I have a dual core intel pc. I original have 2 GB memory DDR 2, I added 2 GB more of the same brand and specs. I have windows 7 installed, when I check computer information, its only showing 2 GB, it should show 4 GB. Is the other card faulty? I checked the new card alone, its being detected by the system, but if placed together, it shows 2 GB only.
Could not detect both memory stick
Since you have checked the new memory and its being detected by the system if placed alone, then its working. You are working with windows 7, I am assuming that you have windows 7 32 bit since only 2 GB has been detected. That is a usual system info show up for 32 bit. You system could be using 4 GB, but it will only show 2 GB in the system info.
Its your option to reinstall or upgrade to windows 7 64 bit so system can maximize and display the 4 GB memory card you placed. I am using 64 bit right now and i have 8 GB and its showing in the system info. This is the only solution for windows 7 issue with not showing more than 2 GB memory.
Or your computer does not support 4 GB max memory, check your bios for this. I hope this helps. See mine below. I am using windows 7 64 bit with 4 GB memory.
