memory qustion

hi guys ,
The title say it all.Need some idea.thanks

More bandwidth with DDR.

 

[ALstonLoong]

wats the used of getting more bandwidth ? i thought sdram should be faster then ddr ram ?

 

[hifimaster]

DDR is faster (double data rate).The memory on a video card is one of the biggest bottleneck (so I heard).The memory on my video card is 460mhz (230xDDR).

 

[lazyboy]

yes that is why overclocking the memory helps so much. its a huge bottleneck.

but i cant seems to see any benefit of ddr in geforce2mx card. if do pls tell me.

Current GPU's are primarily limited by their memory bandwidth - Graphics processors are far outstripping the memory that's available to support them. DDR RAM offers significantly higher bandwidth than regular SDRAM, & is currently the memory of choice for video cards. QDR RAM (quad), I believe, is in development, & should provide a nice boost in bandwidth as well.

qdr ram ? interesting .... will that be future ram in our mobo?

 

[Viper GTS]

Who knows, maybe. DDR is just now making it to motherboards, so QDR is probably a ways off.

DDR on the MX is a waste.

A regular GF2 MX runs 128bit SDR memory, the DDR version runs 64bit DDR memory...so they are essentially the same. There are no real performance gains - it's all just a marketing ploy. Now if they used 128bit DDR on the MX it would basically be a GTS.

 

[ALstonLoong]

so wat you mean is there is no benefit with using ddr in gfirce2mx card right?

 

[kami]

yes.

 

[ALstonLoong]

emm....thats really a waste.

 

[Viper GTS]

emm....thats really a waste.

Not if it brings in money for the manufacturer.

People see &quot;DDR&quot; and equate that with performance, without realizing that the plain old SDRAM version will give equal or better performance due to it's wider memory path.

i doesnt wanna start a new thread so i start here........
Does be6 mobo support 2 256mb ram ? And for via chipset mobo , is it can support more then 3 256mb ram ? thanks

 

[Degenerate]

i dont think there is a faster ram. Each ram type is suited for each processor. RDRAM for P4's and DDR for Tb...

or something similar
