ROG STRIX X670E Series BIOS Manual
DF Common Options
Memory Addressing
Memory interleaving
Configuration options: [Disabled] [Auto]
Memory interleaving size
Controls the memory interleaving size. The valid values are AUTO, 256 bytes, 512 bytes,
1 Kbytes, or 2 Kbytes. This determines the starting address of the interleave (bit 8, 9, 10
or 11).
Configuration options: [256 Bytes] [512 Bytes] [1KB] [2KB] [Auto]
DRAM map inversion
Inverting the map will cause the highest memory channels to get assigned the lowest
addresses in the system.
Configuration options: [Disable] [Enable] [Auto]
Location of private memory regions
Controls whether or not the private memory regions (PSP, SMU and CC6) are at the top
of DRAM pair or distributed. Note that distributed requires memory on all dies. Note that
it will always be at the top of DRAM if some dies don’t have memory regardless of this
option’s setting.
Configuration options: [Distributed] [Consolidated] [Consolidated to 1st DRAM pair] [Auto]
ACPI
ACPI SRAT L3 Cache as NUMA Domain
[Disabled] Memory Addressing \ NUMA nodes per socket will be declared.
[Enabled] Each CCX in the system will be declared as a separate NUMA
domain.
[Auto] Sets to the default option.
Disable DF to external downstream IP Sync Flood Propagation
Disables Error propagation to UMC or any downstream slaves eg. FCH. Use this to
avoid reset in failure scenario.
Configuration options: [Sync flood disabled] [Sync flood enabled] [Auto]
Disable DF sync flood propagation
Disables propagation from PIE to other DF components and eventually to SDP ports.
Configuration options: [Sync flood disabled] [Sync flood enabled] [Auto]
Freeze DF module queues on error
This item allows you to enable or disable freezing of all DF queues on error and also
forces a sync flood on HWA even if MCAs are disabled.
Configuration options: [Disabled] [Enabled] [Auto]
DF Cstates
When DF Cstate feature is set to
[Enabled], FW programs the registers required
to enable this feature is the DF HW. (For [Auto] option, it means this option will
synchronize with Global C State).
Configuration options: [Disabled] [Enabled] [Auto]
PSP error injection support
Configuration options: [False] [True]
