16GB Memory upgrade

[Stanschn]

I have a HP Envy x360 15-bp100 laptop with 8GB of memory.  I would like to upgrade the memory to 16GB.  I was hoping to just add a second 8GB memory module but it appears to only have one memory slot.  Do I have to remove and discard the 8GB memory module and install a 16GB memory module?

HP Envy x360 15-bp100 is not a valid/complete model/product therefore I can't find its REAL specs. I have to use the following similar model/product

              HP ENVY x360 - 15-bp100na

Which clearly says it has  4 GB DDR4-2400 SDRAM (onboard) RAM that means RAM is soldered down to its System board, non up gradable. Your machine could have 8GB of RAM and same boat.

The manual says some models/products have onboard RAM and a spare slot for additional RAM.

Thanks for the response.  The Model No of: 15-bp100 with no suffix is clearly printed on the back of my laptop.  I also could not find that model number online without a suffix but that is what is printed there.  I do have a product ID of: 1ZA15AV if that is of any help.  The system board ID is: 83C8 and System Board CT Number is: PGSRN2CNNB6035.  On the packing list it refers to the memory as a: 1ZA21AV  8 GB DDR4-2400 SDRAM (1x8 GB).  The tag on the existing memory module says: DIMM-CT: RGUMPGBTGB802Z.  If you can clarify any of this and tell me what I need to do to upgrade to 16GB I would appreciate it.  Thanks.

It is a CTO machine

Depending on what did you buy before, your machine can have one of the following System boards

1. 934998-001 MOTHERBOARD UMA i7-8550U
2. 934998-601 MOTHERBOARD UMA i7-8550U WIN
3. 934999-001 MOTHERBOARD UMA i5-8250U 4GB
4. MOTHERBOARD UMA i5-8250U 4GB WIN

Most likely 2 or 4

If 2 you can upgrade to 16GB using 2x8GB RAM

If 4 you can add 8GB to have total 12GB max

You should know what did you order because it is a CTO (Configure To Order) machine otherwise the only way to find out: open your machine.

But you are saying your machine has 8GB of RAM, looks like it has 4GB (onboard) + 4GB using System board #4 above, which is similar to the following machine

therefore you can replace 4GB with 8GB using

Note: You can use a tool call CPU-Z to see your existing RAM configuration. For example

   

My machine has 2 occupied slot, each 16GB of Samsung RAM ...
