ok. so i've been hashing for 12 hours and only got 0.018btc with my 4.3 to 4.6mh/s rig. very interesting.

Try guiminer for 290 if all else fails, i had trouble with cgminer and sgminer running this card, especially thread concurrency. Something to do with AMD driver on new non reference cards.

For the Sapphire R9 290, I only need to specify threads 32765, gpu memory 1350 and I get 880H/s. Changing core clock makes no difference over time (and you SICK/DEAD if you go too high).
It doesn't like memory 1500 much ether, some cards lock up after a while. 1425 gives 890KH/s but 1350 has been rock solid (1% less KH/s and a good night's sleep vs 1% more and checking all the time...hmmmm ).

Confirmed that last payout was really crappy. I was mining on Asia server.

I (mining at Amsterdam) noticed the same issue and yesterday H2O confirmed (on IRC) that currently not all servers give the same profits, but he is working on a fix. Excerpts from a chatlog (with other news as well):


Jan 31 22:23:03 <Acrobat>   Do we know why the difference in unexchanged between different MC users is so enormous? Are you screwed when mining EU/Amsterdam instead of US?
Jan 31 22:31:35 <h2odysee>   Acrobat: I know that's an issue. In the future, it won't matter what server you're on.
Jan 31 22:31:47 <h2odysee>   I'll make all shares equal
Jan 31 22:33:15 <h2odysee>   The difference in profit between the various servers should be smaller now, than it was before.
Jan 31 22:34:48 <h2odysee>   well, they should be. I made a change a couple of days ago that should make them more equal
---
Jan 31 22:39:43 <h2odysee>   current plans, for those interested, are to fix the amsterdam server (I think I know why it disconnects a lot), then set up a new system for rolling out new servers.
Jan 31 22:40:11 <h2odysee>   So I will be able to easily provision new servers
Jan 31 22:40:38 <h2odysee>   Once that happens, we'll get a Dallas, LA, and Hong Kong server
Jan 31 22:41:03 <h2odysee>   both Ireland and Amsterdam suffer from the same problem. I don't know if either is best
Jan 31 22:42:28 <h2odysee>   I could do a Frankfurt server maybe.
Jan 31 22:44:48 <h2odysee>   Scandinavia will be low priority, because none of my hosting providers have datacenters there. I'd have to use a new one.
---
Jan 31 22:46:27 <h2odysee>   Yeah, the current load issues are the main thing
Jan 31 22:46:33 <h2odysee>   Which I can solve
---
Jan 31 22:47:27 <h2odysee>   I need to lower the diff again. But I can't yet.

Well i didnt have such a nice payment today, im on the asia server, received less then 0.01 BTC/mh today, actually alot less.

Hopefully onwards and upwards tomorrow.

We use one profit pool and that is middlecoin, now it's spit up like different pools.

As said before it should be: BTC's earned on all servers >> divided by all shares submitted on all servers>> multiplied by user shares >> is payout

can someone explain this?

Just lost every rig other than the ones that are rented / not on MC O.o

Everything is fine on my end... just looks like we lost all servers for the time being (I don't have the Asia or Amsterdam ones configured, just USEast/EU/Default)

Shaping up to be the best payout for me so far, ~0.02BTC/Mhs or so, despite higher than usual reject rate. Higher rejects are regrettable, especially on a good day like today, not sure if there is anything more I can do about it on my side.

So its your destiny to have crappy payouts and by solving the other issues the only way to get rappy issues is to fuck up the whole pool ... Thanks a lot ...

From the miner log I can see that we're mining a lot of a low difficulty coin (or several), and it could be that the value of those just don't show up in the immature/unexchanged if we're trading them on an exchange where middlecoin doesn't have access to the API.

then go cry in the cryptsy thread? 

it could also be an issue with the exchange... ever thought of that?

A: Taking a chance with a new coin that may blow up (like DOGE back in December)

Ah OK. But he did say he's getting ~720 on stock clocks from a 280X which I find equally outlandish?

I have identical "issue" with my miner today (amsterdam server).

my total balance has rise from 0.0441 up to 0.0585 for 6 hours.  on 7.5mhs

Not sure why you're saying the KH you're getting is at "stock" clocks.

What's up with the unexchanged number of btc increasing?

It's getting to an excessive amount lately...
