I have 2 2GB sticks of patriot ram that are DDR2 1066. I have been trying for a while now to have them run at 1066, but have failed. My MB automatically sets them at 800 whether its dual or single channel, ganged or unganged. When i attempt to manually change the settings in BIOS (Timings, Voltage, etc.), my computer never boots. I guess I am really just lost as to where to start, whether it should be running in dual or single channel, and if it should be ganged or unganged in the bios. I would appreciate the help in setting up my bios so this runs at its maximum speed.
