Kingston HyperX Blu DDR3 1600 PC3-12800 4GB CL9

This document describes Kingston´s 512M x 64-bit (4GB) DDR3-1600 CL9 SDRAM (Synchronous DRAM), 2Rx8 memory module, based on sixteen 256M x 8-bit FBGA components. This module has been tested to run at DDR3-1600 at a low latency timing of 9-9-9-27 at 1.65V.The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9. This 240-pin DIMM uses gold contact fingers. The JEDEC electrical and mechanical specifications are as follows:

FEATURES

• JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply
• VDDQ = 1.5V (1.425V ~ 1.575V)
• 667MHz fCK for 1333Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 9, 8, 7, 6
• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
• Programmable CAS Write Latency(CWL) = 7 (DDR3-1333)
