Pros: Worked on my Gigabyte z390 ultra with 9700k as advertised. Set XMP and worked flawlessly.

Cons: None

Overall Review: Great product. I spoke to a Corsair rep prior to purchase due to this sku not being listed on Gigabyte's qvl list for my motherboard. Was told it would work and it did. I'm very satisfied. No hassle, no fuss.
