I am putting a dual Opteron 280 system together. From the CPU specs I can see that the FSB is running at 1GHz, but then from the motherboard specs (Tyan S2895)and other postings in this forum I see that DDR400 is the memory to use.
Isn't DDR400 for 800MHz FSB? I was under the impression that the new AMD architecture has the memory on the FSB with no external memory controllers.
The other way that I can see this working is that FSB is only for the link between the processors/HT, and the memory is being separate from the Front Side Bus.
Does anyone know how this works? I just want to make sure that I am not forcing the FSB to run at 800MHz by using DDR400.
