The front side bus (FSB) is the physical bi-directional data bus that carries signals between the
central processing unit (CPU) and other devices within the system, such as random access memory
(RAM), AGP video cards, PCI expansion cards, hard disks, the memory containing the system
BIOS, etc. A higher bandwidth FSB improves performance of the system. The options are Enabled
and Disabled.
When set to Enabled, the BIOS will refer to the SPD table to set the maximum DRAM
temperature. When set to Disabled, the BIOS sets the maximum DRAM temperature based on a
predefined value. The options are Enabled and Disabled.
Select Enabled to enable the thermal sensor embedded in the Advanced Memory Buffer on a fully
buffered memory module for thermal monitoring. The options are Disabled and Enabled.
Select Enabled to enable the function of closed-loop thermal throttling on a fully buffered (FBD)
memory module. In the closed-loop thermal environment, thermal throttling will be activated
when the temperature of the FBD DIMM device exceeds a predefined threshold. The options are
Enabled and Disabled.
Select Enabled to enable open-loop global thermal throttling on a fully buffered (FBD) memory
module to make it active whenever the number of activate control exceeds a predefined number.
The options are Enabled and Disabled.
Select Enabled to configure FBD clock settings to support ITK testing. The options are Disabled
and Enabled.
