Every computer needs memory but more often than not we like to feature the products out of reach for most. Not all of us need or want to spend $200+ dollars on a kit that will guarantee DDR3-2500 speeds. Don’t get me wrong, if a kit were to float by my desk at no cost I’d jump all over it but in reality, times are tough and $200 is a lot to ask for. When it comes to quality budget kits, your choices aren’t as big as you’d think.Crucial, a key brand in the Lexar Media family of products, is not only a DRAM suppler but major manufacturer. You’ve probably seen their brand Micron before and on the shelf they’ve got a huge presence under the Crucial Ballistix line. Not so commonly known is their expansive collection of more budget friendly models available on their website. Today we feature the CT2KIT25664BA1339, a 4GB kit you can own for under $70.
While most companies come up with fancy names for each of their products, Crucial cuts to the chase and sticks with the technical details. The name CT2KIT25664BA1339 is definitely a mouthful of characters but it makes perfect sense to the eyes of an engineer. Without getting into too much detail we have a 2 stick kit with 256MB ICs providing a 64-bit data path. It’s DDR-1333 at CAS 9. It’s unbuffered and operates at a typical 1.5V. More information about the kit is available at Crucial’s website.Here’s what they have to say about their own kit:
Crucial 240-pin DIMMs are used in DDR3 memory for desktop computers. DDR3 is the latest generation of memory with an improved architecture that allows it to transmit data more quickly.
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.
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 DDR3 240-pin DIMMs are currently available in DDR3 PC3-8500 SDRAM. Additional speeds will be added as the technology becomes available.
To use DDR3 memory, your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset. This is because a DDR3 SDRAM DIMM will not fit into a standard DDR2 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 DDR3 DIMMS, 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.
