ValueRAM 4GB DDR4 2666MHz Desktop Module
This document describes ValueRAM's KVR26N19S6/4 is a 512M x 64-bit (4GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx16, memory module, based on four 512M x 16-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:
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
8 internal banks; 2 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 1.23” (31.25mm)
RoHS Compliant and Halogen-Free
