Hi All,

As Australia has just come out of summer, and the Europeans and Americans will start to heat up soon I wanted to give you guys a look at the stats of mining Darkcoin which uses the x11 algorithm!

I can say that compared to the previous summer, having x11 was a dream, no more loud fans, no more overheating rigs, no more crashing and having to monitor my rigs so much.

I have 4x Gigabyte 280x video cards in each rig and are currently slightly undervolted. I have compared it against the standard scrypt algorithm and had the same machine mining until it hit a stable max temperature. The tests were done about 15 min apart from each other.

As you can see the results from mining x11:
Temps are around 20 degrees cooler
The kilowatt measurement shows a 50% reduction in electricity usage

Having one of the most innovative dev team's (first anonymity coin) and great communities I must applaud the Darkcoin team for developing such a great algorithm which will surely become more widely adopted in future.

For more info on how to start mining this coin please see the ANN thread: https://bitcointalk.org/index.php?topic=421615.0

Give credit where its due. This guy was first, maybe the same guy I don't know.

https://bitcointalk.org/index.php?topic=422149.0

Doesn't look like it, Darkcoin was first on 18th Jan, this guy was 19th Jan.

please do research, post date 19th january for your link, and

and, 18th january for darkcoin see link:

https://bitcointalk.org/index.php?topic=421615.0

So, credit, where credit is due, i think he already did so.

Also notice topic id for darkcoin is lower, meaning, posted before chaincoin link

Easy setting for R9 280X ~ 2180 MHash:

I 13
w 256
g 2
thread-concurrency 8192
gpu-engine 1050
gpu-memclock 1500

46-52C in an open case setup with a big fan (in scrypt 68-72)

2* Sapphire HD 7950 with boost ~ 3MH/s

I 18

54 - 59C (Ambient temp 28C) in a closed case (Corsair Obsidian 650D)

Anyway i don't even understand why people mine this stuff as it's not profitable at all...it would cost me money to mine it & sell it

All this means is that the X11 miner is poorly coded and not taking full advantage of the GPU.

The public miner, anyway. No doubt there's a private miner out there that's 100-200% more efficient.

anyone is more than welcome to improve on the gpu miner

video cards will love this summer with X11.

Good job.

great X11, great darkcoin!

My GPUs were at 80°C at 3000 rpm , now they are 60°C at avg of 1500 rpms , with much lower power consumption.

But these coins are not profitable. That's the main issue why I went back to mining regular scrypt.

I don't know how you came up to that conclusion. Right, now you're getting 0.0077bmg for Hirocoin, which is higher than middlecoin (0.006) and you're paying 2x less electricity. You were right to some extent, X11 is not more profitable than scrypt, it's MUCH more profitable :)

Haha you are so funny  ;D If this cost money for you then you are in the wrong way !!! If you often selling what you mine you are totally wrong... This game is not for such people and if continue to do that you will be dropped from the train by yourself !!!

Please explain how do you understand "profitable" ?

Most people don't mine to sell immediately. If you do, most coins are not profitable for the majority of miners if you take everything into account (investment, power consumption, time). Most people mine for fun and the promise of future profit. Can you do the same just by buying in an exchange? Definitely, I usually do, but it is not the only way.

I see the same values for my GPU rigs.

Mining HiroCoin for days now and GPU rigs are running very cool, power consumption 45% lower :)

Im getting different results then most with the temp findings.  I find it to be running cooler but the numbers people are throwing out there seem crazy.  My rig avg temp mining scrypt is 77C using engine:1000 mem:1375.  Mining Darkcoin im at 73C using engine:1050 mem:1400.  That is less then 2% cooler for my end result.  I think it's fair to compare the different OCs as I think many others will OC more on x11 because they can push further then scrypt,  I just don't get where people are coming up with this 30% cooler and such.  Many of the screen shots don't mention anything about uptime, did they even run long enough to get to full temp?  Overall I do find x11 favorable to scrypt and I havn't even been hit by any warm weather yet.

