Oh, I get it, the faster the CPU the better performance on Dual Channel too right?
I think this is how it works.....
for PC2-6400..... 6400/8 = 800MHz, so for 5300 is actually 5336/8 = 667MHz
Now if you have RAM at 1000MHz, its PC2-8000 = 1000MHz. 1000MHz in Dual Interleave/Channel has a bandwidth of 16 GB/s.
And there is a PC2-10664 which they say is PC2-10000 and has a Bandwidth of 20 GB/s.
I think I get how PC2-(Value Here) and how it works now. Hehe
I think thats how it is.... The "Value Here" is the bandwidth and in dual channel its two times the "Value Here"
But it wont really become effective untill CPU's will reach the same bandwidth.
So with a CPU that has a 1066MHz FSB its Bandwidth is 8 times the FSB which is 8532 MB/s or 8.5 GB/s
So a 1333 MHz FSB will have 10667 MB/s. So for the PC2-6400 to be effective at 12.8GB/s you need to have a 1600MHz FSB on your CPU and run 1:1 ratio.
So PC2-6400 running at 800MHz and your CPU has an FSB of 1600MHz which is 400MHz FSB on the BIOS. The 1600MHz FSB is the "Effective" and on C2D and C2Q its 4 times the FSB.
So if you have say..... CPU with 400Mhz and 8 Multiplier its 3.2GHz and 1:1 FSB:RAM ratio you will get both the same CPU and Memory Bandwidth which will be 12.8 GB/s.
Wow, this Frequency and bandwidth stuff is awesome. I never knew how they figured out the bandwidth until now.
So right now, the CPU is lagging behind the Memory Technology. The memory speeds are way ahead of the CPU's. The PC2-6400 is meant to be designed and work greatly with a 1600MHz Effective FSB CPU's which is not out yet. This is without Overclocking.
