Broadwell CPU (E5 2650) with two memory controllers

Hello,

I have a server with one socket (E5 2650 cpu) and 128GB DRAM (8 DIMMS of 16 GB). As it can be seen from the specs the cpu has 12 cores and two integrated memory controllers. The first memory controller uses two channels(channel 0 and 1) and the second one also uses two channels(channels 3 and 4). Although the channel interleaving is disabled through bios (my setting is 1 -way channel interleaving)  there is an interleaving between two channel of different controllers.  The interleaving appears between channels  0 and 2 or 1 and 3. Can i disable this type of interleaving?

Thanks,
