ADATA AD4U266638G19-S 8 GB (1x8GB DDR4-2666)

The ADATA AD4U266638G19-S 8 GB comes as a single module with 8GB of DDR4 on board. Operating voltage sits at 1.35V. It is specced for 2666 MT/s with a CAS latency of 19, working out to a true latency of about 14.3ns. Once memory clears 3600 MT/s, frequency gains taper off, so the 8GB on offer here is the spec that counts for esports and everyday use.
