　　4GB 2Rx8 512M x 72-Bit PC3L-10600 CL9 Registered w/Parity 240-Pin DIMM

　　DESCRIPTION

　　This document describes ValueRAM's 512M x 72-bit (4GB) DDR3L-1333 CL9 SDRAM (Synchronous DRAM), low voltage, registered w/parity, 2Rx8 ECC, memory module, based on eighteen 256M x 8-bit FBGA components. The SPD is pro- grammed to JEDEC standard latency DDR3-1333 timing of 9-9- 9 at 1.35V and 1.5V. This 240-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
