This document describes ValueRAM’s 512M x 72-bit (4GB) 
2Rx4 DDR3-1333 Registered w/ Parity CL9 SDRAM  
(Synchronous DRAM) ECC memory module, based on thirty-
six 256M x 4-bit DDR3-1333 FBGA components. The SPD is 
programmed to JEDEC standard latency DDR3-1333  
timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact 
fingers and requires +1.5V. The electrical and mechanical 
specifications are as follows:

CL(IDD)  

9 cycles

Row Cycle Time (tRCmin)  

49.5ns (min.)

Refresh to Active/Refresh  

110ns 

Command Time (tRFCmin)

Row Active Time (tRASmin)  

36ns (min.)

Power  

3.960 W (operating per module)

UL Rating 

94 V - 0

Operating Temperature 

0° C to 85° C

Storage Temperature  

-55° C to +100° C
