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

[Biggen]

My unexchanged balance is basically the same as yesterday.  Maybe .01 less or so.

The red graph has more of an upward trajectory unlike yesterday where it was a constant 30 degree tilt.

Today's payout is looking a hell of a lot better than yesterday.  Should come close to doubling yesterday which is great!

How much of that is due to decrease in unexchanged balance? I have half the unexchanged balance I ended with yesterday, which makes my balance look better.

For me, both unexchanged and the main balance have been going up quickly today. Unexchanged is double it was yesterday and my balance has already well surpassed yesterday's payout. EU pool.

I don't know how you're seeing double the profits from yesterday. I'm at .053 so far today and yesterday I got paid .048. Yesterday I had .03 unexchanged, and today I have .022. At this rate, I'll probably end up getting paid about .062. Not double, but more than yesterday (and more than mining LTC straight!!)

Yesterday I had a deposit of .068 while currently I am sitting at .09.  I was just "guessing" that it would be double by payout time but that might be wishful thinking on my part.  Probably looking at closer to 50% increase.

Can someone explain why mt gox has higher price of bitcoin while everyone else are lower?

Didn't they already explain this to you multiple times in this thread? Even though this isn't the thread for that.

It's extremely hard to get verified to use Mt. Gox, so that means it's very hard to get money out of Mt. Gox. The price stays higher than other exchanges because a lot of people have money trapped there.

If I withdraw with bitstamp it means that I've lost like 5 days of mining. That sucks. I really hope it goes back to 915 $.

The bug we had, where we got 1% extra rejects that said "duplicate share" has been resolved.

[jam3zs]

Soooo I noticed it said "SICK" (R9 290) a few mins ago and thought it was weird that i had never noticed it.
Then a few mins later I saw the temp drop so i checked again and now it says "DEAD".
A full restart of the rig seems to have it back running but I don't know what would have caused it? Anyone seen this before?

[Zemou]

Today, I've got a lot of rejected hash rate.
On middle coin, I'm near 30% and on CGminer around 12%. I'm usually around 3-5%, am I the only one ?

First time this happen to me (I'm mining on Middlecoin for 4 months now), any idea ?

Did you overclocked your GPU ?
This happen to me when the card voltage is too low compared to my overclocking.

It also happens around 2-3 times a month for no reason.

Have a bunch of varied GPUs pointed to middlecoin for several months now, and wanted to extend a thankyou to H2o for fixing EU server again, having quite high ping to the US one from Sweden 

My question is regarding cgminer - should i bother testing other versions than the ones i currently use (3.1.0 and 3.3.1), if it somehow benefits multipool mining?

try to use 3.1.0 for my older cards (5870 etc) and 3.3.1 for R9's etc..

Either:

1) Too high overclock.
2) Too high heat.
3) Too high intensity.
4) GPU is dying.

You lost nothing because the Gox money isn't real. Even if you get verified, and send yourself a bank transfer from their site, it won't come. It hasn't for months.

I was having the "SICK" issue on my R9 290s quite a bit due to my settings. I was running the engine @ 1000 and the memory @ 1500 - the rig would run for about 2 hours before one of the cards would get sick. I backed the engine speed down to 985, and not only did the frequent crashes go away, I actually gained about 6 kh (from 856 per card to 862).

Well this is the config for that particular card:

Code:

 
 -I 20 \
 -w 512 \
 --gpu-threads 1 \
 --thread-concurrency 32765 \
 --gpu-engine 990 \
 --gpu-memclock 1500 \
 --gpu-powertune 11 \
 --gpu-vddc 1.025 \
 --device 3 \
 --remove-disabled \
 --temp-cutoff 99 \
 --temp-overheat 95 \
 --temp-target 85 \
 --auto-fan \
 --gpu-fan 50-85

It doesnt give any HW errors like this.
It does run hot but all 290's run hot (85c - 90c, although I have seen it go over 95c once before).
It's got it's own psu to it's self.

Hope it's not on the way out, not had it long lol.

[ratty]

Use a program like CGWatcher that restarts it if it gets marked as "dead" or doesn't submit any shares in X minutes. It can also reboot the computer if a restart fails to fix it.

jam3zs you should increase voltage or lower engine, simple as that.

Btw, we have reached moon it seems

Doesn't matter when I've lost 100 $ today.

And also remember that since BTC value has fallen today some people will think we have earned more money compared to previous days but thats not the case.

Then wait it out. it's gonna reach that soon again (Probably, if not i'm fucked too )

[jam3zs]

fuck!! 5 mins later and it's dead again!

I think i will bring the gpu engine down and it needs a new psu anyway, the one it got is some random shitty old one i found laying around.

Just weird that it's only just started doing it.

I'm still trying to figure out why some people had such a low payout from last Saturday, so I made a nice comparison :



As you can see, all miners have more or less the same hashrate. Yet they have a very different payout and remaining balances (for the immature/unechanged balances).

Some observations I made :

1)
It looks like the pool is using the unexchanged balance as a multiplier, i.e. to play with. The only ones having a decent payout or the miners that had a lot of unexchanged carried over from the day before (miners 2, 5 and 6). Note that the actual unexchanged balance remained the same at the end of the day. Don't know what to think of that..

2)
Some miners had part of their unexchanged balance changed to their balance just before the payout whilst others hadn't (miner 1 vs. miner 0). What gives?

3)
Miner 3 is a nice example of a miner that basically started the day with a clean slate. Yet it got a better deal than miner 0, even though its hash rate is lower. Huh?

As you may have guessed, miner 0 is me.. I changed from EU to US about halfway through Saturday as was recommended by the pool operator in this thread at the time.


I really don't understand what was going on last Saturday, but judging from the above comparison it doesn't look right to me.

I am worried that there are bugs in the system that are costing some miners their due payout. Also, if the pool is using the unexchanged balance as monopoly money to increase profits, fine - but why isn't this the same for everyone?

---

I've also tried to relate the graph for the pool as a whole to the individual miners. Somehow I would expect them to be very similar except for the scale :



Yet they do not look similar at all, except for the miners that got a 'regular' payout.

Anyone want to share his/her insights?
