I've had them in the drawer since 2010, the ProMOS kit is from 2007...right when supply of D9 was dwindling. I bought the D9s second-hand.
I can't remember exactly what they need for 500 CL4 and 600 CL5, but it was quite a bit. I could barely do 800 3-3-3-5 @ 2.4v with them. The ProMOS kit doesn't touch CL3, but does 4-4-3-5 up close to 550.
