Dell XPS 400 Ram upgrade problem
I have a Dell XPS 400 with 4 512MB ram sticks (original) for a total of 2GB ram. I decided to upgrade this to 4 1GB ram for a total of 4gb ram.
- When I inserted the new ram and restarted, I got the bios beep codes: 1-3-2.
- I switched back to the old ram, and all was fine.
- So I switched to the new ram and confirmed it was seated - same problem.
- So, I updated the bios to the latest version - same problem.
- So I reset CMOS by switching the jumper per instructions - same problem.
The old working ram is:
- 533 MHz, Dual Interleaved, DDR2, SDRAM
The new non-working ram is:
- 667 MHz, DDR2, SDRAM (Dell p/n: SNPU8622CK2/2G)
The new ram is listed as compatible for this system using the service tag number on the dell support site.
My guess is that the memory speed isn't supported by the motherboard, but most sites list 533 and 667 as being supported for a Dell XPS 400. I don't really want to pay shipping or restocking fees every time to try another ram and return it.
Is there any way I can get a definite answer as to what memory is supported on my specific motherboard?

I have an XPS400 with 4GB of 667 ddr installed. The basic specs of the ram are compatible. If it's dell branded ram, it's unlikely to be a specification problem. I would try the ram one stick at a time with no other ram installed. Some of it may work.

Thanks - yes, it is Dell branded ram. I forgot to mention: I also tried inserting the ram one stick at a time to see if it would work - No dice.
The part number on my motherboard is listed as: 316736100010_R01)A00. An additional number underneath that one is: CN-0FJ030-70821-623-F09K.

Doh! - I should have tested them all. Just did a retest and found that 2 of the 4 sticks were bad. I'll just return the 2 bad ones for replacement.

and in the meantime, 3GB of ram isn't so bad... you'll only ever get around 3.5gb max out of it anyway, even with a 64bit OS, owing to the chipset.

Is the 3.5G of max memory confirmed with the chipset? I have an XPS 400 that I just installed 4-1G sticks of RAM into (ordered from Dell web site). I am running Ubuntu 8.10 x64 edition, and a "cat /proc/meminfo" shows:

Windows XP now reports 3.75 GB of RAM in the System Properties (after replacing the two bad sticks of RAM). I was expecting about 3.5 GB due to the limitations, but since I'm running several Virtual Machines, I wanted to make sure I get as much as possible. It's working fine now.

I don't believe you understood what I was saying. I am running a 64 bit OS and it can not see all 4G of ram even though the XPS 400 specs state the system can have that much. I was curious if that has been verified to be a limitation of the chipset.
