This may happen because sometimes the system does not recognized the one of the memory stick, please remove all your memory stick attached to the computer system, again reconnect that,this may result in recognition of an additional memory stick...

Have a look at what CPU-Z is reporting - see how all sets of RAM are actually being utilized.

In my experience, increasing my 4GB PC6400 RAM to 6GB PC6400 RAM cause a drop of 0.2 (5.8 -> 5.6) in the WE Index. I think this was because I'd dropped from 4-4-4-12 to 5-5-5-18. Tightening the timings a little allowed me to pull back to 5.7, but I haven't investigated further.

Nevertheless, it seems that beyond a certain amount, quantity is not an issue, but timings are.
