Installing the Motherboard
1 Install your CPU. Pull up the lever away from the
socket and lift up to 90-degree angle.
2 Locate the CPU cut edge (the corner with the pin
hold noticeably missing). Align and insert the CPU
correctly.
3 Press the lever down and apply thermal grease on
top of the CPU.
4 Put the CPU Fan down on the retention module and
snap the four retention legs of the cooling fan into
place.
5 Flip the levers over to lock the heat sink in place and
connect the CPU cooling Fan power cable to the
CPUFAN connector. This completes the installa-
tion.
CPU Installation Procedure
The following illustration shows CPU installation components.
Installing Memory Modules
K8T890-A accommodates two 184-pin 2.5V unbuffered Double Data Rate (DDR) SDRAM
(Synchronous Dynamic Random Access Memory) memory modules. K8T890-A can sup-
port DDR400/333/266 memory types and its total maximum memory size is 2 GB.
Do not remove any memory module from its antistatic packaging until you
are ready to install it on the motherboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear a
grounding strap when you handle the modules.
DDR SDRAM memory module table
To achieve better airflow rates and heat dissipation, we suggest that you use
a high quality fan with 4800 rpm at least. CPU fan and heatsink installa-
tion procedures may vary with the type of CPU fan/heatsink supplied. The
form and size of fan/heatsink may also vary.
Memory module Memory Bus
DDR400 200MHz
DDR266 133MHz
DDR333 166MHz
Notes: 1. When running dual channel mode, install only same (same density, DRAM
technology and DRAM bus width) module for each deal channel.
2. Please note that those types not in the Table B (p.16) will not boot up.
