memory

Hello group,

I apologize if I am not in the correct newsgroup and please direct me if
this the case: but,

Is there any good reason why two seemingly identical memory sticks will not
work together although individually work just fine? I was attempting to
upgrade the memory in the machine below and I ran into that problem.
Previously had 1 stick of 256MB....item number CT32M64S8D7E.BLT. Purchased
the following:
1GB 2 X 512MB PC133 100 SDRAM 133MHz DESKTOP RAM MEM

As mentioned, individually each one works perfectly but whenever I
attempt to boot with both installed I get a system32 error message regarding
drivers. (sorry for not having the exact error message.) thanks in advance
for any help that you can provide.

I have not had a lot of trouble with this and normally, I can mix different
brands of ram with no problem. However, yours is not an uncommon
problem--sometimes it just happens. Since it appears that you bought your
ram as a set of two sticks, they should work together and should be under
warranty.

Board: Intel Corporation D845WN AAA64181-300

The Winnipeg board uses an 845 chipset.

ftp://download.intel.com/support/motherboards/desktop/d845wn/A6513601.pdf

( http://developer.intel.com/support/motherboards/desktop/d845wn/sb/cs-008943.htm )

The Intel chart says, that with SDRAM, the 845 can use a maximum of 3x1GB.

http://www.intel.com/design/chipsets/mature/index.htm

What OS are you using ? It is really WinXP, or some earlier OS ?

For example, Win98 has an issue when more than 512MB is present.
There are some workarounds for that.

With both sticks installed, use another test environment, to verify
the RAM is OK. Try memtest86+ from memtest.org for example. You
can follow up on that, by booting a Linux LiveCD, such as Knoppix,
as proof that some OS works with your new hardware configuration.
This version of Linux, boots from the CD, so doesn't need to be
put on the hard drive at all.

http://www.knopper.net/knoppix-mirrors/
ftp://mirror.switch.ch/mirror/knoppix/ (use 5.1.1CD for example - you'll need a
burner program that handles an ISO9660
format image)

I think on my Asus P4B (845 based) board, I still have 3x512MB of PC133 in it (total 1.5GB).
So the 845 can work with all slots full.

Thanks all. I just went with adding the one 512 stick and another stick of
128 i had to the 256 already in the machine. I'll go with this for now.
since 2 512 sticks just don't seem to work together...I'll find another
machine to put it in. thanks for all your help.
