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 \n19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:\n\n- Power Supply: VDD=1.2V Typical\n- VDDQ = 1.2V Typical\n- VPP - 2.5V Typical\n- VDDSPD=2.2V to 3.6V\n- Nominal and dynamic on-die termination (ODT) for\n- data, strobe, and mask signals\n- Low-power auto self refresh (LPASR)\n- Data bus inversion (DBI) for data bus\n- On-die VREFDQ generation and calibration\n- Single-rank\n- On-board I2 serial presence-detect (SPD) EEPROM\n- 16 internal banks; 4 groups of 4 banks each\n- Fixed burst chop (BC) of 4 and burst length (BL) of 8\n- via the mode register set (MRS)\n- Selectable BC4 or BL8 on-the-fly (OTF)\n- Fly-by topology\n- Terminated control command and address bus\n- PCB: Height 1.23” (31.25mm)\n- RoHS Compliant and Halogen-Free
