RAM modules

[lesliegug]

On my computer there is one 8 GB RAM  module. When looking at my product info  it says it Supports up to 32 GB (unbuffered) on 64-bit computers. My computer is a 64 bit. So can I put two 16GB DDR4 modules in my computer?

the rules are complex. But let me list some.

1. read the manual first for slot limits not just total max.
2. DDR4 matched set, same. sure. works and correct speed.
3. do not mix SKU means all same maker and p/n.
4. buy only certified DDR4,  from say Corsair or kingston, means they tested it in YOUR EXACT PC and is not generic.
5. In some cases BIOS upgrades needed.
6.

Hello
@lesliegug  your computer is this one?

HP Pavilion 690-0024 Gaming Desktop PC Product Specifications

It is mentioned installed (to be checked)

8 GB

• Amount: 8 GB
• Speed: PC4-21300 MB/s
• Type: DDR4-2666

Yes you can install 16gb memory
By adding a module identical to the original one, if the brand is different, this may work, but you need exactly the same reference
