The "-SO" cards have no external off-chip memory, as seen above. If it did have off-chip memory there would be a "MC0" and possibly "MC1" lines above with a large amount of memory. Like this (T580-CR):
MC0: 0x600000-0x405fffff [1.00 GiB]
MC1: 0x40600000-0x805fffff [1.00 GiB]
So your -SO cards will only handle a very small amount of RDMA load.
Steve.
