Dram Prefetch On I/O Request - HP ProLiant DL360e User Manual

DRAM Prefetch on I/O Request

NOTE: This option is available on G7 servers with AMD processors.
Depending on the type of I/O and expansion cards being used, the processor constantly prefetches
data from RAM memory to decrease latency within the I/O subsystems and expansion cards. This
option controls those processor prefetch features.
In most cases, this option should remain enabled. With certain workloads, however, disabling this
option may provide a performance benefit. Disable this option only after performing application
benchmarking to verify improved performance in a particular environment.
Options include:
Enabled (default)
Disabled
122 RBSU menu-driven interface (G7 and later servers)
