I was trying to update the SPD of my Black Cellshock DDR3 sticks. I have one pair of 1800 and one 1600 ... Both with D9GTR .
My problem started when i tried to boot them on my rampage 2 extreme board. They refuse to post . Lcd poster show something like "locked" ...

I tried to make a more compatible SPD to the RAM with spdtool & thaiphoon burner . Tried in X48 & X58 boards with no success.
What happening is that these programs only update half the SPD (Lower half in screen as you see it in Spdtool or thaiphoon) .
The part that is updateable has the info on XMP (Tried to make some XMP profiles but still RAM doesn't play in rampage2extreme) .
I have to edit the timings but i just can't write them (spdtool gives verify errors) . The memories seems to be protected from writing .

I found the following link that might be usefull ...
