Upgrading NVME SSD and RAM on HP 15-AU171TX

[Tarikul]

In 2017, I purchased HP Pavillion 15 series laptop.

Now I want to upgrade my laptop's SSD and RAM,

I have 2 ques. for upgrading those modules.

1st one is: Does it support NVME SSD's?

2nd ques is: Does it support 2400 MHz DDR4 ram?

I already check Maintenance and Service Guide and I saw there it supports M2 SATA 3 only. There is nothing about NVME SSD. But I want to upgrade a faster SSD like Samsung NVMe SSD 960 PRO.

Sorry but the answer to both questions is negative. The M.2 slot only supports SATA M.2 not NVME. And further, please open the laptop and inspect before buying an M.2 SSD. Many models in this series do not actually have the M.2 slot to the left of the hard drive as shown in the Manual. It actually uses DDR4-2400 SO-DIMM but "bridges" (i.e. downclocks) it to 2133 mhz and will not go faster. Max memory will be 2 x 16 = 32 gigs. 

Please accept as solution if this is the info you needed even if not the answer you wanted to see.

I opened my laptop before, I saw a slot that was exactly like the image below.

The actual image is taken from youtube (disassemble of HP Pavilion 15 bc018ca)

 Then why my laptop won't support NVME or it's supported but the manual is wrong? 

I just want to ensure everything before buying new products.

Its not supported. It has to do with how the M.2 port is connected into the motherboard. SATA only.
