Fsb....

[slvrstang]

agex000 and slvrstang are talking about 2 different things.

slvrstang is refering to the cpu clock speed multiplyer.

agex000 is refering to the FSB's actual speed after multiplied

my question is... ok, ill have to do an example..

1)for Athlon XP's(ex-like a 3200+), there fsb was 200x2= 400. whitch was syncronized with the ram.. ram was the same way pc3200 would do 200x2 = 400fsb.

2)however, for Athlon 64's... there fsb is 200x4 = 800(32bit) ,so how do thy run at this speed? since the ram is still only a multiple of 2x200= 400. i dont think there such a thing as QDR-ram(quadrupal data rate) so could someone explain to me how this works?

The ram runs at 200mhzX2=400mhz (assuming its DDR400/PC3200)

This is a 1:1 ratio with the FSB which is 200

The HT (Hyper Transport) speed is 800mhz=200X4

But say you bought PC2700 the ram would run at 333mhz=166X2 and the CPU would still run at 200mhzx10=2000mhz with the 200X4=800mhz HT but the new CPU/RAM ratio would be 5:3 instead of 1:1.
