AMD SouthBridges - SB600 vs SB700 vs SB750 - whats the difference ?
The question is pretty simple I suppose. What is the difference between the three southbridges found on AMD motherboards ? I know for one that the 600 indicates that its in the 6xx chipset line and the 700 indicates that its in the 7xx chipset line. But in real world terms, what is the difference between the three ?
SB600 supports SATA2. It for sure has some USB problems, though.
Ya it supports Sata 2, but it cannot however do 64-bit DMA transfers. The chip claims it can but in reality it can't. That's why when you boot into a SB600 based system you get a message telling you from the kernel saying 64-bit dma has been disabled and reverts to 32-bit.
