        Crucial brand products are sold in Canada, but not with the best selection and at much higher prices. Service from your US office was quick but the shipping (at approx. $25) was expensive for two small RAM sticks. I would have been happy with a slower cheaper option by US mail instead of FedEx.

          I've been looking for about a year to upgrade my Intel C2D MB and this was perfect. I needed 4GB DDR2 RAM that couldn't be found at a reasonable price until recently. The online scan tool may have been enough for me to buy Crucial RAM but the price was also the best I could find. All around good deal and good technology. This will be the first place I go to find memory upgrades from now on.

                When I first built this PC, I wanted and tried to use Crucial 2GB pairs, but they didn't work in my Rev 1.1 board. Had to use other brand. Decided to upgrade and Crucial is only 4GB available. Still only says works with Rev 1.0 board, but these actually worked with my Rev 1.1. When available, I prefer Crucial. Still deciding if I want another set to go from 12GB to 16GB.

                  240-pin DIMM

                  240-pin DIMM for DDR2 memory
                  Approximately 5.25 in. by 1.18 in. (133.35 mm by 30 mm)

                  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 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 to each other.

                  240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast.

                  Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or Fully Buffered modules). (The Ballistix™ and Ballistix Tracer™ high-performance memory do not come in 72-bit or registered modules.)

                  Standard DDR2 240-pin DIMMs are available in DDR2 PC2-3200 SDRAM, DDR2 PC2-4200 SDRAM, DDR2 PC2-5300 SDRAM, and PC2-6400 SDRAM.

                  To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket.

                  The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins. The notch in a 240-pin DDR2 DIMM is closer toward the center of the module.

                  Ballistix and Ballistix Tracer 240-pin DIMMs

                  Our high-performance Ballistix 240-pin DIMMs come in DDR2 PC2-5300 SDRAM, DDR2 PC2-6400 SDRAM, and DDR2 PC2-8000 SDRAM. The Ballistix Tracer illuminated, activity-indicating high-performance 240-pin DIMM comes in SDRAM, DDR2 PC2-6400 SDRAM, and DDR2 PC2-8000 SDRAM

                  For more information about the Ballistix memory line, please visit the Ballistix section of our Web site.
