CPU L1 & L2 Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The settings enable/disable the internal cache (also known
as L1 or level 1 cache) and external cache (also known as L2 or level 2 cache).
Setting options: Disabled, Enabled.
CPU L3 Cache
Level 3 cache is the extra cache built into motherboards between the micro-
processor and the main memory. Located away from the CPU, the L3 cache is
slower than the L1 & L2 caches. This setting allows you to turn on or off the
L3 cache. Setting options: Enabled, Disabled.
