Capable
If the processor is capable of a particular function or property, this field displays Yes, otherwise No.
Enabled
If a particular function or property of a processor is enabled, this field displays Yes, otherwise No. If a function cannot be enabled or disabled by user, Not Applicable is displayed.
Deprecated
If a particular function or property of a processor is deprecated, this field displays Yes, otherwise column will not be available.
Capabilities Information For Processor On Connector: CPU1
For Intel: | |
---|---|
64-bit Support | Supports 64-bit. |
Hyperthreading (HT) | Intel's implementation of the simultaneous multithreading technology. |
Virtualization Technology (VT) | Intel's virtualization extension to the 64-bit x86 architecture. |
Demand Based Switching (DBS) | A power-management technology developed by Intel
in which the applied voltage and clock speed for a microprocessor
are kept to the minimum necessary to allow optimum performance of
required operations. NOTE: Due to the limitations
of the VMware ESXi version 3.5 operating system on the 11th generation
Poweredge servers, the Demand Based Switching (DBS) field displays
incorrect value. |
Execute Disable (XD) | Allows properly-written applications to mark off memory space as executable, so that code trying to access space above and beyond that will not be executed. |
Turbo Mode | Displays the processor capability. This is a processor capability that can increase the CPU frequency when the system is operating below the thermal, power or current limits. Configure this processor capability under the BIOS setup page. |
For AMD: | |
64-bit Support | Specifies if the installed processor(s) support 64-bit extensions. |
AMD-V | Specifies if the additional hardware capabilities
provided by virtualization technology are available for use. NOTE: Changing this option
results in a system power down of approx. 3-5 seconds after exiting
the system setup program. |
PowerNow | Allows operating system to dynamically adjust processor power states, voltage, and clocking frequencies depending on workload. |
No Execute | Specifies whether execute disable memory protection technology is enabled or disabled. |
Cache Information For Processor On Connector: CPU 1
Use this window to view cache information for each cache present on the microprocessor.
Cache
Cache is small high-speed memory that contains the most recently accessed pieces of main memory. The cache keeps a copy of data or instructions from main memory for quicker retrieval. Cache decreases the amount of time it takes to move data from main memory to the processor and back again. The processor cache is faster than the system's main RAM.
Cache Information For A Particular Processor On Connector n
Some cache devices are internal to the processors on which they reside. When the cache is internal to a processor, the following fields and their values do not appear in the Cache Information for Processor on Connector n window:
- Speed
- Cache Device Supported Type
- Cache Device Current Type
- External Socket Name
The following fields are defined for a cache device on a particular processor. Some fields do not appear if the cache is internal to the processor.
Status | Indicates whether the cache on the processor is enabled or disabled. |
---|---|
Level | Displays the cache level. Primary level cache (L1) is a very fast memory bank located near the processor execution units. Secondary level cache (L2) is a larger staging area that feeds the primary cache. Tertiary level cache (L3), if available, is an additional, larger memory bank which feeds data to the secondary cache. All of these cache levels are located in the processor. |
Max Size | Displays the maximum memory that the cache can occupy in KB. |
Installed Size | Displays the actual size of the cache. |
Type | Indicates whether the cache type is Data or Unified. |
Location | Indicates whether the cache is located on the processor or on a chip set outside the processor. |
Write Policy | Describes how the cache deals with a write cycle.
|
Associativity |
|
Error Correction Type | Identifies the type of error checking and correction (ECC) that this memory can perform. For example, single-bit ECC or multibit ECC. |
