C2SBM-Q User's Manual Compatible FPU Code (Available when supported by the CPU.) Set to Enabled to keep the content of the last instruction Operating Code (OPCode) in the floating point (FP) state. The options are Disabled and Enabled. Set to Enabled to mask alignment check exceptions for split-lock transactions. The options are Disabled and Enabled . Split Lock Operation L3 Cache (Available when supported by the CPU.) Set to Enabled to enable the function of L3 Cache to optimize the system and CPU performance. The options are Disabled and Enabled .
Thermal Management 2 (Available when supported by the CPU.) Set to Enabled to use Thermal Management 2 (TM2,) which will lower the CPU voltage and frequency when the CPU temperature reaches a predefined overheat threshold. Set to Disabled to use Thermal Manager 1 (TM1), allowing CPU clocking to be regulated via the CPU Internal Clock modulation when the CPU temperature reaches the overheat threshold. The options are Disabled and Enabled . Adjacent Cache Line Prefetch (Available when supported by the CPU.) The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The CPU fetches both cache lines for 128 bytes as comprised if Enabled. The options are Disabled and Enabled .
Set Maximum Ext. CPUID=3 When set to Enabled, the Maximum Extended CPUID will be set to 3. The options are Disabled and Enabled. Echo TPR Set to Enabled to prevent xTPR messages from being sent to the system. The options are Disabled and Enabled . Set to Enabled to enable the Enhanced Halt State to lower CPU voltage/frequen- cy to prevent overheat. The options are Enabled and Disabled . C1 Enhanced Mode (Available when supported by the CPU.) Note: Please refer to Intel’s web site for detailed information.
