Just jumping back into Ultra Coin from original launch.

Using a GTX 970 with just auto clock gets me 4.79-4.85 kh/s. Does that sound about right for anyone else using the card?

I'm getting 6-7kh per 970. Try adjusting the look up gap to 2.

I tried to adjust the look up gap but it kicks the driver and shuts down. I have it auto tuning and t picks the -l t63x1.

The UTC multipool will be moving to a faster server so that we can pile more wallets on it. If you are currently using it you will need to change your stratum from stratum.tumblingblock.com to multi.tumblingblock.com. That change can be done now. I will be doing the actual move and export of its state 10/6 at 7pm PST. The stratum will be down for about an hour and it should be back up fully once the DNS change takes effect.

is time to buy UTC!! in one week conferincei n Las Vegas...and i thinks price go crazy like 5-10X UP Cool

I can not agree more with you !

Buy now when it is still low and smile later..... or cry when it rises 5-10x up and you are to late !

I can not wait to see how UTC will rise the next weeks after taking part at Hashers United Conference in Las Vegas ....

If you are having difficulty mining Ultracoin directly, you can always try the multi-pool: multi.tumblingblock.com

Otherwise, check out the mining configurator to help you find the best settings per card, and tweak from there: http://cfg.ultracoin.net/

@doctorbobbo, have you tried the CPU miner that is built into the UTC client wallet?

I tried, could not make it work. It asked for the minerd in the same directory as the QT, so I took the exe from the ultracoin-miner download that matches my CPU and put it in that directory and renamed it "minerd".

The miner can't start, I think it only mines pool.ultracoin.com, if I put another pool there it prefixes the URL with http:// which is wrong for my pool which is stratum (ultracioners.info). I can not try pool.ultracoin.com, as I have no login and it is closed for new accounts due to the high hashrate.

I don't expect it to be any different from running the same exe of the command line though, which is exactly what I did before to get 0.9 Kh/s.

Would be interesting though to see if the other pool has higher efficiency.

Got this to work now with the settings for Yac miner in the post above. Works fine, I get around 4.9 Kh/s / card in the miner, no HW. In the pool I get at total of 7.5 Kh/s for two R9 290x after a few hour mining. I am a little concerned that there is a 25% difference, I don't know if that is real difference or just how the pool measures. If it is real it's a rather inefficient pool compared to other pools for other coins. What are you experiencing in this regard?

I solved the cpu miner problem as well, by setting the N-factor and starttime on the command line. This gives me around 0.9 Kh/s in the pool with 15 threads, dual eight core xeon @ 3.1 GHz. This is to low to be worth it, I get six fold higher yield by mining cryptonight and selling those for UTC. With GPUs it is thigh which is the most profitable, I'll mine for 48h and evaluate.

Thanks for all help!

True I used N12, did think it defaulted to the current N-factor automatically. Where can I get the current N-factor, published anywhere?

My CPU miner sets it 10 16 automatically, why? Do you know if I can set that explicitly on minerd-yac?

This machine has 64 Gb of RAM, can that be used to increase hashrate? Which settings?

Thanks for the help, will try these settings now!

You can check current nfactor here: http://ultracoin.net/nfactor.html
As for other questions I have no idea, but I think more RAM gives nothing, although the more NVRAM your GPU has the more RAM you should have. 64 GB is enough or even too much Wink

Also what hashrate can I expect with the current N-factor? I have two r9 290x (Saphire trixx). at the moment I am getting 18 Kh/s on each, while my CPU (intel xeon) givs ~25 hashes/s / thread.

Something is wrong. R9 290x is not over 4 times faster than Sapphire toxic R9 280x.

With "conservative" settings for reliability, one R9 280x give around 4.2-4.5 khash/s.
With some aggressive settings it can pump some small amount higher depending many things.
R9 290x can not be 4x faster. So, my opinion is that something is wrong with your settings if it continuoysly show 18kh/s for one R9 290x.

I would also guess that @ 18kh/s he's getting massive HW errors. He needs to post a screenshot of his cmd window and show what settings are being used.

You are perfectly right. I restarted the machine and now it shows plenty of HW, don't know why it didn't before. My settings are:

yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 3 --buffer-size 3532 -R 10496 -o stratum+tcp://ultracoiners.info:3333 -u <> -p <> --nfmin 4 --nfmax 30 --starttime 1388361600

which is exactly what I got from the config website in the OP. Any idea where to start for really conservative settings for R9 290x?

I actually never used Yacminer before, and I started first with ultracoinminer with the settings from the config website. This crashed my AMD display driver (which "recovered successfully") but then it only showed 0.0 Kh/s, I tried to tweak the settings but it never helped, so I gave up and switched to Yacminer. Actually thought I had it working, but no joy .....

The settings I had for ultraminer was:

ultracoinminer --scrypt-jane --worksize 128 -g 1 --lookup-gap 3 --thread-concurrency 98400 -I 13 -o stratum+tcp://ultracoiners.info:4444 -u <> -p <> --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600

Any help highly appreciated!

I used the config generator for a 290x with 4GB of ram and here is what I got for yacminer. Very different from yours.

yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 3532 -R 7040 -o stratum+tcp://: -u -p --nfmin 4 --nfmax 30 --starttime 1388361600

If your card has 6GB of ram then it should be --lookup-gap 7 --buffer-size 5416 -R 9344

How much DRAM does your mobo have? It plays a big part with high N-factors.

He have used N12 Wink

Imho, this -R 10496 is far too high for N14 and specially if also lookup gap is only 3, your buffer is far too small for this massive amount.

N14 means 8M mem need for one....

Try R under 1000 and start then increase it for find optimum. (do not look only miner display and gross hashrate, look also how pool "think" about your hashing)
If you use higher lookup gap then of course raw intensity (-R) can be higher.

I do not know if lookup gap 3 is optimum with your system. But if these are used your -R is really lot of too high.

Of course my thinking here may be bullshit because it is long time I have adjusted amd radeon mining.

Btw
From http://www.ultracoin.net/configgen_raw.html for R9 290x 4Gb mem and N14
-------------------------
yacminer --scrypt-chacha --worksize 128 -g 1 --lookup-gap 8 --buffer-size 3532 -R 7040 -o stratum+tcp://: -u -p --nfmin 4 --nfmax 30 --starttime 1388361600
-------------------------
Then example If yo drop lookup gap half then you need also drop -R

I believe you have accidentally used N12 when you get these values!

With a variety of different packages to suit each businesses need, companies can now connect to the Ultra economy easier than ever before. The problem with many crypto-currencies is the inability to connect users to businesses, thus, coins are never spent and the volume never grows. With Use Ultracoin, finding businesses that accept Ultracoin has never been easier, whether it is an eCommerce site over the web, or a brick and mortar location in the city.

Businesses that have been lacking a venue to reach the crypto-currency using public now have one with Ultracoin, setting up a listing is extremely easy and highly customizable to you companies needs. Custom sliders on the main page carousel are also available for businesses looking for extra "in your face" exposure. Users can find the businesses they are looking by choosing the category they wish to explore, or view the recent listings for new additions.

Turn your computer power into real world goods and services using Ultracoin!
