Pros: -Great performance out of the box for people who don't want to tweak their memory (XMP) -Looks pretty awesome with the RGB not being over the top -Temperature sensors per dimm -Samsung B-die -Consistent binning between sticks I received

Cons: -They seem "cheaper" in feel and visually aswell as feel like they have less metal content than other heat sinks G.Skill do (e.g. Trident Royal, RGB). -My sticks in particular had negative scaling for tRCD apart from 1 of the 4 I received. E.g. the good stick did 4000 14-14-14-28 1.55v just fine. The rest of the sticks required 16 tRCD otherwise it'd be unstable. 4000 15-15-15 1.5v also worked, 1.55v doesn't due to the tRCD issue.

Overall Review: (FYI I would put 4 stars, accidentally clicked 5 and wouldn't let me change it back) Personally as someone who likes to get everything out of their daily had I known tRCD was going to have issues with vdimm I would not have bought them, or maybe I got unlucky it is silicon lottery after all, however... I feel it is in the push in the right direction regardless for G.Skill with them putting out more aggressive bins. I like the idea but fell just short from an overclocking stand point. On the other hand they'd be pretty perfect for people who want to set XMP and forget!

Pros: -Runs super fast and scales to 1.5v with ease for 24/7 usage -Runs really well on Ryzen 3000, I could tighten to as low as 3733 CL14-14-14-14-26-40-250(tRFC) in 1:1 -Fastest retail kit you can buy to date -Has a super premium feel, I almost didn't want to touch them it was like getting expensive jewelry! -A2 PCB

Cons: -Expensive (you can quite literally buy high end graphics cards for these prices) -RGB makes the sticks run a little bit hotter, since the chips are Samsung B-die they're temperature sensitive, so I'd recommend disabling RGB for best performance. -QVL'd on boards to run at XMP with Ryzen 3000 but won't do it. XMP is very CPU and motherboard dependent when it comes to super high binned kits such as this one. -Finger print magnets

Overall Review: I'd say for your day to day PC builder these are definitely not worth it, however if you're after every last MHz/tight timing as possible then these will be good for you if you have deep pockets. They are really spectacular in the right hands and absolutely fly given the right scenario especially if you're pushing extreme voltage. 10/10 for performance 10/10 looks 4/10 value
