 7950, and 1 5870 that mine total at around 2.2 MH/s.  my paypouts average now between lowest .013 to a high of .038.  A lot better than I was doing just mining litecoins myself.

Thanks for the insight.

For now, I'm seeing low 70's for temps using the autofan to throttle the RPMs,  which should help to preserve the fan life.  I also have, left over from another project, three 5" Pabst 120 V.A.C. computer-style ball bearing fans running through a rheostat, positioned above the cards, feeding them ambient air which helps a lot to keep temps down.  Once I ramp up the intensity,  I figure that the gpu fans will ramp up anyway, but I'll see if I have to increase the max rpms or not at that point.

I got the thread concurrency number in my above config by following some instructions that I found on the internet and checking the .bin file name,  and also off of the GPU comparison wiki,  and used the one listed for my card.  The number in my above config seems to be the max that I can use,  or else the rig will crash.

I will leave the worksize and gpu thread numbers as they are,  also. Thanks for the clarification.

The default queue,  expiry,  and scan-time numbers were 1, 120,  and 60 respectively.  If I leave those at default,  won't it be bad to have work sitting in a queue,  and also bad to have my cards checking shares for a long time that might become stale as they are being checked?  Or is it bad to check them too quickly for some reason?   I'm still trying to figure a lot of this stuff out so bear with me. 

Another question: If I am looking at the Middlecoin work graph for my rig,  I see some instances where the red balance line flatlines.  Is this an instance where the server is down,  or is this where my cards are doing work and not putting out valuable shares?  I compared my chart against other peoples,  and I can find identical flatlines,  just trying to figure out what those mean.  I'm pretty sure that someone explained this somewhere in the thread before,  but a search didn't bring it up.

The red line represents your balance. It goes up when my bot makes a trade and you get credited. So if it's flatlined, that just means that no trades have gone through for a while for you. You will still be accumulating immature and unexchanged balances though.

An important number is the total of your immature, unexchanged, balance, and paid out columns. Andrew12 made a nice graph showing that at http://middlecoin.andrew12.net/

If the pool goes down, your miner will be disconnected.

So some unsolicited feedback about the pool.

I've used other multi pools, did my own profitability switching via CGWatcher, and just speculation mining of coins and I have to say I've had a steadier and higher income using middlecoin than any other previous method.  The only complaint I can really make about the pool is the slightly higher pool fee over others but it's like complaining about the color of a Maserati.

Just wanted to say thank you h2odysee for this great service. Well done.

Your service makes it super easy and convenient for us newbie miners to get started.

Anyone know the current BTC per MH?

Thinking about firing up my 1MH rig this weekend out of being out of commission for a bit.

Hey I just started mining with BFGMiner and everything looks like it's running great, the connections are there and it's running at 12mh/s but I'm not seeing any accepted work from the server even after 3+ hours? I went to the main site and did a quick ctrl+f with my wallet address I used for the username but couldn't find it represented anywhere.

Am I just being paranoid and don't know enough about this yet to understand that my set up is in fact working smooth or is there a connection issue somewhere that I'm not aware of? When I was pool mining with the bitminter client I would regularly get accepted work even after 10 minutes.

It shows that it's communicating well with the server and working on blocks, I just don't understand. It seems like every time I think I have a smooth set up with this stuff I wake up to realize it was only working on the outside.

Any help or advice would be much appreciated.

Is bitminter for mining bitcoin only? Or do they do litecoin as well?

If you're not aware, my pool is scrypt only, and you need to configure BFGMiner to mine scrypt, not SHA256.

No wonder!! Thank you! I wasn't aware at all that I needed to configure BFGMiner to mine scrypt.

EDIT: So, to get it running in scrypt mode I just have to put --scrypt in the .bat file I use to open the program. It opens up in CMD and doesn't have the nice interface but it seems to work!

MC has turned me into a very lazy miner.

Another question: If I am looking at the Middlecoin work graph for my rig,  I see some instances where the red balance line flatlines.  Is this an instance where the server is down,  or is this where my cards are doing work and not putting out valuable shares?  I compared my chart against other peoples,  and I can find identical flatlines,  just trying to figure out what those mean.  I'm pretty sure that someone explained this somewhere in the thread before,  but a search didn't bring it up.

Ok,  thanks for the info.   Do you or does anyone have any insight as to what is the best way for me to set the queue,  expiry,  and scan-time settings?  Some say to leave them at default,  some say to lower them from default,  and then I read a post somewhere that scrypt mining is not affected by them at all,  so I really have no logical guide as to what to do with them.  Right now I'm going with q=0, e=2, st=2.  

In other news,  I spent some time today and fished some 12/3 down to my breaker box,  slapped in a dedicated 20A relay,  and boxed in a nema 5-20r in my wall,  so I am almost ready to start ramping up my intensity to see how much work I can get out of it.

I'm getting about half the btc per day that I usually get. I wonder what is going on.

I'm getting about half the btc per day that I usually get. I wonder what is going on.

My guesses would be either A: Its Saturday or B: Someone is expecting a downward correction of BTC. Fortunately or unfortunately the former is obviously a more likely scenario than the latter. Meaning (IMO) there will probably not be a significant downward BTC "correction" near term.  In the case I'm wrong there will be nice gains soon, if not keep hashing for middlecoin and get what you can while you can. ATM I've chosen to Load Balance between MC and another LTC pool FWIW.


There are also major US (BTC) hearings/ AKA herrings  scheduled for next week? Which BTW probably will not have much effect (on BTC valuations) one way or another. In other words "the ship is sailing, not under 1 flag but many" . Basically the US has as much to lose as other countries have to gain by this new tech.

Welcome the ultimate Paradox as the supposed "representatives" of a free market society attempt to stifle a Paradigm shift in currency technology. Worry not, the oft despised "old" money masters will soon join the new money masters in correcting their Orwellian henchman's views on this new asset class. I love the smell of irony in the morning.

Wow, I was away from this thread for a long time, now there are over 100 pages! 

What ever happened with the whole difficultly level? Was it ever changed or were any experiments made regarding lower values?

Yeah here's a summary:

People asked, H2O said no, so then people made Hashco.ws which supports VARDIFF.

It's a tear jerker.  Gets me every time.

The question is, did it make a difference to their earnings?

[jedimstr]

It did to mine, but YMMV. I ran both in parallel for a few weeks and now use the cows as primary pool and Middlecoin as failover backup.  All really depends on a lot of variables like the hash power you have to wield and the different philosophies of both pools, but this is just how I ended up.

I've 3MH - does that compare?
