Kingston 8GB (1x8GB) DDR4 SODIMM 2666MHz CL19 1.2V Unbuffered ValueRAM Single Stick Notebook Laptop MemoryThis document describes ValueRAM's KVR26S19S8/8 is a 1G x 64-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx8, non-ECC, 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. This 260-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows: ? Power Supply: VDD = 1.2V Typical? VDDQ = 1.2V Typical? VPP = 2.5V Typical? VDDSPD = 2.2V to 3.6V? Nominal and dynamic on-die termination (ODT) for data, strobe, and mask signals? Low-power auto self refresh (LPASR)? Data bus inversion (DBI) for data bus? On-die VREFDQ generation and calibration? Single-rank? On-board I2 serial presence-detect (SPD) EEPROM? 16 internal banks; 4 groups of 4 banks each? Fixed burst chop (BC) of 4 and burst length (BL) of 8 via the mode register set (MRS)? Selectable BC4 or BL8 on-the-fly (OTF)? Fly-by topology? Terminated control command and address bus? PCB: Height 1.18' (30.00mm)? RoHS Compliant and Halogen-Free
