On this computer only I have to tap into one card and and Lower the intensity to be able to use this.... so I put -d 0,1,2 -i 16 and it lowers all cards hashrates... it should be -d 0,1,2 -i 0,16,0 but that doesn't work. I'm tapping into card 1 or device 1. On all other algo's setting intensity to each card works like this -d 0,1,2 -i 0,16,0 or like this -d 0,1,2 -i 0,14,0 and works great. Setting is dependent on the algo.
I use 8gb memory on all my 6card rigs. And you should add 8-16 gb of virtual memory as well. High intensity and 6 cards require alot of system memory. When you add virtual memory remember to reeboot to get the effect. Windows 10 is no good. Use windows 8.1 or windows 7. I have run for weeks without a reeboot or crash in the sp-mod private, but I use a failover script/ miner control software as well.
