Install the Motherboard
Followthestepsbelowinordertoperformtheinstallationofyournew SY-6IEB
Motherboard.
Step 1. Install the CPU
Mark your CPU Frequency: RecordtheworkingfrequencyofyourCPU
thatshouldbeclearlymarkedontheCPUcover.

266MHz(66 x4.0) 333MHz (66 x 5.0) 400MHz(66 x6.0)
300MHz(66 x4.5) 366MHz (66 x 5.5) 433MHz(66 x6.5)
CPU Mount Procedure: Tomounttheprocessorthatyouhavepurchased
separately,followtheseinstructions.
Retention Module Step 1. Open the two sides by folding them up.
Step 2.
Push the locks on top of the CPU
inward. Step 3. Insert the CPU into the retention
module. The CPU fits in the CPU slot in
only ONE way, do not try to force it in.
Step 4. After completely inserting the CPU, push the two locks on
top of the CPU outward. Now your CPU is ready for use.
To remove the CPU, press
the two notches on top of
the CPU inward. Now
press the two slides on the
retention module down and
remove the CPU.
