HP Pavilion 17-e019dx - could I install 12 Gb memory (4+8) ?

According to the product description,  HP Pavilion 17-e019dx might have up to 8Gb memory installed (alltogether, using 2 slots)

However, according to the maintenance manual, it has 

Support for DDR3L (1600 MHz) dual channel

Support for DDR3L-1600 MHz single channel (for use on computer models equipped with an AMD A6-5200, A4-500,
or E1-2500 processor)

Support for up to 12288 MB of system RAM in the following configurations:
 12288 MB (8192 MB x 1+ 4096 MB x 1), not supported for use on computer models equipped with a 32 bit OS

I have windows 8.1 x64; will this laptop be able to accept second memory chip (8gb)?

Thank you!
