upgrade memory. why no QVL list for motherboard 339A, from a HP Compaq Pro 6300 SFF pc?

[piablo]

i am looking for the QVL(Qualified Vendor List - which is a list of hardware that has been tested for compatability for any part - in my case, the motherboard/memor) list for my motherboard 339A, serial number [personal info removed].
Why is info not readily accessible, so I at least have a start with a checklist?
I am ready to buy some memory CMZ32GX3M4X1866C10R Corsair Vengeance RAM: 1866Mhz in XMP or 1333mhz in SPD; set 32gb (4x8gb) 
I want to see if it is compatible with my hardware.

Hi:

This is a peer-to-peer forum.  We don't work for or represent HP, so no one here would be able to answer your question.

The only memory part numbers that HP provides are what were originally offered in the model series, which you can find at the link below.

Gadgets SFF IPSM_Win8_690364-002.fm (hp.com)

Memory modules (PC3-12800, CL11)
* 8-GB   689375-001
* 4-GB   671613-001
* 2-GB   671612-001

I would not recommend buying the memory you have picked out.

For one thing the memory will only run at a max speed of 1600 MHz, so an 1866 MHz chip will bridge to a slower speed.

This is the aftermarket memory that Crucial recommends for your PC.

That's what I would recommend.

Thanks so much, @Paul_Tikkanen. Sorry if I came across bluntly. I appreciate community and peers helping each other out.

I need to get 4x8gb for web development work. Unfortunately what Crucial is publicly offering is a set of 2x8gb.  I'll try calling them tomorrow and see if they actually do have 4x8 sets, and maybe they will help me find an alternative manufacturer if they don't.
 
Have a great morning/day/evening!!

You're very welcome.

You should be able to either buy 2 sets of 8 GB or 4 x 8 GB individual sticks.

You can get it on Amazon too.

I used the same memory in my Dell Optiplex 7020 PC which uses the same DDR3L-1600 memory.

Works great.

It looks to be less expensive to buy 4 x 8 GB individually on Amazon than any of the other options.

You have a great evening too!
