Memory Settings ScreenProcessor Settings ScreenOption DescriptionSystem Memory Voltage Displays the system memory voltage.Memory Operating Voltage(Auto Default)Sets the system memory voltage selection.Memory Operating Mode Displays the type of memory operation if a valid memoryconfiguration is installed. When set to Optimizer mode, thememory controllers run independent of each other forimproved memory performance. When set to Mirror mode,memory mirroring is enabled. When set to Advanced ECCMode, two controllers are joined in 128-bit mode runningmulti-bit advanced ECC. The Spare mode option is presenton systems with the Intel Xeon 5600 series processors only.Option DescriptionC1E (Enabled default) Sets the processor performance state to minimumwhen 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 requirehigh 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.
