This document describes Kingston’s 128M x 64-bit 1GB 
(1024MB) DDR2-1066 CL5 SDRAM (Synchronous DRAM) 
memory module, based on sixteen 64M x 8-bit DDR2 FBGA 
components. This module has been tested to run at DDR2 
1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD 
is programmed to JEDEC standard latency 800Mhz timing 
of 5-5-5-18 at 1.8V. This 240-pin DIMM uses gold contact 
fingers and requires +1.8V. The electrical and mechanical 
specifications are as follows:

Clock Cycle Time (tCK) CL=5  

2.5ns (min.) / 8ns (max.)

Row Cycle Time (tRC)  

51.5ns (min.)

Refresh to Active/Refresh  

105ns 

Command Time (tRFC)

Row Active Time (tRAS)  

39ns (min.) / 70,000ns (max.)

Single Power Supply of  

+1.8V (+/- .1V)
