Super Zombie Mode requires lolminer and 4gb gpu.  You can run 1 or 2 (a few very large cpus can run 3 or more) 4gb gpus at nearly full speed.  You must put the card physically in the long slots.  1st gpu in slot 0 closest the cpu.  The second if your board support into another full slot,  The trick works but using the pcie lanes to supplement the vram on gpu with system ram.  You need x16 pcie lanes to get full speed with x8 providing about 50% of the SZM vs ZM.  So a 570 about 26+mhs, 560 14.5mhs....at SZM.

So if you had say a 3 card riig (580-8 / 570-4 / 560-4)..and it has 2 long slots...and you have 24 pcie lanes becuase of the cpu you are running you would put 570-4 in slot 0 / 560-4 in slot 1 / 580-8 on riser to x1 slot...and could see 26/14/30mhs = 70mhs.

Which beats the hell out of doing all x1 risers and only seeing 48mhs for all 3 cards (4gb cards would be in zm but not szm)

It will end but looks to be some weeks/months away.

There are no options to set in command line.  It will detect and tune all cards automatically.  Just set algo to eth.
