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

[DrunkenDonkey]

And if it was the reverse, you would be happy....

don't like this, go mine on MegaMultiPool, or somewhere else 

Nope, we'd be happy by the big paycheck, but not if that happens because of an error in the system and somebody else suffers from that. We all should get what we worked for. Otherwise, I'll start checking the servers using some accounts, or will connect some single miner to each and see which is the most profitable and do daily switching, that will overload single servers while making the rest blank and we will all suffer.

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.

Somebody please give me their timings for CGMiner , It's giving me a headache , I'm losing heart to be honest.

I've seen somebody getting 1 share per min per R9 290 but I can't find his timings.

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 ).

[Thomza]

Is it safe to be on amsterdam/eu server now ?

[bosom]

My hashrates shown on my machines have all dropped by about 5-7%.. I was getting about 730 per 280X, now they are getting about 690kh per each or less.  The ones that were getting about 700kh before are now down around 650kh or less...

Nothing changed on my end... I'm on useast currently, temps all under 70C... just wondering if something changed server side that would cause lower rates?

I was using that first hour i started mining and it wasn't any good imo, Thanks though.

Are you still using Guiminer ? Because i can help getting CGMiner working if you like.

Thanks a lot for sharing your set up, I tried 15 scan and 15 expiry but it gave me poor results. Just curious , How many shares per min are you getting ? Because you have more or less exactly the same setup as mine, I have two Sapphires.

I've not had a problem with sick or dead, I've had them clocked at 1000 core 1500 memory for weeks and they never gave an issue like that.

How many shares per min you getting each card ?

[iarsenaux]

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.

Not awful, But not great, What server are you on ?

last hours shares: 143/147
around 1.2 share per min per card

I fail to see the beef with the EU servers, I got 0.21/MH yesterday

No way , I'm getting 1.5 shares for both cards per min , What the hell is going on ? I must be a nut case or somethin, I can't see how your cards can be nearly twice as many shares as mine.

Hold on I just noticed , Your temps are 54.0c ? Are you watercooled ?

How many shares per min you getting each card ?

Usually I get about 0.8 share/min per card.

Could be a number of things, I'm leaning towards the mobo though (some are on powered risers but that doesn't seem to matter), an Asus P8Z77 WS with a Lucid chip on it (I missed that bit when I bought it, otherwise I would have avoided it). Also, I can't seem to get the rejects below 4-5%, even at I13 (which gives me really poor performance) or I18. Ditto for another rig with 7970/280X (same mobo).

Just luck. With a WU of 767/m, you get about 0.75 share per minute (767 WU /1024 share diff).

I can understand luck being involved if it was slightly higher but that's loads

I have a 280X doing 1.15 right now. That's just not mathematically possible over the long run. Luck.

What server are you on ? I've just switched up my settings and in still only getting 1.5 shares per min between two R9 290s

Vanilla middlecoin ATM, but I get high rejects (still the payout is better than the other ones with lower rejects). My rigs don't like useast at all today, but that was my main server. Eu and amsterdam offer good WU and low rejects but also lower payout still.

1.5/m with 2 R9 290 is what you'd expect for a hashrate of 850KH/s per card (WU is about 0.9 x 850 = 767 and U is 767 WU / 1024 share diff = 0.75 per card so 2 cards = 1.5).

850 is what I get with I18, core at default and RAM at 1350.
