Hi I have 4 gb of ddr4 memory in my xc 330. How much can I add and what memory do I need

Specs say: Supports DDR4 1.2V 2133 unbuffered DIMMs (2GB, 4GB or 8GB) single channel up to 16GB total memory. So it depends on whether your 4GB is one stick or two. I think it likely to be one 4GB stick, so a second one gives 8GB, and 8GB instead gives 12GB and replacing it with two 8GBs give you 16GB.
