FEATURES
This document describes ValueRAM's KVR26N19S6/8 is a 1G x
64-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM),
1Rx16, memory module, based on four 1G x 16-bit FBGA
components. The SPD is programmed to JEDEC standard
latency DDR4-2666 timing of 19-19-19 at 1.2V. Each 288-pin
DIMM uses gold contact fingers. The electrical and mechanical
specifications are as follows:
