This document describes ValueRAM's KVR24S17S6/4 as a 512M x 64-bit (4GB) DDR4-2400 CL17 SDRAM (Synchronous DRAM), 1Rx16, memory module, based on four 512M x 16-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2400 timing of 17-17-17 at 1.2V. This 260-pin SODIMM 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 1.18” (30.00mm)

• RoHS Compliant and Halogen-Free

• 2.5"
• 480GB
• SATA III

Incredible Speeds Plus Rock-solid Reliability

The A400 SSD is an excellent choice for users who are looking to upgrade their system to an SSD. With incredible read/write speeds, it dramatically improves the responsiveness of your existing system with incredible boot, loading and transfer times compared with mechanical hard drives.

The A400 SSD operates quietly and is shock- and vibration-resistant for rugged reliability when used in notebooks and other mobile computing devices. 

10x Faster than a Hard Drive

Powered by a latest gen controller for read and write speeds up to 500MB/s and 450MB/s1, the A400 SSD is 10x faster than a traditional hard drive1 for higher performance, ultra-responsive multi-tasking and an overall faster system.

Rugged Construction. Cool & Quiet Operation.

The A400 SSD is built with Flash memory. There are no moving parts, making it less likely to fail than a mechanical hard drive. It's also cooler and quieter, and its shock and vibration resistance makes it ideal for notebooks and other mobile computing devices.

Slim Form Factor

The A400 SSD has a 7mm form factor to fit in a wider array of systems. It's ideal for slimmer notebooks and in systems with limited available space.
