Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware prefetcher will pre fetch 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 CPU fetches both
cache lines for 128 bytes as comprised if

during an attack. The default is
Enabled . (Refer to Intel and Microsoft Web Sites for more
