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.
