RAM - same RAM manufacturer, but different manufacturing date and possibly chip manufacturer - could it possibly cause problems?

I have the same model number, RAM company is the same as well, XMP timings and XMP frequency is obviously the same as well (and voltage rating as well), but the manufacturing date is different and possibly chip manufacturer might be different.

So long as the manufacturer says the memory is for your computer (it appears so), then it will work fine.

To your specific question, there will neither be a computer performance boost, nor any kind of degradation. The memory is specifically for your computer.
