Hi members,

I need some help to understand the basics of overclocking. I dont really know where to start, i'll try to be has clear as possible. On this post titus asks:
Should the DDR2 memory DRAM Frequency be as close to the Bus Speed of the CPU as possible?

Then paul explain that we should consider the real transfer rate in mb/s of both the memory and the processor bandwidth to match.

Paul calculs:
if you had dual channel memory at PC2-4800 (which is DDR2-600 rate),
the bandwidth might look like 2*4800 = 9600MB/sec
The processor is 8 * FSB800 = 6400MB/sec.

The first calcul is 4800 * 2 because its in dual channel thats ok.. But on the second (8 * FSB800) where does the 8 come from?

I also have some other question about this after someone kindly help me get this clear.
 
With google, i have some progress:

8 counts as the amount of "bits" per data cycle.

Before i can understand this, there comes another question: How can i know how many transfers per Clock Cycle my cpu can do?

Number of cores 2 (max 2)
Number of threads 2 (max 2)

Welcome to the forum. Me I haven't a scooby due about over clocking. But I am sure one of our forum mods V_R will be here to help
