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
