Patriot Signature Line 4 GB (1x4GB DDR4-2666)

The Patriot Signature Line 4 GB comes as a single module with 4GB of DDR4 on board. It is specced for 2666 MT/s with a CAS latency of 19, working out to a true latency of about 14.3ns. Operating voltage sits at 1.35V.

Once memory clears 3600 MT/s, frequency gains taper off, so the 4GB on offer here is the spec that counts for esports and everyday use. Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this mid-range DDR4 option easy to justify. Its $96.99 price tag places it squarely in mid-range territory.
