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.

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. 

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.

Hello, regarding on ultracoin


For the ultracoin on the Waves platform, its another coin? or its the same coin as ultracoin itself which the supply is share within both waves blockchain and ultracoin chain itself?

Thanks

Purpose is an opportunity that can be drawn on if the community wishes to.

Android, iOS wallets, desktop lite wallets, tradeable on DEX to other currencies and FIAT  etc

I think there is no ultimate predetermined purpose - its just given to us by WAVES platform and its up to us to use it as we think is best.

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. 

Hello guys! Well I'm a little bit confused, what is the purpose of the UltraCoin Token? This project will be developed further or the Waves token? Thanks!

Thanks for "chipping-in" Chip254.

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.

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

You need to use cgminer-3.7.2-scrypt-jane https://www.nicehash.com/?p=news&id=41 with this parameters:
--sj-time 1446256800 --sj-nfmin 14 --sj-nfmax 14

Guys,
While mining this I am always getting rejected, low difficulty error. Why is that? I am mining here: http://utc14.yacoin.club. I am using CGminer 3.7.2

That would help a lot 

Note the LITE wallets coming soon for Win, Mac and Linux.

They won't require the blockchain download.

Problem With this coin is among other Things downloading the blockchain takes an eternity even if you download the zipfile.
It's gonna put most People off the coin.

Don't worry - I'm still here and Steven and I are working on Ultracoin in the background.

Hope to have the LITE wallets out soon.

Cheers - usukan

we shall wait eagerly for your coming back..so do not forget to come soon.as it will be possible for you...

ah - OK I see your problem now.  Its not my area of expertise at all.  Will need a pro miner to offer you advice here.

No, I did all necessary steps. It's just that miner doesn't recognize cards.

Update

Java.dev has been on holiday but is back to work on our wallets now.  That is - LITE version wallets for Windows, Mac and Linux.

Steven is coordinating with Java.dev so we hope to have some releases soon.
