SPEC CPU2006 Flag Description - Platform settings
- Utilization Profile:
-
This BIOS switch allows 2 options: "Even" and "Unbalanced". The default is "Even"
and the best choice for all workloads utilizing the whole system. In cases where
the utilization is highly concentrated on few resources of the system the
performance of the application could be improved by setting to "Unbalanced".
-
Setting this option to "Unbalanced" may improve performance but also
increase the power consumption of the system. Users should only select
this option after performing application benchmarking to verify improved
performance in their environment.
- Energy Performance:
-
This BIOS switch allows 4 options: "Balanced performance", "Performance",
"Balanced Energy" and "Energy Efficient". The default is "Balanced Performance"
optimized to maximum power savings with minimal impact on performance.
"Performance" disables all power management options with any impact on performance.
"Balanced Energy" is optimized for power efficiency and "Energy Efficient" for
power savings. The BIOS switch is only selectable if the BIOS switch
"Power Technology" is set to "Custom".
-
The two options "Balanced Performance" and "Balanced Energy" should always be the
first choice as both options optimize the efficiency of the system. In cases where
the performance is not sufficient or the power consumption is too high the two
options "Performance" or "Energy Efficient" could be an alternative.
- Memory Refresh Rate Multiplier:
-
This BIOS switch allows 4 options: 1x, 2x, 3x and 4x. Memory refresh is a process
which periodically read and immediately rewrite the read information to the same
area without any modification, which is typical for DRAM dimms. The default is 2x.
Setting this switch the frequency of memory refresh can be configured, having
an impact on the memory performance.
-
Configuring the refresh rate may depend on the dimm type. The default rate of 2x
is sufficient and safe. Reducing the rate to 1x will optimize the performance
without reducing safety in most cases.
