CMX512-3200LL The CMX512-3200LL is a 512 MByte, two bank, ultra-low-latency DDR SDRAM DIMM screened specifically for gaming applications. The part has been designed with a special ultra-low-latency SPD program, which configures it to automatically boot up with optimal latency settings in most motherboards. Since configuration is automatic, there is no need to adjust BIOS settings to attain maximum performance. The impact of these low latency settings are shown below; for chip sets such as the KT.
