During the past days i tried some things , like wiring the WP pin to Ground (VSS) and unsoldering the WP leg from the PCB with no effect . SPD was still protected .

So .. now i'm gonna try one more thing . I found 2 pin compatible EEPROM chips from some DDR2 memories (and electricaly compatible according to the PDF) ... and i succesfully flashed them with the refererence D9GTR SPD .
Now , all i have to do is desolder the EEPROM's from the DDR2 pcb & solder them to the DDR3 pcb (Of course after desoldering the existing ones from my cellshock DDR3) .

In the next days i'm gonna have the news ... and i believe it's gonna work .

The EEPROM i'm gonna use are "AT34 - U1 c" . It's from Atmel .
