Use the
UPI Bandwidth Optimization (RTID) option to configure the UPI link between processors which provides the best performance for most applications.
NOTE:
This option is only configurable if two or more CPUs are present.
Procedure
From the
System Utilities screen, select
System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > UPI Bandwidth Optimization (RTID).
Select a setting.
Balanced—This option provides the best performance for most applications and benchmarks.
Optimized for I/O (Alternate RTID)—This option can increase bandwidth from I/O devices, such as GPUs that rely on direct access to system memory.
