FSB Speeds Explained

The front side bus is the main clock for your CPU, This is basically Intels HTT to all the AMD people, There is 'Actual FSB' And 'Rated FSB' the actuall FSB is what speed your CPU is running at, they work out the rated FSB by quad pumping(QDR) E.G; 266x9= 2400MHz, This is an E6600 which is an '1066FSB' chip(266x4=1066)

With Intel C2D your memory has to run equal or faster to your actual FSB unless your on an nVidia chipset board where you can run your memory unlinked, DDR2 memory is worked out like this:

E6600 = 266/1066 if you are running at 1:1 ration your memory speed would be DDR667(333x2) DDR = Double Data Rate that is why you double the FSB to get your RAM speed

If you keep at 1:1 your memory has to be able to keep up






Just a shorten

Short and sweet, it's nice! However:

E6600 = 266/1066 if you are running at 1:1 ration your memory speed would be DDR667(333x2)

If you're running 1:1, your memory would also run at 266 MHz, giving you DDR2-533. You would need a 4:5 ratio to get 333 MHz on the memory (667 MHz effective). Unless I'm missing something, quite possible
