Windows XP does not recognize new RAM

I have a Dell Precision WorkStation 530 Workstation with 2 sticks of 128MB.  I bought an additional 2 sticks of 512MB PC800 from crucial.com.  Windows does not seem to recognize the ram.  BIOS recognizes it but the system properties only sees 256 no matter what I try.

I tried only using the 2 sticks of 512, and windows only sees 256.   I tried with all 4 sticks in and tried rotating and alternating the locations.  No matter what I try windows will only recognize 256.

Then I did a crucial scan (when I had the 2 512s) and it correctly recognized the 1GB - yet windows wouldn't.  Any ideas?

Try a repair install of XP after adding the memory.

How much physical memory does it show in the task manager? Do you have the latest bios update. It is version 11. Also do you have the dell chipset driver installed?

I would run a RAM mem test from

memtest.org to see what is recognzed.

Either the RAM may be faulty or incompatible, or there are other issues.


Also you might try a Live Linux CD to see how much RAm it shows.

I hope this helps !

Did you install it in pairs? That Precision WorkStation 530 has four "pair-banks". You will find hints at dell or at http://www.memoryx.net/3115801.html -> "Purchase and install in pairs. Do not mix ECC with nonECC memory"

try the SIW software, and check under the RAM see whether it is recognized :

If it get recognized, that mean is the XP Operating System problems, suggest to run the repair or reinstallation for XP .........

did you check if that ram is compatible for your mobo ?  check on www.crucial.com
also - try using the same ram - not all mobo's work well with mixed ram

it turned out to be a bios setting that limited the amount of RAM that the computer could use.
