Lenovo IdeaPad Y700 14-ISK RAM Upgrade Bootup Slow

RAM Upgrade Bootup Slow

I bought a new Lenovo IdeaPad Y700 14-ISK Laptop 2 days ago.

Configuration:

Intel Core i7 6700HQ CPU @ 2.60GHz, 2601 MHz, 4 Cores, 8 Logical Processors

Samsung 8GB RAM DD4-2133 (1066 Mhz) (Serial # M471A1G43DB0-CPB)

1TB HDD

2GB AMD Radeon R9 M375

Windows 10 64-bit OS

I bought a Crucial 8GB 260-Pin SODIMM DDR4 (PC4-17000) Memory Module, CL=15, Unbuffered, 2133 MT/S Speed, Non-ECC, 1.2V, x8 Based, 1024Meg x 64, Dual Ranked

I added this RAM to Slot 2.

Now it shows up Total RAM as 16GB.

The bootup time is unusually 15 seconds slower than original. Is my RAM upgrade correct?

Is there any other information I need to provide? Does my RAM's match?

Thanks very much for your help.
