Trust PRO Memory Upgrade to deliver the best in 200-PIN SO-DIMM PC2700 DDR333 laptop & notebook, 184-PIN PC3200 DDR400 desktop for PC and Mac and ECC Registered server modules as well. DRAM manufacturers build the DDR memory we sell, just like they do for Apple, Dell, HP and others, so you know it's going work!

Double data rate SDRAM also called DDR (1) SDRAM was first produced nearly 10 years ago. DDR RAM memory modules was based on the same architecture as very old SDRAM but it doubled the date transfer rates, thus twice or double the data rate or DDR. PIN configuration form factors are: 184-PIN and 144-PIN with other OEM specific proprietary DDR ram modules. DDR RAM is visually differentiated from SDRAM in that SDRAM is a 168-pin DIMM with a double notch at the bottom along the pins one notch just off-center, the other offside. The 184-pin DDR SDRAM has a single off-center notch.
