Memory Configurations
The Vig395P with Intel 5000X chipset supports the mirroring and sparing technology.
Mirroring mode:
This mode when enabled in the BIOS Branch 2 contains a replicate copy of the data in
Branch 1. The DIMMs must cover the same slot position on both branches. DIMMs that
cover a slot position must be identical with respect to size, speed, and organisation.
DIMMS within a slot position must match each other, but aren’t required to match
adjacent slot positions.
Refer to page 113
to enable the memory mirroring functions.
And the default BIOS setting is disabled.
The total memories size will be half of all installed memories.
Single Channel mode
:
At configuration time, a DIMM rank is set aside to replace a defective DIMM rank.
When the error rate for a failing DIMM rank reaches a pre-determined threshold, the
memory sparing function will issue an interrupt and initiate a spare copy. At the
completion of the copy, the failing DIMM rank is disabled and the “spared” DIMM rank
will be used in its place. Refer to page 113 to enable the memory sparing functions.
And the default BIOS setting is disabled.
Notes:
1.
Each branch contains its own sparing engine and can be enabled or
disabled
separately.
2. This Motherboard does not support rank sparing across branches.
3. This Motherboard does not support rank sparing when in mirror mode.
4. The DIMM rank with the largest size will be assigned as spare rank. Data can only
be copied from a smaller sized rank to a larger sized one.
5. A DIMM can contain only one or two ranks. To support sparing function, a DIMM
channel should contain at least two ranks.
6. When sparing function is enabled, the usable memory size will reduce then size of
the spare ranks.
