Is this what doublesided ram looks like?

[Joanna]

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

Which vendor is this? If they aren't willing to accept a return,
at least they should accept an exchange for memory that will
work in your system.

I think you may be thinking of Double Data Rate (DDR) memory. The physical
location of the memory chips on the memory should not really mean anything,
some memory has all the chips on one side, and some has it on both sides.
Does the memory physically fit in the slot?

Older chipsets are limited in the amount of memory they can
see per bank. E.g. Intel's BX chipset is limited to 128MB
per bank, so a 256MB module must be double-sided (or at
least be organized into two banks of 128MB each, instead of
one bank of 256MB).

In addition, older chipsets are limited in the size of individual
memory chip they can use. The problem with the original poster
is, her modules are using 4 x 256Mbit (32 Megabyte) chips,
and her chipset cannot handle them. She'll need to exchange
them for modules that use 8 x 128MBit (16 Megabyte) chips.

Not absolutely true.

Many motherboards have limited support for double-sided RAM modules
with specific rules on the number and physical configuration when it
is used. It's also common for boards not to support mixing of
single-sided and double-sided.
