Configuring Cache Memory - Epson User Manual

Configuring cache memory

Enabling cache memory improves system performance when
retrieving and processing large amounts of data on systems
with external cache installed. To avoid possible configuration
problems, leave these options at their default settings unless a
peripheral you have installed requires that you make changes.
See your peripheral documentation for information.
The table below lists the memory cache options.
