On x13mod sph-miner mining my 290/290x rig is slowly losing hashing speed over a period of hours. I thought it might have been due to undervolts or clocks, but the behavior is remaining after removing any undervolts and keeping clocks below stock.
Same version of sph-miner is not showing this symptom on 280x system or 270/270x system.
Any ideas? The clocks on the 290/290x gpus are solid to where they should be, but memory is intermittently dropping to 150mhz on a continuing timeline which my other rigs are not doing.
I believe I've seen this issue show up independent of the version of sgminer i'm using and that it's followed 290/290x as well as r9 270 cards.
is x13 running as cool as the x11?
I'm loving the x11 algo... cut 20-30 degree temp in the house and using less energy... so much so, that i can bring more gpus online... i was at my power threshold for the house running scrypt.. and the dog didn't care too much for the heat, the cats didn't mind to much though, they prefer scrypt over x11

The 24 hour payout stats for x11 on Nicehash is horrible. Around 0.00036 BTC/Mhash. Unless things pick back up going to have to go back to scrypt. Less electricity and heat is not worth 1/6th the gross earnings.
Very similar. I'm finding I need more volts for a given speed to run x13 on my 290/290x, but other cards (270/270x/280x) appear unaffected by this. I'm using roughly 5-8% more watts running x13 at a given clock rate vs x11.
Temps and power draw on x13 are much better than scrypt or scrypt-n.
x-11 profitability has dropped like a rock. From .0018btc/mh a week ago to .0004-.0005 range today.
That is sad when it comes to an enthusiasts when our fans hit 100% (Which is about 1500 rpm for a 140mm) at 80C under water with temps never going over 68C and Hawaii doesn't throttle at 1200 x1500Mhz's under full load 1/2 fan and QUIET."auto-fan" : true,

What's the preferred miner for X13?
Could you still make a profit on those cards? I would think the electricity exceeds the profit.
has anyone been able to get 5870/5850 to run on either x11mod or x13mod? I get nothing but HW errors, but they run fine on the regular x11 (darkcoin) kernal.
Something is driving up the prices of X11 rentals. Nearly all of the large X11 farms on Betarigs are booked.
I still think that we should launch our own altcoin. The real money seems to be in getting in on the ground floor while mining is easy and coins are cheap, and cashing out once is gets popular.
