In my vast knowledge,(HAHA), I attempted to add SDRAM Memory to my computer,
only thing was what I didn't understand was the computer that I removed the
memory from is a different PCvalue. I have here a PC133U 64 SDRAM board
but it is not the same as what I put in the other computer, I can't
remember what it is now, some other PC value, that computer is not at my
finger tips right now.
Thanks,

Was there a problem or a question in there? I'm going to put on my
psychic cap and try some predictions:

PC133 memory was sold in 168pin DIMMs and 72pin SIMMs.

The 168pin DIMM modules are 64-bit, and on Pentium 1/2/3/4 systems,
the external data path is 64bits wide, so you can put these in as
singles if you wanted. no need to match stuff, except to have the
memory type be the same. In this case, SDRAM, probably non-parity
modules. If you mix different speeds of SDRAM, the system should just
default to the slowest one.

The 72pin SIMM modules have to be installed in pairs on Pentium
1/2/3/4 systems, as those modules were 32bit. While the Pentiums are
32bit processors, they (as mentioned) have a 64bit external data path,
so you need to install these modules in identical pairs. Same speed,
same parity, same memory type, and while not an absolute necessity,
same brand would be helpful too.

like I have much to go on.

You sure?! I could have sworn it was Professor Greengage in the Potting Shed
with the Hosepipe. Oh well...
