4GB PCI Hole Granularity

This feature allows you to select the granularity of PCI hole for PCI slots. If MTRRs

are not enough, this option may be used to reduce MTRR occupation. The options

are: 256 MB, 512 MB, 1GB and 2GB.

Memory Branch Mode

This option determines how the memory branch operates. System address space can

either be interleaved between two channels or Sequential from one channel to another.

Single Channel 0 allows a single DIMM population during system manufacturing.

The options are Interleave, Sequential, Mirror, and Single Channel 0.

Branch 0 Rank Interleaving & Sparing

Select enable to enable the functions of Memory Interleaving and Memory Sparing

for Branch 0 Rank. The options for Memory Interleaving are 1:1, 2:1 and 4:1. The

options for Sparing are Enabled and Disabled.

Branch 1 Rank Interleaving & Sparing

Select enable to enable the functions of Memory Interleaving and Memory Sparing

for Branch 1 Rank. The options for Memory Interleaving are 1:1, 2:1 and 4:1. The

options for Sparing are Enabled and Disabled.

Enhanced x8 Detection

Select Enabled to enable Enhanced x8 DRAM UC Error Detection. The options

are Disabled and Enabled.

High Bandwidth FSB

Select Enabled to enable the high bandwidth Front Side Bus (FSB). The options

are Enabled and Disabled.

High Temperature DRAM Operation

When set to Enabled, the BIOS will refer to the SPD table to set the maximum

DRAM temperature. If disabled, the BIOS will set the maximum DRAM temperature

based on a predeﬁ ned value. The options are Enabled and Disabled.

AMB Thermal Sensor

Select Enabled to activate the thermal sensor embedded in the Advanced Memory

Buffer on a fully buffered memory module for thermal monitoring. The options are

Disabled and Enabled.

Thermal Throttle

Select Enabled to enable 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 module exceeds a predeﬁ ned

threshold. The options are Enabled and Disabled.
