I would like to upgrade my 6 year old laptops: E5430 and E5530

I had a look at the support page from DELL, it says that the maximum RAM is only 8 GB for both laptops. I check through the manual books of both models already. They say the same.

Here are the links:

https://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_latitude_laptop/latitude-e5530_...

Meanwhile, the IVY CPU should technically support 16 GB. I also saw many ads saying that the maximum RAM for these types is 16 GB. Is there any misunderstanding here?
