► DCT Unganged Mode
DCT stands for DRAM Controller.
Ganged refers to the use of both DRAM controllers within a memory controller acting in con-
cert to access memory. For a description of ganged (128-bit DRAM data width) and unganged
(64-bit DRAM data width) DRAM modes :
Ganged channels (DDR2) :
■
DCT channels A and B can be ganged as a single logical 128-bit DIMM.
■
Offers highest DDR2 bandwidth.
■
Requires both DIMMs in a logical pair to have identical size and timing parameters, both
DCTs programmed identically.
