MODEL- BL6464AA804        VENDOR- CRUCIAL TECHNOLOGY

FEATURES- Ballistix 240-pin DIMM Module- 512MB
       DDR2 PC2-6400, 4-4-4-12, UNBUFFERED, NON-ECC, DDR2-800, 2.2V,
        64Meg x 64.
       The Ballistix line is specifically built for performance
        enthusiasts who want to push the performance envelope without
        worrying about data loss or corruption, mysterious intermittent
        errors and display problems, or worse -- the dreaded BSOD! The
        Ballistix line of high-performance memory modules features
        advanced speed grades, low latencies, and integrated aluminum heat
        spreaders.
* A Ballistix dual inline memory module (DIMM) consists of a number of
  memory components that are attached to a black printed circuit board. 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.
* Ballistix 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. Ballistix 240-pin
  DIMMs are available in DDR2 PC2-4200 SDRAM (DDR2 533), DDR2 PC2-5300
  SDRAM (DDR2 667), and DDR2 PC2-6400 (DDR2 800).
* 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. (Information about which
  memory technology your system uses is included in the Crucial Memory
  Advisor tool.)
* The number of black components on a Ballistix 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. Ballistix 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.
