Re: Rampage and memory issues
By your assigned problem my assumption is that this is an Asus motherboard.
If you have 6 memory slots, this means it is running in triple channel mode which means it wants three memory channels to match. Hence the 3 black and 3 red.
As this is part of there ROG Overclocking boards they can many times be very picky on detecting RAM and being able to utilize it proper.
I can only say I have only heard of 1 person ever get two different sets of RAM to work on those motherboards.
My recommendation would be to run Sell the 3 sticks of 2GB and buy another 4GB stick of the exact same you have and run them togather
