Cache Memory
Celeron processors have the L2 (Level 2) cache built into their architecture, so
there is no need for an L2 cache on the motherboard. The Celeron processor
has a physical L2 cache size of 128KB and a cacheable memory area of 512MB.
4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors (300 through 400MHz) can be used on the
Tomahawk BX/A+. Please refer to page 15 for the correct CPU jumper settings for
your CPU. Remember:
•
The CPU is a sensitive electronic component and it can easily be damaged
by static electricity. Do not touch the CPU pins with your fingers. You
should be able to insert the CPU into the socket with virtually zero force.
Do not press down hard on the CPU as you will bend or break pins.
Pin 1 on the CPU is
denoted by a small dot
on one of the corners
and Pin 1 on the ZIF
socket is denoted by an
angled corner. Never
force a CPU into a
socket. Forcing a CPU
to seat will bend the
pins on the CPU and
possibly damage the
motherboard. Check
with your vendor or
manufacturer for proper
voltage selection.

Push down lightly on the CPU, and lower the arm on the ZIF socket to secure
the CPU. A squeaking noise is normal as the arm lowers. After the CPU is
securely seated, install the appropriate cooling device. Tyan strongly
recomends a heatsink/fan combination. Consult with your case manufacturer
for other cooling options.
