[SOLVED] Ram upgrade to 4Gb problems

[gerard4143]

Hi,
I'm having problems upgrading to 4Gb of RAM. The problems isn't the installation of the chips, or booting and running SUSE 10.3. The problem is I lose my network connection when I upgrade. Thats right everything works fine except I can't access the internet.

My system: Acer m1100 AMD athlon_64 (Acer tech docs says it can address up to 8 Gb of memory) and I am currently running SUSE 10.3.

Has anyone had a similiar problem? Does anyone know a solution?

Note the previous RAM chips were 512MB 1Rx8 DDR2-667MHz-CL5 PC25300U-555-12-D0
and the new chips are 2GB DDR2-667-CL5 PC2-5300U-555

Also: the system runs fine with only one 2GB RAM chip installed. The problems start when I install the second 2GB RAM chip for a total of 4GB then the system will boot and work properly except I have no access to the internet.

Thanks...Gerard4143

4GB RAM upgrade...The saga continues...I can upgrade the system mentioned above to 3GB and everything works fine(internet is O.K. with 3GB)

That is 2x512MB + 1x2GB. If fact I'm sending this message with this configuration

That is odd

Are you running 64bit or 32bit OS??

32 bit is limited to addressing 3Gig the top gig is reserved. But that really should not effect anything but the total memory you can address.

With 64bit the limit is well above anthing you can stuff into a machine.

You should report this to Suse.

I'm running 64 bit SUSE 10.3. The problem isn't the OS(at least I don't think it is)
it sees and reports 4GB of ram and runs fine, its I just cannot establish a internet connection with 4GB of ram(if switch to a lower RAM value i.e. 1GB, 2GB, or 3GB I can connect to the internet). This is the mystery, why would the OS and software run on 4GB of RAM with no problems except the internet connection failing. I'm lost do you have any advice?

I don't have a clue. Best you can do is try some basic trouble shooting

Test the new memory. One stick may be bad.

How are you connecting to the internet? What chip sets?

It was the on board network card. Yeah I know, why would it work with less than 4GB of RAM and fail with >= 4GB of RAM...I don't know. All I know is, I installed a
a new network card...and the problem disappeared...Thanks for listening Gerard4143
