Topic: [POOL][Scrypt][Scrypt-N][X11] Profit switching pool - wafflepool.com - page 60. (Read 465674 times)

Is it normal the reject ratio on x11 is incredibly low? I'm obviously not complaining, but I'm suspicious, just in case it indicates something is wrong with my settings. I set my rig up for x11 last night, it's hashing at about 9 MH/s, and until just 5 minutes ago, I had no rejects! I had over 500 accepted shares, and 0 rejects. Literally now, as I'm writing this, there's been the first reject, so my reject rate is now 0.188 %.

Wp seems to be tracking my rate and earnings are going up, but still, I thought it was a little too good to be true, so I thought I'd better check.

Thanks suchmoon (and utahjohn and his posts with his config files) in particular who helped me with the setup.

Thanks of course goes to Waffle too, for his continued work and improvements on this awesome pool! 

Take a look at utahjohn's post too. His setup seems to be better tuned than mine:

Thanks. Your tips helped me as well.

Copy/Paste is hard man.  Writing a decent pool, no problem.  Copy/pasting instructions for how to use said pool, way harder


Added, sorry about that

The table title X11 quickstart is titled "Scrypt-N Mining". Don't you hate those copy/paste errors? 

Don't forget nvidia in your How-To ^^

ccminer: https://github.com/cbuchner1/ccminer/releases
Example: ccminer50.exe --algo=x11 -o stratum+tcp://eu.wafflepool.com:3331 -u your_bitcoin_address -p d=0.016

Ps: For X11 the title is "Scrypt-N Mining" instead of x11 and wrong port Number in your example

Great news PoolOP!! Thanks! It's working great so far!

X11 is fully live.  No longer opt-in, and shows in the header/homepage with a getting-started guide.

The password-based difficulty is a lot more flexible now as well, allows any value from 0.008 to 2.048 (not required to be a multiple of 0.008)

Card 0 is 280x, card 1 is 7950

With the 280x and 270x you probably should try more gpu-threads, not sure about 7950, I'm running it myself with gpu-threads 1

Try higher intensities. 15-16 with gpu-threads > 1, 19-20 with gpu-threads 1.

You should get > 3 MH/s for the 280x, > 2.6 MH/s for the 7950.

suchmoon, thanks VERY much!

I've succeeded in getting it going just before I saw your reply, I'm very pleased with myself!

It's fantastic, it's drawing 520-ish Watts instead of 970-ish when it was mining scrypt.  The temps are much lower too and the fans are barely spinning!

Now, I've left everything on default as per the provided example x11mod config file, and just copied a few lines from the old scrypt config file.  This is the current file I'm using:

(the cards are: 280x, 270, 280x, 7950)

"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",
"auto-fan" : true,
"expiry" : "20",
"gpu-dyninterval" : "7",
"gpu-engine" : "0-0",
"gpu-fan" : "15-70",
"gpu-memclock" : "0",
"gpu-platform" : "0",
"gpu-powertune" : "0",
"gpu-threads" : "2,1,2,1",
"gpu-vddc" : "0.00",
"intensity" : "13,18,13,18",
"kernel" : "x11mod",
"kernel-path" : "/usr/local/bin",
"log" : "5",
"lookup-gap" : "2",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"shaders" : "0",
"shares" : "0",
"temp-cutoff" : "86",
"temp-hysteresis" : "3",
"temp-overheat" : "80",
"temp-target" : "69",
"thread-concurrency" : "0",
"vectors" : "1",
"worksize" : "256"

I left the gpu-threads alone from the old scrypt file, where 280x needed 2, and most other cards 1.  Should I change them all to 2?  Or 4?  Not sure how this works in X11.  What about recommended intensities for these cards?  Also, I didn't specify the difficulty in the password, and it's automatically been set at 0.160.

I'll leave the engine, memory and tc alone for now, small steps.  

This is what it's looking like right now:

I think you're on the right track. Try x11mod kernel, it should give you higher hashrate. Intensity with this kernel should be 15 or 16, and gpu-threads 2 or 4. Other settings can remain the same, eventually you might want to try tuning further, but first try to get it running.

I'd suggest to start with d=0.008 or d=0.016

Does anyone else on x11 wp mining seem to have their miners go dead more often?

On Scrypt I used to never touch the things on Scrypt, but it seems at least once a day I have to restart the miners on x11. It seems even on my one gridseed miner now that's Scrypt, I also loose wp stats (it declares it dead) 1-2 times a day. The miner at the computer terminal still says it's going, but it doesn't seem I get any credit on wp. Once I restart the miner all seems well again.

Ideas?

Can anyone help, I'm really struggling, and have now spent hours trying to figure this out.  Excuse the newbness of the questions in advance.

I've been mining scrypt on WP for months now, nearly from the beginning, on the rig I built, which was running BAMT.  It was all working fine, but I now want to switch to X11 due to the fact it runs cooler, uses less energy, and should be more profitable than scrypt.

Someone on this thread, a few pages back, gave a link for PiMP (www.getpimp.org), which is some new OS that's multi-algo, and supposedly very easy to use and reliable.  Well, I'm not getting far with it.  I've managed to image a USB stick, and boot the rig with it, and I get into the GUI.  Where I'm struggling is I simply don't know how to set up the config file for X11.  I have my config file from the BAMT, when I was running scrypt.  Can I copy most of this file, and only change a few lines?  Obviously, I know I need to change the ports from 3333 to 3331.  Do intensities, tc, gpu-threads, etc, remain the same, or at least similar?  Most importantly, I don't know what to put in the line where it says "kernel:"  PiMP provides several example config files.  There are two X11 files, called config.x11.conf and config.x11mod.conf. The first one says "kernel: darkcoin", the second one "kernel: x11mod".  Which one of these should I be using?  Are there any other crucial and important differences in the config file which are different from a config file for the scrypt algorithm?  Anything else I should be aware of?

Finally, I have no idea what difficulty I should specify.  My hash rate on scrypt was about 2.4 MH/s.  If I understand correctly, x11 is about 3.5-4 x more, so my X11 hash rate should be somewhere around 9-10 MH/s?  What should I set the "d=???" to in my password?  Or can/should I just specify any password, and let it be handled automatically?

Many thanks!

Sorry, forgot to make a post here.  It was disabled on the restarts yesterday while working on some tweaks, should be re-enabled soon.


This is correct, however X11 only shows in the header if you have enabled it on the opt-in page.  Hopefully I'll get the stuff done to bring it 100% online (wihtout that page) today   And this post is correct, vsLTC is what you can use to compare which has been most profitable (the header is over the last 24hrs).

If you are asking about waffle's options you can see it on the front page - or any page:

scrypt   Hashrate: 19.01 GH/s   Mining: worldcoin   vsLTC: 114%
nscrypt   Hashrate: 477.14 MH/s   Mining: vertcoin   vsLTC: 138%
x11   Hashrate: 8.83 GH/s   Mining: darkcoin   vsLTC: 154%

Waffle doesn't offer X13 yet. The vsLTC number is what you can compare between algorithms.

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

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.

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

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?
