The box came in the mail just a couple of days. That was sure fast. I made the order through Crucial Technology on Sunday and within two days it had arrived.
Ran upstairs, cranked open the computer, carefully pushed in the new DIMM, closed the computer and replaced all the cables, plugged it in and turned my beautiful Dell on. Now it literally screams, screams and is super fast. When I click on [Control Panel>>System>>General] I see 1.00 GB of RAM. This should last me a couple years I hope.
This is the explanation as given by the kind folks at Crucial:
"A dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold or tin pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected, providing two lines of communication paths between the module and the system."
"184-pin DIMMs are used to provide DDR SDRAM memory for desktop computers. Each 184-pin DIMM provides a 64-bit data path, so they are installed singly in 64-bit systems. 184-pin DIMMs are available in PC2100 DDR SDRAM or PC2700 DDR SDRAM. To use DDR memory, your system motherboard must have 184-pin DIMM slots and a DDR-enabled chipset. A DDR SDRAM DIMM will not fit into a standard SDRAM DIMM socket. (Information on which memory technology is used by your system is included in the Memory Selector.)"
"The number of black components on a 184-pin DIMM may vary, but they always have 92 pins on the front and 92 pins on the back for a total of 184. 184-pin DIMMs are approximately 5.375" long and 1.25" high, though the heights may vary. While 184-pin DIMMs and 168-pin DIMMs are approximately the same size, 184-pin DIMMs have only one notch within the row of pins."
In case any of the computer nerds were interested I just thought I would mention it here.
