ACTICA  is a high speed DDR3-1333/1066 Registered ECC DIMM. It is designed for mission critical application memory solution. This DIMM includes Error Checking and Correcting (ECC) for maximum  reliability.  The  modules  is  constructed  using  Samsung  SDRAMs,  and  is  fully  compliant  with JEDEC specifications. Decoupling capacitors are mounted on the PCB board for better signal integrity. The DIMM feature serial presence detect (SPD) based on a serial EEPROM device using the 2-pin I2C protocol.
