Pros: Lots of tuning options, but...

Cons: ...I needed the wide tuning options to use anything but very commonplace memory. The BIOS is still a work-in-progress.

Pros: Low voltage, decent price

Cons: A lot of the new AM4 motherboards don't have built-in support for these modules. You have to hand-tune them, and even then, it can be difficult to get them to perform at spec. The heat spreaders honestly don't look as efficient as they could be. In retrospect, if I wanted to OC my memory a bunch, I would have gone with something that had fins on top, where the airflow can more easily dissipate heat from the module.

Overall Review: I can't recommend this memory -- not because it doesn't work as claimed, but rather because a lot of newer motherboard BIOSes simply don't recognize it yet, and have some trouble auto-setting the timings. If you don't know how to tune your BIOS memory timings, don't get this memory. If you do, you're probably fine, although you may want to go with another brand, with faster timings and a more logical heatsink design.
