CPU1 Core Disable Bitmap / CPU2 Core Disable Bitmap

Available Bitmap:
This feature displays the available bitmap.
Disable Bitmap
Enter 0 to enable this feature for all CPU cores. Enter FFFFFFFFFFF to disable this feature
for all CPU cores. Please note that at least one core per CPU must be enabled. Disabling
all cores is not allowed. The default setting is 0.
Hyper-Threading [ALL]
Select Enable to use Intel Hyper-Threading Technology to enhance CPU performance. The
options are Enable and Disable.
Hardware Prefetcher
If this feature is set to Enable, the hardware prefetcher will prefectch data from the main
system memory to Level 2 cache to help expedite data transaction to enhance memory
performance. The options are Enable and Disable.
Adjacent Cache Prefetch
Select Enable for the CPU to prefetch both cache lines for 128 bytes as comprised. Select
Disable for the CPU to prefetch both cache lines for 64 bytes. The options are Enable and
Disable.
DCU Streamer Prefetcher
If this feature is set to Enable, the Data Cache Unit (DCU) streamer prefetcher will prefetch
data streams from the cache memory to the DCU to speed up data accessing and processing
to enhance CPU performance. The options are Enable and Disable.
DCU IP Prefetcher
This feature allows the system to use the sequential load history, which is based on the
instruction pointer of previous loads, to determine whether the system will prefetch additional
lines. The options are Enable and Disable.
LLC Prefetch
If this feature is set to Enable, LLC (hardware cache) prefetching on all threads will be
supported. The options are Disable and Enable.
Extended APIC (Extended Advanced Programmable Interrupt Controller)
Based on the Intel Hyper-Threading technology, each logical processor (thread) is assigned
256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to Enable, the APIC ID will
be expanded from 8 bits to 16 bits to provide 512 APIDs to each thread for CPU performance
enhancement. The options are Disable and Enable.
