Ok, i'm a total newbie in mining
After 1 day of setting-up, i was able to start cgminer with my radeon HD6990 and succesfully mine some dogecoins for the lulz
Now i'm mining lottocoins, but this dosen't matter... only to say that i'm scryptmining.
My actual speed is about 260 kh/sec @ intensity 12, if i set intensity to 3 i'm getting a massive amount of HW errors and hashrate on the pool go down (but still seems high on the miner).
Any suggestion? Should I be happy @ 260 or i can get more?
