[ANN] [ASIC-RESISTANT] UltraCoin (UTC) - Ultrafast 6 second transactions!!

[Wirly]

Guys, trust me, use yacminer 3.5...it's way more intuitive to just set a lookup-gap value and a buffer-size one and then work on tuning -R (rawintensity). Should be using multiples of the worksize and that's about it.

I tried but I can't make it work. Have you got a config for a 7950?

Albert I sent you a pm

I was checking the orphan percentage at ultra2 and it was 40% in the last 24hours, 22.5% in the last 7 days.
So I'm leaving ultracoin for now, hope it will fix soon than I'll be back.

Me too, i mined for the past 8 hours with 400-450 kh/s and only got 31 UTC because of the Orphans, i'm back to VTC but at least i did some experience with yacminer.
Maybe if the orphan's are gone i will come back.

Two R9 270x, 28kh/s, No H/W

--lookup-gap 4 --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -I 16,16 -w 128 --thread-concurrency 40960 -g 1 --gpu-powertune 20 --temp-cutoff 90 --temp-overheat 85 --queue 0 --no-submit-stale --scan-time 1

Glad you got it working but I'm not going from 93kh/s on the last n factor to 28kh/s on this one. I'm going somewhere else until someone can find settings that will produce at least 38-40 kh/s with no HW errors. I tried for 5 hours to no avail.

lol keep daydreaming...

Try this, download yacminer 3.5 and use the following settings:

--scrypt-chacha --nfmin 4 --nfmax 30 --starttime 1388361600 --no-submit-stale --expiry 10 --scan-time 1 --queue 0 --gpu-engine 1120 --gpu-memclock 1200 --gpu-fan 0-100 --temp-target 75 --temp-cutoff 100 --temp-overheat 90 --auto-gpu --auto-fan --rawintensity 5120 --buffer-size 1698 -g 1 -w 256 --lookup-gap 4

no HW

That is a great setting for 7950. if you turn the gpu-engine down to 1040 and mem to 1250 you will get 50kh/s but big drop in power consumption

[kosaet]

Guys, any config for r9 280x ? I still got HW

[xen0s]

Guys, any config for r9 280x ? I still got HW

I got 60kh with yacminer and no hw, but its hard to reach if you have more than 1 card
need some woodoo magic, deleting binaries, etc

Thanks for the settings but since I'm not familiar with yacminer I must be doing something wrong because I can't get it to start.

[batty634]

Thanks to everyone for the yacminer tips. Got it nicely hashing along now on two of my rigs. I had the same issue as others with 4 x 280x, needed to drop the buffer to 1760 and drop R until no hardware errors. Now the rig is running @ 200 kh/s

Exactly profitability estimates are junk on calculators right now because
1) Poor cgminer settings
2) The Ultra Coin network is a pile of doge poo might as well just shut all the other pools down and have ultra nitro and be done with it.


Best thing to do for this problem atm which would make everyone happy

Step 1
Nitro cuts fees to 0.5%
Step 2
Proxy all the other pools to mine on Nitro and funnel all the workers from other pools into nitro

Like this everyone can just mine wherever they want and not have to deal with a 50% orphaned block rate.

This will eliminate all the orphans and unify the network.

Its obvious at this point that UTC will never be a decentralized coin, so might as well embrace it and atleast if you are going to have one big pool , set it up so that its a level playing field.

So you have 4 x 280X's running at 50KHs per with 8GB RAM? May I have your final settings? Thanks!

Above for R9 270 gigabyte generating 38 kh/s on bamt yacminer, but WU is too low around 22. It is much more important to see your WU output as well not only kh/s. Thanks for config (Cпacибo зa кoнфиг).

Hi xweb.

WHat's with this on the first page?

http://www.ximages.net/images/94823170413860868540.gif

Any way around it?

Here you go, I was the first to post it which now everyone is using AFAIK.

280x(7970) @ 60Kh/s

55Kh/s at 1025/1500 @ 1.075v
60Kh/s at 1110/1500 @ 1.150v

1. Use latest YACMiner. https://github.com/Thirtybird/YACMiner/releases
2. Use following core settings: (Add other settings, more pools as needed)

yacminer.exe --scrypt-chacha -o <pool> -u <id.worker> -p <password> -R 8000 -g 1 -w 128 --buffer-size 2656 --lookup-gap 3 --temp-cutoff 85 --nfmin 4 --nfmax 30 --starttime 1388361600

Note: This may ONLY work on a PC with 8GB "physical" RAM regardless of VM size. (I tried up to 32GB)
If you have 4GB RAM machine and it fails, try using a lower buffer-size of 1760 and -R of 6144 or 5888.
As the rawintensity is lower, you will end up with a lower hash rate of about 45Kh/s unfortunately.

Some tutorial on YACMiner for everyone

Update: Config Generator = http://www.ultracoin.net/configgen_raw.html

YACMiner allows finer control of the intensity value so you can squeeze every bit of its hash rate which ultracoin-miner cannot.

--buffer-size cannot go over the size of your video card's RAM amount. It's usually around 10% less value.
-R is basically Intensity equivalent in cgminer. YACMiner allows for more granular in-between Intensity values. (e.g. 12 = 4096 & 13 = 8192)

Goal is to try and squeeze in as many threads (intensity) in to the amount of buffer without it going into dynamic memory.
So first try to find the largest max buffer size your system will work with. Go up in increments of 128 until it fails to start.
Depending on system RAM size, you may need to start as low as 50% of your single video card's RAM amount. (e.g. 3GB video card  1536)
Once you know the max buffer size that works, set it as that and leave it alone.

Now just adjust the -R value in increments of 128. Good to start from something low such as 4096 and work your way up.
If you set it too high, you will either get HW errors and much less WU or it'll just fail/lockup/crash etc. Dial it down if so.

Lastly, check your WU over at least 15-20minutes. Clocking higher might givss higher hash rate but WU might not go up.
You might end up using 5-10% more electricity but end up not actually doing any more real work. So keep an eye on WU.

Whats the power consumption like with the change in the n factor ? Is it roughly the same amount of UTC expect a day for slightly less power ?

Also, I find that I have 5 GPUs, one of them seems to only do 13kh/s on a 5x 7950 setup (the rest runs 40kh/s)... Any ideas ? Is it because I only have 8GB of RAM ?

Power consumption for me is about about 5% less than before. Not a big difference.
Amount you can mine has nothing to do with N-factor. It's about network difficulty.
Not 100% sure about your 5th card. Try using YACMiner and try tweaking -R value.

Jakiman's post nails it. My rig has one card @40KHs which is the only gigabyte , the other 3 cards are asus dc2t @ 55KHs. Don't know why one card needs to be dropped in buffer and -r, although I am very happy with the overall rate.

for now

Any plans what u gonna do?
My suggestion to run only p2pool is that good?

Is ultra1 also getting orphans or not?
