Looks like Darkcoin is a total loss so far  

What do you mean?

Have not seen any showing on stats and nothing earned so far ... been 7 or 8 hours since it started showing up on stats graph ...

Seems well within reason however.  Looking at last hour (I haven't been watching that closely) we've been mining it a pretty small portion of the time (12% at this time), so of that 8hrs, its really only been about an hour (call it two for argument).  With 2ghs hashrate, we're looking at an average block time of around 2hrs, so we're easily within that (just based on stats, with 2ghs mining, we'll regularly see 6+ hrs of mining without a block (and at 12-25% of our mining time, thats pretty much a full day).

This is the main reason we had it disabled until we had 2ghs+

The fact that this is just newly in Beta and profitability is on par is very impressive. I have 450Mh/s+ now pointed at the pool.

So, I'm guessing you still have most of your GPU's.  It been a while since I've seen you atomic! Hope all is well.

Yep, they're all pretty much on auto-pilot, but I switched to X11 lately as my tonnage required for cooling my operation exceeds 15 tons, and I'm about 5 tons short for another couple weeks. The GPUs are chugging along... Making about what I did when I started in April of 2013, so it's still profitable.

Awesome!  Its essentially not in beta (we haven't had anything larger than display issues on either Scrypt-N or X11), just need to finish writing the documentation and guides for how to mine X11 (and redesign the index page to fit it all) before I mark it fully open

Good to hear!! I'm still on GPU's too, but not nearly on your level.

Nice! found a CPU miner for X11 on Core2 Quad Q6600:

Do you know if CPU miners are profitable with X11 due to lower power usage or are you just experimenting for the heck of it?

Don't know ... might as well as the CPU's are not doing anything else but running sgminer and seems to have no impact on GPU mining.  X11 definitely more profitable

I was more referring to the power usage vs. profit ratio. Unfortunately "not doing anything" isn't a good approach these days as profits seem so thin.

Here is some math I did a while ago for an i7-4771. Older CPUs lacking AVX/AES instruction sets will perform a lot worse.

Hashrate using all 8 cores: ~0.3 MH/s
Power consumption: ~70W, 1.68 kWh per day
Cost per MH/s per day at 0.1 USD per kWh: 0.56 USD

Now if you look at Waffle's recent X11 profitability, it's around 0.0007 BTC (I hope I got the zeros right) or 0.45 USD per day.

To break even you'd need to earn > 0.0009 BTC per MH/s, or have access to < 0.08 USD/kWh electricity.

EDIT: just to emphasize the scale: even if you had free energy you'd be making 15 cents per day on a $300 CPU.

[utahjohn]

Thanks for doing the math.

page 61 of the thread you referred to :

...so I forget that I had installed Catalyst 13.1,
Now it's working.
So definitely for others, Catalyst 13.1 is not working at all with this miner...

Hehheh,  he must have posted after I read the last page and then started reading from the beginning.

I finally got the x11 going though.   That driver stripper program did not really work for me,  I don't think that it recognized the modded 13.1 catalyst driver that I had originally installed. I don't really know.  I ended up installing the stock AMD 14.4 driver program and let it strip out the old drivers, with one card throwing the 23 error, and then initiated another install and midway through added a mod for 14.4 to allow for 6+ gpus as described in the link below:  

https://lbr.id.lv/Coin/14_4_mod_v3/14-4_mod-v3_README.html

The link contains links for stock AMD 14.4 driver and 14.4 modded files,  and implementation instructions.

I finally got it going a couple of minutes ago.  There were some other little hang-ups along the way,  but nothing remarkable.  

I'm seeing an average of 15.1 Mh/s, and much lower temps than before, seeing about 5% rejects over on useast, but have not tweaked the config yet.   I'll be interested to hook up my kill-a-watt to see what I'm drawing now.  Before I was pulling ~16A mining scrypt and scrypt-n,  so I'm expecting to see around 5 or 6 less amps mining the x11.  

I see that the miner detects new blocks repeatedly without accepting shares,  and then will accept a share
every so often.  Not sure if that is normal,  or if I need to set share difficulty or something.   it auto-set to .160 at this time.

At least it seems to be running without any hardware errors, and it is accepting shares,  so I can now feel like I can proceed productively with tweaking the config,  unless you guys see a problem with the repeated block detection before accepting a share.  I'm not sure if that is normal and have not had a chance to search about it.

At 3Mhs I have D=0.008, PW said 0.008 or 0.016 for my hashrate.

I have set my password to d=4096 for my ~12Mhs Scrypt ASIC rig, but it seems it is stuck at diff 512.
Any ideas?

Hi to all.
I want to share my experience with x11 algo for my 2 rigs (4x Asus R9 270 (non-x) and 4x Sapphire R9 270 (non-x) too)...

...Is it possible to reach 2,0 Mh/s per card ? Any suggestions ?

That's what i use for my 270:
0HW ~ 1 - 1.5%reject ~ 2.02Mh/s

At 3Mhs I have D=0.008, PW said 0.008 or 0.016 for my hashrate.

Ok, cool.   This was bugging me though.

(Following quote taken from wafflepools new algos x-11 info page.)

 " Password: Any. "d=XXX" accepted to set difficulty (0.008 up to 2.048, powers of 2 only). "

If you go with a power of two on either of those numbers,  you'll move higher than the largest or lower than the smallest example given.

I'm wondering if he means factor of 2 only.

Something like this?

0MHs - 1MHs   d= 0.008
1MHs - 2MHs   d= 0.008 
2MHs - 4MHs   d= 0.008   or  0.016
4MHs - 8MHs   d= 0.032   or  0.064
8MHs - 16MHs   d= 0.128   or  0.256
16MHs - 32MHs   d= 0.512   or  1.024 
32MHs - 64MHs   d= 1.024   or  2.048
64MHs - 128MHs   d= 2.048


I have not tried to set a difficulty yet,  so I don't know if the above examples are what he has in mind. 

***************************************************
(The next info should probably go in the lasybear miner thread but I am putting it here anyway.)

I just started tuning my config for my sapphire HD7950 cards.
( 11196-19-20g )

With the lasybear x11 sph-sgminer,  I'm hitting a per-card ceiling of ~2.95 Mh/s before the rig starts bitching, with a per-card average WU of ~.045 or so, and the rig is pulling ~8.15A so that is a lot better than I expected.   

I might be better off with slightly lower hashrate and lower amp draw though.

I did get one sick card once due to inactivity/something.  I know that I had read about some others with that problem too,  so I'll have to look into that some more and see what's up with that. Not sure that I trust my config just yet.  It's close to maximum efficiency,  just not sure about the stability yet due to that sick card that popped up once so far.

[Uniphase21]

hey guys

I made a previous post about this and I am struggling. Is there a place to find some good information about what is more profitable between scrypt N and X11 or X13?

Thanks in advance
