 Additional Procedures 5500—Software Installation Errors and L2 Cache Identification 

 

If the logic board is an OPC, follow these instructions to 

positively identify the L2 cache DIMM as compatible or 

incompatible:
1 View the back of the cache DIMM.
2 Notice that there is one larger chip and eight smaller 

chips. The eight smaller chips are organized in tow 

groups of four at each end of the DIMM.

3 Look at the markings on any one of the smaller chips. 

They will look similar to this:
IDT 74FST

32384Q (This number is the identifying factor.)

F9637BFU
If this number, not counting the Q or any other letters 

present, has five digits, it is compatible with OPC.
