Can't get dual channel to work in DS5

We should note the new unganged mode, when the integrated controller acts as two independent 64-bit controllers, which can service memory calls from different processor cores. According to our test results, this is actually a single-channel mode for single-threaded access to a single data block (and it demonstrates appropriate values of real memory bandwidth). However, it becomes much more efficient for multi-threaded access to several data blocks. It becomes even more efficient than the ganged mode of the memory controller, which can be considered a classic modification of the 128-bit dual-channel memory controller. Efficiency of the unganged mode is especially noticeable with fast memory (e.g. DDR2-1066), when it can reach memory bandwidth values of about 85% of theoretical maximum. We have never seen such a big step to revealing the full potential of DDR2-800 and DDR2-1066 memory. And we can now say that the memory controller integrated into AMD processors has finally managed to demonstrate its indisputable advantage over the traditional bus architecture of Intel platforms.
