Very interesting analysis would be good to hear some expert opinions

Awesomes....

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?

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.

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

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.

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

Btw, we have reached moon it seems

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.

Well this is the config for that particular card:


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.

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).

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.

Either:

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

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..

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.

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 ?

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?

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

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 $.

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.

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.
