1.6.3 Installing a DIMM
Note:
Notes on memory limitations:
1. Due to chipset limitations, this motherboard can
only support up to 8 GB on the operating sys-
tems listed below. You may install a maximum
of 2 GB DIMMs on each slot, but only DDR2-
533 and DDR2-667 2 GB density modules are
available for this configuration.
2. Some old-version DDR2-800/667 DIMMs may
not match Intel®’s On-Die-Termination (ODT)
requirement and will automatically downgrade
to run at DDR2-533. If this happens, contact
your memory vendor to check the ODT value.
3. Due to chipset limitations, the DDR2-800 with
CL=4 will be downgraded to run at DDR2-667
by default. If you want to operate with lower
latency, adjust the memory timing manually.
4. Due to chipset limitations, the DDR2-667 with
CL=3 will be downgraded to run at DDR2-533
by default. If you want to operate with lower
latency, adjust the memory timing manually.
5. The total memory may have an 8MB reduction
under Single Channel mode, and a 16MB
reduction under Dual Channel mode because
the address space is reserved for the Intel®
vPro™ Technology and the Intel® Quiet Sys-
tem Technology.
Caution! Unplug the power supply before adding or removing
DIMMs or other system components. Failure to do so
can cause severe damage to both the motherboard
and the components.
