Sorry, I cannot answer about rampage formula, but P5E runs without problems with AxeRAM 1066+ (4x1GB 1066MHz 1.90V 5-5-5-18). It runs with no problems with any BIOS I have tested.
hmm which BIOS does you board use? I haven't read through the whole thread as I don't really have the time to, but are many other people having that problem with 1066 RAM at stock speeds?
