Review on OLOy DDR4 RAM 16GB (1X16GB) 2666 MHz CL16 1 by Cody Clark

This memory conforms to JEDEC specifications and does not contain XMP profiles. So the timings are a bit slack compared to other memories with similar speeds, but it also runs at 1.2V compared to the 1.35V you'd expect from memories with faster timings. I didn't spend time tweaking the settings to get a more accurate time as it didn't come with the computer that needed it. Heatsinks aren't required and add extra bulk to the modules, but this is the era we're living in with window computers all over the home improvement market. Good value for money when buying.
