He's just trolling.

Could you share it? i tried to find anything like that, but i probably used not as deep web as you did

Great, thanks for the recommendation.

Yes, x11 is a very attractive algorithm...

Is it current gen. ASIC resistant?

Actually you are the funny one lol

There is no point to mine for a higher cost than the market price, you rather directly buy the coin.
If you cannot tell this is nonsense you should not be into cryptos, you may loose big.

It may be the case because of what Hazard said, some people with a better gpu miner can dump coins they mine way cheaper than you.

I agree with Hazard. Someone out there is laughing at this thread right now. The GPU is simply not being fully utilized.

hehe  you are right around 3 times more efficient i can see 6.23mh per 280X
checkout the deep web

no doubt - but i still think 100 or 200% is acceptable for cPoW which is what X11 come under SIF being the original which Quark followed on from. 

Chopped alot of crap out of my config and made huge difference.  I had sgminer write the config for me and made just a few adjustments to it, weird.  I dont have the time to mess around with which line did it exactly but I hacked my config down to this:

{
"pools" : [
   {
      "url" : "stratum+tcp://stratum1.suchpool.pw:3335",
      "user" : "EDITED",
      "pass" : "x"
   },
   {
      "url" : "stratum+tcp://stratum2.suchpool.pw:3335",
      "user" : "EDITED",
      "pass" : "x"
   }
]
,
"intensity" : "13,13,18",
"worksize" : "256,256,256",
"gpu-threads" : "2,2,1",
"thread-concurrency" : "8192,8192,15232",
"kernel" : "darkcoin,darkcoin,darkcoin",
"gpu-engine" : "500-1050,500-1050,500-1100",
"gpu-fan" : "0-85,0-85,0-85",
"gpu-memclock" : "1400,1400,1500",
"auto-gpu" : true,
"kernel-path" : "/usr/local/bin"
}

About the same hash, one 7970 at 50C the other at 52C. Scrypt was at 77C. Huge difference. About 8% cooler then mining scrypt.  Good suggestion Luke997. 


Playing with setting more I notice the following:
Auto-fan on and having the gpu-fan from 0-85 together causes the problem.  Without actually looking at my fans, I think its trying to turn my fans off.   I notice that randomly for a split second it reports fan speed of 9999RPM but then goes back to showing super low RPMs, in the 1000s.  Setting auto fan on and changing gpu-fan to "40-100" causes temps in the mid 60s and no more 9999RPM showing up.  Seems drivers or whatever controls fans normally works better then having sgminer control it.  No auto-fan puts fan at 3500RPM, which is a little loud, ill tune a quite fan speed to temp ratio I like later.  Changing the target temp might fix the problem as well so I think Luke997 was right on.

What are you using for mining? I used sph-sgminer https://bitcointalksearch.org/topic/ann-sph-sgminer-multi-coin-multi-algorithm-gpu-miner-added-marucoin-475795. Is this the one most of you use? Are there better ones out there?

I agree with you 

no coin is profitable at the moment, unless you are instamining new coin and  in that case the algo used mean nothing...

They have. And they're keeping it to themselves.

It is very profitable. Especially where electricity is expensive such as Australia where it's 0.26 per kilowatt hour.

sorry to say this guys but x11 is just groestl + quark it does 3 times better on gpu than on cpu (as groestl standolone does too) but considering cost and power it's pretty good ... just not the breakthrough it is hyped to be.

I have to leave for several hours but thanks for helping.  Could be the minor OC makes that big of a difference, dont get me wrong it is cooler, just not nearly as much as others are reporting.  When I return ill post some data with the same OC settings, maybe im comparing apples to oranges.

Something is wrong, haven't heard of anyone yet with so insignificant difference between X-11 and scrypt.
What version of sph-sgminer you have and what exact settings you run?

Im running full open rig, risers and as much distance as they allow, about 3 inches between cards. No gpu throtteling, 700Khash per 7970 scrypt, 2.05Mhash running darkcoin.
