DDR2 - MB specs... What the heck is "native support" as co..

It means you don't have to overclock the motherboard's FSB to achieve a DDR
800 setting.

DDR RAM is SDRAM. Synchronous - capital S. It has its own clock. It
doesn't derive its clock from anywhere else i.e. doesn't derive from
the FSB, and doesn't use a multiplier.

thread: where's the multiplier?
ng: alt.comp.hardware.overclocking
date: Jun 2005
(says DDR RAM doesn't use any memory multiplier)


thread: fsb speed - why does it matter?
ng: alt.comp.hardware.overclocking
date: 2004
says that when the word Synchronous (the S in SD), is written with a
capital S, it means has a clock. SDRAM has its own clock. when the
word synchronous is written with a small s e.g. "memory run
synchronous to fsb". it means same speed. thanks to richard hopkins
for that one (so asynchronous means not synchronous). So, SDRAM can
be run asynchronously.

thread: Is Pseudo-Sync the same as "asynchronous mode"?
ng: comp.sys.ibm.pc.hardware.chips
note: relevant, but not that useful.

I recall I once had FSB 100Mhz, and RAM at 133MHz.
Si Sandra said something like memory multiplier 4/3 , or x 4/3
Indeed.
100*4/3 is 133. But that's not how the machine gets the 133 !
Si Sandra was very misleading.


I think there is an advantge, when the FSB speed is the same as the
memory speed.. or maybe, when the effective speeds are the same.
Perhaps the term 'native' means that the FSB will run at that speed
too.
That doesn't seem so special to me.. Almost any system can run RAM at
the same speed as the FSB, and higher.

Thanks guys! I appreciate you taking the time to answer!

Aloha!

(note- he said DDR2 800, not DDR 800 - though it's not of much
consequence)

The speed of the FSB is independent of the speed of the Memory Bus.

I'm not even convinced of your terminology here.. "overclock the
fsb"!!!

you can increase the FSB speed to the maximum supported by the
motherboard and not more. In doing so, you may overclock the
processor. But you're not overclocking the FSB.
And this doesn't affect the memory bus speed - the speed the RAM runs
at..

However, searching, I just found a post.. Below indicates that some
chipsets , new ones too, DDR2 ones, may have a multiplier/divisor for
the RAM.
In which case.. DaveW's terminology of 'overclocking the fsb' is still
wrong.
And the memory bus speed would then be dependent on the FSB. It'd be
derived from the FSB speed, and a multiplier or divisor.
