Thanks. Nice. Good fast work.

Do anybody know what is going on in

Pool stat show normal hashing all time but balances stay zero.

On the pool side no any information about any problems. It have worked perfect months and now it still looks all including me hashing normally but no coins.

Why this disinformation?



Here in the 1. message (this is official information)


•Total coins: 100,000,000
•Premine: 2% (1.6% IPO / 0.3% DEV / 0.1% REWARDS)
•Block time target: 60 seconds
•Block reward: 30, halving at 4,000,000 blocks
•Difficulty retarget over 10 blocks (Max 8% Up, 16% Down)
•Mined block confirmation: 50
•Transaction confirmation: 5
•NFactor Integration
•Port: 44100
•Rpc port: 44101

Exactly. Also it is today  easy for mine.
And if people feel he really need UTC for some reason, he can buy.  All time there is mined more UTC's  than there is buyers. Why set this kind of Nfactor timetable and  using chacha algo  and after then try generate easymine tools, what is logic?

Also there is so much HW and software (OS versions etc things, including GPU versions and there also different manufacture lots and possible cnahges in they FW's etc)  combinations that one click miner what works in all Computers/rigs  is nice dream but I suspect  it never happend. But of course some kind of one click miner is possible for limited amount of HW/SW combinations. I'm also not sure do this mean for AMD or Nvidia or both.

Perhaps if want support more "easyminers" it is more easy way to teach some Basic Fundamentals and principles to peoples about mining and configurations and so on, how settings related each others and what they really mean. To peoples who have very different levels of skills, experience and knowledge and also to lazy peoples who want all just now as free lounge or even so that some people serve directly with spoon to mouth. If people want salary, it need work. There is not real free lounges.

It is good to realize that Nvidia needs lot of more trafic between main board (chipset, CPU, memory)  and GPU than AMD.
Perhaps bottle neck come there just as one possible suspect about why.

What is HW combination what can really handle 6x GPU using maximal/enough  datastream speed for all these.

AMD (O. CL) do not care example if use 1x risers (due to much less needed data trafic thru PCI-E). But Nvidia (Cuda) start suffer even in fastest HW system if use 1x communication with PCI-E.  What HW (it need also look how CPU itself is related to this)  is designed for handle with real full speed 6x Nvidia GPU data trafic through PCI-E.  And still we are with  easy Nfactor 14.

Also operating system may affect due to things how they share resources.

exellent!

...and also it looks that our all works have been safe without any loose.

What is going on in yac.coinmine.pl  !!

No any information... and miners are hashing just air?


...and so on... long time... and blocks statistics are just straight line...

No. It looks like UTC relative hashing power  is well over MYR-Groestl.

With Myriad-Groestl  just one 750Ti may give over 11Mhash/s and one R9 280x something perhaps between >10 - <20Mhash/s
(ref: http://myriad.theblockexplorer.com/help.php  )

My just one tiny 4x R9 280x rig give around 17kHash/s(gross) with UTC  and 4x750Ti rigs some amount less.


And more "fun". Quite soon (2015-01-22) UTC  N factor rise from 14 to 15.

But yes, if someone have. say example well over 1200 x R9 280x farm he can try but still not at all easy.


Of course it is possible that some develop lab test with MYR they FPGA-ASIC hybrid machines what they try develop for many algoritms and for higher N factors.

Yes.

Example I'm mining with Sapphire R7 240 4Gb (these are perhaps best for YAC and other high N coins if think price, power and hashrate combination),
  
then also randomly I use Sapphire Toxic R9 280x  (but these are not at all optimal for YAC when N=16. And finding optimal settings is more or less difficult depending whole rig features, not only GPU)

Some help for settings can find here: http://www.ultracoin.net/configgen_raw.html
but note: some parameters are only for UTC and these need change/remove for YAC

Most settings, what you find easy, what peoples have shared around forums etc. -- look carefully what are date of these messages because many of these are totally obsolete due to change of N value.


and also of course I use Nvidia. Asus GTX750TI-OC-2GD5 what is good for YAC (and other high N coins)

Where?
I can see only just normal after UTC get "new life".

UTC Network hashrate chart
UTC Difficulty chart.

