1.6.2 Installing the CPU heatsink and fan
The Intel® LGA775 processor requires a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the holes
on the motherboard.
•
When you buy a boxed Intel® processor, the package includes the CPU fan
and heatsink assembly. If you buy a CPU separately, make sure that you
use only Intel®-certied multi-directional heatsink and fan.
•
Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design
and requires no tool to install.
•
If you purchased a separate CPU heatsink and fan assembly, make sure
that you have properly applied Thermal Interface Material to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Make sure that you have installed the motherboard to the chassis before you
install the CPU fan and heatsink assembly.
Make sure to orient each fastener with the narrow end of the groove pointing
outward. (The photo shows the groove shaded for emphasis.)
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the CPU
fan connector.

1.7 System memory
1.7.1 Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket.
The gure illustrates the location of the DDR2 DIMM sockets:

1.7.2 Memory congurations
You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
4 GB on the operating systems listed below. You may install a maximum
of 2 GB DIMMs on each slot, but only DDR2-800 and DDR2-667 2 GB
density modules are available for this conguration.
• Some old-version DDR2-800 DIMMs may not match Intel®
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR-667. If this heppens, contact your memory vendor to check
to ODT value.

• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
conguration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
•
For single-channel conguration, install either two single-sided memory
modules or one double-sided memory module.
•
When installing four DDR2 DIMM modules, install the single-sided memory
modules.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
• If you install two 2GB memory modules, the system may only recognize less
than 4GB because the address space is reserved for other critical functions.
This limitation appears on Windows® XP 32-bit operation system which does
not support Physical Address Extension (PAE).
• If you install Windows
®
XP 32-bit operation system, a total memory of less
than 4GB is recommended.
