Current BF deal on Amazon, looks like the cheapest price ever. I have a 2×8 GB in my Alienware m15 and the better timings (15-17-17-35) can make a significant difference over the standard timings (19-19-19-43) found on most OEM DDR4 that comes with laptops. The XMP profiles in them applied automatically for me (confirmed with CPU-Z), so it’s literally a 5 minute job to drop them in a laptop.
