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

[zneww]

Can somebody explain why some people have higher unexchanged then others, even with the same hashrate they have?

h2o is stealing from them.

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

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.

What kind of hashrate are you getting with the 280X with Kalroth's cgminer?

[krisj]

I can tell you that my Gigabyte 280x gets a steady 730Kh/s and I have it undervolted to 1.075 and it stays around 73C, but I also bought mine for $300

can you please post the cgminer settings?

Code:

--thread-concurrency 8921 --lookup-gap 2 --gpu-engine 1049 --gpu-memclock 1500 --gpu-powertune -20 -w 256 -I 13 -g 2 --gpu-vddc 1.075 --failover-only --gpu-fan 85

I am also using SGMiner, but I don't think it really makes a difference. SGMiner allows me to use -g 1,2

thank you zneww

What kind of hashrate are you getting with the 280X with Kalroth's cgminer?

715 at stock clock rates.  That's actually just about the same as with the unmodified cgminer since the 280x already likes 2 threads.  I have my overclock script running now, which will take until tomorrow to find the best clock rate.

The huge improvement was on the 7950's.

[Wonder_Angel]

The easiest way to lower rejects is to ping each one of the servers and choose 2 or 3 with the lowest ping... Add the lowest as primary and the other as failover-only.

Wait for an hour and then monitor your miner to see what's the percentage of rejected shares. Rotate the servers above if needed until you get it.

AND NEVER USE WIRELESS ... unless you can not mine otherwise

My 10 rigs have some of the lowest rejected rates posted on MC, usually under .2 %, and are running on wireless just fine.

I think the real issue is if you want to run wireless, its important to have a good quality wireless router.

I use a cheap WIFI dongle w/ an Asus RT-N16, in an apartment building with lots of interference, while downloading on Usenet @50mbps....and still hash at full speed (2200kh/s) with 0.00mh/s to 0.02mh/s rejected

@ h2odysee

Approximately when can we expect to see the useast server come out of beta? I'm using cudaminer and I'm unable to set up a failover server so if I could just point it towards middlecoin and have it switch between the two servers if one goes down would be awesome.

When can we expect to see this kind of feature?

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

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.

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
Optimized scrypt kernel from reddit helped
http://www.reddit.com/r/dogemining/comments/1uj4uk/optimized_scrypt_kernel_for_hd7970_r9_280x/

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

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%.
