Ram settings?

Yes, 1:1 is always the best, even though you always have to raise RAM timings, the higher you overclock. Using a RAM divider (running the RAM at anything besides 1:1) gives somewhat of a performance penalty. Just don't sacrifice processor speed, merely because your RAM can't go any faster. Processor speed is what counts most.
 
1:1 means the RAM is running synchronous with the FSB, which means the processor doesn?t have to wait or lose out on idles cycles, when prefetching from main memory.

When running memory asynchronous to the FSB, the processor will drop cycles when waiting for read requests. So if you?re running your RAM on say a 5:4 divider, when the processor tries to fetch data from main memory, instead of receiving data after each cycle as requested on a 1:1 ratio, it has to wait several clock cycles before it can process/read the fetched data.

So basically you are reducing the performance of the processor, as there will be an increase in idle time when running the RAM asynchronous to the FSB.

Another reason why dividers don?t hurt AMD?s memory subsystem, and is thus superior.
