MEMORY ADDERSS LINE FAILURE

[Sonia]

I have a DELL OPTIPLEX GX100 and I am trying to upgrade
my memory. I checked the memory specs before buying and
it was dell recommended chips. When I installed the 128mb
chip with the 64mb chip the machine gave an error on
reboot saying: "memory address line failure .........
Decreasing available memory." In the bios settings it
says there is 128 mb installed. After shuting down I
removed the old 64mb chip and rebooted. On reboot I got
continual beep errors and nothing on the screen. I then
switched the banks that the 128mb chip was in and tried
again, and got the same beep error. I then removed the
128 and installed the 64 (tried 2 slots) and everything
was fine and recognized 64mb of memory.
Anyway, I have tried to place the 64 and 128 in the
machine .Everytime I reboot it comes up with only 128
memory in bios.
What am I missing here ?
What's the problem ?
How do I fix it get the 196RAM instead of 128 with error
and beeping on boot or 64RAM only?

Sounds like the 128MB module is bad. Possibly, it's
just incompatible with the 64MB module. To find out
about compatibility, download "AIDA32 - Personal"
from: http://www.aida32.hu/aida-download.php?bit=32
and install and run it. Click on the '+' next to
"Motherboard", then on "SPD", then on each "Device
Description". The characteristics it lists for your memory
modules should match, except for size.
