200-pin SODIMM


DDR 200-pin SODIMM: Approximately 2.625 in. by 1.25 in. (66.7 mm by 31.75 mm)
 
DDR2 200-pin SODIMM: Approximately 2.625 in. by 1.18 in. (66.7 mm by 30 mm)

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 and DDR2 SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 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.

        Ordered ram on Sept 4. Today is Sept 12. the rams shipped on Sept 4 via UPS and on Sept 7th it was within 35 miles of my home. At this point it was transferred to the USPS! I live in central Ga and my ram 8 days later is in Jacksonville, Fl. 3-4 day delivery has now turned into more than 9 day delivery. still waiting! when I contacted Crucial, there comment was 3-4 day delivery actually is 14 day delivery, "remember, you didn't pay for it". Sad!

                After following the instructions for choosing new memory modules for my iMac, the first set did not work. After returning the first set through a smooth returns process, the second set of modules did not work either. They were easy to install but the iMac would not start (past initial power up)...again. Crucial service was excellent but the failure of the initial order and the return order will send me elsewhere to find memory.

                        Installing these was a breexe, couldn't have been easier.
                        Replaced 2-1gb and after turning the laptop on, I expected maybe 3.5 GB. But the system came up immediately (faster than usual) showing 4 GB. Also the overall rating went up and I can notice the increase in speed of doing things.Thank you!
