RAM Upgrade Failure

Hi everyone. I just bought my 4/5-year-old Lenovo 3000 N200 (XP 32-bit) a ram upgrade - it had 2 1GB sticks of DDR2 so I bought two 2GB sticks. When I start the laptop, it stays stuck on its manufacturer logo splash screen.

I guess it might need a BIOS update? Or the laptop's just not equipped to handle that much RAM, despite what the manufacturer's specs say (which would be the first time I've had that happen). I've never had this sort of problem with ram, if anything the POST beeps and I re-seat a not-quite-in stick and that solves it.

The only difference between the old and new sticks, apart from being 1 or 2 GB, is that the old ones say "128M 64" and the new ones are "256m 64". I don't really know what that is or if it would cause this problem.

32-bit x86 RAM limit

In non-PAE modes of x86 processors the RAM memory is always limited to 4GB.

Limits on memory and address space vary by platform, operating system, and on Windows by whether the IMAGEFILELARGEADDRESSAWARE value of the LOADED_IMAGE structure and 4-gigabyte tuning (4GT) are in use.

Limits on physical memory for 32-bit platforms also depend on the Physical Address Extension (PAE), which allows 32-bit systems to use more than 4 GB of physical memory.

PAE and 64-bit systems can address up to the full address space of the x86 processor.

I would first of all try reseating the RAM or one stick at a time.

I get the difference between 32-bit and 64-bit, the basics anyway.

I have tried each stick at a time, and in each slot, but no joy. I have reset all BIOS settings and services to default, no change there either.

The Events log has this error code that doesn't seem relevant when I looked up the code:

The DS1410D service failed to start due to the following error: The system cannot find the file specified.

Have you tried removing the old ram and replacing it with (1) stick of the new- if so- what happened?

What does the above actually mean?

According to Lenovo`s "maintainance service manual" the maximum ram your machine can handle is 2 GB which can be either 2 x 1GB or 1 x 2GB stick of the correct type

Cheers HC

Hmmm, both MrMemory and Crucial say 4GB max (2 x 2GB sticks) for Lenovo 3000 N200
