I have currently 4 memory sticks with which only 2 of them are recognized
Kingston DDR3-1333 KVR1333D3N9/4G 4GB x 2
Kingston DDR3-1600 KVR16N11/4 4GB x 2
Here comes the spd register dump:

Does anyone know what is going on? Thanks Jack

It looks, to me, like CPU-Z is registering all 4 sticks of RAM, but I've never worked with CPU-Z myself. What do you see if you look at system properties? Does it show 8 or 16 GB there?
 
Dear alow,
It shows 16GB in CPUZ, but showing 8GB in system boot string and windows 7 system properties.
I've asked in ASUS support forum. Some said they are not on the QVL. But after a few examinations, I found their names are actually on the list. I've shuffled the RAM with various combination and also updated and flashed back the bios to no avail.
Thanks
Jack
 
make / model motherboard please, and any or all hardware info will/may help

was not unusual, in my day, for a motherboard to bork at mismatched ram.

Win 7, how much RAM dose computer have
Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.
In the System section, next to Installed memory (RAM), you can see the amount of RAM your computer has.

Note
In some cases, Windows reports both the amount of memory that's installed on your computer and the amount of memory that's usable. If you're using a 32-bit version of Windows, the amount of usable memory might be less than the total amount of memory installed.
