Know your gear

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.

Rated 5 out of 5 by from Get the most out of your 64bit OSIf you are using a 64bit operating system, it is best to use 4GB or more of RAM. This kit makes it easy to install 4GB of RAM in your system. I used the Crucial Memory Advisor Tool and it recommended this kit as compatible with my motherboard. This memory is not for overclockers. If you are looking for stability and reliability, this 4GB kit is the perfect solution. Each RAM module has a sticker which provides detailed information about the product.

Rated 5 out of 5 by from Tech Services agent of great assistance.As a 65 year old, not-so-tech-savvy person, I had to rely on Crucial's Tech Services agent to answer all my questions and help select the correct RAM upgrade kit for my somewhat outdated Dell PC. The agent was patient with me, answered all my questions and assisted in taking my order. The new cards arrived when promised and the upgrade made significant improvement in the performance of our PC.
