Sampling RAM chip for PA800. 128MB SDRAM EXB SODIMM 145
Any of the following types of symptoms could be an indication of bad SDRAM within the PA800.
The PA800 has two banks of SDRAM. Bank #1 consists of a number of ICs soldered onto the CPU board. Bank #2 is a removeable SODIMM module installed into a socket on the CPU board. Use the buit-in diagnostic test to check the SDRAM and determine which bank the problem is in.
A message indicating an error in bank #2 (Ram Bank 2/2 Buss Error) can safely be assumed to be a problem with the SODIMM module. Replacing the module. (part # GRA0002101) should solve the problem.
