I am solo mining so fast, the problem is on the pool.
I tried the pool like 1 hour, I didn't find any block.
Then I switched to solo and now finding a lot of blocks.
C'mon, try it !!!
No rejecteds for me... just "New block detected on network" and several seconds/minutes: Found block.
Good luck !
Dang, what's your Kh/s?
Just 700 kh/s (only 1 gpu)
But I found 6 blocks in 1 hour

I am following the diff, perhaps when it goes to 0.1 or so I will switch to pool again hehe
