Wow! That's VERY impressive indeed! I have 4 x MSI R9 290 Gaming cards running
Win8.1x64 with tweaked settings from AfterBurner and I'm only getting ~12300 c/m
with the latest software from NaN. I'm still tackling the 2 thread thing myself and
currently run the -t 0,0,1,1,2,2,3,3 which doesn't get me much more c/m but severely
increases my CPU usage for some reason. I'm assuming you are running Windows as
well since you mentioned "run in their own window" or are you running Linux and just
have multiple terminals open? Much thanks for this info!
:-)
Listen to this. I have 3 280X.
1 Gigabyte 280X windforce OC
2 Sapphire 280X regular model.
The -t 0,0,1,1,2,2 -a 1 scrypt did not work well enough for my setup. I reached 8400 CPM with it.
I think I found out why.
The sapphires run now each in their own window @ 3496 & 3457 CPM each using 2 threads and -a 1 algorith
The Gigabyte does not like that. It stays around the 1.400 cpm mark. I do use it for the monitor but ok.
So i delete the -a 1 scrypt; 1600 cpm. MEH
So I take it back to basics: 1 thread and no algorith choice.
Now it runs happily at 2.600 cpm.
ODD
So one 280X is not the other 280X and for PTS mining I would RIGHT NOW recommend the Sapphire regular version of the 280X. BUT just because of my own experience. I like the Gigabytes but I can't find the optimal configuration yet.
I am happily chugging away at 9700 cpm in total now with these 3 cards
And @ 1150 shares per hour.
Not too shabby. With the right cards a full rig of 280Xs (5 pieces) would ramp up to 16.500 cpm and 1.800+ spm.
