upgrading memory

[oo-]

i've just tired to upgrade the memory on a pc from 256mb by adding another
256mb slot.
The pc has three slots for the memory (which btw is 256mb pc133 sdram) I
bought a new slot of memory same as the other but my PC won't recognize it,
i think from readign various bits on the net that the slot isn't compatible.
the only differenct seems to be their appearance with the original 25mb
memory having those black squares (sorry i don't know the technical term) on
both sides and the new memory only having them on one side.
whats the problem here?

Some memory will not be recognized by some computers (most common problem is PNY memory in Gateway computers). This can be caused by memory timing settings. Try setting your BIOS to default or most conservative settings. Also, the memory could be defective. The black things are the memory chips. It does not matter where they are physically located on the DIMM, but some motherboards will not work with higher density chips.

I'm running a program called aida32 to tell me whats in my system.
unde tth motherboard settings it has options memory and spd
in the memory it tells me my total is around 230mbish i think but in the
spd, it recognizes the both memory slots and the only difference is that the
new memory has only 1 row, 4 banks whereas the old memory had 2 rows, 4
banks.

when i first boted up after fitting the new RAM nothing happened but after a
while of fiddling around I got windows xp to start with the old memory in
dimm slot 1 and the new memory in dimm slot 3. and the fact that aida32
lists this meory as exisiting but it has not increased my total memory to
around 512mb as expected.

confused.

Return the new memory and go to crucial.com
and buy whatever they recommend for your
mobo. It's obvious that your mobo can't deal with
the new high density memory.
