Overclocking NorthBridge?

Is there a point?

depends

on Phenom IIs and Athlons overclocking the NB/HT link increases performance a lot

on FX chips it makes no difference at all

on Intel its not possible, atleast not that i know of

So what about on APU's? They need to access RAM quickly for graphics, would this allow more bandwidth to the RAM or no?

i believe the trinity APUs are based off the Phenom II architecture, so probably

@phosgene Could you go into more detail about the overclocking of the NB/HT. I have a 965 BE OCed @ 4GHz with just uping the multiplier. Would I gain more speed/FPS If I drop the multiplier down and OC the FSB?

not quite sure how it would be done on Phenom IIs as i skipped from first gen phenoms to piledriver

but you can probably find a guide on overclock.net
