8rda+ FSB newby question

Why does the book claim it can achieve a FSB of 200/266/333 MHZ and then I read where people cannot even achieve 200MHZ?

What am I misunderstanding here?

Cut those number in half, and thats what you actually put into the bios. so if in ur bios it sais ur FSB is at 100mhz its really at 200mhz, and 200mhz being 400mhz....pretty sure im right someone correct me if im wrong.

That makes sense to me for some reason. So is that multiplied by something such as voltage???

Oh and thanks for the reply and to everyone else thanks in advance.

It's simply multiplied by 2. The memory it utilizes is Double Data-Rate (DDR). DDR Ram transmits data on both the rising and falling edge of the clock cycle. So while it operates at 133mhz, it THEORETICALLY transmits data as if it were operating at 266mhz. That is where the multiplier comes in, which is simply x2.
