The Kingston Value RAM KVR26S19D8/32 is a 4G x 64-bit (32GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 2Rx8, non-ECC, memory module, based on sixteen 2G 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. Main Features Power Supply: VDD = 1. 2V Typical DDQ = 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 Dual-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) Ro HS Compliant and Halogen-Free
