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.

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

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 ?

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 ).

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 ?

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.

[rahrahrah]

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.

My 2.6MH/s rigs made 0.033 in a full 24 hours against the EU servers. Trust me in that you can't predict performance after 12 hours. Massive changes can happen in a single hour.

Is that with powertune applied ?

I am getting a heck of a lot of work restart requests from middlecoin.  It's basically killing my WU, which means I'm leaving money on the table.  I'm pretty sure it's because of whatever's going on on their end too.  It's getting damn annoying.  Basically seeing about 83% here.  That just ain't good.

[SkillRoad]

Is something wrong? I am at work and miner at home, But nothing is accepting, I have Useast with failover to Main server middlecoin??

Accepting 0Mh/s

Check your stats now. Mine stopped showing up, but cgminer was alive and well spitting out WU.

Just FYI, given the outage yesterday, y'all can guard against having your rigs completely offline while still using the specific servers you want when they're up.  

I'm in the US, so the below cgminer.conf snippet splits 80% of my power between US East and West, 20% to wafflepool, and falls back to non-US Middlecoin servers if the first three are all down.  You can play with the quota numbers to create whatever behavior you want (making Wafflepool a last resort, load-balancing evenly among everything, etc).  It pretty much makes it set-and-forget.

I had about ten work restarts in a min today

Yes, powertune 20.

Try wafflepool instead, i think its better.

[sykal]

damn wafflepool is def growing quickly

[mikeybit]

Anyone else get accepted into poolwarz??

Curious to see if anyone's tried it yet...

[KS]

damn wafflepool is def growing quickly

Yes, so much so in fact that it lost about 10% of its hashrate since this morning. I wonder if those are ppl coming back to Middlecoin

edit: was 878MH/s this morning with 712 miners, now down to 791MH/s and 701 miners.
