About this product
Product Information
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.) 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.Product Identifiers

Great for PC Upgrade
I used this to upgrade the RAM in my HP desktop machine to the max RAM it will take. Next I'll upgrade it to Windows 10, but before it would have been a struggle with half the installed memory. Before you junk your vintage desktop, check into the max RAM it will accept and buy it yourself and carefully install it and add life to your machine. Look for new first. If you've not swapped RAM before just watch it done on YouTube etc - you can do it, don't pay to have it done, no software etc changes needed, your system will recognize it as new, ask you to confirm it, and that's it.Verified purchase: YesCondition: New

Old tech lot of life
Not much too RAM as far as I'm concerned. As long as when I install it, it works at its specified speed, I'm happy. That's just what these two sticks of RAM did. No complaints from me.Verified purchase: YesCondition: New

Memory for Debian Linux File Server
I had a very basic need - more RAM for a Dell Optiplex Desktop machine that I turned into a home file server running Debian Linux. So far so good - the RAM has been in the machine for about 6 months with no issue.Verified purchase: YesCondition: New

Great fit for older Vostro 400
Update: added 2nd pair of 2x2gig sticks and motherboard recognizes the 8 gig total ram as well as the OS and test programs......Doc's show Vostro 400 core 2 quad motherboard only takes 1g ram up to 4max. I put the 2 - 2gig sticks in, bios disagreed one round of power cycling and now works fine. Going to add 2 more sticks to push board to 8gig ramVerified purchase: YesCondition: New
