Reliable model.
Works in 4200MHz mode or lower. Probably a mistake on my part when selecting my motherboard and RAM kit.
I've never yet managed to saturate the 64GB in my kit. I chose it for its low latency specification, and that's exactly what I got from this point of view.
The absence of coloured LEDs is another plus.
The manufacturer, Corsair, has a reputation for reliability when it comes to RAM kits. A reputation I can confirm here.
