Hello Yangorang,
I am sorry to know about the issues you encountered.
Regarding RAM, it would be interesting to know more details about the memory sticks you are using like the voltage when using 1600MHz XMP and the SDRAM organization. I may suggest you to verify if the memory complies with such SDRAM organization based on the article or TPS document below; we also recommend using 1.5v (perhaps setting the RAM values manually) and updating your BIOS. Otherwise you may get a completely different memory model that complies with the motherboard requirements (from the tested memory list).

Regarding the mSATA Intel® 525 SSD, I can only suggest to make sure there is enough heat dissipation from proper airflow inside the chassis. In case the issue persists with this drive please contact your local Intel® support team for further assistance.
