There is far more than just the BIOS involved -- the mainboard is likely engineered to support 8 G of RAM total, regardless of what the chipset and CPU support. This is not a high-end, high-performance system and wasn't designed to be one. It's a mid-range multimedia system, and price constraints being what they are (people will literally choose one model over another with as little as a $5 price difference), it's been designed to meet a price point.
Very few notebooks have extensively tune-able BIOS settings - for that you need to go for an enthusiast system. They're out there - but not at the price of an Inspiron.
Inspiron 15R (5520) is designed to support maximum of 8GB of memory. This is the reason why when you install the memory sticks of 4GB and 8GB separately they work fine. But when they are inserted together, it is not reading the entire amount as 12GB. I would also request you to help me with the source of information which suggested 12GB upgrade on the computer.
I have same problem. I upgrade the original 8G to 2X8G Corsair PC12800, windows can detect 16G. But it's slower than before and the CPU usage is higher too.
Need your help in the same regards as I purchase the same model with 4 Gb ram but now I want upgrade 8 gb means total is 12 gb this will work or not please let me know.
I have dell inspiron 15r 5520, system tag (6YX5MV1) with 4gb ram and i want to upgrade so i just wanted to confirm that can i upgrade to max 8gb or 16 gb??

Hi Allan D,
I was just trying. I thought that since Ivy Bridge supports up to 32GB RAM the laptop will be able to handle the 12GB with no issues.
Anyways, thank you for the information. At least I have my peace of mind now ;)

I chatted with two technical support reps today and both stated that the Inspiron 15R (5520) can support up to 16GB RAM

The official limit is 8G -- more may work, or may not -- it's not supported officially.
If you have 4G it's likely 2X2, so you'd get 10G if you replace one 2 with an 8.
