1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket
are in the "open" position. i.e. The handles lean outward. Slowly slide the
DIMM module along the plastic guides on both ends of the socket. Then
press the DIMM module right down into the socket, until you hear a
click. This is when the two handles have automatically locked the mem-
ory module into the correct position of the DIMM socket. To remove the
memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
1.11 Cache Memory
Since the second-level (L2) cache has been embedded into the Intel®
socket 478 Pentium® 4/Celeron™ processor, you do not have to take
care of either SRAM chips or SRAM modules. The built-in second-level
cache in the processor yields much higher performance than the external
cache memories. The cache size in the Intel ® Pentium ® 4 processor is
256/512/1024 KB. In the Celeron CPU, the cache size is 128/256KB.
1.12 Processor Installation
The AIMB-742 is designed for Intel Pentium® 4 processor/Celeron™
(socket 478)
Step 1 : Lift the processor socket lever
Step 2 : Align the corner having the triangle marking on the processor
with the corner where the lever is attached to the socket
Step 3 : Lower the lever to its original position
