memory - Use more than 2 GB RAM in Dell OptiPlex 320

A while ago I purchased 2 × 2 GB Sticks of RAM for my Dell OptiPlex 320. 
When I inserted them,
I was greeted with a series of beeps, and a system that would not boot. 
I checked each stick, and individually they work, just not as a pair.


If I insert one 2 GB and one 1 GB, then the BIOS detects both
(reporting 3 GB installed: 1 × 2 GB and 1 × 1 GB) and will boot,
but Windows (8.1.1) can utilise only 1 GB. 
How can I get both sticks to work, thus giving me 4 GB RAM?



  • The sticks in question are identical Kingston KVR533D2N4/2G modules
    and do not have ECC.

  • The system is a July 2007 one,
    and the technical specifications
    list it as being capable of using up to 4 GB.
