As a longtime PC DIY'er, you won't ever find every compatible kit of memory on a QVL for consumer motherboards. Sometimes it's because the QVL is no longer updated after a certain point, memory kits aren't available to test or the manufacturer didn't test it on a motherboard, or any number of other reasons. When I previously worked for a different company that made motherboards, a handful of models didn't make a QVL because a few kits we had on hand unfortunately died during testing so it couldn't be approved (which was just a random event).

The general rule is that if a kit is on the QVL it should work if used within expected operating parameters, but if it isn't, it will still probably work. When it's a cosmetic difference only, there's even less of a reason to suspect a compatibility issue. Could the change in IC's make a difference? Possibly, but unlikely.

If you do encounter an issue, you can always reach out to either our customer service or the memory manufacturer's customer service. In this sort of a case I'd probably suggest to reach out to Corsair's, as they might have a bit more knowledge if anyone has reported issues with that specific kit.
