Dell Optiplex 320 problem with RAM and PCI-E

[mpiotrek_w]

Hi,



I put 4GB RAM 667MHz into my Optiplex 320 and it worked fine untill I installed GeForce 9400GT graphics card on pci-e slot. Now computer boots very very very slowly, somthing strange happend to my graphic card drivers - I can not install them properly... Where is ther problem? I am sure that my new grapic card is good because I have tested it on second computer. When I am working on integrated card everything is ok.

If there is a problem with my mainboard( DELL 0CU395) is there any solution? Is there any other mainobard which I can put into my computer instead of this one? If there is such mainboard which wolud fit in my computer and it will be working with 4GB of RAM and PCI-E graphics card installed, write down its model



thanks in advance

I am very very pissed at dell technical support.
In technical specification or users guide there is no info about this limitation(4GB RAM does not work properly with PCI-E card installed)!!!

It seems to be a dell hardware problem, but they are not going to fix it!!!

I just discovered the same issue when upgrading RAM on a Optiplex 320 machine. I tried with two different PCI Express video cards and a regular PCI card. No Luck. The cards worked perfectly with 2 GB RAM installed.
