Hello,
I am wanting to upgrade my RAM from the memory stick that is included in the computer out-of-the-box.
I have an HP Pavilion 690-0020 Gaming Desktop PC.
The product specifications for this device are confusing and unclear.
Here is a link to the they Product Specifications: https://support.hp.com/us-en/document/c05970262?jumpid=reg_r1002_usen_c-001_title_r0001
The specifications say that the computer comes with 1 8GB stick of Type DDR4-2666 included.
However, then the specifications say for Memory Upgrades that it supports DDR4-2400 RAM.
Already, this is confusing. How does the computer come with DD4-2666 RAM, but it only supports DDR-2400 RAM?
My main question is this: I would like to upgrade to 16 GB (2 8GB sticks) of DDR4-3200 RAM. Would this be supported? Would it work at all, and would it work correctly, or would the speed be throttled?
Basically I do not understand how the specifications say "Supports PC4-19200 (DDR4-2400)" when it comes shipped with PC4-21300 (DDR4-2666) RAM. It is extremely confusing what is supported and what isn't, and I would love to get DDR-3200 RAM for this computer.
Thank you.

Yes, that is true because 2666 MHz will automatically run at 2400MHz on its motherboard. System may accept 3200MHz RAM but still auto down to 2400MHz
Its specs clearly says it supports 2400MHz RAM
https://support.hp.com/au-en/document/c05970262
and supports 4 GB and 8 GB DDR4 UDIMMs that means 16GB max. But a third party vendor says the following pair would work

Thank you for your reply! I am still left with 2 questions:
1) Why the computer come stock from manufacturer with 2666 RAM if it is down clocked to 2400?
2) The specifications say:
- Supports 4 GB and 8 GB DDR4 UDIMMs
- Supports up to 4 GB on 32-bit systems
NOTE:
32-bit systems cannot address a full 4.0 GB of memory. - Supports up to 32 GB (unbuffered) on 64-bit computers
How would it support up to 32 GB if it only has two slots for memory, and the specs say it only supports 4 or 8 GB sticks? This is conflicting is it not?
I understand you are saying a third party claims two 16 GB sticks would work but regardless of that, I am confused how the specifications say 32 GB is supported but only through 4 or 8 GB sticks when there are only 2 slots. This seems like an error in the official specification documentation, no?
Thank you for your assistance!

Product specifications CLEARLY STATE "Supports up to 32 GB (unbuffered) on 64-bit computers" (https://support.hp.com/au-en/document/c05970262)
I'm really concerned about what, exactly an "HP Expert" is considering the number of WRONG responses you have provided to many, many questions on here.
Can someone please explain what an "HP Expert" is if someone with that designation is consistently providing BAD information?

The specifications are riddled with typos. The RAM that came in mine is NOT 2666 as stated, but is 2400 as expected.
I am running 2x 16GB sticks for a total of 32GB, so I am 100% certain that it can handle 32GB.
