Hi, I have two PE R610s and am trying to balance the available physical memory that I have between the CPUs of each PE  R610 as well as each R610 in general. I have 6x 8GB and 6x 4GB modules. I have tried to tinker with a few different combinations but can't seem to balance it so it doesn't throw the "F1 to continue, F2 to enter System Setup" prompt.
