120790 2003-02-13 03:38:00 A DIMM is a double sided SIMM. SIMM's are typically 32-bit (36-bit) data transfer, while DIMM's are twice that, at 64-bit.

SIMM's have a 72 pin connector, DIMM's have a 168 pin connector.

Uhmmm... probably more.

Talking about SDRAM that is.

Double sided does not necessarily mean chips on both sides either, but the PC board edge connectors are unique to each side, not "joined through" the board.

Your Motherboard will determine if you can use either.

120792 2003-02-13 09:51:00 For all practical purposes, SDRAM currently on sale will be single sided with 4 chips. This won't always work with older mother boards and will only show half the true value of RAM installed.

Double sided SDRAM as currently purchased is a minority product & not as widely available. It has 4 chips each side (hence "double sided") and is needed for some older boards, mine included.

The problem appears to be an inability of the motherboard to address the full RAM value from a single sided 4 chip stick. I took my two single sided 128MB sticks back (to DSE) swapped them for double sided and got my full 256MB showing where before I had only 128MB.

Given Godfather's history of accurate info he is probably right as well, but the issue could be different!
