The difference in speed shouldn't cause you any grief. How many RAM slots are available and what is the size of your power supply unit?
Each of my channels has three slots. Would it recognize the RAM if I only put in two modules?The Crucial Adviser is generally quite accurate. What it does not take into account is a user trying to mix RAM brands/specs as per this case.
If the OP tries using only the 3X2GB set from Crucial I believe the issues will be resolved.
Actually, I never even thought of doing that. If it DOES turn out to be my Elpida and Crucial sticks not getting along, I could just keep my Elpida modules out of my system! I will try that and post back with the results. Thanks!Yes you can use two RAM sticks and that will put you in Dual Channel.
Have you tried using the 3 Crucial sticks by themselves? That would give you 6GB and Triple Channel operation.
Do I clear the CMOS by resetting BIOS to factory settings? Would that affect any data stored on my computer?Remove all the RAM-clear the CMOS-Install one stick of the Crucial RAM and see what happens. Repeat with each stick of Crucial RAM.
