Kingston´s 256M x 64-bit 2GB (2048MB) DDR3-1600MHz CL9 SDRAM (Synchronous DRAM) memory module, based on sixteen 128M x 8-bit DDR3 FBGA components. This module has been tested to run at DDR3-1600MHz at a low latency timing of 9-9-9-27 at 1.7V to 1.9V. The SPD is programmed to JEDEC standard latency DDR3-1333MHz timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers and requires +1.5V. The JEDEC standard electrical and mechanical specifications are as follows:
Features:
•JEDEC standard 1.5V ± 0.075V Power Supply
•VDDQ = 1.5V ± 0.075V
•667MHz fCK for 1333Mb/sec/pin
•8 independent internal bank
•Programmable CAS Latency: 5,6,7,8,9,10
•Posted CAS
•Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
•Programmable CAS Write Latency(CWL) = 7(DDR3-1333)
•8-bit pre-fetch
