Here is your ASUS P7P55D Motherboard RAM Specifications:
4 x DIMM, Max. 16 GB, DDR3 2200(O.C.)*/1600/1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
Supports Intel® Extreme Memory Profile (XMP)
Your motherboard has a maximum of 16GB of RAM divided into 4 slots, each slot can handle a 4GB of RAM at max.
In Other word, the following specifications is what you need:
- Memory Type : DDR3
- Clock Speed : 2200(Overclock) OR 1600 OR 1333 OR 1066
- Registered/Unbuffered: Unbuffered
- Error Checking: Non-ECC
What you have done is that you've inserted 2x 8GB RAMs, into 2 slots which exceeded the max RAM capacity for each slot, and that's your problem. So, you have to change them to a 4x 4GB RAM if you want a 16GB. the one you have are compatible, but it should be 4x 4GB, rather than 2x 8GB !
Once you do that, your system should recognize the full 16GB of RAM and everything is going to work just fine.
If understood you correctly, you have a problem with your RAM, If you just upgraded your rams, then you have to make sure that the RAMs are compatible with your Mobo, if is it compatible, then you can try to plug them off, and re-insert them again, and that could fix the problem. Remember to do that while your computer is unplugged from the power source, and if possible, unplug the power connectors from the motherboard before you put your hands on anything, this will make sure to do it correctly. – iSR5 – 2014-10-16T08:43:54.000

You can check your motherboard manual, and see what type of RAM supported. If you can tell me what motherboard you have, I can tell you which RAM it supports and what is the best choice for it to work perfectly. Also, tell me which kind of rams you have or if you ordered online, you can just give me its page. – iSR5 – 2014-10-16T09:24:48.283
