"Intel® Optane™ memory is a smart, adaptable system accelerator for your new 7th Gen Intel® Core™ processor-based computer."
Not even adnotation or asterix that it is not working with Pentium 4600. Now I have useless 16 GB card.
Read what you just wrote, man. The Pentium 4600 is not an Intel Core, it's an Intel Pentium.
Return it or sale it online somewhere? I've read some people use Intel Smart Response Technology with optane if their system isn't compatible. It's not as fast or smart, but you can make it work.
