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

Thanks!

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.

Thanks for doing the math.

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.

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.

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

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?

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

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

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

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.

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.

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.

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+

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 ...

What do you mean?

@PW
Looks like Darkcoin is a total loss so far 

page 61 of the thread you referred to :


Do a system backup using EaseUS Todo Backup Advanced Server 4.0 or newer and give it a try lol.   (This can be found on most p2p torrent sites).  http://thepiratebay.se/search/EaseUS%20Todo%20Backup%20Advanced%20Server/0/99/0

Be sure to create a restore CD or bootable USB flashdrive ROFL

Hmm,  do you know if that driver will run six cards?  The driver that I am using now has been modified to do so.  (Because I'm running Win8. )

I'm reading through the x11/x13 miner thread for more clues,

( https://bitcointalk.org/index.php?topic=623409.280 )

and I'll probably start posting in there if I can't figure it out.

The last thing that I want to do is change anything with the current driver that I am using,  since it is modified to run all six of my cards.
