What does double-sided ram look like?

I'm trying to return incompatable PC100 SDRAM ram that I just bought and I
will not get a refund unless I can prove that it was not MY error in buying
the wrong product.
I'm not too savvy about ram etc but what I can say is that the key
difference between the ram sticks I bought and those that were functioning
well on my machine is that my originals had eight
little 'blocks' along one side whereas the new ones only had 4.
I've heard of double-sided ram (or something like that) and I wanted to ask
is this what it looks like? If so, I don't believe the manufacturer stated
this on the product description, which might be my case for getting my money
back. But I want to be sure of this before I make a complaint. The product
descripton was as follows:

Module Size: 128MB
Package: 168-pin DIMM
Feature: SDRAM, PC100
Configuration: 16Meg x 64
DIMM Type: Unbuffered
Error Checking: Non-Parity
Voltage: 3.3V
SDRAM Timings: CL=3

Is there anything in this description that I didn't understand properly
before buying the wrong sticks?

Thanks,

Joanna

The description is incomplete in that it doesn't state the
number of "devices" (i.e., chips) on the module. Low
density modules have 16 or 18 chips, and have them on
both sides, since there isn't room for more than nine
chips on a single side. A careful retailer should have
stated the number of chips, although many do not.

You might check your computer manual or use the
memory confugurer tool on http://www.crucial.com or

memory your computer needs. Buy brand name
memory; pay an extra dollar now and avoid headaches
down the road.
