BIOS.ProcSettings.CpuFeatureFsrm (Read or Write) Description Enables or disables Fast Short REP MOVSB support. This setting can affect performance, depending on the application running on the server. Legal Values ● Enabled ● Disabled Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.ProcSettings.CpuFeatureRmss (Read or Write) Description Enables or disables REP-MOV/STOS Streaming support. This setting can affect performance, depending on the application running on the server. Legal Values ● Enabled ● Disabled Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.ProcSettings.CpuInterconnectBusSpeed (Read or Write) Description This setting governs the frequency of the communication links among the CPUs in the system. Note that standard and basic bin processors support lower link frequencies than the advanced parts do. Maximum Data Rate indicates that the BIOS will run the communication links at the maximum frequency supported by the processors. You can also select specific frequencies that the processors support, which can vary. For best performance, you should choose the Maximum Data setting. Any reduction in the communication link frequency will affect the performance of non-local memory accesses and cache coherency traffic. In addition, it can slow access to non-local I/O devices from a particular CPU. However, if power saving considerations outweigh performance, you may want to reduce the frequency of the CPU communication links. If you do this, you should localize memory and I/O accesses to the nearest NUMA node to minimize the impact to system performance. Only available if 2 or more CPUs are present. On 14G only MaxDataRate, 10GTps, and 9GTps Legal Values ● MaxDataRate ● 10GTps ● 9GTps Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable 294 BIOS Attributes
