BL465c-G1 detects 4GB RAM only from installed 6GB

- OS: Windows2003-R2-Standard
- boot.ini file with /PAE
- Memory DIMMS are installed in in pair (2X1GB) in banks (A,C,D) with bank B not populated.
- Two processors are installed
- Online diagnostic report shows 6GB as installed in those banks.
- Windows system memory shows that memory installed = 4GB only !!!

Any idea please?

Windows 2003 R2 Standard only supports 4GB of RAM, you need Enterprise Edition if you want to use more then 4GB.

Thank you for this information. In this case, what is the purpose of the /PAE (Physical Adress Extension) that is used with W2003 Ent. & Std editions?

PAE is only usefull when you install Windows 2003 Enterprise, and even then, it's somewhat flakey.

For best results, install Windows 2003 Standard x64, that will take advantage of all 8 GB and won't add the added cost of the Enterprise version of Windows 2003.
