Ram and fsb speed match

[shlib92]

is matching ram with the fsb speed as simple as matching the effective speed of ram(pcxxxx) and the effective speed of fsb, after double pumped etc.

 

[Upendra09]

yes?

basically if your RAm is clocked at 800 mhz then you want the FSb to be at 800


etc.

 

[jsc]

basically if your RAm is clocked at 800 mhz then you want the FSb frequency to be at [strike]800[/strike] 400 Mhz (assuming we are talking about DDR2 memory)

 

[shlib92]

can you please explain in detail why the fsb should be half the speed of the ram thanks

 

[Upendra09]

yeah 400 not 800

because the processor is double pumped

right JSC?

I know this thread is old but I would like to ask a question.

I've been doing to some thinking and wanted know if this was right.

Currently my processor FSB is running at 266MHz and my memory is running at 533Mhz (without DDR)

Now when I do the "formula" for the memory peak transfer rate and FSB, it would look something like this:

64 / 8 *533 *2 = 8528 ( memory )
64 / 8 *266 *4 = 8512 ( CPU FSB )

Does that mean my processor and memory have a perfect flow?
