The computer recognizes all 8GBs of RAM. When using some memory hogging applications, the computer would barely pass 4GBs of usage.

Things I've tried:

  • I reseated the sticks with not much luck.
  • There is no "maximum memory" flag set in msconfig.
  • There is no "memory remapping" option in the BIOS.
  • I've updated the BIOS to the latest version.

I have 4 x 2GB sticks (DDR2 PC2-5300 ECC) in this Dell Precision T5400 workstation. The 2 recently added sticks are x4 organization and the original are x8. I'm not sure if that would make a difference.

Which OS are you using (specifically thinking of a 32bit or 64 bit OS since two memory hogging 32 bit applications would be more of less limited to 2GB each). –  Hennes Feb 5 '13 at 15:21

Note that it doesn't matter so much what the OS is, it matters what the applications are. 32-bit applications are limited to 2GB memory space in Windows in pretty much all circumstances, even on a 64-bit operating system. (Of course, if you're running a 32-bit operating system there's your problem right there...) There's also no guarantee that your software needs that much anyway! –  Shinrai Feb 5 '13 at 15:21

Also, just because the "memory hogging" applications dont go above 4GB, doesnt mean they need to go above 4GB. –  Keltari Feb 5 '13 at 15:23

Make sure you allow the JVM to take this much RAM. Look into heap-size related JVM arguments like -Xmx and how to specify those for your applications. –  Daniel Beck Feb 5 '13 at 15:33

it sounds to me like you dont have a problem at all... –  Keltari Feb 5 '13 at 15:35
