North Bridge submenu
The North Bridge submenu allows you to configure settings for the
Intel 5520 chip.
Setting the items below to the wrong values can cause the unit to malfunction.
Meaning
This item reports the total installed memory on the Matrox Supersight SHB-5520 board, in GBytes.
This item reports the current memory mode. To set this item, use the Memory Mode item, later in this
submenu.
This item reports the current memory speed.
This item reports whether memory mirroring is supported. With memory mirroring, two identical copies of all
data are maintained in the memory modules and the total memory available to the CPU is reduced.
This item reports whether memory sparing is supported. With memory sparing, a block of memory with a
specified number of errors will be copied to another block of memory.
This item allows you to set the memory distribution scheme for the memory modules.
When set to Independent, this mode allows all the system memory (over the various installed memory
modules) to be used as a single contiguous block of memory. This allows the CPU cores to use all memory
channels simultaneously, if possible. This is the only mode that supports non-ECC memory modules.
Note that your Matrox Supersight SHB-5520 only supports non-ECC memory modules. Therefore, all other
❖
memory modes are not supported.
This item allows you to enable non-uniform memory access (NUMA). The NUMA memory architecture of the
Intel Xeon Quad-Core processors allows each processor core to access memory locations faster than the
traditional method (where all memory access is provided by the shared memory channels).
Older versions of the Microsoft Windows operating system (for example, Microsoft Windows 95) might not
❖
support NUMA. See the documentation that accompanies your operating system for more information.
