This document describes Value RAM's KVR26N19S8/8 is a 1G x 64-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1 Rx 8, memory module, based on eight 1G x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2666 timing of \n 19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical & 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 & dynamic on-die termination (ODT) for\n- data, strobe, & mask signals\n- Low-power auto self refresh (LPASR)\n- Data bus inversion (DBI) for data bus\n- On-die VREFDQ generation & 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 & 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 & address bus\n- PCB: Height 1.23&157; (31.25mm)\n- Ro HS Compliant & Halogen-Free Feature Feature Value Internal memory 8 GBInternal memory type DDR4 Memory clock speed 2666 MHz Component for PC/server Memory form factor 288-pin DIMMMemory layout (modules x size)1 x 8 GBBuffered memory type Unregistered (unbuffered)ECCNCAS latency 19 Memory ranking 1 Memory voltage 1.2 VModule configuration 1024M x 64 Row cycle time 45.75 ns Refresh row cycle time 350 ns Row active time 32 ns SPD profile Y Halogen free Y Product colour Green Cooling type Heatsink Lead plating Gold Windows operating systems supported Y Mac operating systems supported Y Linux operating systems supported Y Ro HS compliance Y Operating temperature (T-T)0
