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.

3. Connect the CPU fan cable to the connector on the motherboard
labeled CPU_FAN.
2. Push down two fasteners at
a time in a diagonal sequence
to secure the heatsink and fan
assembly in place.

• Do not forget to connect the CPU fan connector! Hardware
monitoring errors can occur if you fail to plug this connector.
• The retention module of some third-party CPU heatsink and fan
can interfere with chipset components at the bottom of the board.
Before purchasing a separate CPU heatsink and fan, make sure that
it will not interfere with the chipset components.

1.7 System memory
1. 7. 1 Ov er vi ew
The motherboard comes with four 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:
Cha nnel Soc kets
Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
1. 7. 2 Me mo ry c on fi gu ra ti on s
You may install 256 MB, 512 MB, 1 GB, 2 GB and 4 GB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.
• For dual-channel conguration, the total size of memory module(s)
installed per channel must be the same
(DIMM_A1 + DIMM_A2 = DIMM_B1 + DIMM_B2).
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from
the same vendor. Refer to the DDR2 Qualied Vendors List on the next
page for details.
• If you install four 1GB memory modules, the system may only recognize
less than 3 GB 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 3GB is recommended.
