I had exactly the situation you described. 4 GB of RAM worked great at 800MHz but when I increased to 8 GB I had to lower speed to something like 533 MHz otherwise system was very unstable. In my case Intel Core 2 Duo E6600. I contacted the RAM manufacturer and this was their recommendation as well.