Something is off with your setup, perhaps there's no airflow and in scrypt the only thing keeping 77C is GPU throttling?

I have several rigs, fully open (no case), open case, and every single card is running more than 30C cooler.
I even don't need to open windows fully anymore  ;D

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.

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?

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.

I have a theory that temp-target is causing this, how about if you try to run only with the minimal settings and let the GPU manage itself?

Try set only:
intensity, worksize, threads, gpu-engine, gpu-memclock and pool config?

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.

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

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

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

I agree with you  ;)

What are you using for mining? I used sph-sgminer https://bitcointalk.org/index.php?topic=475795.0. Is this the one most of you use? Are there better ones out there?

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"

   }

"auto-gpu" : true,

}

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.

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. 

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

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

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.

Is it current gen. ASIC resistant?

Yes, x11 is a very attractive algorithm... :)

Great, thanks for the recommendation.

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

He's just trolling.

nahuh I got nearly 6mh per 280x here :P you gotta use some crazyass tor search ;)


but sersly x11 is like how bitcoin was this time last year, kinda exciting, no body knows whos doing what where how whyyy?!

 yeah i just got it and i am getting around 5mh with my old 7950

Would someone mind posting an example bat file for sgminer for mining Darkcoin?  I'm thinking of puchasing a few 280x GPUs.  Thanks.   :)

Interesting. These experiences are very useful, thanks for sharing your experience, I want to try.

i am pretty sure after more search that there is a better miner than the private one i have
some people are getting some crazy shit hash 1.5GH to 2GH but don't know with what hardware they are doing it (ASICS perhaps?)
these mining world is plenty of assholes and scammers .... i continue to mine x11 till my miner goes public 

Shed a little more light on this my friend?

Could you please tell us more about this miner? Thanks a lot in advance.

All the claims of a secret super-optimized X11 miner out there but absolutely zero proof. Not even a screenshot (easily faked of course, but still not even that). How bout we show some real evidence, or even better the actual miner. I'll happily throw some bitcoin your way, and I'm sure others would as well...except I don't think it actually exists   ::)

Not necessarily. There are different components (producing different amounts of heat) in a video card that can or can not be used in a miner of certain algorithm(s).

Could you expand on this? Is there a way for 'equal effort = equal reward' across the algorithms? Maybe it is just hype if this is not a real solution

Mining DARKCOIN is like a BIG piece of ICE for me, on this summer comming in ITALY !!!

Satoshi bless X11... I've fired up my 5x 280x again  ;D

the 280x bat looks like: sgminer -k darkcoin -o x -u x -p x -g 1 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8191 --shaders 2048
280x~2.15-2.2mh/s

thanks

I am wondering what effect xintensity, rawintensity and thread concurrency actually have on the hashrates. My baseline hashrate according to google search for my r9 270x is around 1350. I got mine bumped up to 1420 running stable and can push it up to 1475 or so. What I am curious about is what multiple of our shader should be used for x11

any suggestion on settings for r9 270 msi smos/bamt?

I am stuck at 1320ish, I have heard people getting up to 1360kh

the old miner just went public :)
you can find it here https://www.dropbox.com/sh/zhfbr8xh6zw0gi0/AABpOqIB8QvMfCnpV_2MPLoia/x11-sgminer-win-x86_64-build1.zip

you can get 3.5mh on 280X with the right conf ;)

still far away from the private one

Has anyone tested this file?

Really? What miner are you using? I get about 3800 KH/s with X11 and this is at 300 watts. If I were to mine DRK today at 10 cents per per MW/hr I would LOSE 41 cents. Scrypt is more profitiable in every instance that I have tried. Please show me the numbers, because if you are using the same sgminer that 99% of us are you are likely not paying attention to the numbers. I just cannot see how X11 has gone this far with so little recognition of this problem.

Here let me make it easy for you. How much hashing power do you have and what is the killowatts reading at the wall? I will show you right here if your claim is true or not.

2880 with scrypt, 1200w from wall
12400 with x11 , 600w from wall

have fun
