The notebook is HP EliteBook 735G and AMD R5 2500U.

I bought a DDR4 2400 note (16GB*2) with a lifetime warranty of Kingston HyperX, with low delay. At first, there was no problem. As a result, the blue screen was displayed three or four times a month, and it was found that it failed after the memory test. After the return period, you can't return it. After Kingston was officially sold, it could not be solved.

Put Hyper-X note in an old Dell notebook, the processor is i5 7200U, and the memory test passed.

I just bought the cheapest DDR4 2400 silver bar in JD.COM with a lifetime warranty. Just finished the memory test on AMD 2500U and passed. Good pit.
