|As far as I have seen, hyper transport is an AMD cpu only thing - and the front side bus speed of any mboard is a different thing. The particular cpu may benefit from a higher FSB (front side bus) speed, but they're two different things. You also need to use the ram speed the particular cpu supports, or faster, at it's highest supported FSB speed to get the max performance from the cpu and the system. |
I've built three systems for others - one with an AM2 mboard and an Athlon 64 X2 6000+, the other with an AM2+ mboard with an Athlon 64 X2 6000+, and one with an AM2+ mboard with an Athlon 64 X2 6400+ ( that's one honkin' cpu ! 3.2 ghz. ) . The Athlon 64 X2 cpus can't benefit from faster than 800mhz / PC6400 DDR2 ram, but Phenoms surely DO benefit from 1066mhz DDR2 ram, on AM2+ and above mboards, and that boosts the fsb speed.
The memory controller is built into the cpu for both types of cpus, it's not in the mboard's main chipset.
