Hardware Prefetcher (Available when supported by the CPU)
If this item is set to Enabled, the hardware prefetcher will prefetch streams of data
and instructions from the main memory to the L2 cache in the forward or backward
manner to improve CPU performance. 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
