Memory Settings Screen Option Description System Memory Voltage Displays the system memory voltage. Memory Operating Voltage Sets the system memory voltage selection. (Auto Default) Memory Operating Mode Displays the type of memory operation if a valid memory configuration is installed. When set to Optimizer mode, the memory controllers run independent of each other for improved memory performance. When set to Mirror mode, memory mirroring is enabled. When set to Advanced ECC Mode, two controllers are joined in 128-bit mode running multi-bit advanced ECC. The Spare mode option is present on systems with the Intel Xeon 5600 series processors only. Processor Settings Screen Option Description Intel(R) TXT (Disabled default) Enables/disables Trusted Execution Technology. To enable TXT, enable & activate VT & TPM with pre-boot measurement. C1E (Enabled default) Sets the processor performance state to minimum when the system is idle. Intel QPI Bandwidth Priority (Compute default) Sets the bandwidth priority to compute or I/O. Recommended for HPC applications. Adjacent Cache Line Prefetch (Enabled default) Enables high utilization of sequential memory access. NOTE: Disable this option for applications that require high utilization of random memory access. Hardware Prefetcher (Enabled default) Enables or disables the hardware prefetcher. DCU Streamer Prefetcher (Enabled default) Enables Data Cache Unit streamer prefetcher. Recommended for HPC applications. Data Reuse (Enabled default) Enables or disables data reuse. Recommended for HPC applications.
