Hi

Are these hash rates from pool end or from miner?
Thanks!

I made one rig with one gpu  Grin (two years break). Waiting more information (GT710) and then I am going to buy more gpu's. Pool is working and no problems at all.
Seems that low end cards are mining quite good.  Cheesy

Scrypt-jane algorithm is really undervalued.

Thanks for the info. Most of these things I already knew, I've been mining (heavily) for past 5 years.

Could you post some reference hashrate values for cards you own? Scrypt Jane algorithm is far away from the spotlight. With Claymore miner for newer algorithms you can't influence hashrate with some settings as it was the case with older algorithms. And without some reference values it's hard to say if everything is working as expected.

Edit: room for tweaking is very limited. I get around 550 H/s with -I 8 and 1.05 KH/s with -I 9. Still, with -I 9 some of the cards occassionaly give HW.

Rig with 6 x 270 draws around 330W from the wall, much less than 580W while mining Zcash.

This seems to be very strange algorithm. Type of card somehow doesn't affect hashrate. My 280X and 270 cards give same hashrate with same intensity settings. That explains why that tiny GT720 with -I 9 also gives 1.1 KHs.

UTC hash rates for hardware in my rigs (@ Nf = 14)
R9 270X 4GB: 2.23 Kh/s x3 ( -I 9 cgminer-3.7.3-kalroth-sj0.03)
HD 7950 3GB: 1.15 Kh/s x2 (-I 8 cgminer-3.7.3-kalroth-sj0.03)
R7 240 4GB: 0.837 Kh/s x6 (-I 9 cgminer-3.7.3-kalroth-sj0.03)
GTX 750 Ti 2GB: 2.20 Kh/s x1 ( t64x1 cudaminer-2014-02-28)
GT 740 1GB: 1.30 Kh/s x1 (k4x25 cudaminer-2014-02-28)
GT 720 1GB: 1.13 Kh/s x4 (t17x3 -or- t26x2 cudaminer-2014-02-28)

Also investigating viability of the GT710, as it reportedly hashes 50% better than the GT720 @ the same ~19W TDP.  The card is laughable for games/graphics performance, but has potential for UTC @ Nf=14.  If my test GT710 holds up, I will be creating some super-cheap 5x rigs.

 

These values are direct, per card, from the miners.  Pool rates tend to vary, but average about the same.

Will update when I get a GT710.  This may not be for awhile, though.  If someone else gets one (they are everywhere, and are not especially expensive), use the Cudaminer version referenced above.  For first run, let it autotune before setting permanent config, then experiment from there. Post your bat info (minus acct. info).

Sorry..it did not work. I did download the CGminer again from the link you provided. Thanks in advance.

This is the text in the .bat for one of my pool workers (R9 270x):

cgminer --scrypt-jane -g 2 --worksize 256 -I 9 --thread-concurrency 16384 -o stratum+tcp://utc14.yacoin.club:3413 -u [change to your worker name] -p [change to your password] --sj-nfmin 14 --sj-nfmax 14 --no-submit-stale

* Note:  This .bat text specifies "--scrypt-jane" and does not use  --sj-time 1446256800.  This works. Try it.




I tried these settings on two of my R9 270 rigs, and both froze within few seconds. I tried -I 5 on seconda rig, but it still froze.

Edit: mining started when I changed to -g 1, but I only get around 550 H/s with R9 270. That seems quite low compared to 1.1 KHs with GT 720 you mentioned.

Performance across brands can vary.  R9 270 is not the same as R9 270X.  2gb  vs. 4gb can have an impact.  Many variables.  I have some HD 7950s that under-perform on higher settings.  Yes, not entirely the same case, but it gives me some ideas. 

First, try a very basic .bat to check what your baseline is:

     cgminer --scrypt-jane -o stratum+tcp://utc14.yacoin.club:3413 -u [change to your worker name] -p [change to your password] --sj-nfmin 14 --sj-nfmax 14 --no-submit-stale


Then try this (just add -I setting) to see if things improve:

     cgminer --scrypt-jane -I 9 -o stratum+tcp://utc14.yacoin.club:3413 -u [change to your worker name] -p [change to your password] --sj-nfmin 14 --sj-nfmax 14 --no-submit-stale

Finally, try this (settings about 50% of the original .bat info posted):

     cgminer --scrypt-jane -g 1 --worksize 128 -I 9 --thread-concurrency 8192 -o stratum+tcp://utc14.yacoin.club:3413 -u [change to your worker name] -p [change to your password] --sj-nfmin 14 --sj-nfmax  14 --no-submit-stale

A couple of things to really pay attention to:  Intensity (-I) and  --thread-concurrency are great for augmenting hash performance - to a point.  Too high will greatly slow down, or lock up your whole rig.  -I too high will also generate hardware (HW:) errors.  Lots of HW is wasted hash - you are just heating the room, not solving blocks.

Every rig is different.  Experiment, and use whatever gives you the optimal result.

Just an observation RE some efficient hardware:

The GeForce GT 720 will hash UTC @ ~ 1.1 kh/s, drawing 19W TDP. 

In your .bat, use hardware config (-l) t17x3.

These are selling for around $30 USD on ebay.   Great for an inexpensive UTC starter rig, or if power costs are a concern. 

*This info is for UTC/scrypt-jane/scrypt-chacha coins only.  These cards will fry if you use them to mine a coin with a more intensive algo.

Hi.  I use cgminer-3.7.3-kalroth-sj0.03, and it works very well with HD7950s. 

Here's a link to download:

http://cryptomining-blog.com/wp-content/download/cgminer-3.7.3-kalroth.rar

My .bat for 7950s looks like this:

cgminer --scrypt-jane -o stratum+tcp://utc14.yacoin.club:3413 -u YOUR USERNAME -p PASSWORD --sj-nfmin 14 --sj-nfmax 14 --no-submit-stale

Your Intensity values and --thread-concurrency are up to you.  Values that I use are not for stock cards.  My 7950s have been nearly toasted by continuous mining, so they are set very low, and require a lot of TLC.  You can get good hash from R7 240 cards, too, if you can score some cheap.

Cheers & good luck.
