DDRAM and SDRAM

What brand and type MB??

There is quite a speed difference between SDRAM and DDR.
SDRAM has topped at 133mhz DDR starts at 233 and climbing.

lets assume ill be using the same brand of SDRAM and DDRAM
ASUS motherboard...
i know most of the difference between the two...

im not sure i understand what u meant by "type MB"?

can u shed light further?
thanks ...

What model motherboard(MB)
Unless the board can run the memory at their own speeds (which I haven't seen one yet)And if it truely uses the two different types of ram it would run at the lowest speed ram (SDRAM)

Agree with magarity--you are VERY unlikely to get both types of RAM to run at the same time in the same motherboard. Unless you're seriously short on cash I'd just buy a single 256Mb DDR-RAM DIMM and use it instead of your 128Mb SDRAM DIMM.

Jerome:

Are you considering a MB upgrade but you don't want to dump your old SDRAM, just let it grow using DDR SDRAM in addition?
Is this your case?

cesar,
not exactly like that...im getting a new one and i am gonna use DDRAM  but i can get some SDRAM for free and my MOTHERBOARD has slot for both...

Jerome:

I see you've a nice game plan here: free SDRAM today and buying DDR SDRAM in the future for lower prices than today, but as others experts pointed out, most MBs with 2 types of memory slots will operate in one modality at a time. So the newer DDR SDRAM would really be a replacement and not an addition to plain SDRAM.

thank everyone....i appreciate all the inputs...
i accepted magarity's comment since he got there first...

again... thanks...
