Re: Official AMD Overclocking Thread.
You can increase them to get better performance in certain applications.
For example, a higher NB speed makes the L3 cache faster (L3 cache runs at NB speed), which helps in superpi.
For 1M runs, pretty much all the data will be in cache, so RAM/HTT speed isn't going to have much if any effect. Though For 32M runs, RAM/HTT speed plays a much bigger part.
But you don't need to increase the HTT/NB speeds exactly.
HT speed is independent of core speed. Though it's linked to NB speed.I've read that you have to up the HT link speed, but I've also heard that at higher clocks, you need a lower HT speed....???

In earlier K10/K10.5 chips, I think a lower HTT speed increased overall stability when overclocking the core (thus higher core clocks were possible), though I don't think it's the case so much with most chips now.Antec-User said:Which one? I understand that if you up the CPU cycles, you have to up the other agencies around it. NB and HT.. But mine doesn't seem to like higher HT's.. 800 seems to be the sweet spot.
