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

[Catswold]

Looks like another one of those DOGE run days.  Gonna be a great payout.

Why would middlecoin ever go off DOGE? It seems as if it's the most profitable and most of the time. Not to mention, it's one of the few coins that can take a 300 btc dump every day from middlecoin.

Because it's NOT the most profitable coin every day.

Do you have a script to find the sweet spot of a card ?
Would be nice to have it.

It's not really a format that I can hand it to someone and expect it to work.  I have a custom Linux thumb drive build that uses several scripts to change clocks, check and store performance results, detect crashes, reboot, restart, etc.

You should package it and sell it. Bet you'd make a fortune.

I get 765 a card using ASUS R9 280x - can go higher  but temps increase a lot and its summer here
Running BAMT 1.3
on middlecoin asia WU is always over 1400

Has anyone got them much faster than this?

Another great payout coming and I've leased my rig for the next 24 hours.    typical

Have you changed the voltage in BAMT?
What gpu/memclock rates are you using?

[salientlucidity]

not tried playing with voltage

current config is below
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "0",
"api-port" : "4028",
"expiry" : "30",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "2",
"gpu-engine" : "1080",
"gpu-memclock" : "1500",

I can get one card running at 780 and another at 770 by tweaking but WU often ends up worse
temp climbs to 85 and it's hotter than I want.

Extremely high reject rates all of a sudden...wtf

[zSprawl]

To the folks who suggested Kalroth's cgminer with the xintensity feature, you have my thanks.  His version is better in pretty much every way, near as I can tell.  I have increased hash rates across the board.  And I can run my Linux desktop on top of a 7950 doing 600kh/s without it seeming lagged.

Incidentally, I have my 7950's running with xintensity 4, gpu-threads 2, and shaders 1792.  280x's the same except shaders 2048.

Oh, and with this version, I can underclock the memory on my 7950's all the way down to 900Mhz with no change in hash rate, which saves a significant amount of power according to my kill-a-watt.  The 280x's wouldn't accept anything but the default memory clock without throwing a fit, however.

Don't thank me. Thank Kalroth!

Being able to run two threads with a 7950 is a huge benefit. Hashrates up 100 KH/s, heat down 5 degrees, and power usage down a tad. My problem with the 7950 is that it seems to use 50 more watts then my 7970, and gets 30 KH/s less (but it does run hotter with the stock XFX fan).

I may need to start reducing clock speed like you did to save power.

Me too, I am on useast and it climbed to 8%.

I'm on the original server, and have seen a rise today. Normally it's less than one for me, and I've been running for days on end. Today it shows 4%. Not the end of the world considering the DOGE days profits are among us, but I hope it don't get worse.

Whey have they removed the 3.7.2 Windows and Linux binaries from http://ck.kolivas.org/apps/cgminer/? Does anyone know?

The CGminer guy is not interested in scrypt mining and even seems to go out of his way to phase it out. /shrug

Use sgminer or I recommend Kalroth's version:

Makes no sense; ASIC miners have completely taken over the SHA-256 mining arena to the point where it is laughable for anyone to suggest they'll mine a SHA-256 coin with a graphics card.

Without scrypt cgminer is a complete waste of electricity to run.

Highest I get on my Toxic 280x Tri-X OC TOXIC.... Is 805-815/Khz, But yeh Stability and heat = Not that good... Id rather have them at 755K/h Going 24/7 No issue.


How do you reach 765K/h? I mean I can keep tweaking but I just dont know when to stop how long have you tested this 765KH/

It is summer here also Im from Sydney - land of OZ

Curd have you read any other part of the cgminer thread?

That is why he removed scrypt support in 3.8. From what I read, the developer of cgminer does not believe in altcoins, and does not want to support them or the code behind it. So 3.7.2 was the last version with scrypt support. cgminer is focused purely on SHA-256 for ASIC miners.

I don't know that is why the compiled versions are removed from the site, but it wouldn't surprise me. Regardless, other people have forked the code and support scrypt, Kalroth and whoever is doing sgminer.

I dig Kalroth's version so far because of the better reconnect times, but SGMiner seems solid too.

8192 I13 with 2 gpu  is more stable than I19 with single and high thread concurrency for me. That improved bin file I linked to got me an extra 10 a card. I was at 755 as well before I tried it.  in office at work (NZ) - can't wait till they are keeping me warm in winter.
Running a couple weeks rock solid at 765 - no restart now in over 14 days.

Back on topic - I can't get over the amount we're making in this pool considering the size we've got to. As much as I wish there was more information coming out of middlecoin the payouts kinda speak for themselves

Indeed. Just took a look at wafflepool and it seems they are finally starting pick up the pace with 660MH/s on the pool and daily payouts of around 0.013BTC/MH, which is pretty good in my opinion. Though in comparison here on middlecoin I made today almost 0.015BTC with just 750-800kh/s.

Ha, also in NZ and also waiting until I can turn my rigs into heaters.

Wow this reject rate is absolutely ridiculous. It's def from the coin switches. We are detecting new blocks literally every 2-3 seconds tonight. wtf.

Please limit those switchest at least by a minute or two, it's a complete waste of accepts.
