The coin works fine in every setting I tested it. The only way I can explain you getting that error would be running a client of Photon that was from the initial release , before the code was modified for merged mining.
Also to address the post above where I questioned about how you are showing an intensity of 16 on a miner that to my knowledge does not go up that high the member states you built it yourself. OK , most people who are skilled at the level to compile cg miner would not need help setting it up to mine.
And yes I did post this 7 months ago
https://cryptocointalk.com/topic/1446-if-you-want-to-mine-blake-coin-with-a-gpu-here-is-some-information/I was solo mining and the build of miner for solo mining allows intensity up to 20 , so you are correct in stating that I posted settings for mining Blake 256 that allow an intensity of 20.
The miner I have for the merged pools (that I think is the same one everyone has /please correct me if I am wrong)
goes to 14 max.
I wanted to clairify this.
Also again I think there are ways to optimize the .cl file to get higher hash rates. I have not figured them out yet.
If I was solo mining (which I would not do when I can merge mine 5 coins at the same time) I would certainly recommend the builds of reaper with my settings (for a 7970) over cg miner, not only did it give slightly higher hash rates, i did a lot of testing and it seemed to solve more blocks.
I posted this in October when the Blake Coin project was very new and I was not involved with it at the time.
If it was not for the great work of those who optimized blake 256 for open cl most of us would be using cpu's.....
Show some respect for them.
