X7DWE User's Manual

Intel VT for Direct I/O (VT-d)

Select Enable to enable the functionality of the Intel Virtualization Technology for Direct I/O VT-d support by reporting the I/O device assignment to VMM through the DMAR ACPI Tables. This feature offers fully-protected I/O resource-sharing across the Intel platforms, providing the user with greater reliability, security and availability in networking and data-sharing. The settings are Enabled and Disabled. Press the <Enter> key to enter the submenu.

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 Voltage Auto-Detect

Set to Enabled to allow the BIOS automatically detect the memory voltage accord- ing to its SPD table. Select 1.5V-Forced to use low-power fully-buffered DIMMs (FBDIMM). Select 1.8V-Forced to use 1.8V memory for testing. (Using the 1.8V- Forced setting may be harmful to some 1.5V FBDIMM.) The options are: Auto- Detect, 1.5V-Forced and 1.8V-Forced.

Memory Branch Mode

This option determines how the two memory branches operate. System address space can either be interleaved between the two branches or Sequential from one branch to another. Mirror mode allows data correction by maintaining two copies of data in two branches. Single Channel 0 allows a single DIMM population dur- ing system manufacturing. The options are Interleave, Sequential, Mirroring, and Single Channel 0.

Branch 0 Rank Sparing/Branch 1 Rank Sparing

Select Enable to enable the function of memory sparing for Memory Bus Branch 0 or Branch 1. The options are Enabled and Disabled.

Branch 0 Rank Interleaving/Branch 1 Rank Interleaving

Select enable to enable Interleaved Memory for Memory Bus Branch 0 Rank or Branch 1 Rank. The options for Memory Interleaving are 1:1, 2:1 and 4:1.

Enhanced x8 Detection

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