Then
@Namsbreh, @tc61

Independent of diff every day around 43200 UTC total (30s average block time and every block 15 UTC.) More miners one get less and vice versa. Just basic fundamentals. If you have alone 100% of netw hashrate you get these all. If you have 1% of network hashrate you get (average) 1% (432UTC)

If some day or hour this network total hashrate  is 1Mhash/s diff is set so that average block time is 30s what leads to 43200UTC/day. If some other time network hashrate is 10Mhash/s then diff is set so that agen same result, 30s average block time and 43200 UTC / day.  

But, of course if one have 10khash/s (network accepted hashrate) miner in first case he get average 1% of these 43200 coins (430 UTC) per day but in last case 0.1% of coins (43 UTC).
There is not any kind of secret mysterious things. Just basic math from very simply basic fundamentals.
(of course this is simplified, there is orphans, fees, variations and so on, so in short time result may be very different, but in long time average very close this simplification)

Very short time variations, just do not care. This is normal variation and is expected (just math)
Example if you now see 6Mhash/s network and after 5 minutes you may see 5Mhash/s  and quite soon you may see 7Mhash... do you think there is this amount jumping miners. No, it is (mostly) normal short time variation. Look longer time averages. (least hour or hours)

If your miner have quite low hashing speed, so that it may get under 1 pool difficult, least then use port 5555.  (European pool have also port 3334 what have variable diff but limited so that it do not drop  under 1. )

I have connected my some rig with yacminer what have around 17khash/s to port 3333.  I can not see problem in this case.  This kind of rig (one 17kh/s worker) get always over 1 pool difficulty and if I have understood right it is ok) Previously I run small tests with  small miner (1x and 2xR7 240 4Gb) and there was problem  because pool (port 3333) drops its pool diff under 1 soon after starting.


There is not good and enough deep explanation about this Yacminer problem what it is exactly. But least this I have seen that under pool difficulty 1 there is problem to count   accepted shares.

It is perhaps useful also look what information now or later can find from YAC coin  discussion because there problem is perhaps more wide due to much lover hashing speeds (due to N value 16)

Great news!

Just this kind of things show that UTC is now dominated by a very experienced, strong and wise dev team peoples.

I will plan to move my all workers asap to some of these official UTC pools.

utc.tumblingblock.com
utc2.tumblingblock.com
ultrablockparty.com   ( Europe, Amsterdam)

Nice days to buy from weak hands!
 

I have now some small miners(workers) running in UTC European pool . (as rapture333 tell there is some frontside things under work...  but this pool can use. )

UTC European pool Ultra Block Party



Now I have mined some short time  using

- port 3333 (cudaminer) mining  works well.
- port 3334 (Yacminer small miner what many times get  below 1 pool diff in full vardiff. In this port it do not get below 1 diff and it seems working well)


In Europe, ping time to this pool is much less than USA pools!   In long run it may give some advantage for European users.

I think it is also good to share hashing power more spread than just one pool. In small pool where pool hashing rate is low credit have more variation but average is same as long as all other things are ok.

It is also good to have  distributed geographically wider area.

Thank you. Exellent!


This is good:

Ultrablockparty.com/
port 3333  vardiff
port 3334  vardiff, minimum diff 1
port 5555  static diff 1



Yes, cudaminer do not have this problem.
I will make new test later after I have time for it.

Very short test with small <5kh/s test miner using yacminer. Overall it works but... With small miner it soon drops pool difficulty under 1 and yacminer is in troubles. Due to lack of time I did not test with more powerful yacminer rigs and cudaminer rigs.

Please add one port where is vardiff but limited so that there is minimum diff 1.

Great!



Lets hope European peoples find this pool useful soon. (later I will try some mining test)

For me in north EU: --- PING ultrablockparty.com  : icmp_seq=1 ttl=58 time=14.4 ms

Stop accept new accounts for http://ultracoinpool.info/  (I wonder why it have not been blocked time ago.)
If I remember right it was previously but it looks like continuously open for new miners. Why?

Ultracoinpool
                Gen.Est  // found
Last Hour         120 // 73
Last24Hours  2,880 // 1,639
Last 7 Days 20,160 // 12,625

Why this is problem. This is PoW/PoS coin and very difficult to see so bad 51% danger.

Also these all avalable three pools have quite long ping time from europe. I have 91-92ms to ultracoinpool.  94-96ms to ultracoiners and around same to tumblingblock.
Some peoples around of world may think that this is US only coin.  Not very good situation. 
 

Exellent work! Also it works quite fast.

Thank yoy "rapture333"!

Very good answer.  Least I'm very satisfied about your explanative answer.

Show must go on. UTC is too good for suffer this kind of any even temporary problems.
