Advanced Power Management Configuration - Supermicro SUPERO X10DRW-i User Manual

X10DRW-i/X10DRW-iT Motherboard User's Manual
DCU Mode
Use this feature to set the data-prefecting mode for the DCU (Data Cache Unit).
The options are 32KB 8Way Without ECC and 16KB 4Way With ECC.
Direct Cache Access (DCA)
Select Enable to use Intel DCA (Direct Cache Access) Technology to improve the
efficiency of data transferring and accessing. The options are Auto, Enable, and
Disable.
DCA Prefetch Delay
A DCA Prefetcher is used with a TOE (TCP/IP Offload Engine) adapter to prefetch
data in order to shorten execution cycles and maximize data processing efficiency.
Prefetching data too frequently can saturate the cache directory and delay neces-
sary cache access. This feature reduces or increases the frequency the system
prefetches data. The options are [8], [16], [32], [40], [48], [56], [64], [72], [80], [88],
[96], [104], [112].
X2 APIC (Advanced Programmable Interrupt Controller)
Based on Intel's Hyper-Threading architecture, each logical processor (thread) is
assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to En-
able, the APIC ID will be expanded (X2) from 8 bits to 16 bits to provide 512 APIDs
to each thread to enhance CPU performance. The options are Disable and Enable.
AES-NI
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instruc-
tions (NI) to ensure data security. The options are Enable and Disable.
Intel Virtualization Technology
Select Enable to use Intel Virtualization Technology support for Direct I/O VT-d sup-
port by reporting the I/O device assignments to the VMM (Virtual Machine Monitor)
through the DMAR ACPI tables. This feature offers fully-protected I/O resource
sharing across Intel platforms, providing greater reliability, security and availability
in networking and data-sharing. The options are Enable and Disable.
