G31-M4 BIOS Manual Hardware Prefetcher The processor has a hardware prefetcher that automatically analyzes its requirements and prefetches data and instructions from the memory into the Level 2 cache that are likely to be required in the near future. This reduces the latency associated with memory reads. Options: Enabled (Default) / Disabled Adjacent Cache Line Prefetch The processor has a hardware adjacent cache line prefetch mechanism that automatically fetches an extra 64-byte cache line whenever the processor requests for a 64-byte cache line. This reduces cache latency by making the next cache line immediately available if the processor requires it as well. Options: Enabled (Default) / Disabled Max CPUID Value Limit When the computer is booted up, the operating system executes the CPUID instruction to identify the processor and its capabilities. Before it can do so, it must first query the processor to find out the highest input value CPUID recognizes. This determines the kind of basic information CPUID can provide the operating system. Options: Disabled (Default) / Enabled Hyper Threading Technology Enabled for Windows XP and Linux4 (OS optimized for Hyper Threading Technology) and disabled for other OS (OS not optimized for Hyper Threading Tec hnolo gy). Options: Enabled (Default) / Disabled 8
