Crucial Ballistix 4GB DDR3-1866 BL2KIT25664FN1869
Feb 16th, 2011 | By JaredWhile most companies come up with fancy names for each of their products, Crucial cuts to the chase and sticks with the technical details aside from the Ballistix name. The name BL2KIT25664FN1869 is definitely a mouthful of characters but it gives you the general information you need. Without getting into too much detail we have a 2 stick kit with 256MB ICs providing a 64-bit data path. It’s DDR3-1866 at CAS 9. It’s unbuffered and operates at a 1.65V. More information about the kit is available at .
Here’s what they have to say about their own kit:
What is Ballistix memory?
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.
For more information about the Ballistix memory line, please visit the Ballistix section of our Web site.
What is a Ballistix DDR3 240-pin DIMM?
Ballistix 240-pin DIMMs are found in DDR3 memory. DDR3, the next generation of memory, boasts an improved architecture allowing very fast data transmission. Ballistix 240-pin DIMMs are available in
PC3-12800 SDRAM (DDR3-1600).
A Ballistix dual inline memory module (DIMM) consists of a number of memory components attached to a black printed circuit board. Gold pins, found 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.
To use DDR3, your system motherboard must have 240-pin DIMM slots and a chipset that supports DDR3, which is a different technology than that of than its predecessors, DDR2 and DDR. DDR3 incorporates different sockets; they are not interchangeable or backward-compatible. (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. These 240-pin DDR3 DIMMs have only one notch within the row of pins, and each technology has the notch in a slightly different location on the module.
