I have using a PC with Intel motherboard DP55WB for a while. I have 4GB of RAM total with 2 DDR3 1333 MHz sticks at both Channel A and B at DIMM 0 sockets. I wish to upgrade the RAM to 16 GB total. When I tried searching for recent specs, I found there are lot of RAM sticks with higher speed and voltage.
From this link http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000006516.html http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000006516.html I realize that DP55WB doesn't support speed higher than 1333MHz. Also Intel has never tested higher capacity memory spec, see link http://www.cmtlabs.com/2012/mbSearchResults.asp?sManuf=Intel&sMem=DDR3&sMN=DP55WB&oSubmit=Search http://www.cmtlabs.com/2012/mbSearchResults.asp?sManuf=Intel&sMem=DDR3&sMN=DP55WB&oSubmit=Search.
Would would be safe to buy 2 8GB memory stick of "Vengeance® — 8GB DDR3 Memory Kit (CMZ8GX3M1A1600C10)" link http://www.corsair.com/en-in/vengeance-8gb-ddr3-memory-kit-cmz8gx3m1a1600c10 http://www.corsair.com/en-in/vengeance-8gb-ddr3-memory-kit-cmz8gx3m1a1600c10. It says:
Speed Rating PC3-12800 (1600MHz)
SPD Speed 1333MHz
I am not sure what they mean? Can someone please advice.
I would advise you to do one of two things:
1) Go to crucial.com and enter your system information into the RAM advisor. I'll bet it recommends Crucial DDR3-1600 (PC3-12800). I have used this on motherboards that only support DDR3-1066 and DDR3-1333. You won't see any benefit out of the faster speed, however. Crucial memory is usually available in a few different latencies, e.g. a CL of 7, 9, or 11, with the lower numbers providing the best performance, but you will probably need to go into BIOS and explicitly enter the faster speeds (7-7-7-24, 9-9-9-24, or 11-11-11-x; look on the stick label for the exact values). The more expensive, the lower (faster) the CL.
2) Buy Corsair XMS3 DDR3-1333 (but not the one with a punked-out heatsink) which is still available at Newegg. I have had 100% success with them.

There are posts in this and other forums complaining about over-clocker memory. They're fine in motherboards that support the listed speed, but they sometimes present a problem on older motherboards.
Here are the officially supported memory sticks: http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000006516.html System Memory for the Intel® Desktop Board DP55WB.
The recommended memories for Intel® Desktop Board DP55WB are DDR3 1066 and 1333MHz at 1.5V. The maximum amount supported is 16GB.
