HP ProBook 450 G4 memory configuration

[TheMonk-1]

Hi ...

I'm looking for memory upgrade for a HP ProBook 450 G4.
It was delivered with a single 8192 MBytes Samsung module DDR4-2400 (1200 MHz) model M471A1K43CB1.

According to Crucial this upgrade should be 100% compatible with HP ProBook 450 G4.
Replacing the Samsung module with 2 * 16GB modules CT16G4SFD824A for a total of 32 GB
https://www.crucial.com/memory/ddr4/ct16g4sfd824a/ct9506474

But according to other specs on the net maximum memory for the ProBook 450 G4 is 16GB (2 * 8GB modules)

So should I consider choosing a 1 * 8GB module in addition to the existing Samsung module?

Please advice

Thanks in advance

On page 2 of the manual says machine has

Two customer-accessible memory module slots supporting up to 16 GB of RAM
Supports dual-channel memory
PC4-17000, 2133-MHz, DDR4 SODIMMs

NOTE:450 models run at 2133 MHz; 455 models run at 1866 MHz  (455 machines use AMD processors).

Supports the following configurations:

• 16384 MB (8192 × 2; dual channel)
• 12288 MB (8192 + 4096; dual channel)
• 8192 MB (8192 × 1)
• 8192 MB (4096 × 2; dual channel)
• 4096 MB (4096 × 1)

In many cases, Crucial gives good options but not 100%.  Yes, you can add 8GB to slot 2 using same existing RAM on slot 1.

Hi Banhien

Thanks for your response

So your advice is to go for a 8GB module same specs (of course) as the existing module and preferably same brand(?)

I think it is misleading or at least incorrect when Crucial on this site states max memory as 32GB:
