Going from 4 to 5 you wont see the difference at all. When I finally got an AMD quad I got some 1066 5-5-5-15 Pi's and added them to my Blacks and ran the lot at 5-5-5-15 800. As long as the RAM matches voltage and the CAS is set to the slower batch then it should be no problem at all. I used to do the same thing for DDR 400 sticks on my 939 rigs.
