Crucial is the latest company to come to our DDR3
call. We've been reviewing a few kits here, trying to get a grip
on how the DDR3 market is moving. A couple of months ago, DDR3 was
off to a very slow start, but now it seems like companies are
starting to hit their stride and really starting to increase the speed
and tighten the timings. Crucial has sent us over some Ballistix
memory to test out. The speed and timings aren't the best you can
purchase currently, but the Ballistix name implies better memory chips
and PCBs, hopefully. So maybe we can juice these bad boys up and
get some really good results.

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.
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 DDR3 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.
