Advantech PCA-6185 Manuel D’Utilisation

automatically locked the memory module into the correct position of the 
DIMM socket. To remove the memory module, just push both handles 
outward, and the memory module will be ejected by the mechanism in the 
socket.

Since the second level (L2) cache has been embedded into the Intel® 
Pentium® 4 processor, you do not have to take care of either SRAM chips 
or SRAM modules. The built-in second level cache in the Pentium® 4 
processor yields much higher performance than the external cache memo-
ries. The cache size in the Intel® Pentium® 4 processor is 256 or 512 KB, 
depending on the type of CPU. 

The PCA-6185 provides socket 478 for an Intel® Pentium® 4 processor. 
The CPU on the board must have a fan or heat sink attached, to prevent 
overheating.

To install a CPU, first turn off your system and remove its cover. Locate 
the processor socket 478.
1.

Make sure the socket 478 lever is in the upright position. To raise 
the lever, pull it out to the side a little and raise it as far as it will go.

2.

Place the CPU in the empty socket. Follow the instructions that 
came with the CPU. If you have no instructions, complete the fol-
lowing procedure. Carefully align the CPU so it is parallel to the 
socket and the notches on the corners of the CPU correspond with 
the notches on the inside of the socket. Gently slide the CPU in. It 
should insert easily. If it does not insert easily, pull the lever up a 
little bit more.
