Can someone tell me what type of memory I have. From the info I gathered I
am guessing its double sided because it has two banks of 256MB but am not
100% sure. What I found is this:
Bank 1: DIMM Synchronous DRAM 512MB/72

Then under Logical/Chipset 1 Memory Banks it says
Bank 0 256MB DDR-SDRAM 2.5-3-3-7 1CMd
Bank 1 256MB DDR-SDRAM 2.5-3-3-7 1CMd

Memory Module 1
Manufacturer Xerox
Type 512MB DDR-SDRAM
16x(32Mx8)

Thanks.

Your guess is probably correct, but is it really that difficult to open up
your computer case and take a look at the memory modules?

If each DIMM has memory chips on only one side of the DIMM's printed circuit
card then it's single sided. If it has memory chips on both sides of the
DIMM's printed circuit card then it's double sided. No guessing required.

The terms 'single sided' and 'double sided', originally meant exactly
this. However they should really now be 're-defined' as 'single banked',
or 'double banked'. The question is whether the memories appear as a
single memory bank to the computer, or use two CAS lines, effectively
appearing as two complete memory assemblies on one module. Unfortunately,
some memory sizes and makes, can be 'double banked', yet only have chips
on one side of the module. This has happened at odd intervals through the
history of memories, when larger memory technologies appeared, and the
manufacturers have implemented them in this way, to provide 'reverse
compatibility'.
Looking at the modules, _does not_ guarantee the right answer.

Indeed.. also modules can have chips on both sides and still be single
banked.
