I have a rig with powsercolor 5xR9 280x, win 10, radeon 15.12, 16g memory , 120g ssd driver. When trying to run cm 12.0 at -i 6 I get the following
              GPU #2 is going to use too high intensity (6), not enough memory, intensity value reduced (5)
              GPU #2 algorithm 1, intensity 5
I had 24g of vitual memory allocated and tried the in increments 0f 4g up to 56g and determined there may be some issue.  This last try was with one card at -i 6
gave the above results.  Anyone else have similar problem
