I'm building a PC using PC Part Picker and I planned to use my Intel Core i7-4770 3.4 GHz Quad-Core Processor because it has Quick Sync, which I need. However, I also have some spare DDR4 OLOy RAM sticks (16GB total, 2x8GB), and I noticed that PC Part Picker claims they aren't compatible. Is this a mistake, or is there a real issue? I can't find any info suggesting Intel CPUs have restrictions against specific RAM types.

The i7-4770 actually requires DDR3 RAM, not DDR4. It might be confusing, but the older Intel CPUs, like the 4770, just aren’t compatible with DDR4. You’ll have to stick with DDR3 for that processor.
The i7-4770 is quite outdated—it’s from around 2013. It supports only DDR3 memory, which is why your DDR4 RAM isn’t recognized as compatible. You'll need to look for a motherboard that can handle DDR4, which typically pairs with newer Intel chips.
To clarify, the i7-4770 only works with DDR3. If you're planning to use any DDR4 RAM, you'll need a newer CPU that supports it, like those from Intel's 6th generation onward.
