DESCRIPTION
This document describes ValueRAM's KVR26S19D8/16 is a 2G x 64-bit (16GB) DDR4-2666 CL19 SDRAM
(Synchronous DRAM),
2Rx8, non-ECC, memory module, based on sixteen 1G x 8-bit FBGA components. The SPD is programmed to
JEDEC standard latency DDR4-2666 timing of 19-19-19 at 1.2V. This 260-pin DIMM uses gold contact
fingers. The electrical and mechanical specifications are as follows:
