Capacities
Overview
What this part is for
The ADATA DDR4 2666 U-DIMM (AD4U266616G19-B) is the mainstream desktop module for Intel and AMD platforms of the DDR4 generation. It runs at JEDEC DDR4-2666 CL19 timings on 1.2 V, so it needs no XMP profile and no BIOS tuning to reach its rated speed.
Capacities to 32 GB per module let a two-slot board reach 64 GB without stepping up to registered memory. ADATA tests modules at the finished-module level and keeps DDR4 in supply for the installed base of desktops, all-in-ones, and entry workstations.
