DRAM Prefetch on CPU Request
NOTE: This option is available on G7 and Gen8 servers with AMD processors.
Depending on the type of application or software being used, the processor constantly prefetches
data from RAM memory to decrease system latency. This option controls those processor prefetches.
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
