DESCRIPTION SPECIFICATIONS *Power will vary depending on the SDRAM used. KVR26N19S8/8 8GB 1Rx8 1G x 64-Bit PC4-2666 CL19 288-Pin DIMM Continued >> FEATURES This document describes ValueRAM's KVR26N19S8/8 is a 1G x 64-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx8, memory module, based on eight 1G x 8-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: CL(IDD) Row Cycle Time (tRCmin) Refresh to Active/Refresh Command Time (tRFCmin) Row Active Time (tRASmin) Maximum Operating Power UL Rating Operating Temperature Storage Temperature 19 cycles 45.75ns(min.) 350ns(min.) 32ns(min.)
