The main constraint is usually the amount of available RAM in the system.

It's a project aimed at raising funds for charity. You have plenty of components ready for a complete build, but you're unsure about the RAM choice. The official specs for the Dell Inspiron 560 state a maximum of 8GB (four slots) using an Intel G43 chipset, while Intel claims the G43 can handle up to 16GB DDR3 RAM. So, is it the chipset or the motherboard that's restricting things? Since documentation from Dell is unclear on this, you might need to verify with the manufacturer directly.
Which Windows release are you using? It seems x32 is limited to 4GB RAM, which might be the issue.
It indicates the manufacturer only verified up to that capacity, so don’t assume larger sizes will function. Typically, it should fit within the chipset limits—though some companies like Dell might restrict choices artificially, forcing you to purchase alternatives. Ultimately, compatibility depends on testing and experimenting with different RAM sticks. I’ve seen boards advertised as supporting only 4GB, yet 8GB performed perfectly, since bigger modules weren’t available at the time. Vendors seldom revisit older models to confirm their capabilities.
Really, I misunderstood how you were asking. You meant the system has 8GB but is capped at 4GB, right? That would suggest a Windows version. For your question, 16GB would be sufficient. Prebuilt models often list lower RAM specs as their maximum.
Intel chipsets had specific requirements for memory types. For DDR2, certain sticks labeled "AMD compatible" worked, while Intel-only options were limited to "DDR2 light / strict mode." With DDR3, compatibility improved, though sticking to 8 GB total was recommended. You could use 1 GB or 2 GB slots, but 4 GB was generally not supported due to 32-bit OS limits in Windows. Running Windows 7 would be feasible if the CPU was recent enough.
Yes, you require a server operating system that matches your hardware and drivers. The software must also include AWE support. My former workplace ran over 4 GB on 32-bit systems using Windows Server and SQL Server, which was the only solution I was familiar with at the time. ~Note: Using PAE-compatible Windows allows accessing more than 4 GB of RAM, though regular 32-bit programs are still restricted to a 4 GB virtual address space unless they support AWE.
I'm not certain how we got off to the topic of a 32bit OS, I am aware of the RAM limitations. The system in question will be powerful enough to run a modern OS. As it stands, the system does indeed support 16GB of DDR3 without issue, I just now needa C2Q CPU to complete it (ebay to the rescue...again)
