6 Information Update
System Setup Program Updates
Memory Optimizer Technology Feature
The current BIOS update provides a memory optimization feature on the
Memory Information screen of the System Setup Program. The Memory
Optimizer Technology option enables you to set the two DRAM controllers
to work independently in parallel 64-bit mode (Advanced ECC is not
available in this mode) or disable the feature to run the controllers in the
default 128-bit mode with Advanced ECC.
QDMA Mode Feature
On the Integrated Devices screen, a QDMA Mode option is now available for
the Embedded SATA field. When set to QDMA Mode, the embedded SATA
controller supports ATAPI devices at an increased data transfer rate than the
PIO rate that is supported in ATA Mode. A device driver must be installed
on your operating system to use QDMA Mode.

The Demand-Based Power Management option on the CPU Information
screen of the System Setup Program, which enables AMD PowerNow!™
technology features on your CPU(s), is not supported in Red Hat
