Corsair XMS3200 & XMS3000C2

Corsair Memory has announced that it
is now offering two new 512 megabyte
modules tailored specifically for
overclocking applications. The first
part, Corsair part number CMX512-3200,
is guaranteed to operate at 400 MHz.
The second part, part number CMX512-3000C2,
is guaranteed to operate at 370 MHz,
but with a column access strobe latency
("CAS latency") of only two clock cycles.
Both modules are available immediately.

Each CMX512-3200 is tested in a test
fixture based on a currently
popular motherboard based on a
performance chip set such as Via's KT333
Athlon or SiS' 645 Pentium IV platform.
The testing rig is set to exhaustively

exercise the memory at the following
settings:

Memory bus speed: 2x200 MHz
CAS latency: 2.5 clock cycles
RAS precharge: 3 cycles
RAS-to-CAS delay: 3 cycles
RAS active to precharge: 6 cycles
Command rate: 2T (2 cycles)
Population: 1 module/system

The CMX512-3000C2 is built using
the same components as the CMX512-3200,
and will provide the user with very
similar performance. However, it is
tested with more aggressive latency
settings, as many customers prefer
to configure their systems that way.
The CMX512-3000C2 is tested using the
following settings:

Memory bus speed: 2x185 MHz
CAS latency: 2.0 clock cycles
RAS precharge: 3 cycles
RAS-to-CAS delay: 3 cycles
RAS active to precharge: 6 cycles
Command rate: 1T (1 cycle)
Population: 1 module/system

Corsair's lab testing results also
indicate that the modules will also
easily meet two critical performance
points. The first of these is ultra-low
latency (2-2-2-5-T1) at 2x166 (333) MHz,
a setting used by enthusiasts who optimize
their performance based on low latency
settings. The second is ultra-high
density (2.5-3-3-6-T2, 2x185 MHz)
with two modules (1 gigabyte) of
memory installed in the system, a
typical requirement for users performing
scientific and modeling applications
