I'm getting ready to make the plunge to A64 and I am trying to figure out the overclocking basics before I make any purchasing decisions. Since the A64 architecture is so different, there are lots of how-to overclocking articles but, but all the ones I have seen (including the above sticky) assume a certain amount of terminology. So I see lots of terms thrown around that I only have a vague knowledge of what they mean. For example, I know that the HTT is roughly equivalent to the PCI bus and the memory speed is adustable like the old fsb, but what the hell is the LDT? Also, the way people switch back and forth between talking about multipliers and dividers is baffling (two ways of talking about the same bus, or two different adjustments?)
So, I guess my questions are:
1) What are the relevent speeds to pay attention to?
a) cpu-obvious
b) memory-I'm assuming that this is both the bandwidth and the switching speed in the memory chips, or is the bandwidth tied to the cpu frequency?
c) HTT-is this just like the PCI bus?
d) video bus-what replaces the agp bus on PCIe boards? what affects this speed?
e) LDT-what the hell is this?
f) anything else?
2) Which of these speeds are really independent of each other?
3) What are the settings in bios that actually adjust these speeds?
To give you the idea of the kind of answer I'm looking for, if I were to answer these questions for an XP system it would go something like this:
The relevent speeds are the cpu, memory, fsb, agp bus, and pci bus. However, there are only two settings that can be independently adjusted in bios, the multiplier and the fsb. The pci, agp, and memory all run at fixed multiples of the fsb (unless the mobo has a pci lock which freezes the pci and agp speeds). The cpu speed is manipulated independently of the fsb by adjusting the multiplier (which only affects the cpu speed).
If there is an article that explains all this, please let me know.
Thanks.
