8GB (4GB 1Rx8 512M x 64-Bit x 2 pcs.) PC4-2133

 

CL15 288-Pin DIMM Kit

 

This document describes ValueRAM s KVR21N15S8K2/8 is a

 

kit of two 512M x 64-bit (4GB) DDR4-2133 CL15 SDRAM

 

(Synchronous DRAM), 1Rx8, memory modules, based on eight

 

512M x 8-bit FBGA components. Total kit capacity is 8GB. The

 

SPD is programmed to JEDEC standard latency DDR4-2133

 

timing of 15-15-15 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

 

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 1.23” (31.25mm)
