what is double sided memory...I think that is what my problem is. I have
purchased 2 sticks of 256 ram.. It is only being read as 128 for each of
them. How do I purchase double sided ram? What is it called and about how
much is it. I have already spent over 100.00 for these 2 sticks of ram.
"Double sided" memory refers to RAM modules that have RAM chips on
both sides of the circuit board.
With PC133 SDRAM, which is where the confusion and problems arise,
there are actually two different types of modules. One type is the
original low density or double sided type and the other is the new
high density type where RAM chips are only on one side of the circuit
board (single sided).
Older motherboards are quite often not capable of using the high
density modules properly and will only recognize half of the capacity
of these modules.
You have to search specifically for these modules, as there is not
that great a demand for them now and many dealers to not stock them.
They are also quite a bit more expensive than the high density
modules.
It is also possible that your motherboard requires PC100 rather than
PC133 SDRAM. You need to check the detailed specifications for your
board and also to identify exactly what type of RAM is installed in
the computer at present. Often, but not always, there is a small
adhesive label affixed to the RAM module that gives the specifications
for that module.
PC100 RAM modules are also hard to find, and like the low density
PC133 may have to be special ordered. You can also purchase them
online through memory specialists such as Crucial (
www.crucial.com) or
Kingston (
www.kingston.com).
Good luck
