Hello,
I try to mine this coin , but all shares are rejected.
I have this 2x R9 280x-3GB , Ram 4 GB, OS W7-64bit, lates GPU drivers and using yac miner with config generated there http://ultracoin.net/configgen_raw.html
I try both config. and still only rejected share, NO HW eror.
I also mining UTC on this PC ,have no HW eror and rejected shares is low.
Can someone help help with this ?
I know my english is bad .. sorry for that , I am trying improve it Cheesy

A clean installation might help, especially if you have had your 750 ti's running on that computer. Nvidia drivers are notorious for system sabotage of AMD drivers.

I had all rejects until switching pools.

Another point that I have noted is that Sapphire Trixx will cause plenty of errors with Yacminer. I adjust as needed and then close before mining. I don't know if other overclocking programs have the same effect.

Try with older drivers(13.12).

This. very much this. If the config from the ultracoin site launches on your card, you will not get HW errors unless you're using drivers beyond 13.12.

Best GPU for the money for mining YAC is still the R7 240 4GB sapphire card. $70 card nets 365 -370 Hash/sec, and works perfectly fine with 1x risers.

As for how much one is making in a day, right now is _not_ a good time to determine that - the difficulty is still adjusting to the new network hashrate and hasn't hit its equilibrium value yet - look for it to hit ~90-100.

I think I need do full clean installation after change from R9 280x to R7 240 4Gb (sapphire)

My system is win 7 64

Drivers need change to 13.12 this is clear.

Some more questions

Yacminer and ultracoinminer (latest versions of course):

Do these need SDK also? And if need, what version exactly.
(previoussly in R9 280x rigs for N11 coins I have used SDK 2.8 with 3.7.2 "Kalroth's" CGminer )

If there is small rig's with 4x R7 240 4Gb what is recommended system memory. 8G still enough for YAC?

Are there any problems with x1 risers and how much these loose hashing power.
(With Nvidia 750Ti's I have big problems with 1x risers)

That did the trick. Thanx. I had to bump up the buffer from 3480 to 3560 for my 4GB 240. Other than that, there seems to be a significant lag in the console.

Here you can generate parameters for every card. No guarantees they will get the maximum out of your graphics card. For me they seem to work well.

http://ultracoin.net/configgen_raw.html

This doesn't even start on my system (Windows 7 64bit).

And this is my driver version info:

Driver Packaging Version 13.251-131206a-166389C-ATI
Catalyst Version 13.12

From amd's release notes, this fits version 13.12.

would you mind sharing your parameters?

It hasn't worked at all for me. I tried for three days to get my cards to mine again, with 100% hardware errors. I've tried EVERY reasonable config there is to no avail. Trust me. I'm stubborn. Something is very wrong.

Cuda cores even the ones in kepler gpus are overall better than amd stream processors if we can compare them so simple

740 might be slow...since it probably uses older chips and not maxwell.

It looks that N16 is somehow difficult to my R9 280x rig's))

Those have only got 3GB of memory and a ton of shaders - NF16 is not going to be your friend, but everyone is in the same boat, so it's all going to be relative.

Yes, it was experimental "try and look" with these.
I use 750Ti's for YAC and these R9 280X room heaters for UTC )

But how is R7 240 4G for YAC? any opinions? (and how much affect if use x1 risers)

What kind of (not very expesive) GPU's are now reasonable ok with YAC- Any opinions?

What is going on in http://yac.coinmine.pl

----------------------------------
..........Own...............Pool
Valid .......4.................58
Invalid......0................3,222
Efficiency..100.00%......1.76%
----------------------------------

This ihave been typical situation after change to N16

Perhaps some miners have forget change miners settings.
Nearly all (~98%) hashing power go to garbage.

I believe this happens every NFactor change - the difficulty takes several days to adjust to the new network hash power, but the pool simply sees that the network and pool are not finding blocks nearly as quick as it should and it translates that to poor efficiency.

I have nearly allways zero invalid and my efficiency is typically nearly 100%. (and whole pool effiency something like 2-3%)
If I adjust my miner wrong it start rise my invalids. (Nvidia looks more easy to adjust)

Yesterday I try with 4x Sapphire Toxic R9 280x (1x risers!) rig with yacminer. (I have not yet find how to adjust it due to lack of time for it). It produce lot of invalid. Hash rate in yacminer looks nearly ok but very very rare accepted shares, nearly all works go to garbage. (and this time also in pool my invalids and so also efficiency looks very very bad. So I turn these rigs back to UTC and there these works ok. It looks that N16 is somehow difficult to my R9 280x rig's))

Also CPU mining works now well with N16 (but of course only around 0.140-0.170 khash/s 4core 8 thread i7)
