I for one do not understand why is that Intel chipset can handle memory the same whether 2x512 with 4 banks or 2x256 with 2 banks while AMD CPUs cannot do that. This thing goes on and on and it is the problem now as well.
Well I have chips that run monstrous frequencies with the most aggressive latencies in Intel board of mine but they cannot manage anything close to that in AMD board.What do you mean high frequency and low latencies?
That hasn't been my observation. I wish I had a dollar for every time a panicky i875P or i865PE owner has destabilized his system by using 2-2-2-6 timings at DDR400 speeds. Like this guy and about 100 other people I've referred to that thread for the same cure.Originally posted by: joe2004

Try overclocking with :
1. 4 banks 2x512
2. 2 banks 2x256
3. 1 bank 1x256
...
in AMD board, whichever setup, for example in K8 board. You will quickly notice that AMD emory controller has serious problem with multiple banks setup or with low latencies combined with multiple banks. It is better than in N-Force 2 boards but still a far cry from what Intel setups can do. I love AMD chips and use them in most of my computers but the truth is they are not capable of memory handling the way Intel chips are.
