HyperX Fury DDR4 Compatible RAM

[kufooru]

So this was a hard thread to title, since the question is kind of a complicated one.
The story is this: last year I upgraded my PC with a new mobo that turned out to be incompatible with the DDR3 RAM I already had from before, so I was forced into buying DDR4.
Since I was kind of tight on cash at that point, I decided to juts get one stick, with the intention of buying an additional one later on.
The RAM I bought was an 8GB Kingston HyperX Fury 2666MHz CL15 1.2V (Black), and I've recently started feeling the need to upgrade to 16GB.
The problem is that since then this seems to be the only model that they've (for some reason) decided to discontinue, and everything else on the market either has higher/lower speeds or different clocks. Essentially I'm seemingly left with nothing to pair my existing RAM stick with.

So my question is this:
Can I actually pair my existing RAM with anything available on the market, or am I better off just trying to sell it and buying 16GB of something else?

Actually yes, you'd be better of just trying to sell it and buying 16GB of faster RAM. It's possible to get faster RAM which would downclock to your present one but it's a gamble. Same Cl value and control chip would maximize chance for it to work properly.
If you have Ryzen system, it responds very good to faster RAM-

Yeah, I had a feeling that was gonna be the case...
In case you're wondering my specs are:

Asus Z170 Pro Gaming
Intel i5-6660k
GTX 1060

and of course the RAM I already mentioned.

What I don't understand is why it's impossible to find any information on, if that particular model of the HyperX Fury is just out of stock (and if/when they'll restock) or if it's just plain been discontinued (and if so, why).
