FIX: 4coredual-sata2 8-way bank-interleave 4GB

[Azrael5]

The latest modded bios release numbered as 2.20a has a problem when 8-way bank interleave has been chosen; in this case, since the POST, the system is unable to calculate correctly the amount of RAM (11600MB circa instead of 4096MB(4GB)) stating each DIMM in the single mode. 8-way bank interleave allows the system to increase the bandwidth of memory adding 420 MB/s circa. Is there a way to fix this regression? (A similar model of Asrock 4coredual-vsta appears to have not this problem with official bios when only 2GB of ram are used based on a thread I have red)
