Thanks for your help, I appreciate it much! But none of your configs help. Even with LG 3 it ends with error -61 (clCreateBuffer), so I had to lower TC to 8192 and that keeps hashrate around 75 khash.

I heard this may by RAM related. How much RAM do you have and which OS are you using?

Sorry guys, I still have problem with my GIGABYTE GV-R928XOC-3GD. I have three of these, each in separate machine.
With one, I am getting 130 khash/s (and I am happy with it). The other two have ~70 khash/s and I can not get any more out of them (I start getting HW errors). Do you have any clue what may be the problem?

Thanks in advance!

One additional question. How much are you getting off your cards? I have Gigabyte R9 280X (GIGABYTE GV-R928XOC-3GD) and I am getting about 130 khash/s.
(I know it is beacuse N-factor, just want to be sure, I have it fine-tuned, so I am getting as much as I can : )

I think, I figured it out. I was missing space before --scrypt-jane
Ouch, lame! 

Can somebody help me with my conf? I am pretty desperate, after N-factor change I am only getting rejects and cant help myself, even after conf tuning

I am using Gigabyte R9 280X (GIGABYTE GV-R928XOC-3GD)

here is my config:

ultracoinminer --scrypt -o stratum+tcp://ultra.leetpools.com:3333 -u XXX -p XXX --lookup-gap 2 --thread-concurrency 16384 -g 1 -I 13 -w 64 --gpu-powertune -20 --auto-fan --temp-target 72 --temp-overheat 85 --temp-cutoff 90 --gpu-memclock 1500 --gpu-engine 1050--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -E 1 -s 1 -Q 0

I think, I would like to create some print on my own, will consult it with you before printing.
Oh yes and I can donate one shirt for every 10 sold as an giveaway, for sure!

Hi, I am a huge UTC fan watching this thread almost from start. I would like to give other fans an opportunity to spend their UTC in real world. I would like to print and send UTC - related t-shirts and send them around the world.

For printing I use only finest 180g shirts and quality screen-print eco inks that lasts as long as the shirt lasts.
I think, that price for t-shirt including postage within Europe can be 250 UTC, and within rest of the world 275 UTC

It may help to spread the word and will allow you to spend your UTC in real world

So, what do you think?
