I'm trying solo mining and I wonder which way is better: having 1 reaper instance with total Mh/s power or I can use 2 instance -I prefer this way cause of mixture of cards 5xxx with 7xxx in one system- without affecting my chances of solving faster the block.
Or it doesnt matter how many instances since I mine just 1 block at a time and all the solved work is passed locally on server.
I really cant wait for the fixes in the upcoming cgminer so i can switch, as im sick and tired of babysitting reaper, but it is the only way I can get very good hashrate on 5xxx and 7xxx.
you should really have 2 instances of reaper when using non-identical cards, reason being obvious and simple, they do not use the same configs, especially 5xxx and 7xxx. Using 2 instances has no negative effects. In fact, I use 2 instances on dual gpu cards.
And also, cgminer is unfortunately much more troublesome than reaper for scrypt, especially 7xxx. Thats unfortunate, because I feel miners are the bottleneck of 7970s (and perhaps 7xxx) and cgminer having trouble with scrypt and reaper being abandonware, I cant really forsee that bottleneck being lifted soon.
And before I get argued about for my claims, the reasons are : at intensity 13 being able to get better/similar results at intensity 20 suggests even when running full power/priority, a lesser strain achieves similar results ( do the math, when full "power" achieving the same as non-full suggests a bottleneck) and also the differential between shaders not correlating as much as other models. A couple other reasons.
I would have expected the cgminer with pool stratum leech for solomining to give result, not the half the khash weaker card.
