A small outline dual inline memory module (SODIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected.

200-pin SODIMMs are used to provide DDR SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2100 DDR SDRAM, PC2700 DDR SDRAM, and PC3200 DDR SDRAM. To use DDR memory, your system motherboard must have 200-pin SODIMM slots and a DDR-enabled chipset. A DDR SODIMM will not fit into a standard SDRAM SODIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.

The set we are looking at in question is workable at 400mhz (200) with  “3, 3, 3, 9” timings and at 533 with “4, 4, 4, 12” timings. Also as most laptops that would use this come with dual channel support, getting the 2x512 kit means, we will see the laptop jump to dual channel mode with these installed and that is before the benefit of the 1gig upgrade. The specs are pretty impressive for the ram and I just want to see if the increase in performance will let the laptop handle 20x 4.60-6.0 meg pictures our camera produces. Put it this way, the laptop with its current 256mb can only open 4 of these before we start to see system lag. Especially when working with layers within pictures.

Before we test to find out let us take a look at the product itself
