No, you should not mismatch the DDR3 RAM.

Signs of incompatibility can vary from slower performance, odd actions, crashes or BSODs, to the whole system failing. Generally, it’s not an issue if the machine functions at all, but these symptoms still shouldn’t be ignored. To reduce uncertainty, you might want a specific set of components. DDR3 running at 1200/2400 requires a well-chosen selection just to reach those speeds, and I’m aware your configuration should meet the requirements. However, there’s no certainty beyond the manufacturer’s specifications, which are already based on stock standards. That’s why I emphasize the need for a good “bin” of parts. While there can be minor differences in certain tests (like benchmarks), most PC1600 or PC2400 sets perform adequately. If you spot a reasonably priced highly-binned option, consider it. Otherwise, 1600 should suffice and get the job done.
It’s clear—either it will function or it won’t. Just give it a shot; if problems persist, opt for a 1600MHz model.
Thank you for the assistance! I’ll purchase the matching set—it turns out it’s from 1866. Enjoy!
