I'm trying to upgrade my older Dell Dimension 4100 at home from 512MB ram to
1GB. The AIDA32 utility I use shows I have two DIMM slots each populated with
a 256MB PC133 non-ECC module. I purchased two 512MB PC133 non-ECC modules.
One, a Viking, is brand new and the other, no name showing, is used. I put
the new Viking in slot 0 and the used one in slot 1.
When I booted up, AIDA32 reported correctly that both slots were populated
with 512MB modules. But it also reported that total memory was only 512MB. So
I left the new Viking in slot 0 and removed the used one. At bootup, report
indicated that slot 0 was populated and slot 1 empty. I then pulled the
Viking and inserted the used one in slot 0. When I powered up I got 3 beeps,
and bootup process stopped.
Leaving the used in slot 0, I put the new in slot 1. Got a beep at powerup,
but bootup proceeded and XP started up. System says only 512MB total memory.
Rebooted and went into BIOS setup. It shows 512MB for whichever slot the
Viking is in, but Not Intitialized for the slot used module is located. (With
just the Viking in slot 0, BIOS reports 512MB for slot 0 and Not Installed
for slot 1).
I also tried the Viking 512MB in slot 0 and one of the two 256MB modules
which I know were working in slot 1. Bootup to XP went fine, but total memory
still reports only 512MB.
The AIDA32 report on the modules are identical (PC133, non-ecc,unregistered,
etc) with one exception. The Viking module's width is 72-bit, but the used
module is 64-bit.
So, I guess my question is: Is the used stick bad, or is it incompatible
with the 4100, or is the max memory for the 4100 only 512MB?
