Vista Memory Upgrade problems

by anthony.barnett / February 28, 2009 3:38 AM PST

I am attempting to upgrade my Dell desktop from 2GB to 4GB. I get the dreaded "Blue Screen" after the new RAM module pair is installed and the machine reboots. Dell has checked out all my hardware and even replaced the motherboard and CPU. Is there a problem with using more than 2GB of RAM while running Visa? My RAM configuration is a pair of 1GB RAM. The machine is relatively new and came Vista capable.

Some very fine details are required.

1. The make, model, version, bios version of that Dell.
2. The make, exact model numbers of those 2GB memory sticks.
3. The BIOS settings for Vram and timing.

Sorry, its all very technical and the devil is in the details.

Be aware that many off the shelf sticks of RAM do this. I stick with Crucial when it matters.

D5 = PC2-4200 (DDR2-533 @ CL=4) Voltage: 1.8V (

"Bios Settings for VRAM: 667Mhz" (you.)

Sorry, it shouldn't work. Your new ram is only 533Mhz.

That is odd. Perhaps I've given you bad info on the vram bios. I ordered the ram from dell using my model info so there would be no compatabilty problems. So you are telling me that the ram is not working due to the 533 vs 667 speed? Is there a module that I can use thst will work? Thanks Bob

The "D5" if you had the "E5" ram then we wouldn't be focusing on something so basic.

Sorry but I would not count on this RAM to work or work well.

No, but...

Is there a problem with using more than 2GB of RAM while running Visa?
-> No, but Windows 32-bit cannot utilize all of the 4GB. Also, the new RAM could be bad. Try installing one stick of RAM at a time and see when the system fails. (Be sure the computer is off and unplugged while adding/removing any internal components.) You can also download, burn to CD, and boot to Memtest86 to test the RAM for errors/defects.
