What is the difference?
I just checked my PC and I have 1 256MB(PC133 SDRAM) for memory

my mother board has 3 slots

how can i tell if my computer supports DDR?
i want to add another stick of memory but not sure if you can mix the two types of memory??? my gut tells me no

my motherboard is a Matsonic MS9107C
can anyone give me any information on this MB and what it supports??

yeah it helps a lot

but whats the difference between SDRAM and DDR?
for this motherboard, what should i install? I want to add a 512mb memory stick....should it be SDRam or DDR...or does it even matter with this particular MB?

Sorry dude, missed a bit

SDRAM stands for Synchronous Dynamic Random Access Memory. DDR is short for "DDR SDRAM" and stands for Double Data Rate. Nowadays to awoid misuderstandings SDRAM is often spicified as SDR SDRAM and SDR stands for Single Data Rate by analogy with DDR. Therefore, the main difference between SDR and DDR memory the doubled speed: DDR can transfer data at roughly twice the speed of SDRAM. For example, PC133 SDRAM runs at 133 Mhz, while 133 Mhz DDR effectively runs at 133 Mhz x 2 = 266 Mhz.
SDRAM has 168 pins and two notches at the connector, which prevents it from being used in a DDR SDRAM motherboard and vice versa. It comes mainly in PC66, PC100 and PC133; the bus speeds of the RAM in MHz.
DDR SDRAM has 184 pins and a single notch at the connector. It comes in speeds of PC1600 (166 MHz), PC1800 (200 MHz), PC2100 (266 MHz), PC2700 (333 MHz), PC3200 (400 MHz), and PC4400 (550 Mhz). The numbers represent the theoretical maximum bandwidth of the DDR SDRAM in Megabytes per second (MB/s). For example, PC2100 has a theoretical maximum bandwidth of 2100 MB/s.


for your MB you will need DDR
