Setting QPI Bandwidth Optimization (RTID)
NOTE: This option is available on Gen8 with Intel processors.
The QPI link between two processors provides the best performance for most applications.
To set QPI Bandwidth Optimization:
1.
From the System Utilities screen, select System Configuration
→BIOS/Platform Configuration
(RBSU)
→Power Management→Advanced Power Options→QPI Bandwidth Optimization (RTID)
and press Enter.
2. Select one of the following options:
•
Balanced (default)—Provides the best performance for most applications and benchmarks.
•
Optimized for I/O (Alternate RTID)—Increases bandwidth from I/O devices, such as GPUs
that rely on direct access to system memory. This option is only configurable if two or
more CPUs are present.
3. Press F10 to save your selection.
NOTE: Setting this option to Optimized for I/O can have a negative impact on memory and
system performance.
