The main benefit of the BTC MBs is the ability to supply 75W to 1x slots which are normallly limited to 15-25W, which makes the use of unpowered risers possible.
All the motherboards can provide 75W thru the 1x slots, it's by specifications. The rest of the pins do not provide any power. The difference is that the BTC MB can provide 75W to ALL the slots together. I wouldn't ever pull 75w through the tiny little traces on a motherboard to all the slots at the same time, that's just a recipe for disaster, regardless of having a extra molex connector or two supplying juice. As I said, my 2 rigs are runing perfectly, 6x960 and Pro BTC. Even OC'd. Now is 3 months already. And cheap cheap risers.

Crazy question - could i run (2) algos on the same rig in (2) separate instances. For example - (1) instance running X11 and (1) instance running (Skein2) on the same cards? What are the draw backs if any? I checked power consumption and there doesn't seem to be a change in power draw. Just wondering if I can break my rig that way? Thanks - pokeytex

Can't break your rigs that way but likely the driver will crash sooner or later. Or one algo will probably dominate the other so the hashrate won't be equal. Depending on what you want to achieve you might be better off dedicating a couple of cards to one algo and the rest of them to another. Or you could just use a batch file which switches between the two algos periodically or as a failover.

Interesting thought. It won't break anything, it's just like running multiple processes on a CPU. But I don't think it will work well. Most processors perform better with fewer processes with better cache performance and less task switching overhead. Vector (SIMD) processors like cuda are even more optimized for doing the same thing over and over. What you are suggesting would be suitable in a hyperthreaded environment where two threads share a common set of execution resources. As long as the two threads require different execution units they can run simultaneously. Unfortunately mining algos use almost exclusively integer arithmetic so the combined peformance of the two threads would be the equivalent of one. It might be worth an experiment to see what the combined performance is. You can always run different instances on different cards if you want to mine two algos at the same time.

YES YOU COULD-- I always ran 2 instances of CudaMiner on scrypt. The rigs would get slightly better total hash rate, and if one instance crashed, the other would go from 1/2 hashrate to full hash rate. With mixed algos, you'ld be running separate threads through the cards. You could run 1/2 cards on one algo, and 1/2 on the other algo with "-a x11 -d 0,1,2" and "-a quark -d 3,4,5" on separate instances. You could run two instances with separate algos on all cards. The drawback is probably that you loose efficiency, and the cards would run hotter, with the overall hashrates being lower. Have I done it? No, but you could try it and report. I don't think your rigs will break. --scryptr

Can't break your rigs that way but likely the driver will crash sooner or later. Or one algo will probably dominate the other so the hashrate won't be equal. I've done it unintentionally, never saw any crashes but never let it run for any length of time or measure performance.

Ok - well thank you all for the informative posts above. I did try it and as you said - the efficiency was divided in half. I did decide to separate into (2) instances with the -d parameter and designated half of the cards to one algo and the other half to another. Thank you all for the info - poketex

I don't think your rigs will break. --scryptr Pretty much... running the same algo usually it just splits the hashrate between the two instances. If you're running two different algos, the cards are probably utilized differently and you'll end up with a weird bottlneck somewhere that causes a loss of efficiency for both algos.

does anyone known what this is extranonce.subscribe and how to get rid of it
You can run ccminer with the -e switch to turn it off. -e I don't know what that is. sp do you have the latest readme file on ccminer ? Ps contributions coming soon. Got my new rig working again with 2 750ti....2 980ti . EDIT: Electrical power line went down yesterday and burn out my new rig......... f#@&............ it will have to wait.

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks
